Buffy and Addy launch their rockets at the same time. The height of Buffy’s rocket, in meters, is given by the function f(x) = -4. 9x^2 +50x ,where x is the number of seconds after the launch. The height of Addy’s rocket, in meters, is given by the function g(x) = -4. 9x^2 +25x +34 ,where x is the number of seconds after the launch. Algebraically find the moment when the rockets are at the same height, and then use that to calculate the height? Round to the nearest hundred.
PLEASE SHOW ALL WORK!!
The rockets are at a height of 83.15 meters after 1.36 seconds. Rounded to the nearest hundred, this is 83 meters.
To find the moment when the rockets are at the same height, set f(x) = g(x) and solve for x:
-4.9x2 +50x = -4.9x2 +25x + 34
50x = 25x + 34
25x = 34
x = 1.36
Therefore, the rockets are at the same height after 1.36 seconds. To calculate the height, plug x = 1.36 into either function:
f(1.36) = -4.9(1.36)2 +50(1.36)
f(1.36) = -4.9(1.85) + 68
f(1.36) = 83.15 meters

If you toss one dime and roll one die. Predict how many time you would flip heads and roll an odd number In 120 tries.
We can predict that in 120 tries, we would expect to get heads and an odd number around 30 times. However, it is important to note that this is just a prediction and the actual number of times this occurs may vary due to chance.
When flipping a dime, there are two possible outcomes: heads or tails. Similarly, when rolling a die, there are six possible outcomes: 1, 2, 3, 4, 5, or 6. An odd number is any number that is not divisible by 2, so the odd numbers on a die are 1, 3, and 5.
The probability of flipping heads on a dime is 1/2, and the probability of rolling an odd number on a die is 3/6 or 1/2. To predict how many times you would flip heads and roll an odd number in 120 tries, we can use the multiplication rule of probability.
The multiplication rule of probability states that the probability of two independent events occurring together is the product of their individual probabilities. Since flipping a dime and rolling a die are independent events, we can multiply the probability of flipping heads and the probability of rolling an odd number to get the probability of both events occurring together.
So, the probability of flipping heads and rolling an odd number is:
P(heads and odd) = P(heads) x P(odd)
P(heads and odd) = (1/2) x (1/2)
P(heads and odd) = 1/4
We can estimate that in 120 trials, we should get heads about 30 times and an odd amount about the same. It is crucial to keep in mind that this is only a prediction and that there is a possibility that the actual frequency of occurrence will differ.

(12 points ) Find the area of an equilateral triangle with side length 2cm. Show all necessary calculations. Round your answer to the nearest hundredth.
The area of the equilateral triangle with side length 2cm is approximately 1.73 cm².
What is the area of the equilateral triangle?An equilateral triangle with side length 2cm can be divided into two right triangles with hypotenuse equal to 2cm and the other two sides of length 1cm each.
We can then use the Pythagorean theorem to find the length of the height of the equilateral triangle, which is also the height of the right triangles.
Let h be the height of the equilateral triangle, then:
h² = 2² - 1²
h² = 3
h = √3
The area of the equilateral triangle can be found using the formula:
Area = (base × height) / 2
Since the equilateral triangle has three equal sides, the base is also equal to 2cm. Therefore, we have:
Area = ( 2 × √3 ) / 2
Area = √3
Rounding to the nearest hundredth, we get:
Area = 1.73 cm²
Therefore, the area of the equilateral triangle is 1.73 cm².

A long wire is wound to a circular coil of radius 1m and consists of 70 loops of wire around it
The resistance of the coil is given by R = N x ρL = 70 x ρ x 0.0897 = 617.9 x ρ ohms.
The length of the wire is equal to the circumference of the circular coil. The circumference C of a circle of radius r is C = 2πr, so for the circular coil of radius 1m, the length of the wire is 2π x 1m = 6.28m.
The number of loops around the coil (N) is 70. Therefore, the length of one loop is L = 6.28/70 = 0.0897 m.
The resistance of the coil (R) is equal to the resistance of the single loop multiplied by the number of loops (N). Therefore, R = N x R', where R' is the resistance of a single loop.
The resistance of a single loop is equal to the resistance of the wire per unit length multiplied by its length. Therefore, R' = ρL, where ρ is the resistivity of the wire and L is the length of one loop of the wire.

The new Iphone was reduced from $320 to $224. By what percentage was the price of the Iphone reduced? 7.4D A. 33% B. 96% C. 70% D. 30%
Answer:
D
Step-by-step explanation:
To calculate the percentage decrease in price, we need to find the difference between the original price and the reduced price, divide that difference by the original price, and then multiply by 100 to express it as a percentage.
The original price of the iPhone was $320, and it was reduced to $224. Therefore, the difference between the two prices is:
$320 - $224 = $96
To find the percentage decrease, we divide this difference by the original price:
$96 ÷ $320 = 0.3
Finally, we multiply this result by 100 to express it as a percentage:
0.3 × 100 = 30%
Therefore, the answer is D. The price of the iPhone was reduced by 30%.

2.)
[tex]R = 5/13[/tex]
[tex]S=12/13[/tex]
Step-by-step explanation: sin represents the ratio between a side opposite to an angle and the hypotenuse. It is important to learn these ratios as they allow for you to solve for side lengths in a triangle and angles. We were in this case finding the ratios. A lowercase letter represents a side length opposite to the angle. So to find R we would just need to divide r by t. In the first example, it would just be 16/34 which simplifies to 8/17. Do the same thing for s, and it would be for 30/34 which simplifies to 15/17. Repeat the same steps and you should get 5/13 for R and 12/13 for S.

A bisector in math is a line or a line segment that divides an angle or a line segment into two equal parts.
What is bisector?The bisector, also known as the perpendicular bisector, is a geometric concept in mathematics that is used to construct a line that is perpendicular to a given segment and passes through its midpoint. The bisector is an important tool in geometry and is used in a variety of applications, including constructing triangles, circles, and finding the circumcenter.
To construct the bisector of a segment, one must first locate the midpoint of the segment. This is done by dividing the length of the segment in half, using a straightedge to connect the two endpoints, and then drawing a perpendicular line through the midpoint. The resulting line is the bisector of the segment.
The bisector has several important properties. First, it is always perpendicular to the segment it bisects. This means that the angle between the bisector and the segment is always 90 degrees. Second, the bisector always passes through the midpoint of the segment. Finally, any point on the bisector is equidistant from the two endpoints of the segment. This means that the bisector can be used to construct other geometric objects that are equidistant from the endpoints of the segment, such as circles.
In summary, the bisector is a line that is perpendicular to a given segment and passes through its midpoint. It is an important tool in geometry and is used in a variety of applications, including constructing triangles, circles, and finding the circumcenter.

Reasoning The measure of ∠1 is 39°. Find the measure of the angle adjacent to ∠1. The figure is not drawn to scale. Use pencil and paper. Explain how you know your answer is reasonable
Assuming that ∠1 and its adjacent angle form a straight line, we know that the sum of the angles on a straight line is 180°. Therefore, the measure of the adjacent angle is 180° - 39° = 141°.
we can also look at the other angles in the figure. From the diagram, we can see that ∠2 and ∠3 are acute angles, which means they are less than 90°. Additionally, we know that the sum of the angles in a triangle is 180°, so ∠2 + ∠3 + ∠4 = 180°.
Since ∠2 and ∠3 are acute, their sum must be less than 180°. Therefore, ∠4 must be an obtuse angle (greater than 90°) in order for the sum to be 180°. This makes sense, as an obtuse angle is required to form a triangle with two acute angles.

One is a six-sided die, and the other is an eight-sided die. We need to find the probability of rolling a sum greater than 12 or a sum that is an odd number after rolling the two dice.It's necessary to know the possible outcomes of the dice game when two dice are rolled. The 6-sided die has possible outcomes {1,2,3,4,5,6}, and the 8-sided die has possible outcomes {1,2,3,4,5,6,7,8}.The possible outcomes for each sum from 2 to 14 are shown below in the following table:The sum of the faces is odd if only one of the dice has an even number. In contrast, the sum of the faces is even if both dice have an even number. The red color represents the sum of the faces, which is an odd number, while the blue color represents the sum of the faces, which is an even number. Now we can easily calculate the total number of sums that are either greater than 12 or an odd number. It is important to note that the sum of 2 and 4 is even, and the sum of 13 and 14 is greater than 12. So the total number of sums that are either greater than 12 or an odd number is: 1 + 4 + 1 + 6 + 8 + 8 + 6 + 1 + 4 + 1 = 40It's also necessary to calculate the total number of possible outcomes when rolling two dice. The number of possible outcomes when rolling two dice is 6 x 8 = 48.We now have everything we need to find the probability of rolling a sum greater than 12 or a sum that is an odd number:Probability = Number of favorable outcomes / Total number of possible outcomes= 40/48 = 5/6Therefore, the probability of rolling a sum greater than 12 or a sum that is an odd number is 5/6.

Janella's basis in her partnership interest was $120,000, including her $150,000 share of partnership debt. At
the end of the current year, the partnership pays off its debts and liquidates. Janella receives a proportionate

partnership = $20,000). How much gain or loss does Janella recognize, and what is her basis in the distributed
property?
Janella recognizes a gain of $36,000 and her basis in the distributed property is $54,000.
Janella's basis in her partnership interest is $120,000, which includes her share of partnership debt. When the partnership pays off its debts and liquidates, Janella receives a proportionate liquidating distribution consisting of $42,000 cash and inventory valued at $24,000 (adjusted basis to the partnership = $20,000).
To calculate Janella's recognized gain or loss, we need to compare her basis in the partnership interest to the fair market value of the distributed assets.
The fair market value of the distributed assets is $42,000 (cash) + $24,000 (inventory) = $66,000.
The amount of the loss is the excess of her basis over the fair market value of the distributed assets, which is $120,000 - $66,000 = $54,000.
To determine Janella's basis in the distributed property, we need to adjust her basis in the partnership interest by the amount of the liquidating distribution she received.
Janella received a total liquidating distribution of $42,000 cash + $24,000 inventory = $66,000. Her share of partnership debt was $150,000, and the partnership paid off all its debts, so she no longer has any debt basis.
Janella's distribution of $66,000 exceeds her adjusted basis of $30,000 by $36,000. She recognizes a gain of $36,000. Therefore, Janella's new basis in the distributed property is $120,000 - $66,000 (liquidating distribution) = $54,000.

? Work out the total surface area of this solid cone. Give your answer rounded to 1 DP. 10m 7m
The total surface area of the solid cone, given the slant height and the radius, would be 374 m².
How to find the surface area of the cone ?To find the surface area of a solid cone, we need to consider both the curved lateral surface and the circular base.
Lateral Surface Area = π x 7 m x 10 m = 70π m²
The base of a cone is a circle with radius r. The area of the base can be calculated using the formula:
Base Area = π x (7 m)² = 49π m²
Total Surface Area = Lateral Surface Area + Base Area = 70π m² + 49π m² = 374 m².

The experimental probability of not selecting a peppermint candy is 77.78%, so the correct option is the third one.
How to find the probability?We want to find the experimental probability of selecting a candy that is not peppermint.
To get this, we need to get the difference between 1 and the probability of getting a peppermint candy, then we will get:
p = 1 - 2/9
p = 7/9
Now we want to express this as a percentage, so we need to multiply this by 100%
p = (7/9)*100%
p = 77.78%
We can see that the experimental probability is the one in the third option.

Solve using the Zero Product Property. Give your answer as a decimal, if necessary. A group of friends tries to keep a small bean bag from touching the ground by kicking it. On one kick, the beanbags height can be modeled by the equation h = −(2t − 3) − 8t(2t − 3), where h is the height of the beanbag in feet and t is the time in seconds. Find the time it takes the beanbag to reach the ground. The time it takes for the beanbag to reach the ground is ___ second(s)
As per the given equation, the beanbag will reach the ground after 1.5 seconds.
To find the time it takes for the beanbag to reach the ground, we need to set h equal to zero, since the beanbag will be on the ground when its height is zero. So we have the equation:
0 = −(2t − 3) − 8t(2t − 3)
We can simplify this equation by factoring out the common factor of (2t − 3):
0 = (2t − 3)(−1 − 8t)
Now we can use the Zero Product Property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero. So we can set each factor equal to zero and solve for t:
2t − 3 = 0 or −1 − 8t = 0
Solving the first equation for t, we get:
2t = 3
t = 3/2
Solving the second equation for t, we get:
−1 − 8t = 0
8t = −1
t = −1/8
However, we need to discard the negative value of t, because time cannot be negative. So the time it takes for the beanbag to reach the ground is t = 3/2 seconds or 1.5 seconds

Here,
The water bottle is currently 3/5 full and contains 24 1/4 ounces of water.
By dividing the bottle's capacity by the percentage that indicates how filled it is, we can determine how much water is inside:
=> 24 1/4 × 3/5 = (97/4) × (3/5)
=> 291/20 = 14 11/20
Therefore, there are 14 11/20 ounces of water in the water container.
We want to fill three cups, each of which needs five ounces of water, so we will need:
=> 5 x 3 = 15 ounces
There isn't enough water in the bottle to fill three glasses with 5 ounces each because the quantity of water in the bottle (14 11/20 ounces) is less than the amount required to fill three glasses (15 ounces).
