A diver is standing on a platform 25 feet above the pool. He jumps from the platform at an initial velocity of 10 ft/s. Use the formula h(t)=-16t^2+vt+s where his height above the water at time t seconds, v is the starting upward velocity, and s is his starting point to write an equation to model the dive
Answer:
(one thing to notice, the units of the 16 in the height equation should be ft/s^2, because this is an acceleration)
We know that:
v is the initial vertical velocity, and we know that it is 10ft/s
then:
v = 10ft/s.
s is the initial position, and we know that he starts on a platform 25ft above the pool, then if we define the pool as the 0 in the vertical axis, we have:
s = 25ft
Now we can write the height as:
h(t) = (-16ft/s^2)*t^2 + (10ft/s)*t + 25ft.
Now with this equation, we can find the time it takes for the diver to hit the pool.
Remember that we defined the pool as the 0 in the vertical axis, then when h(t) = 0ft the diver will enter in the pool.
With that, we can find the value of t = time, that it takes for the diver to enter the pool.
h(t) = 0 ft = (-16ft/s^2)*t^2 + (10ft/s)*t + 25ft.
Now we can solve this with the Bhaskara equation:
[tex]t = \frac{-10m/s +. \sqrt{(10m/s)^2 - 4*(25ft)*(-16ft/s^2)} }{-16ft/s^2*2} = \frac{-10ft/s +- 41.23ft/s}{-32ft/s^2}[/tex]
We will have two solutions:
t = ((-10 + 41.23)/-32) s = -0.96s
t = (-10 - 41.23)/-32) s = 1.6 s
The negative has no physical sense, so we can discard that option.
This means that the only correct option is 1.6 seconds, then the time that it takes for the diver to enter the pool after he jumps is 1.6 seconds.

Answer:
Gold square = 4
Blue triangle = 3
Step-by-step explanation:
Red hexagon = 6, and there are 4 red hexagons. So the total is 24.
Therefore, the total on the other side must also be 24.
That means the 4 blue triangles add up to 12, and the 3 gold squares add up to 12.
So each blue triangle is 3, and each gold square is 4.
Tom needs 9/10 pints of glue for his art project. He has 7/10 pints of glue. How much more glue does he need? write in simplest form.
Answer:
7/10-5/10= 2/10≈ 1/5
Step-by-step explanation:
hope this is right and i hoped this helped
Answer:
1/5 pint
Step-by-step explanation:
given:
Amount of Glue needed = 9/10 pints
Amount of Glue available = 7/10 pints
Amount of extra glue needed = Amount of glue needed - Amount of Glue Available
= 9/10 - 7/10
= (9-7)/10
= 2/10 (simplify by dividing both numerator and denominator by 2)
= 1/5 pint
a and b are positive numbers.
a is inversely proportional to b.
when a=4,b=36
find value of a when b=a
Answer:
a = 12
Step-by-step explanation:
Given that a is inversely proportional to b then the equation relating them is
a = [tex]\frac{k}{b}[/tex] ← k is the comstant of proportion
To find k use the condition when a = 4, b = 36, then
4 = [tex]\frac{k}{36}[/tex] ( multiply both sides by 36 )
144 = k
a = [tex]\frac{144}{b}[/tex] ← equation of proportion
When b = a , then
a = [tex]\frac{144}{a}[/tex] ( multiply both sides by a )
a² = 144 ( take square root of both sides )
a = ± [tex]\sqrt{144}[/tex] = ± 12
However a is a positive number, thus a = 12
Using the following graph, determine the slope of the line,
The slope of the line is
Answer:
-2
Step-by-step explanation:
Just choose any two points and calculate the slope. The way to calculate the slope between two points (x1, y1) and (x2, y2) is (y2-y1)/(x2-x1)
What is equivalent to 6/9
Answer:
Answer: 2/3
Step-by-step explanation:
6 and 9 are divisible by 3 so if you divide the numerator and denominator by 3 you obtain the equivalent fraction 2/3.
You can also multiply the numerator and denominator by the same amount to obtain an equivalent fraction.

44 = 2(3x - 5)
Answer:
x = 9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
44 = 2(3x − 5)
44 = (2)(3x) + (2)(−5) (Distribute)
44 = 6x + −10
44 = 6x − 10
Step 2: Flip the equation.
6x − 10 = 44
Step 3: Add 10 to both sides.
6x − 10 + 10 = 44 + 10
6x = 54
Step 4: Divide both sides by 6.
[tex]\frac{6x}{6} = \frac{54}{6}[/tex]
x = 9

The distance between two towns is 130 kilometers. There are approximately 8 kilometers in 5 miles.
Which measurement is closest to the number of miles between the two towns?
Please Give A Good Answer Ill Give Brainest And Extra Points
Answer: 81 miles
Step-by-step explanation:
From the question, we are informed that the distance between two towns is 130 kilometers and that there are approximately 8 kilometers in 5 miles.
The measurement that is closest to the number of miles between the two towns goes thus:
Firstly, we need to divide 130 kilometers by 8 kilometers. This will be:
= 130/8
= 16.25
Then, we multiply 16.25 by 5 to get the number of miles between the two towns. This will be:
= 16.25 × 5 miles
= 81.25 miles
= 81 miles
