Answer:
The choice two
[tex]5 \sqrt{2} [/tex]
Step-by-step explanation:
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {5}^{2} + {5}^{2} = {c}^{2} \\ 25 + 25 = {c}^{2} \\ 50 = {c}^{2} \\ c = 5 \sqrt{2} [/tex]
This is the change in kinetic energy of a system in which a 16 kg object moving at 25 m/s slows to a velocity of 20 m/s.
The change in kinetic energy of the system is 200 J
Kinetic energy is the energy that an object possesses as a result of its motion.
It is given by:
Kinetic energy = (1/2)m[v - u]²
Where m is the mass of the object, v is the final velocity and u is the initial velocity.
Given that m = 16 kg, v = 20 m/s, u = 25 m/s, hence:
Kinetic energy = (1/2) * 16 * (20 - 25)² = 200 J
The change in kinetic energy of the system is 200 J

expand the following by removing the brackets
-2 (3x + 4)
m ( my -3)
Answer:
-6x-8
m^2y-3m
Step-by-step explanation:
For the first one we simply need to multiply both figures in the bracket by the outer number.
For the second one we do the same thing but as there is an "m" in the bracket and an "m" outside the bracket, this makes a square "^2" which is essentially a figure multiplied by itself.

Answers:[tex]10^2+12^2 = \boldsymbol{244}\\\\14^2 = \boldsymbol{196}\\\\\text{What kind of triangle?} \textbf{ Acute}[/tex]
-------------------------------
Explanation:
The converse of the pythagorean theorem can be used to determine what kind of triangle we're dealing with.
Here are 3 important rules to have in your notes:
[tex]\cdot \text{If } a^2+b^2 > c^2 \text{ then the triangle is } \underline{\text{acute}}\\\\\ \cdot \text{If } a^2+b^2 < c^2 \text{ then the triangle is } \underline{\text{obtuse}}\\\\\cdot \text{If } a^2+b^2 = c^2 \text{ then the triangle is a } \underline{\text{right}} \text{ triangle}\\\\[/tex]
The third rule is probably the most familiar as it's the pythagorean theorem itself.
In this case, we have [tex]a^2+b^2 = 10^2+12^2 = 244[/tex] larger than [tex]c^2 = 14^2 = 196[/tex], which fits the first rule mentioned.
=========================================================
Problem 2 (on the right)
Answers:[tex]8^2+15^2 = \boldsymbol{289}\\\\17^2 = \boldsymbol{289}\\\\\text{What kind of triangle?} \textbf{ Right}[/tex]
-------------------------------
Explanation:
We follow the same idea as problem 1. This time, both [tex]a^2+b^2[/tex] and [tex]c^2[/tex] result in the same value (289). Therefore, [tex]a^2+b^2 = c^2[/tex] is a true equation, and we go for the third rule mentioned earlier. An 8-15-17 right triangle is one of the infinitely many pythagorean triples.

Step-by-step explanation:
The depth of the water at the end of a pier changes periodically along with the movement of tides. On a particular day, low tides occur at 12:00 am and 12:30 pm, with a depth of 2. 5 m, while high tides occur at 6:15 am and 6:45 pm, with a depth of 5. 5 m. Let t = 0 be 12:00 am. Which periodic function, sine or cosine, would be a simpler model for the situation? Explain.
Answer:
A cosine function would be a simpler model for the situation.
The minimum depth (low tide) occurs at t = 0. A reflection of the cosine curve also has a minimum at t = 0.
A sine model would require a phase shift, while a cosine model does not.

Please help everyone!!!!! I will give you brainliest if you answer my question correctly! The average weight of 6 packages is (9m+8) pounds 2 more packages with weights of (12m + 12) pounds and (14m + 12) pounds, are added to the original 6 packages. Find the average weight of the 8 packages.
Answer: 22m + 20
First average the 2 package weights:
(12m+12) + (14m + 12) / 2
(26m + 24) / 2
13m + 12
So the average weight of 2 package is 13m + 12
Now you already know the average of 6 packages that is 9m + 8. So add the 2 package and 6 package average weights.
13m + 12 + 9m + 8
22m + 20
I am not sure unless you or someone else thinks it correct. But thats it, pls forgive me if i am wrong... :(

(03.04 MC)The youth group is going on a trip to the state fair. The trip costs $58. Included in that price is $12 for a concert ticket and the cost of 2 passes, one for the rides and one for the game booths. Each of the passes costs the same price. Write an equation representing the cost of the trip, and determine the price of one pass. Solve your equation by showing your work and steps.
Answer:
58= 2x +12
each pass is 23 dollars
Step-by-step explanation:
let x represent the cost of the passes
58= 2x + 12
solve for x
58-12 = 2x +12 -12
46 = 2x
46/2 =2x/2
23 = x

Answer: Score on a science test, D, Average temperature
Step-by-step explanation:
A: Score on a science test(dependent variables are the "effects" of the independent variable, and number of hour studied results in the score on the science test)
B: D (the input will always remain the same but the output is dependent on the independent variable, so in this case the input is the independent variable)
C:Average temperature( the temperature depends on how far it is from the equator, thus making it the dependent variable in this relationship)

is (-a + b)² = a² - 2ab + b² right or wrong, and why?
Answer:
[tex]\huge\boxed{\sf Right.}[/tex]
Step-by-step explanation:
[tex](-a+b)^2[/tex]
Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².

Find the value of y when m= -2, r = -7 and c= -3.
Answer:
This assume the equation is 35y = mx + c, and that r is meant to be x.
Step-by-step explanation:
35y = mx + c
35y = -2(-7) - 3
35y = 14 - 3
35y = 11
y = (11/35)

1. Timmy wants to buy a scooter and the price was $50. When he goes to the store a second time, he found that price was marked down by 20%. What is the new price?
2. A football is selling for 35% off the original price. The original price was $60. What is the sale price of the football?
The new price of the scooter will be:
= $50 - (20% × $50)
= $50 - $10
= $40
The sale price of the football will be:
= 35% × $60
= $21
