Answer:
This is one of my specialties so sit back, relax while I work on this for 5 mins :)
Step-by-step explanation:
The formula is a^2 + B^2 = c^2
Sooo
7^2 + 5^2 = c^2
49 + 25 = 74
√74 = √c^2
8.60232526 = c
8.60232526 rounded to the nearest tenth is 8.6
So there you go. Hope it helps!!

Answer:
When someone puts on 20 pounds then, the rate of change of height or the height increases by 0.534 inches.
Step-by-step explanation:
We are given the following equation:
Predicted height = (0.0267 inches per pound)(weight) + 65.2
Let y b the predicted height in inches and x be the weight in pounds.
![y =65.2 + 0.0267x](https://tex.z-dn.net/?f=y%20%3D65.2%20%2B%200.0267x)
Comparing to general form of equation:
![y = mx +c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2Bc)
where m is the slope and c is the y-intercept.
m = 0.0267
Interpretation of slope:
Th slope tells us about the rate of change that is when the weight increases by 1 unit that is 1 pound then, the height increases by 0.0267 inches.
When someone puts on 20 pounds:
![y(x+20)-y(x) =65.2 + 0.0267(x+20) - 65.2 - 0.0267x\\y(x+20)-y(x) = 0.534](https://tex.z-dn.net/?f=y%28x%2B20%29-y%28x%29%20%3D65.2%20%2B%200.0267%28x%2B20%29%20-%2065.2%20-%200.0267x%5C%5Cy%28x%2B20%29-y%28x%29%20%3D%200.534)
Interpretation:
Thus, when someone puts on 20 pounds then, the rate of change of height or the height increases by 0.534 inches.
