Answer: If we define 2:00pm as our 0 in time; then:
at t= 0. the velocity is 30 mi/h.
then at t = 10m (or 1/6 hours) the velocity is 50mi/h
Then, if we think in the "mean acceleration" as the slope between the two velocities, we can find the slope as:
a= (y2 - y1)/(x2 - x1) = (50 mi/h - 30 mi/h)/(1/6h - 0h) = 20*6mi/(h*h) = 120mi/![h^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D)
Now, this is the slope of the mean acceleration between t= 0h and t = 1/6h, then we can use the mean value theorem; who says that if F is a differentiable function on the interval (a,b), then exist at least one point c between a and b where F'(c) = (F(b) - F(a))/(b - a)
So if v is differentiable, then there is a time T between 0h and 1/6h where v(T) = 120mi/![h^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D)
Answer:
$4811
Step-by-step explanation:
Initial price = 35,000
18% decrease anually = 18/100 = -0.18
after 10 years
substitute these values in the formula shown in below figure
A = 35000 * ( 1 + -0.18/1 ) ^10
= 35000 * 0.82^10
= 4,810.681
= $4811
2a+3
Step-by-step explanation:
Answer:
a = 19
Step-by-step explanation:
If the rate of change is -8, subtract 8 from your y value of 27. And if 19 is correct, you should be able to subtract 8, and get 11 as the next number in the function, which you do, so 19 is the value of a.
It's a parallelogram so if one angle is 90 degrees they all will be because of transverse angles and all that good stuff.
So we're given the diagonal of a rectangle and one side and we're asked to find the other. The diagonal of a rectangle is the hypotenuse of the right triangle whose legs are the sides of the rectangle. So this is a Pythagorean Theorem question in disguise:
![AB^2 + AD^2 = BD^2](https://tex.z-dn.net/?f=AB%5E2%20%2B%20AD%5E2%20%3D%20BD%5E2)
![AD^2 = BD^2 - AB^2](https://tex.z-dn.net/?f=AD%5E2%20%3D%20BD%5E2%20-%20AB%5E2)
![AD = \sqrt{ BD^2 - AB^2 }](https://tex.z-dn.net/?f=AD%20%3D%20%5Csqrt%7B%20BD%5E2%20-%20AB%5E2%20%7D)
![AD = \sqrt{149^2 - 51^2} = \sqrt{19400} = 140](https://tex.z-dn.net/?f=%20AD%20%3D%20%5Csqrt%7B149%5E2%20-%2051%5E2%7D%20%3D%20%5Csqrt%7B19400%7D%20%3D%20140%20)
Answer: 140 cm
I don't recall seeing this Pythagorean Triple before.
