Answer:
(0.5,0.5)
Step-by-step explanation:
use the midpoint formula x1+x2/2 and y1+y2/2
1) The ball's position is described by:
s(t) = 4.9t² + 450
We want to find the velocity, which is the 1st-order derivative of the displacement function (I assume this is an introductory calculus class)
s'(t) = v(t) = 9.8t
We get this by multiplying 4.9 x 2 and reducing the exponent by 1. Now we simply plug 5 in for t.
v(5) = 9.8* 5
v(5) = 49m/s
2) Our cost function is C(x) = x² - 10,000
To find the average rate of change between these units, we use this formula:
( C(101) - C(100) ) ÷1 .
We find the change in C, and divide by the change in x, which is just one.
C(101) = 101² - 10,000
C(101) = 201
C(100) = 100² - 10,000
C(100= 0
C(101) - C(100) = 201
Average rate of change in cost is 201 dollars/ unit between the two points.
Answer:
0.6825
Explanation:
I'm not fully sure about how to do this, but I believe it might have to do with
the approx. amount of shade, but please take this explanation with a grain of salt as I'm not 100% certain. I am certain about the answer however.
Answer:
25%
Step-by-step explanation:
1. 4.75/19 = .25
2. .25 = 25%
The two triangles are congruent, so corresponding parts of the two triangles are congruent.
GH is corresponding to DE, so GH=DE=17
