Answer:
She is 90 feet above ground before she begins to descend.
She descends by a rate of 5 feet per second.
Step-by-step explanation:
She is 90 feet above ground before she begins to descend. You can see that by looking at the y value of the highest point of the line, which is just between 80 and 100, which is 90.
We can find the rate of her descending by finding the slope. Remember that the slope formula is (y1-y2)/(x1-x2)
We can find two points on the line and plug the x and y values in. Let's use the points (0, 90) and (16, 10).
We plug the values in:
(90-10)/(0-16)
(80)/-16
-5
The slope is negative, which makes sense, because Aretha is descending and not ascending.
So, she is descending by a rate of 5 feet per second.
I hope this helps you!
Answer:
C
Step-by-step explanation:
The rate of change is measured using
in the closed interval [a, b ]
Here [a, b ] = [35, 45 ]
from the table f(b) = f(45) = 34.1 and f(a) = f(35) = 31.4, hence
rate of change = = = 0.27 → C
Answer:
Step-by-step explanation:
The circumference formula is
C = 2πr. If we are solving the for the radius, and we are using 3.14 for π, we can fill in accordingly:
106.76 = 2(3.14)r and
so
r = 17
Answer:
see below
Step-by-step explanation:
Let x be the original price
x* discount rate = discount
x * 60% = 30
Change to decimal form
x * .60 = 30
Divide each side by .60
x = 30/.60
x =50
The original price was 50 dollars
30:42 is represented as 30/42
The lowest form for that is 5/7. Hope that helped. Good luck
