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.

Ur answer to ur question would be letter B because the size has changed from its previous form.
2.5 years
~You need to set this problem up in the I=PRT form. This should be your formula then, 450=2400(.075)(t). Then do 2400 times .075 and then times that by t which equals 180t. To get rid of that t then take 450 divided by 180 and you get 2.5. Remember when working with rates put them in decimal form also but your time in years.
I hope this helps you:)
Answer:
It's cheaper to eat out.
Step-by-step explanation:
Cosine = adjacent/hypothenuse
Adjacent = angle between the right angle and C
Adjacent = 21
Hypothenuse = longest side
Hypothenuse = 35
Solution: 21/35
