Answer:
The correct answer is,
d = 300 feet
Step-by-step explanation:
<u>Points to remember
</u>
The ratio of of corresponding sides of similar triangles are equal.
From the figure we can see two similar triangles.
<u>To find the value of d</u>
It is given that, the ratio of d to 150 ft is the same as the ratio of 40 ft to 20 ft
d/150 = 40/20
d = (150 * 40)/20
d = 300
Therefore the value of d = 300 ft
Horizontal distance x(t) = ut cos θ
x(2) = 102 * 2 * cos 67 = 79.7 ft.
Vertical distance y(t) = ut sin θ - 1/2 gt^2
y(3) = 102 * 2 * sin 67 - 1/2 * 9.8 * (3)^2 = 187.78 - 44.1 = 143.7 ft.
Answer: Choice B) Investment decreases by 3% each month
=====================================================
Explanation:
We won't use the value 2500 at all.
The base of the exponential is 0.97
Set this equal to 1+r and solve for r
1+r = 0.97
r = 0.97-1
r = -0.03
The negative r value indicates we have exponential decay, so the value of the investment decreases by 3% each month.
Let's say you had $100 to start off. This would mean the investment would be worth $97 after one month is up.
