Answer:
D -- the last one
Step-by-step explanation:
The formula tells you what to do.
t = 3
A0 = 25
A(t) = ?
A(3) = 25 * (1/2)^3
A(t) = 25 * 1/8
A(t) = 25/8
A(t) = 3.125
Answer: The answer is 2,4. May I have the brainiest? pls I only need one more.
Answer:
4 gallons
Step-by-step explanation:
We can write a ratio to solve
95 miles 76 miles
----------------- = -------------
5 gallons x gallons
Using cross products
95 * x = 5 * 76
Divide each side by 95
x = 5 * 76 / 85
x =4
Answer:
Step-by-step explanation:
Given:
(y/y - 4) - (4/y + 4) = 32/y^2 - 16
Note y^2 - 16 = (y - 4 ) × (y + 4)
Multiplying the equation; both sides by y^2 - 16,
y (y + 4) - (4(y - 4)) = 32
y^2 + 4y - 4y + 16 = 32
y^2 = 32 - 16
Squaring both sides,
y = sqrt(16)
= 4
