Step-by-step explanation:
P(t) = 8 − 2√(2t + 4)
The x-intercept(s) is where t = 0.
P(0) = 8 − 2√(0 + 4)
P(0) = 8 − 4
P(0) = 4
The y-intercept(s) is where P = 0.
0 = 8 − 2√(2t + 4)
2√(2t + 4) = 8
√(2t + 4) = 4
2t + 4 = 16
2t = 12
t = 6
So the intercepts are at (0, 4) and (6, 0).
The easiest way to tell if the function is increasing or decreasing is to graph it. Otherwise, we have to either use calculus to find the derivative, or assume the function is constantly increasing/decreasing and use limits.
lim(t→∞) P(t) = -∞
The function is decreasing.
Answer:
21
Step-by-step explanation:
The ratio is 5x To 3x so the difference is 2x
14/2 =7 So x=7
so 3(7)=

Answer:
A. Divide by 100
C. Move the decimal point two places to the left
Step-by-step explanation:
To write a percent as a decimal, divide by 100 or move the decimal point two places to the left.
To solve this we will first see how many hats Susan has left when she lets her friends borrow the hats.
45 - 3 = 42
42 - 2 = 40
So, Susan has 40 hats left after her friends borrowed some. Now lets divide to see how many hats will go in 1 cupboard.
40 ÷ 20 = 2
2 hats in each cupboard.
CHECK OUR WORK:-
20 × 2 = 40.
We were RIGHT!!!
So, after Susan's friends borrow some of her hats she can put 2 hats in each cupboard.
