Answer:
P(t)= 9000(0.4)^t
Step-by-step explanation:
Generally, we have an exponential function as follows;
P(t)= I(1 - r)^t
This case represents a decay ( decrease in value)
from what we have;
I represents the initial value, whereas r is the rate of change
From the question, we have that the change rate is the fraction 3/5
Writing this as a decimal, it is 0.6
substituting this back into the equation, we have;
P(t)= I(1-0.6)^t
P(t)= I(0.4)^t
I in this case is 9,000
So we have it that;
P(t) = 9000(0.4)^t
Answer:
y=154
Step-by-step explanation:
y/7=22
We simplify the equation to the form, which is simple to understand
y/7=22
Simplifying:
+ 0.142857142857y=22
We move all terms containing y to the left and all other terms to the right.
+ 0.142857142857y=+22
We simplify left and right side of the equation.
+ 0.142857142857y=+22
We divide both sides of the equation by 0.142857142857 to get y.
y=154
AnswerThe prime factorization of:2*4 × 5
The answer is 80 on eng
Step-by-step explanation:
C/d + 2 = f/g (subtract 2 from each side)
c/d + 2 - 2 = f/g - 2
c/d = f/g - 2 (multiply d to each side)
c/d*d = d(f/g - 2)
Answer:
= 
(162°)
Step-by-step explanation:
(81°) - 
(81°)
we know that;
(x°) - (x°) = (2x°)
(81°) - (81°) = (2 * 81°)
= (162°)
