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
1 triangle. Every triangle is 180 degrees, and 50 plus 40 plus 90 is 180
Let f(x)= -4x+7 and g(x)= 10x-6. Find f(g(x)).
<em>FYI: f(g(x)) can also be written as (f</em><span><em>○g)(x).
</em>What this really means is to take x and put it through g, then through f.
Since we don't have a specific value for g, we can just put that x value through f,
<em>
</em>g(x) = 10x-6
f(x) = -4x+7
f(g(x)) = -4(g(x))+7
f(g(x)) = -4(10x-6)+7
f(g(x)) = -40x+24+7
f(g(x)) = -40x+31<em>
