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
4*5=20
8*(7-4)=24
20+24=44
The trick is to make the figure into two
Answer:
Polynomials in one variable are algebraic expressions that consist of terms in the form axn a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial.

Answer:
Point in Quadrant I
Step-by-step explanation:
the lines will overlap in quadrant I (the positive quadrant)
Slope = -3
y2 = k
y1 = 5
x2 = 4
x1 = 2
Slope = <span> y2- y1 / x2- x1
-3 = k-5 / 4-2
-3 = k-5 / 2
k-5 = -3 * 2 = -6
k = -6+ 5
k = -1
Therefore, the value of k is -1 .</span>
