Enter the value of the exponential expression 5 to the power 0

1

Step-by-step explanation:

5^0 = 1.  Any base to the power 0 returns the value 1.

0

Step-by-step explanation:

any number n to the power of 0 is 0 because it's n times 0

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

m∠a is 90°

m∠b is 40°
