Answer:
B:-1
Step-by-step explanation:
Just took test 2021
Answer:
2
Step-by-step explanation:
the rate of change is measured as
in the closed interval [ a, b ]
here [a, b ] = [- 4, 1 ]
f(b) = f(1) = 2 + 4 = 6
f(a) = f(- 4) = - 8 + 4 = - 4
average rate of change = 
= 
= 2
84 x .70 = $58.80
Or if you want to do it the long way you can calculate the actual discount (your savings from this purchase first then subtract it from the original price of $84. It`s just easier to figure out what is left (which is 70% of $84).
Answer:
LEts start with 10^1
If we have positive exponent then we add zeros
10^1= 10
(Put 2 zeros because exponent is 2)
(Put 3 zeros because exponent is 3)
(Put 4 zeros because exponent is 4)
(Put 5 zeros because exponent is 5)
For negative exponent , we make a fraction . we put 1 at the top always and number as the bottom
(Put 1 zero at the bottom because exponent is -1)
(Put 2 zeros at the bottom because exponent is -2)
(Put 3 zeros at the bottom because exponent is -3)
