The answer is 8i.
i = √(-1)
√(-64) = √((-1) * 64)
= √(-1) * √64
= i * √8²
= i * 8
= 8i

Answer:33/32
Step-by-step explanation:
81/4 - 615/32
32•4=128 to get a common denominator
Then whatever you do to the top you do to the bottom.
81•32=2,592
Then you would do
615•4=2,460
Now you have
2,592/128 - 2,460/128
Now you subtract
2,592-2460=132
You keep the denominator
132/128 and then simplify by dividing both numbers by four and you get
33/32
Answer:
f(t) = 5×0.87^t
Step-by-step explanation:
The general form for an exponential function described in this fashion is ...
... f(t) = (starting value) × (1 + (percent change))^t
Here, the "percent change" is -13%, or -0.13.
Then the value (1 + percent change) is (1 + (-0.13)) = 0.87. Putting this and the starting value into the form above, we have ...
... f(t) = 5 × 0.87^t
Answer:
Step-by-step explanation:
h(x) = x² - 2x + 6
h(0) = 0 - 0 + 6 = 6
h(-2) = (-2)² -2*(-2) + 6
= 4 + 4 + 6
= 14
