Trying to solve a exponential function question. Evaluate the function when t=5.

If t=5 then all you do is plug that into the function:
h(t)=175(1028)5
You would start by multiplying 1028 by 5 which leaves you with 5140, now plug that into the function.
h(t)=175(5140)
multiply 175 and 5140
h(t)=899500

One type of insect is 0.0052 meter long. What is this length in scientific notation?
____ [38]

You want to move the decimal point to the right until the number is greater than 1 but less than 10.

The number will end up being 5.2

You moved the decimal point 3 times to the right.
So it will be 5.2 x 10^-3. It is negative because you moved it to the right. The exponent would be positive if you moved it to the left
