Hint:

Simply put the values and get the answer.

The correct answer is: 24

Explanation:

We have given an expression $h left parenthesis x right parenthesis equals 2 to the power of x$ .

We have to find the value of $h left parenthesis 5 right parenthesis minus h left parenthesis 3 right parenthesis$ .

We will first find the value of h(5) and h(3) individually by putting respective value of x .

Then by subtractingwe will get the value of h(4) - h(3).

Step 1 of 1:
The given expression is $h left parenthesis x right parenthesis equals 2 to the power of x$ .
The value of h(5) will be
$table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell h left parenthesis 5 right parenthesis equals 2 to the power of 5 end cell row cell h left parenthesis 5 right parenthesis equals 32 end cell end table$
Then, the value of (3)
$table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell h left parenthesis 3 right parenthesis equals 2 cubed end cell row cell h left parenthesis 3 right parenthesis equals 8 end cell end table$
Now the value of h(5) - h(3) will be
$equals h left parenthesis 5 right parenthesis minus h left parenthesis 3 right parenthesis$
= 32 - 8
= 24
Hence, Option C is correct.

Of the following, which is closest to the ratio of the total number of insects in all three colonies in week 8 to the total number of insects at the time of initial treatment?

Three colonies of insects were each treated with a different pesticide over an 8-week period to test the effectiveness of the three pesticides. Colonies A, B, and C were treated with Pesticides A,B , and C, respectively. Each pesticide was applied every 2 weeks to one of the three colonies over the 8-week period. The bar graph above shows the insect counts for each of the three colonies 0,2,4,6, , and 8 weeks after the initial treatment.
