Answer 1

Answer:

Answer:

Step-by-step explanation:

since the school recorded is in two minutes, they wrote 420 words, and Katie in 5 minutes wrote 600 words, if you put the average to the person who wrote 420 words in 2 minutes to-

in every too minutes they write 420 words.

so in four minutes they would of typed 840 words, which is more words than Katie in less minutes.

If h(x) = 6 – x, what is the value of (hOh) (10)

Answers

h(h(10))---> h(-4)---->10 ......hOh(10)=10

Final answer:

The value of (hOh)(10) when h(x) = 6 - x is found by firstly evaluating h(10) to get -4, and then evaluating h(-4) to get 10. So the answer to the question is 10.

Explanation:

The question is asking for the value of the function (hOh)(10) when h(x) = 6 - x. This notation represents the composition of the function h with itself evaluated at x = 10. So we first apply the function h to the input 10, and then apply h again to the resulting output. In mathematical terms, this operation is written as (h∘h)(10).

First, we find the value of h(10), by plugging x = 10 into the function h(x) = 6 - x. This gives h(10) = 6 - 10 = -4.

Next, we find the value of h(h(10)), by plugging the output of the previous step (-4) into the function as the new input. This gives h(h(10)) = h(-4) = 6 - (-4) = 10.

So, the value of (hOh)(10) is 10.
