Answer:

h'(1)=0

Step-by-step explanation:

We use the definition of the derivative of a quotient:

If $h(x)=\frac{f(x)}{g(x)}$ , then:

$h'(x)=\frac{f'(x)*g(x)-f(x)*g'(x)}{(g(x))^2}$

Since in our case we want the derivative of $h(x)$ at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

$h'(1)=\frac{f'(1)*g(1)-f(1)*g'(1)}{(g(1))^2}$

which, by replacing with the given numerical values:

$f(1) =4\\g(1)=3\\f'(1)=-4\\g'(1)=-3$

becomes:

$h'(1)=\frac{f'(1)*g(1)-f(1)*g'(1)}{(g(1))^2}=\\=\frac{-4*3-4*(-3)}{(3)^2}=\frac{-12+12}{9} =\frac{0}{9} =0$

What is the square root of this problem?—-

musickatia [10]

<h2>Answer</h2>

The answer to this question is 0.9

<h2>Explanation</h2>

We know that

sequre of 9 is equal to 81 as $9^2 = 81$

Then sequre of 0.9 will be

$0.9^2 = 0.81$

So,

b = $\sqrt{ 0.81}$

b = $\sqrt{ 0.9^2}$

Exponent and square root cancel out each other

So, the answer is 0.9.

HELP PLEASE :/ math is not my bff

gtnhenbr [62]

1. None of the answer choices are correct, because the length that were to go with those numbers don't fit. The answer is D.

2. One coffee cost $4 and a latte would cost $2.50, because the other prices for a cup of coffee would exceed the price of the total of two coffees plus one latte and three coffees plus two lattes. The answer is A: $4.00.

3. This one has to be A, because you're finding how many nickels and dimes there are together if there are 24 coins. A nickel is 5 cents each and a dime is 10 cents each. The total of them combined is $1.85. The answer is A.
