Answer:

<em>Option D.</em>

Step-by-step explanation:

To raise a product to an exponent, you must raise each factor of the product to the exponent. The product being raised to an exponent is 4z^8. This product is being raised to the -3 power. To raise it to the -3 power, you must raise each factor of the product to the -3 power.

(4z^8)^-3 = 4^-3 * (z^8)^-3.

4 must be raised to the -3 power, and z^8 must also be raised to the -3 power.

The weight distribution of a vehicle specifies that the front wheels carry 55% of the weight. If a certain vehicle weighs 3890 l
mario62 [17]

Answer:

2,139.5 lbs

Step-by-step explanation:

A certain vehicle weighs 3,890 lbs.

The front wheels carry 55% of the weight.

Then,

3,890 lbs - 100%

x lbs - 55%

Write a proportion:

\dfrac{3,890}{x}=\dfrac{100}{55}

Cross multiply:

100x=55\cdot 3,890

100x=213,950\\ \\x=2,139.5

A square garden has a diagonal of 12m. What is the perimeter of the garden? Express in simplest radical form.
FromTheMoon [43]

Answer:

24√2

Step-by-step explanation:

Let the side of the square be x

If the diagonal is 12m (hypotenuse), then;

x^2 + x^2 = 12^2

2x^2 = 144

x^2 = 144/2

x^2 = 72

x = √72

x = √36*2

x = 6√2

Perimeter of the square garden = 4x

Perimeter of the square garden = 4(6√2)

Perimeter of the square garden = 24√2

What about this one ?
salantis [7]
The options are given in factored form.

If a function is zero at x=3, this means x=3 is a root of the equation. x = 3 can also be written as x - 3 = 0

So, if x = 3 is a root of the equation, x - 3 will be a factor of the function. From the given options we can see only Option C contains x - 3 as its factor. Substitute x = 3 in option C and the function value will be zero.

So, the correct answer is option C
