Find the zero of f(x) = x^5-12x^2+32x

1 answer:

8 0

The zeroes of f(x) = x^5-12x^2+32x can be found by factoring,

f(x) = x^5-12x^2+32x=(x-8)(x-4)

By the zero product theorem, (x-8)=0 or (x-4)=0 which means
x=8 or x=4.

So the zeroes of f(x) are S={4,8}

the length of a sandbox is three feet longer than it’s width. Write the expression that would represent the area of the sandbox.

Rashid [163]

Part A : D.)

Part B : Length of the sandbox is 10 feet.

Step-by-step explanation:

Given,

Perimeter = 29 ft

We need to find the equation for the perimeter and also the length of the sandbox.

Solution,

Let the width of the sandbox be 'w'.

Now as per question said;

The length of the sandbox is 1 foot longer than twice the width of the sandbox.

So we can say that;

Length =

Now we know that the perimeter is equal to the sum of twice of length and width.

framing in equation form, we get;

Perimeter =

we have given the perimeter, so on substituting the value, we get;

Hence The equation used to find the width is .

Now we solve for 'w'.

Applying distributive property, we get;

Subtracting both side by '2' we get

Dividing both side by 6 we get;

Width of the sandbox = 4.5 ft

Length of the sandbox =

Hence Length of the sandbox is 10 feet.

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level, how long will

navik [9.2K]

Answer

Find out the how long will it take the submarine to descend to the ocean floor

To proof

Formula

$r = \frac{d}{t}$

where d = distance traveled (or descended),

r = rate of travel , t = time

As given

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level .

put all the values in the above formula

$2.6 = \frac{6.24}{t}$

$t = \frac{6.24}{2.6}$

t = 2.4 hour

it take 2.4 hours the submarine to descend to the ocean floor .

Hence proved
