How to do the monomials

Cerrena [4.2K]

<u>Given</u>:

The given monomial expression is $\frac{16 y^{8}}{4 y^{2}}$

We need to simplify the given monomial expression.

<u>Simplification:</u>

Let us simplify the given expression.

Dividing the numbers 16 and 4, we get;

$\frac{4 y^{8}}{y^{2}}$

Let us apply the exponent rule $\frac{x^{a}}{x^{b}}=x^{a-b}$ in the above expression.

Thus, we get;

$4 y^{8-2}$

Subtracting the numbers in the numerator of the above expression, we get;

$4 y^{6}$

Thus, the simplified expression is $4 y^{6}$

A grocery store sells and 8 ounce bottle of juice for $1.76 What is the cost of the juice per ounce?

Marat540 [252]

Answer:

$0.22

Step-by-step explanation:

Now we know that 8 ounces total to $1.76. That means that in order to find how much 1 ounce costs, we will end up dividing both sides by 8

8 oz = $1.76

8 oz / 8 = $1.76 / 8

1 oz = $0.22

So, we now know that 1 oz is equal to 22 cents. You can also confirm your answer by multiple 0.22 by 8, and you'll see that you'll get 1.76

What is the area of the figure?

rewona [7]

Answer:

57 square feet

Step-by-step explanation:

Split the boxes into two parts.

One box measuring 11.5 ft long and 3 ft wide. (Box A)

The second box measuring 7.5 ft long and 3 ft wide. (Box B)

Area (figure) = Area of box A + Area of box B

Area of box A

3 × 11.5 = 34.5 ft²

Area of box B

3 × 7.5 = 22.5 ft²

Area of figure = 34.5 + 22.5

Area of figure = 57 ft²

A pumpkin is launched directly upwards at 72 feet per second from a platform 24 feet high. The pumpkins height, h, at time t sec

STALIN [3.7K]

Answer: Maximum height = 105 feet

And, It takes 9/4 seconds to reach that point.

Step-by-step explanation:

Here the given function that shows the height of the pumpkin,

$h(t) = -16t^2 + 72t + 24$ --------(1)

Where t is the time in second.

Differentiating equation (1) with respect to t,

We get, $h'(t) = -32 t + 72$

Again differentiating above equation with respect to t,

We get, $h''(t) = -32$

For maximum or minimum, $h'(t) = 0$

$- 32 t + 72 = 0$

$32 t = 72$

$t = \frac{9}{4}$

At t = 9/4 , h''(t) = Negative value,

Therefore, At t = 9/4 seconds, h(t) is maximum,

And, the maximum value is,

$h(\frac{9}{4} ) = -16(\frac{9}{4})^2 + 72(\frac{9}{4}) + 24$

$h(\frac{9}{4} ) = -16(\frac{81}{16})+ 72(\frac{9}{4}) + 24$

$h(\frac{9}{4} ) = -81 + 162 + 24=105$

Therefore, the maximum height of the pumpkin is 105 feet at 9/4 seconds
