First you need to find the area of the deck by multiplying 42 and 28 together, which gives you 1176ft². If one gallon covers 350ft², you do 1176 ÷ 350 = 3.36 gallons. I hope this helps!

Which expression is equivalent to
lutik1710 [3]

Answer:

\frac{\sqrt[4]{3x^2} }{2y}

Step-by-step explanation:

We can simplify the expression under the root first.

Remember to use  \frac{a^x}{a^y}=a^{x-y}

Thus, we have:

\sqrt[4]{\frac{24x^{6}y}{128x^{4}y^{5}}} \\=\sqrt[4]{\frac{3x^{2}}{16y^{4}}}

We know 4th root can be written as "to the power 1/4th". Then we can use the property  (ab)^{x}=a^x b^x

<em>So we have:</em>

<em>\sqrt[4]{\frac{3x^{2}}{16y^{4}}} \\=(\frac{3x^{2}}{16y^{4}})^{\frac{1}{4}}\\=\frac{3^{\frac{1}{4}}x^{\frac{1}{2}}}{2y}\\=\frac{\sqrt[4]{3x^2} }{2y}</em>

<em />

<em>Option D is right.</em>

You are choosing between two mugs. One has a base that is 5.5 inches in diameter and a height of 3 inches. The other has a base
professor190 [17]

We should choose mug 1 having volume of  71.24 inch³ ,with diameter 5.5 inches and height 3 inches holds the most !

<u>Step-by-step explanation:</u>

We have 2 mugs, One has a base that is 5.5 inches in diameter and a height of 3 inches. The other has a base of 4.5 inches in diameter and a height of 4 inches. Basically, mugs are cylinders so we will consider 2 cylinders .

To find which one holds the most we are supposed to find volume of both ,the one with maximum volume holds the most.

<u>Part 1: </u>

volume of cylinder 1 (V_{1})= πr₁²h₁ ,

r₁ = radius of cylinder ⇒ \frac{\text {diameter}}{2}=\frac{5.5}{2}=2.75 \text { inches }

h₁ = height of cylinder ⇒  3 inches

∴ V_{1} = πr₁²h₁

⇒ 3.14×( 2.75 )²×3 ⇒ 71.24 inch³

<u>Part 2:</u>

volume of cylinder 2 ( V_{2} )= πr₂²h₂

r₂ = radius of cylinder ⇒ \frac{\text {diameter}}{2}=\frac{4.5}{2}=2.25 \text { inches }

h₂ = height of cylinder ⇒  4 inches

∴ V_{2} = πr₂²h₂

⇒ 3.14×( 2.25 )²×4 ⇒ 63.59 inch³

∵ V_{1} ( 71.24 inch³ ) > V_{2} ( 63.59 inch³ ), mug 1 with diameter 5.5 inches and height 3 inches holds the most.

Step-by-step explanation:

Parts of the question are missing.

y = a(x-h)² + k is a vertical parabola.

If a is positive, the parabola opens upwards.

If a is negative, the parabola opens downwards.

The vertex is at (h, k)
