what s the vertex y=3x^2-18x +30​

Answer:

$39 per square foot.

Step-by-step explanation:

The cylinder has a height of 2 feet and a radius of 5 feet.

The total cost of the metal will be (assuming US dollars) $8572.20.

And we want to determine the cost per square foot.

First, we can find the surface area of the cylinder. The surface area for a cylinder is given by the formula:

[tex]SA=2\pi r^2+2\pi rh[/tex]

Where r is the radius and h is the height.

Since the radius is 5 feet and the height is 2 feet and using 3.14 for π, the surface area is:

[tex]SA=2(3.14)(5)^2+2(3.14)(5)(2) =219.8\text{ feet}^2[/tex]

Therefore, to find the cost of metal per square foot, we can divide the total cost over the amount of surface area. Hence:

[tex]8572.20 / 219.8= \$ 39 \text{ per square foot}[/tex]

So, the metal costs $39 per square foot.

Actually Welcome to the Concept of the areas.

Since we know that, radius = diameter /2

here, => d = 2r ,

hence we use the formula as,

A = πr^2 ,

here option d.) is correct.

Answer:

[tex]3 \sqrt{11} [/tex]

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

[tex] {a}^{2} + {b}^{2} = c {}^{2} [/tex]

where a and b are the legs and c is the hypotenuse l.

Let plug it in

[tex] {a}^{2} + 15 {}^{2} = {18}^{2} [/tex]

[tex] {a }^{2} + 225 = 324[/tex]

[tex] {a}^{2} = 99[/tex]

[tex]a = \sqrt{99} [/tex]

[tex]a = \sqrt{9 \times 11} [/tex]

[tex]a = 3 \sqrt{11} [/tex]

Answer:

A. 5/9

explanation:

The answer is A.

Multiply the fractions.

You can use a calculator online for that. I did and it said 5/9.

When multiplied you get 10/18 and then simplify its 5/9

Answer:

y = -1/2x + 3

Step-by-step explanation:

y - y₁ = m(x - x₁)

⇒ y - 0 = -1/2(x - 6)

⇒ y = -1/2x + 3

Answer:

join my googl met at uns anre dnb

Step-by-step explanation:

Answer:

so angle a is 60 and angle c is 80. you add those together to get 140. you then subtract 140 from 180 and you get 40. lastly you divide 40 by 2 and you get 20 for x.

Answer:

12+28=(4*x B+(4*)

40=4x+-40x

Answer:

The card with the highest interest rate is usually the one that will cause you the most financial pain. The national average interest rate on a credit card is 15.2 percent, so if you bought a $1,000 …

Answer:

Paying off the highest interest rate credit card first makes the most mathematical sense because it will save you more money and allow you to redirect funds to other financial goals faster. Paying off the highest interest rate first is better because this way you get to avoid financial problems and avoid having to pay too much money of interest since the card with the highest interest rate is usually the one that will cause you the most financial pain.

None of these are right

y=$350 because that is her total.

m=$25 because each game cost that.

B=$200 because that's how much the console cost.

$350=$25x+$200

Step-by-step explanation:

The equation to determine the length and width of the rug is 21 = w² + 4w.

A rectangle is a four sided figure with opposite sides are equal .

Area of a rectangle = Length x width

Given that A rectangular rug with an area of 21 square feet.

The rug is 4 feet longer than it is wide.

Let 'l " be the length of the rug and 'w' be the width of the rug

Length is 4 feet longer than its width

l = w + 4

Area is 21 square feet.

Area = l x w

21 = (w + 4)w

21 = w² + 4w

The equation to determine the length and width of the rug is 21 = w² + 4w.

So width is 3 ft

Length = w +4

length = 3+4= 7 feet

Thus Length of the rug is 7 feet

Length of rug = 7 feet

width of the rug = 4 feet
