Mathematics

The domain of a function is the set of values that are used as the x-coordinate.

As the parabola continues to go up and widen, all real numbers will be used as x-coordinates, so the domain is all real numbers.

Alex and Ben were given a total of £240 They shared the money in the ratio 5:7
AfilCa [17]

Answer:

Ben received: £140

Step-by-step explanation:

Total amount = £240

Given ratio: 5:7

It means £240 is divided into 12 parts

So 1 part will be equal to:   £240/12

1 part = £20

Now given ratio is:

5:7

Multiplying each share with £20

5*(£20) : 7* (£20)

£100: £140

So according to ratio amounts:

Alex received:  £100

Ben received: £140

I hope it will help you!

Find the total surface area.
Ede4ka [16]

Hey love! <3

Answer:

The right answer is A = 49.6 π ft^2

Step-by-step explanation:

<em><u>(Let pi = 3.1415926535898)</u></em>

<em>The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2</em>

<em>So if r = 4 ft</em>

<em>and h = 2.2 ft</em>

<em>A= 2π(4)(2.2)+2π(4)^2</em>

<em>Once we've plugged in our formulas our final surface area is A =</em><em> 49.6 π ft2</em>

<em />

<em>Hope this helped you calculate the surface area! ◃┆◉◡◉┆▷ Sincerely, Kelsey from Brainly.</em>

5 points<br> Write the polynomial 5x + 2x3 + 8x2<br> 7 in standard form.
artcher [175]

Find the GCF, then factor it out. Finally, simplify each term in the parentheses.

5x + 2x3 + 8x2

x(\frac{5x}{x}+\frac{2x^3}{x}+\frac{8x^2}{x} )

x(5+2x^2+8x)
