four less than the quotient of a number cubed and seven, increased by three

4-\frac{x^3}{7}+3

five times the difference of a number squared and six

5(x^2-6)

nine more than the quotient of six and a number cubed, decreased by four

9+\frac{6}{x^3}-4

twice the difference of nine and a number squared

Youyou havehave aa seriousserious doubledouble pastepaste problemproblem

the equation of the line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given

the point is (5,-3) and the slope is 23 (or it could be 2/3)
x1=5
y1=-3
y-(-3)=23(x-5)
y+3=23(x-5) is answer

VladimirAG [237]
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

A cylinder shaped water pitcher has a radius of 5 inches and a height of 12.5 inches. Find the surface area of the pitcher.

<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>

<h3>Given:-</h3>

\bullet Radius (r) of a cylinder shaped water pitcher = 5 inches.

\bullet Height (h) of a cylinder shaped water pitcher = 12.5 inches.

<h3>To Find:-</h3>

The surface area of the pitcher.

<h2>Solution:-</h2>

We know,

Formula of Surface area of a cylinder is 2πr(r + h) sq. units.

So,

Surface area of the pitcher = 2 × 3.14 × 5(5 + 12.5)

Surface area of the pitcher = 31.4 × 17.5

Surface area of the pitcher = 549.5 in²

\therefore The surface area of the pitcher is <u>5</u><u>4</u><u>9</u><u>.</u><u>5</u><u> </u><u>i</u><u>n</u><u>²</u>.

Hence, the option (C) <u>5</u><u>4</u><u>9</u><u>.</u><u>5</u><u> </u><u>i</u><u>n</u><u>²</u> is correct. [Answer]
