A cone has a circular base with a diameter of 18 inches. The height of the cone is 40 inches. What is the approximate lateral ar
aliya0001 [1]

The approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches

<h3>What is the lateral area of cone?</h3>

Lateral area of the cone is the area bounded by the surface of the cone, and this Lateral area of the cone can be found out using the following formula.

A=\pi r\sqrt{h^2+r^2}

here. (<em>h</em>) is the height of the cone and (<em>r</em>) is the radius of the cone.

A cone has a circular base with a diameter of 18 inches. The height of the cone is 40 inches.

Put these values in the above formula as,

A=(3.14) (9)\sqrt{40^2+9^2}\\A\approx1159\rm \; in^2

Hence, the approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches

Ella swims four times a week at her club's pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps
ZanzabumX [31]

Answer:

Equation for the problem

3x + 15 = 51 laps

Hence

She swims on

Monday: 12 laps

Wednesday : 12 laps

Friday = 12 laps

Step-by-step explanation:

Ella swims four times a week at her club's pool.

We are told that:

She swims the same number of laps on Monday, Wednesday, and Friday.

Hence, the number rod times that she swims on Monday, Wednesday and Friday is represented by x

Also, she swims 15 laps on Saturday. She swims a total of 51 laps each week. Equation for the problem

= x + x + x + 15 = 51 laps

3x + 15 = 51 laps

Hence

3x = 51 - 15

3x = 36

x = 36/3

x = 12 laps

Therefore, She swims on:

Monday: 12 laps

Wednesday : 12 laps

Friday = 12 laps

If f(x) = x/2 -2 and g(x) = 2x^2 + x - 3, find (f+g) (x) A. 2x^2+3/2x +1 B. 2x^2+3/2x-5 C. x^2 - 6 D. 2X^2- x/2 + 1
Fed [463]

Answer:

              \bold{(f+g)(x)=2x^2+\frac32x-5}

Step-by-step explanation:

f(x) =\frac x2-2\quad and\quad g(x) = 2x^2 + x - 3\\\\(f+g)(x)=f(x)+g(x)\\\\(f+g)(x)=\frac12x-2+2x^2+x-3\\\\(f+g)(x)=2x^2+\frac32x-5
