Calculate the height of a right circular cylinder with a surface area of 300 square inches and a radius of 5 inches. a. 2.45 inches c. 8.25 inches b. 4.55 inches d. 3.65 inches

Answers

Answer 1

Answer:

The height of the right circular cylinder is 4.55 inches ⇒ b

Step-by-step explanation:

The formula of the surface area of a right circular cylinder is

S.A = 2πrh + 2πr², where

r is its radiush is its height

∵ The surface area of a right circular cylinder is 300 square inches

S.A = 300 in.²

∵ Its radius is 5 inches

r = 5 in.

∵ π = 3.14

→ Substitute them in the rule above

300 = 2(3.14)(5)(h) + 2(3.14)(5)²

∴ 300 = 31.4h + 157

→ Subtract 157 from both sides

∵ 300 - 157 = 31.4h + 157 - 157

∴ 143 = 31.4h

→ Divide both sides by 31.4

∵ 4.554140127 = h

4.55 = h

The height of the right circular cylinder is 4.55 inches

What is the slope of the line that passes through the points(-4, 0) and (2, 0)?
Write your answer in simplest form.

Answers

Given:

Two points are (-4, 0) and (2, 0).

To find:

The slope of the line that passes through the given points.

Solution:

The line passes through the points (-4, 0) and (2, 0). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{0-0}{2-(-4)}[/tex]

[tex]m=\dfrac{0}{2+4}[/tex]

[tex]m=\dfrac{0}{6}[/tex]

[tex]m=0[/tex]

Therefore, the slope of the line that passes through the points (-4, 0) and (2, 0) is 0.

If f(x) = x4 – 5, then what is the remainder when f(x) is divided by x + 1?

Answers

Answer:

The remainder is: f(-1) = -4

Step-by-step explanation:

We know that when a polynomial function f(x) is divided by x-c, then the remainder is f(c)

Given the function

[tex]f\left(x\right)\:=\:x^4\:-\:5[/tex]

It is stated that the function f(x) is divided by x + 1.

Thus, substituting x = -1 in the function to find the remainder f(-1)

i.e

f(-1) = (-1)⁴ - 5

f(-1) = 1 - 5

f(-1) = -4

Therefore,

The remainder is: f(-1) = -4

what are the smallest values of p and r that satisfy the definitions for parallel lines and perpendicular lines?

Answers

Answer:

p = 2

r = 4

Step-by-step explanation:

If you're doing parallel it needs to be like "side by side." The least you can do is 2 because you'll need at least one other line to be beside the original.

Perpendicular lines are intersecting, so if you intersect them as a plus sign, you'll make at least four right angles.

D 3b. Triangle A has an area of 30cm² and a height of 5. What is the base? ​

Answers

The base of triangle will be 12 cm.

WHAT IS TRIANGLE ? HOW TO FIND ITS AREA ?

A triangle is a three-sided polygon.

The area of a rectangle is commonly known to be b*h, where b is the base and h is the height. Using the formula for a rectangle, we can get the area of a triangle.

A rectangle is split into two congruent triangles by a diagonal. The area of each triangle is equal to half the size of the rectangle.

As a result, the triangle's area A may be calculated using the equation A=1/2*b*h, where b denotes the triangle's base and h its height.

CALCULATION

AREA OF TRIANGLE = 1/2*b*h

base = area of triangle * 2 / h

         = 30 * 2 / 5

         = 12 cm.

i suck at math please help lol

Answers

Answer:

1

Step-by-step explanation:

since the 2 functions equal each other:

-2x + 3 = 4x - 9

add -2x to both sides

3 = 6x - 9

add 9 to both sides

12 = 6x

divide by 6

2 = x

you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway

-2(2) + 3

-4 + 3

-1 = y

Now we'll find x + y, input them and it's 2 + (-1), which is 1
