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:

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

-7x-2y= -13
x-2y= 11

Solve the question with substitution and show work

Answers

Answer:

x=3,y= -4

Step-by-step explanation:

ii) x-2y=11

x=11+2y-----(i)

Now,

i) -7x-2y= -13

or, -7(11+2y)-2y= -13

or, -77-14y-2y = -13

or -14y-2y = -13+77

or -16y = 64

or y =64÷(-16)

:: y = -4

Again,

(ii) x-2y= 11

or x-2(-4)= 11

or x+8 = 11

or x = 11-8

:: x = 3

if the value of c is negative, you would need zero pairs to model the factorization of the polynomial. the x-tiles on the board determine what the constants are in the factors. the product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. opposite signs on the constants will result in a negative value for c when multiplying the factors.

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A
lacrosse goalie saved 7 of 11 shots. How many additional consecutive saves s must the goalie make to
raise his save percentage to 0.850?

Answers

Answer:

The goalie needs to make 16 more saves in a row.

Step-by-step explanation:

Let n be the number of additional saves needed.

[tex]\frac{7+n}{11+n}\geq 0.85[/tex]

[tex]7+n\geq 0.85(11+n)\\[/tex]

[tex]7+n\geq 9.35+0.85n[/tex]

if θ is an angle in standard position and its terminal side passes through the point (-3,-4), find the exact value of \sin\thetasinθ in simplest radical form.

Answers

Answer:

Here it is given,terminal side passes through the point.
I assume you want to find sinθ?

We know that sinθ = opposite/hypotenuse and that our coordinate point is in Quadrant II. If we construct a right triangle with a height of -4 units and a length of -3 units from right to left, then the side opposite of θ is -3 and the side adjacent to θ is -3. We need to determine the hypotenuse, which can easily be solved with the Pythagorean Theorem:

opp² + adj² = hyp²
-3²+ (-4)² = hyp²
9 + 16 = hyp²
25 = hyp²
5 = hyp

Therefore, sinθ=3/5.

13.5

Explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).

When we plug in the given points, (3,-7) and (5,20) we can start solving.

(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive
