A circle has a diameter of 12 inches. A central angle of the circle intercepts an arc with a length of 3 inches. What is the radian measure of this central angle?
A.2
B.4
C.0.25
D.0.5

9514 1404 393

Answer:

  30.3 in

Step-by-step explanation:

The applicable relation between angle (θ), radius (r), and arc length (s) is ...

  s = rθ . . . . . . where θ is in radians

We have ...

  75 in = x(142(π/180))

Solving for x, we get ...

  x = (75 in)(180/142)/π ≈ 30.262 in

The radius of the circle is about 30.3 inches.

Step-by-step explanation:

Answer:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = Prt (Where p=principle,r=rate,t=time)

I = p*0.08*1=0.08p

Step-by-step explanation:

Bo should multiply his current amount by 1.08 to get the complete balance in one step.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given that Bo invests money in an account paying a simple interest of 8% per year.

To find the total balance in a year, you can use the formula:

balance after 1 year = balance × (1 + (interest rate/100))

In this case, the interest rate is 8%, so you can use the formula like this:

balance after 1 year = balance × (1 + (8/100))

This simplifies to:

balance after 1 year = balance × 1.08

Therefore, to find the total balance in one step, Bo should multiply his current balance by 1.08.

Answer:

15/100 x 35 = $5.25

Of means multiplication

Always consider a percent as a fraction but it has to be out of 100.

A way to remember that is that the word "cent" means 100. So you multiply the two numbers (divide at the end 21/4 = 5.25)

what is this for

Step-by-step explanation:

A cuboid with side lengths x, x and h has a surface area of

S=2x2+4xh.

We know that the total surface area should be 150cm2, so

150⟹150−2x2⟹h=2x2+4xh=4xh=75−x22x.

Answer:

Nuclear Fusion is the cleanest.

Step-by-step explanation:

The following advantages make fusion worth pursuing. Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass).

Answer:

r = 5√6 feets

Step-by-step explanation:

Angle = 60°

Area of a sector = ∅/360 × πr²

Area = 25πfeet²

25π = 60/360 × πr²

25π = ⅙ × πr²

25π × 6 = πr²

150π = πr²

π cancelled off......

r² = 150

r = √150

r = √(25 × 6)

r = 5√6 feets

OR

r = 12.2474

r ≈ 12.25 feets

Answer:

Answer:

Domain: (-3,1]

Range:  [-4,0]

x-intercepts: -3, 0

y-intercepts: 0

Answer:

R =  [-4,0]       X = -3, 0     Y = 0

Step-by-step explanation:

We already know the domain.

Range : [-4,0]   Since the line doesn't go beyond 0.

x-intercept : -3, 0

y-intercept : 0

This is because

tan(angle) = opposite/adjacent

For the reference angle 38, we have 10 as the opposite side and x as the adjacent side.

Therefore, tan(38) = opposite/adjacent = 10/x

Side note: if you solve for x, you should get roughly x = 12.799

Step-by-step explanation:

Answer:

y = 5x - 8

Step-by-step explanation:

The linear equation in slope intercept form :

y = mx + c

m = slope ; c = intercept

m = Rise / Run = (y2 - y1) / (x2 - x 1)

Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20

Run = (x2 - x1) = (4 - 0) = 4

Slope, m = Rise / Run = 20 /4 = 5

Hence,

y = 5x + c

For the points ; y = 12 ; x = 4 ; we could obtain c

12 = 5(4) + c

12 = 20 + c

12 - 20 = c

-8 = c

The equation becomes :

y = 5x - 8
