Calculate the angle of a sector of 50° and a radius of 4cm

Answers

Answer 1

Answer: 20π/9 cm²

Step-by-step explanation:

Central angle is given as = 50°

We should note that for a complete circle to be made, it needs 360∘. Therefore, this is 50/360 = 5/36 of the area of a sector.

Area of the sector = 5/36 × πr².

= 5/16 × π × 4²

= 5/36 × π × 16

= 80π/36

= 20π/9 cm²

Step-by-step explanation:

brainliest please?

With fraction exponents, you first raise the base (in this case -216) to the numerator, and then take the root (in this case cube root) of that number.

The y simplified answer would be 1/cuberoot(-216^4)

-216^-4 = 1/2,176,782,336

The cuberoot of that number is 0.000772

Solve the equation for x. Square root of x = 20

Answers

Answer:

x = 16

Step-by-step explanation:

Subtract x from both sides of the equation

[tex]\sqrt{x} = 20 - x[/tex]

To remove the radical on the left side of the equation, square both sides of the equation.

[tex]\sqrt{x}^{2} = (20 - x)^{2}[/tex]

Simplify each side of the equation.

[tex]x = (20 - x)^{2}[/tex]

Solve for x.

[tex]x = 25, 16[/tex]

Exclude the solutions that do not make [tex]x + \sqrt{x} = 20[/tex] true.

x = 16

Answers

The percent is 85 percent since 15 percent is the drink so you subtract 15 from 100 to get 85 percent . The cost is 17 dollars because 20 times 85 percent or 0.85 is 17. So your answers are $17 and 85 percent

The graphs below have the same shape. Complete the equation of the blue
graph. Enter exponents using the caret (-); for example, enter to as x^3. Do
not include "G(x) =" in your answer.

Answers

Answer: g(x) = (x - 1)^3

Step-by-step explanation:

There is a transformation called "horizontal translation"

For an initial function f(x), a horizontal translation of N is written as:

g(x) = f(x - N)

where if N is positive, we have a translation of N units to the right.

If N is negative, we have a translation of N units to the left.

Here, we can see that:

f(x) = x^3, such that when x = 0, f(0) = 0.

And g(x) seems to be a horizontal translation of f(x) (because the graph of g(x) is equidistant to the graph of f(x)), then:

g(x) = (x - N)^3

And we can see that when x = 0, g(0) = 1

Then:

g(0) = (0 - N)^3 = 1

          N^3 = 1

          N = ∛1 = 1

Then the equation for g(x) is:

g(x) = (x - 1)^3

For it to be a line, that means that when x goes up by 1 y goes up by the same thing every time.

7a. from (1, 12) to (2, 8), the x coordinate goes up by 1 and the y coordinate goes down by 4. From (2, 8) to (3, 4) the y coordinate again goes down by 4 when the x coordinate goes up by 1. This pattern continues for the other points, so yes.
