Answer:

3/4 of the area of the circle is of 48\pi squared units.

Step-by-step explanation:

Equation of a circle:

The equation of a circle has the following format:

(x - x_0)^2 + (y - y_0)^2 = r^2

In which the center is (x_0,y_0) and r is the radius.

Area of a circle:

The area of a circle of radius r is given by:

A = \pi r^2

Circle (x+2)² + (y-5)² = 64

Comparing with the standard equation, we have that:

r^2 = 64

Area of the circle:

A = \pi r^2 = 64\pi

What is 3/4 of its area?

\frac{3A}{4} = \frac{3*64\pi}{4} = 3*16\pi = 48\pi

3/4 of the area of the circle is of 48\pi squared units.

How do you know what 0 to place the decimal point at for scientific notation? Please explain in detail.
laiz [17]

To convert a decimal into scientific notation, move the decimal point until you get to the left of the first non-zero integer. The number of places the decimal point moves is the power of the exponent, because each movement represents a "power of 10".

Andreyy89

Answer:

Explanation down below.

Step-by-step explanation:

10% of 91.25 = 9.125.

20% of 91.25 = 18.250.

30% of 91.25 = 27.375.

40% of 91.25 = 36.500.

36.500 × 2 = 73.

B, 70 dollars.

Graph the image of the figure using the transformation given. Don't forget prime marks on your new image. Part 1: reflection acr
amm1812

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

J (1, 4 ) → J' (- 1, 4 )

K (1, 0 ) → K' (- 1, 0 )

L (4, 3 ) → L' (- 4, 3 )

Plot the points J', K', L' and connect them in order to obtain image

If x+1/x = 5 find the value of x^3 +1/x^3. pls solve​
Korolek [52]

Answer:

1) solve x+1/x = 5

\frac{x + 1}{x}  = 5

x + 1 = 5x

x - 5x =  - 1

- 4x =  - 1

x =  \frac{ -1}{ - 4}

x =  \frac{1}{4}

2) solve x³+1/x³

x {}^{3}  +  \frac{1}{x {}^{3} }

substitute x = 1/4 into the expression

( \frac{1}{4} ) {}^{3}  +  \frac{1}{( \frac{1}{4}) {}^{3}  }

\frac{1}{64}  +  \frac{1}{ \frac{1}{64} }

\frac{1}{64}  +  \frac{64 \times 1}{1}

\frac{1}{64}   + 64

\frac{4097}{64}  \: or \: 64.02
