Answer:

P = \frac{4}{25}\\

Step-by-step explanation:

Big circle area:

A=\pi r^{2} =\pi (10)^{2} =100\pi

Smaller circle área:

A=\pi (4)^{2} =16\pi

Probability:

P=\frac{16\pi }{100\pi } =\frac{4}{25}

Hope this helps

An exponential function f(x) = ab^xpasses through the points (0, 2) and (3, 54). What are the values of a and
Vsevolod [243]

Answers:

a = 2

b = 3

=======================================================

Explanation:

Plug in x = 0 and y = 2 to find that

y = a*b^x

2 = a*b^0

2 = a*1

2 = a

a = 2

Then plug in x = 3 and y = 54 to determine the value of b

y = a*b^x

y = 2*b^x

54 = 2*b^3

2b^3 = 54

b^3 = 54/2

b^3 = 27

b = (27)^(1/3)

b = 3

So we have y = a*b^x update to y = 2*3^x

4. What is the volume of the cylinder? Express answer in terms of a (hold and
Vladimir [108]

Given:

Base area = 4π mm²

Height = 10 mm

To find:

The volume of the cylinder.

Solution:

Base of the cylinder is circle.

Area of the base = πr²

πr² = 4π

Volume of the cylinder = πr²h

Substitute 4π in place of πr².

                                      = 4π × 10

                                      = 40π mm³

The volume of the cylinder is 40π mm³.

the length of a chord of a circle is 24 cm long and is 5 cm away from the center of the circle what is the radius of the circle​
iogann1982 [59]

Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.

Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).
