First, find the probability that you will pull a yellow marble. There are 9 yellow marbles and 22 total, so the probability is 9/22. Then, find the probability that you will pull a green marble. There are 7 green out of 22 so the probability is 7/22. To find the probability of both, multiply them.
9/22 * 7/22 is 63/484

An isosceles right triangle is inscribed in a circle. The hypotenuse of the triangle is the diameter of the circle. Write a function f in terms of x that represents the area of the shaded region. Leave your answer in terms of π.

Answer:
f(x) = (π-2)x^2/4
Step-by-step explanation:
The area of the triangle is ...
A = 1/2(x)(x) = (1/2)x^2
The hypotenuse of the triangle is x√2, so the radius of the circle is x/√2. That means the area of the semicircle is ...
A = 1/2πr^2 = (π/2)(x/√2)^2 = (π/4)x^2
The shaded area is the difference between the semicircle area and the triangle area.
f(x) = (π/4)x^2 -(1/2)x^2
f(x) = (π-2)x^2/4

What is the coordinate points of (1/2,√3/2) when reflected to quadrant 3?
Answers
Answer:
(-√3/2., -1/2)
Step-by-step explanation:
This is a reflection in the line y = -x.
So x = 1/2 becomes y = -1/2
and y = √3/2 becomes x = -√3/2.

Find the measure of arc BC
Answers
Answer:
100°
Step-by-step explanation:
is 25% of the circle
Answer:
BC = 100°
Step-by-step explanation:
The chord- chord angle BDC is half the sum of the arcs intercepted by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex] ( BC + AE) = 85° ( multiply both sides by 2 to clear the fraction )
BC + AE = 170°
BC + 70° = 170° ( subtract 70° from both sides )
BC = 100°

In circle Q with m PQR = 82 and PQ = 5 units, find the length of arc PR.
Round to the nearest hundredth.
Answers
The length of arc PR to the nearest hundredth is 7.15 units
How to calculate the length of an arcThe formula for calculating the length of an arc is expressed as:
L = r theta
Given the following parameters
r = PQ = 5 units
theta = <PQR = 82π/180 rad
Substitute to have:
L = 5 * 82π/180 rad
L = 7.15 units
Hence the length of arc PR to the nearest hundredth is 7.15 units

Xpand the binomial (4x + 3y)3. The coefficient of the second term in the expansion of the binomial (4x + 3y)3 is .
Answers
Answer: 144
Step-by-step explanation:
The binomial is [tex]\left( 4x+3y\right)^3[/tex]
The expansion of [tex]\Rightarrow \left ( a+b \right )^n=^nC_0\left ( a \right )^n\left ( b \right )^0+^nC_1\left ( a \right )^{n-1}\left ( b \right )^1+^nC_2\left ( a \right )^{n-2}\left ( b \right )^2+^nC_3\left ( a \right )^{n-3}\left ( b \right )^3+\ldots[/tex]
Expansion of [tex]\left( 4x+3y\right)^3[/tex]
[tex]\Rightarrow ^3C_0\left ( 4x\right )^{3}\left ( 3y\right )^0+^3C_1\left ( 4x\right )^{2}\left ( 3y\right )^1+^3C_2\left ( 4x\right )^{1}\left ( 3y\right )^2+^3C_3\left ( 4x\right )^{0}\left ( 3y\right )^3[/tex]
So, the second term is
[tex]\Rightarrow ^3C_1\left ( 4x\right )^{3-1}\left ( 3y\right )^1\\\Rightarrow ^3C_1\left ( 4x\right )^{2}\left ( 3y\right )^1[/tex]
Its Coefficient is
[tex]\Rightarrow ^3C_1\times 4^2\times 3\\\Rightarrow 3\times 16\times 3=144[/tex]
