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]

Answer: GCF is 6

Explanation: the largest number all numbers are divisible by is 6, so that’s your greatest common factor. When you divide all numbers by 6 you are left with x^2+7x-8. The number in the center is always the number you need to add to, while the number at the right end of the equation is the number you have to multiply to.

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.

Answers

9514 1404 393

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

Find the measure of arc BC

Answer:

100°

Step-by-step explanation:

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 arc

The 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
