Answer: 8

{10}^{2}  = 100 \\  {6}^{2}  = 36 \\ 100 - 36 = 64 \\  \sqrt{64}  = 8

We want the equation of the line shown. All the answer choices are in slope intercept form. Let's find the slope and then match it with the right answer.

To do this, pick two points on the line and find the rate of change. We will pick (1,70) and (3,0).

slope: (70-0)/(1-3) = -35

Only the third equation works.

answer: third choice

Find a polynomial function with leading coefficient 1 that has the given zeros, multiplicities, and degree. Zero: 2, multiplicit
valkas [14]

Given:

Zero: 2, multiplicity: 3

Zero: 0, multiplicity: 2

Degree: 5

Leading coefficient = 1

To find:

The polynomial function.

Solution:

The general form of a polynomial is

P(x)=a(x-c_1)^{m_1}(x-c_2)^{m_2}...(x-c_n)^{m_n}

where, a is a constant, c_1,c_2,...,c_n are zeroes with multiplicity m_1,m_2,...,m_n.

Using the given information and the general form of a polynomial, we get

P(x)=a(x-2)^{3}(x-0)^{2}

P(x)=ax^2(x^3-6x^2+12x-8)

P(x)=a(x^5-6x^4+12x^3-8x^2)

Leading coefficient is 1, so the value of a is also 1.

P(x)=1(x^5-6x^4+12x^3-8x^2)

P(x)=x^5-6x^4+12x^3-8x^2

Therefore, the required polynomial is P(x)=x^5-6x^4+12x^3-8x^2.

Solve for x if the horizontal lines below are parallel.<br> fo
Bas_tet [7]

Answer:

x=82^{\circ}

Step-by-step explanation:

We can draw a perpendicular line through the two parallel lines to create a pentagon (there is an image attached in case you need to see where the line intersects the two parallel lines). Since the angle sum of a pentagon is 540^{\circ}, we can solve for x.

x+140+138+90+90 = 540 (Angle sum of pentagon is 540^{\circ})

x+458=540 (collect like-terms)

x=82^{\circ}

Hope this helps :)

Answer:

Kayla used mental math to find the final product of $11.97 x 5, but she made a mistake her steps are shown

Step 1: Round $11.97 to 12$  

Step 2 Multiply $12.00 x 5 = $60.00

<u>Step 3 Subtract $12.00 - $11.97 = 3.00 </u>     (It's meant to 0.03)

Step 4 Subtract $60.00 - $3.00 = $57.00

which step did she make her first mistake on
