A. The constants of the linear factors are the opposite of the function's zeros.

B. A function's zeros can be determined by setting each linear factor equal to 0 and
solving.

C. If a function's zero is an integer, then the coefficient of the variable in the linear factor
must be one.

D. Multiplying the constants of the linear factors gives one of the function's zeros, and

It takes Scott 3 times longer to paint a house than it takes James. If they work together, they can paint the house in 13 hours. Write equation that could be used to solve for the amount of hours it takes each of them to paint the house alone.​

Answers

Answer:

I believe it is 13 - 3x

Step-by-step explanation:

Since we dont know how long it takes Scott to paint the house, we use x in its place. We are subtracting to find out how many hours it takes James. Once you get that answer divide by 3.

The equation that should be used to solve for the amount of hours should be considered to be 13-3x.

Calculation of the equation;

Since

It takes Scott 3 times longer to paint a house than it takes James. And,  they work together, they can paint the house in 13 hours.

So here we assume x to paint the house

So here the equation be like 13-3x.

Answers

Answer:

b = 29.31

Step-by-step explanation:

Given:

m<CEB = 68°

EB = radius = 15

Required:

Length of arc CD

Solution:

Length of arc CD = θ/360 × 2πr

Where,

θ = 180° - 68° = 112° (angles on a straight line)

π = 3.14

r = radius = 15

Plug in the values

Length of arc CD = 112/360 × 2 × 3.14 × 15

= 29.3066667

The ratio of the height to the base of a triangle is 3:4. If the base is 24 cm, what is its
area?

Answers

Answer:

height = 18 cm

Step-by-step explanation:

Let the height be 'x'

3 :  4 :: x : 24

Product of means =  product of extremes

4 *x = 24 * 3

     [tex]x = \frac{3 * 24}{4}\\\\x = 3 * 6\\\\x = 18[/tex]

Answer:

216cm^2

Step-by-step explanation:

If the ratio of height to base is 3:4 then

height = (3/4)*base

height = (3/4)*24cm = 18cm

Area = base*height/2 = 24cm * 18cm / 2 = 24cm * 9cm = 216cm^2

Pls answer this for me. How many paving stones, each 1m long and 80cm wide, are needed to cover a compound 13.6m long and 11m wide?​

Answers

Answer:

187 paving stones are needed

Step-by-step explanation:

Given

Paving stone

[tex]Length = 1m; Width = 80cm[/tex]

Compound

[tex]Length = 13.6cm; Width = 11m[/tex]

Required

Number of wires to cover the compound

Area is calculated as:

[tex]Area = Length * Width[/tex]

For the paving stone, we have:

[tex]A_1 =1m * 80cm[/tex]

Convert cm to m

[tex]A_1 =1m * 0.80m[/tex]

[tex]A_1 =0.8m^2[/tex]

For the compound, we have:

[tex]A_2 = 13.6m * 11m[/tex]

[tex]A_2 = 149.6m^2[/tex]

Divide the area of the compound by the area of the paving stone

[tex]n = \frac{A_2}{A_1}[/tex]

[tex]n = \frac{149.6}{0.8}[/tex]

[tex]n = 187[/tex]

Answer:

x = 5, y = -3

Step-by-step explanation:

2x - 3y = -1 ---› Eqn. 1

-2x + y = 7 ----› Eqn. 2

Add both equations

-2y = 6

Solve for y

y = 6/-2

y = -3

Substitute y = -3 into Eqn. 1.

2x - 3(-3) = -1

2x + 9 = -1

2x + 9 - 9 = -1 - 9

2x = -10

2x/2 = -10/2

x = 5

Solution: x = 5, y = -3

Point B has rectangular coordinates (-5, 12)
Write the coordinates (r, e) for point B. (O in degrees)

Answers

Answer:

(13, -67.4°)

Step-by-step explanation:

In the general case, for a point (x, y), the same point written in polar coordinates is (r, θ), such that:

r = √(x^2 + y^2)

θ = Atg(y/x)

Then if we have the point with coordinates (-5, 12)

The polar coordinates will be:

r = √((-5)^2 + 12^2) = 13

θ = Atg(12/-5) = -67.4°

Then the polar coordinates are:

(13, -67.4°)

Melvin couldn't believe his luck. He had always wanted to get a gold and purple Dynamite mountain bike. He was working hard at his chores and saving his allowance. Finally, he had enough money to buy the bike of his dreams. His father said they would go to the store on Saturday. Friday night, Melvin could hardly sleep. His mind was unable to rest as it raced with excitement and anticipation. After a few hours of counting sheep after sheep, he finally drifted off into a deep sleep where his dreams were vivid and realistic. He could feel the wind in his hair as he raced up and down the hills on his new mountain bike. In the morning, Melvin's father woke him up at 7 am sharp. After getting dressed and brushing their teeth, they got in the car and headed to the store. Melvin felt like he could burst with excitement! When his father asked if he was ready, Melvin quickly replied, "Are you kidding? I have been ready for months!" When they arrived at the store, Melvin sprinted to the back where the bikes were. His eyes glistened when he saw all the new, shiny bikes. His choices were endless! But there was only one that he really wanted. Melvin's eyes scanned back and forth for the gold and purple bike that he had been dreaming about, but he couldn't see it. He searched and searched up and down the aisles, but it was nowhere to be found. His heart sank with disappointment. It was the only one he really wanted, and now he couldn't get it. "I worked so hard for nothing! It's just not fair!" Melvin exclaimed as his shoulders slumped and he stormed away from the bikes. He just wanted to give up and go home, but Melvin's father told him not to worry. Like any dad would, he went and spoke to the store clerk. A few minutes went by as Melvin paced back and forth, anxiously awaiting his father's return. Sure enough, his dad came back with a huge smile on his face. He told Melvin that there was one gold and purple Dynamite mountain bike at the store across town, and that they would put it on hold for him.
