Answer:

I would go with letter B. -7

Step-by-step explanation:

The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:

y² + 15y + 56 = (y + 7)(y + a)

y² + 15y + 56 = y² + (7 + a)y + 7a

Step by step solution :

STEP  1 :

Trying to factor by splitting the middle term

1.1     Factoring  y2+14y+49  

The first term is,  y2  its coefficient is  1 .

The middle term is,  +14y  its coefficient is  14 .

The last term, "the constant", is  +49  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 49 = 49  

Step-2 : Find two factors of  49  whose sum equals the coefficient of the middle term, which is   14 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  7  and  7  

                    y2 + 7y + 7y + 49

Step-4 : Add up the first 2 terms, pulling out like factors :

                   y • (y+7)

             Add up the last 2 terms, pulling out common factors :

                   7 • (y+7)

Step-5 : Add up the four terms of step 4 :

                   (y+7)  •  (y+7)

The solution is:

  y  =  -7  

 The solution is:

 y = -14 / 2 = -7

Answer:

Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole.

Step-by-step explanation:

Using the Pythagorean Theorem, ([tex]a^2+b^2=c^2[/tex] ) we can measure the hypotenuse of a right triangle. Since the doorway is a rectangle, and a rectangle cut diagonally is a right triangle, we can use Pythagorean Theorem to measure the diagonal width of the doorway.

Plug in the values of the length and width of the door for a and b. The c value will represent the diagonal width of the doorway:

[tex]6^2+9^2=c^2[/tex]

[tex]36+81=c^2[/tex]

[tex]117=c^2[/tex]

Since 117 is equal to the value of c multiplied by c, we must find the square root of 117 to find the value of c.

[tex]\sqrt{117} =10.8[/tex]

[tex]10.8=c[/tex]

Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole, measuring 10 feet.

The number of points are:

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.

Circumference (or) perimeter of circle = 2πR

A Ferris wheel has a radius of 50 feet, and its center is 60 feet off the ground.

So, DA = r = 50 feet

OB = 30 feet

<AOC = 2 <AOB

          = 2 x arc sin (4/5)

and, Circumference = 2πr = 100π

Then, AC = (2π - 2 arc sin (4/5)) . 50

Let there are total p points

So, A= (1- arcsin (4/5)/π )p

Thus, 2 points for 30 feet off the ground.

and, 1 points for 110 feet off the ground.

and, 0 points for 5 feet off the ground.

Answer:

1. The answer would be A, Adjacent and supplementary

2.  The answer would be A supplementary.

Step-by-step explanation:

Supplementary angles add up to 180 degrees, both of the questions have angles that add up to 180 degrees. Adjacent mean that that the angle are next to each other in intersecting lines.

Answer:

x=12

Step-by-step explanation:

the (8x-17)° and (5x+19)° angles are corresponding angles

since lines are parallel and cut by a transversal, this means that these angles are congruent

to find x:

8x-17=5x+19

3x-17=19

Answer:

x = 7.5, y = 134

Step-by-step explanation:

Since both polygons are similar, hence the ratio of their similar sides will be equal to a constant;

Using the similarity theorem;

6/4 = x/5

4x = 6 * 5

4x = 30

x = 30/4

x = 7.5

Also;

y - 73 = 61

y = 73+61

y = 134

Hence x = 7.5, y = 134

i would say its C but im not 100% sure

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Just took the quiz

Based on the graphed values of f(x) and independent variable x, the graph shows that C. k is greater than zero.

We have a c value of -1 which is where the y axis is intercepted.

We know that k isn't zero because the x and y values are not the same. We can also tell that k is not less than 0 because if it was, the f(x) for the smaller x value would lead to a larger f(x) value.

The only logical conclusion therefore, is that k is greater than zero.

Answer:

Y = 15x + 30 and 8 hours

Step-by-step explanation:

She gets $15 per hour so her income is based on her hours, but we don't know what that is yet so, 15x.

She gets a solid $30 every week that is straight forward

To solve the function

150 = 15x + 30

subtract 30 from both sides

120 = 15x

divide 15 from both sides

8 = x

or

x = 8

Answer:

The correct answer is C.

Step-by-step explanation:

Giving the following information:

Present Value (PV)= 250 million

Future Value (FV)= 500 million

Growth rate (g)= 1% per year

First, we need to calculate the number of years required for the population to double:

n= ln(FV/PV) / ln(1+g)  

n= ln(500/250) / ln(1.01)

n= 69.66 = 70 years

It will take 70 years for the population to double.

Complete question is;

The city just assigned a second garbage truck to empty the bins in Kat’s neighborhood on trash day. The crew from the first garbage truck used to empty all the bins by themselves in 5 hours. In their training, it took the crew from the second garbage truck 8 hours to empty all the bins. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? To the nearest tenth, the first garbage truck will empty about of all the bins.

Answer:

Part of all bins first garbage truck will empty = 0.6

Step-by-step explanation:

Let the total number of bins emptied be denoted by n.

We are told that the crew from the first garbage truck empties all the bins in 5 hours. Thus

Work rate = (n/5) bins/hr

We are told the second garbage truck empties in 8 hours. Thus;

Work rate = (n/8) bins/hr

When both garbage trucks work together, the total amount of time spent will be denoted by x. Thus;

((n/5) + (n/8))x = n

Divide through by n to get;

x/5 + x/8 = 1

Multiply through by 40 to gwt;

8x + 5x = 40

13x = 40

x = 40/13 hrs

To find the part of all the garbage bins the first garbage truck empty when they work together, we will simply multiply the value of x by the work rate of the first garbage truck. Thus;

Part = (n/5) × (40/13)

Part = (40/65)n = 0.615 of n

To the nearest tenth gives 0.6 of n
