Answer:

C. Add 8 to both sides

Step-by-step explanation:

This is done in order to equate the equation to zero so that it relates to the general equation.

[tex] {ax}^{2} + bx + c = 0[/tex]

c is (13 + 8)

Answer:

By definition the area of a rectangle is:

A = l * w

Where,

l: long

w: width

So we have to clear the width:

w = A / l

Substituting the values:

w = (234) / (18) = 13

w = 13 feets

answer

the width, in feet, of the room is 13

Answer:

1) The polar form of that equation will be r= √5cos(2θ)

2) i am stuck on this one (sorry)

Step-by-step explanation:

(i) We know that [tex]x = r\cos{\theta}\:\text{and}\:y = r\sin{\theta}.[/tex] So we can write the given equation as

[tex]r^2\cos^2\theta - r^2\sin^2\theta = 5[/tex]

[tex]\Rightarrow r^2(\cos^2\theta - \sin^2\theta) = 5[/tex]

[tex]r^2 = \dfrac{5}{(\cos^2\theta - \sin^2\theta)}[/tex]

[tex]\:\:\:\:\:=\dfrac{5}{\cos{2\theta}} = 5\sec{2\theta}[/tex]

(ii) Recall that

[tex]\cot{\theta} = \dfrac{\cos{\theta}}{\sin{\theta}}[/tex]

[tex]\csc{\theta} = \dfrac{1}{\sin{\theta}}[/tex]

so we can write r as

[tex]r = 8\cot{\theta}\csc{\theta}[/tex]

[tex]\:\:\:\:= 8\left(\dfrac{\cos{\theta}}{\sin{\theta}}\right)\left(\dfrac{1}{\sin{\theta}}\right)[/tex]

[tex]\:\:\:\:= 8\left(\dfrac{x}{y}\right)\!\left(\dfrac{r}{y}\right) = \dfrac{8xr}{y^2}[/tex]

Upon simplification, we get

[tex]y^2 = 8x[/tex]

Answer:

Answer:

$765

Step-by-step explanation:

If an amount of money, P, called the principal, is invested for a period of t years at an annual interest rate r, the amount of interest, I, earned is given by

I =Prt           where

I =interest

P =principal

r =rate

t =time

The following information is given.

Prt=$3,600=4.25%=5 years

Substituting the given information into the simple interest formula and solving for I gives

I =Prt

I =(3,600)(0.0425)(5)

=765

The amount of interest Kelsey earned in 5 years was $765.

Answer:

15

Step-by-step explanation:

Answer:

The answer is 15

Step-by-step explanation:

Answer:

87

Step-by-step explanation:

number of sausage buns = s

number of custard buns = c

at the start of the day, s = c

at the end of the day

c+27=6(s-68)

since c = s,

s+27=6(s-68)

s+27=6s-408

-5s = -435

s=87

Let us represent:

The number of sausages baked at first =  s

The number of custard buns baked at first =  c

       s - 68

        c + 27

Hence:

c + 27 = 6 (s - 68)

c + 27 = 6s - 408

        c = s

Hence,

c + 27 = 6s - 408

s + 27 = 6s - 408

Collect like terms

408 + 27 = 6s - s

435 = 5s

Divide both sides by 5

435/5 = 5s/5

s = 87

Therefore, the number of sausage buns Sam baked at first is 87 sausage buns.

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

-3x + 7 < 11

-3(-5) + 7 < 11

Multiplying two negatives together, makes a positive number.

15 + 7 < 11

22 < 11

22 less than 11 is false, therefore -5 is the correct answer.

Answer:  Either 6 or 8

Explanation:

Notice that the first, third and fifth values are: 6,12,24. It appears the pattern here is "times 2". So we double each value to get the next item. This only seems to apply for the odd numbered slots.

For the even number slots, we have the pattern: 2,4. The next item isn't clear. We could do two things

If we go with the first option, then we have 4+2 = 6 as the next term

OR

If we go with the second option, then we have 4*2 = 8 as the next term

Unfortunately, there isn't enough information to know which would actually be the next term. A common problem with sequence problems like this is that there are often many ways to generate the same subsequence, which leads to ambiguity as to what the next term would be.

Answer:

A Rectangle

Step-by-step explanation:

A longitudinal section means that the plane slicing the cylinder is vertical, just as a latitudinal section means that the slice is horizontal.

When you think about it, a flat slice of a cylinder in the vertical direction is a rectangle.

If the cylinder is sliced along the length of the cylinder then the shape we get is a rectangle. Then the correct option is B.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

If you were to take a longitudinal section from a long cylinder.

Then the shape we get will be

If the cylinder is sliced along the length of the cylinder then the shape we get is a rectangle.

Answer:

∠ ABF = 120°

Step-by-step explanation:

HCI is a straight line , so

3x + 2x + 4x = 180 , that is

9x = 180 ( divide both sides by 9 )

x = 20

∠ ABF and ∠ BCI are corresponding angles and are congruent , so

∠ ABF = 2x + 4x = 6x = 6(20) = 120°

Answer:

   2440

Step-by-step explanation:

The difference in fixed costs is ...

  37815 -16465 = 21350

The difference in variable costs is ...

  20.50 -11.75 = 8.75 . . . . per book

Then the number of books that must be produced for the difference in variable costs to be equal to the difference in fixed costs is ...

  21350/8.75 = 2440

For production of 2440 books, the costs of the two methods will be the same.

Additional comment

You can write expressions for total cost of each production method. When you set them equal and solve for the number of books, you find the math you end up doing is the same as that shown above.
