Given f (x)= -x (x + 6), what is f (-3)?

Answer:

10

Step-by-step explanation:

9514 1404 393

Answer:

  C.  The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).

Step-by-step explanation:

The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.

Additionally, the x-term needs to match the result of multiplying out the factors.

  B.  (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)

  C.  (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)

The factors of C are zero when x=-1, x=5/2.

Answer:

1250 women

Step-by-step explanation:

1500 / 6 = 250

250 x 5 = 1250

hope this helps

Answer:

There are 1,250 women

Step-by-step explanation:

If the ratio of men to women is 6 to 5, and there are 1,500 men, the actual ratio of men to women is 1,500 to x, where x is equal to the amount of women at the college.

Since 6/5 is equal to 1,500/x, you cross multiply to find that 7,500 is eual to 6x.

Divide both sides by 6 to find that x is equal to 1,250 women.

Answer:

A

Step-by-step explanation:

Answer:

Luka had 6 slices, Kira had 9 slices and Ali 12 slices

Step-by-step explanation:

Each had 2/3 of their slices hence

Luka = 3/2 x 4 slices = 6

Kira = 3/2 x 6 slices = 9

Ali = 3/2 x 8 slices = 12

Answer:

M = 95°

N = 67°

Step-by-step explanation:

180 - 162 = 18°

6y + 5 + 4y + 7 + 18 = 180

10y + 30 = 180

10y = 150

y = 15

M: 6(15) + 5 = 95°

N: 4(15) + 7 = 67°

Verification: 95 + 67 + 18 = 180° (correct)

Answer:

Step-by-step explanation:

1. Write your formula

2. Plug it in

3. Solve

these steps will help you out with all of your surface area problems.

Like this

Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...

V = Bh                            (Pie is also known as 3.14)

your big (B) is (pie times r squared) Then you add your height.

so your formula will look like this...

V = pie times r squared...

the full formula will be...

V = (3.14) times (2.5 squared) times the height which in this case is (12)

everything together will be...

V = (3.14) (2.5^2) (12)

all you have to do is multiply all of that and you will get your answer.

The answer is...

V = 236 inches ^2                        (Just a tip, the ^ sign means to the power of)

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].

Answer:

[tex]W=\sqrt{F}[/tex]

Step-by-step explanation:

The given relation is as follows :

[tex]F=W^2[/tex]

We need to rearrange it to make W the subject.

When square gets removed from W, it goes to F and it will form as follows :

[tex]W=\sqrt{F}[/tex]

Hence, this is the required solution.

The measure of <B and <D are 110 degrees and 70 degrees

The sum of the opposite angle of the quadrilateral within the circle is 360 degrees.

Given the following parameters

<B = 3x - 4

<D = 2x - 6

Equate both equations

<B + <D = 180

3x - 4 + 2x - 6 = 180

5x - 10 = 180

5x = 190

x = 190/5

x = 38

Determine the measure of <B and <D

<B = 3x - 4 = 3(38) - 4

<B = 110 degrees

<D = 2x - 6

<D = 2(38) - 6

<D = 76 - 6

<D = 70 degrees

Hence the measure of <B and <D are 110 degrees and 70 degrees
