Answers

Answer 1

Answer:

1/3, -2 and -1/2

Step-by-step explanation:

Given the polynomial function y = (3x − 1)(x + 2)(2x + 1)

The zeros of the function occurs at when y = 0

The expression becomes;

(3x − 1)(x + 2)(2x + 1) = 0

3x - 1 = 0

3x  = 1

x  = 1/3

Also

x = x+2

x = 0-2

x = -2

2x+ 1 = 0

2x = 0-1

2x = -1

x = -1/2

Hence the zeros of the polynomial are 1/3, -2 and -1/2

Divide 1 1/2 divided by 1/4 in simplest form

Answers

Answer:

6

Step-by-step explanation:

1 1/2 divided by 1/4. Firstly you simplify the mixed number 1 1/2 to an improper fraction to make the process easier. So if it is simplified it would be 3/2.

Now you follow the division process and then simply the answer and it would be 6.

Answer:

Answer is 6

Step-by-step explanation:

Change 1 1/2 into 3/2

Multiply by the reciprocal: 3/2 x 4/1

3/2 x 4/1 = 12/2

12 divided by 2 = 6

Answers

Answer:

$3.20 for the small and $4.70 for the large packages.

Step-by-step explanation:

multiply 3.20 by 1 since that is the price of mailing a small package and you want to mail 1.

multiply 4.70 by 4 since that is the price of a large one and you want to mail 4.

3.20 x 1 =3.20

Answer:

D. f(x)=900(0.07)^x.1,262

Step-by-step explanation:

You would have to use the P(1+r)^x

P= starting amount

R= rate of change or the percentage changed into a decimal

x= time

So it would be, 900(1+0.07)^5

calculating that you would get 1,262.3. but approximately it's 1,262.

Answers

Answer: t = 18.8 years

Step-by-step explanation: The modeled function is an exponential function:

[tex]P(t)=78,125e^{0.025t}[/tex]

which is farmland worth along time.

To determine when the farmland will be worth $125,000:

[tex]125,000=78,125e^{0.025t}[/tex]

[tex]e^{0.025t}=\frac{125,000}{78,125}[/tex]

[tex]e^{0.025t}=1.6[/tex]

Apply natural logarithm:

[tex]ln(e^{0.025t})=ln(1.6)[/tex]

And then, power rule:

[tex]0.025t=ln(1.6)[/tex]

[tex]t=\frac{ln(1.6)}{0.025}[/tex]

t ≈ [tex]\frac{0.47}{0.025}[/tex]

t ≈ 18.8

After 18.8 years, the farmland will reach market value of $125,000.

Pilar bought 2/3 pound of turkey. She ate 1/4 of the turkey that she bought for lunch.

How many pounds of turkey did she eat?

Enter your answer in the box as a fraction in simplest form.

Answer:

1/6 lbs

Step-by-step explanation:

2                 1                 1

-        X        -        =        -

3                  4                6

Answer: She ate 5/12 of the turkey.

Step-by-step explanation:

First, find a common denominator by multiplying each fraction by the denominator of the other. By doing this, you should get 8/12, and 3/12.

Next, subtract them!

ex: 2/3= 8/12

1/4=3/12

8/12-3/12=5/12

The length of a rectangle is one more than twice its width. If its perimeter is 20 inches, what is its length and width?

Answers

Answer:

Let length be L

Width be W

L=1+2W

Perimeter(p) of rectangle is

P=2L+2W

But L = 1+ 2W and p= 20

:. 20 =2(1+2W) +2W

20=2+4W+2W

18=6W

Divide both sides by 6

W =3

2W+1=L

6+1=L

L=7

Hence, length and width are 7in and 3in respectively

How to calculate 12 divided by 4

Long Division

Here we will show you step-by-step with detailed explanation how to calculate 12 divided by 4 using long division.

Before you continue, note that in the problem 12 divided by 4, the numbers are defined as follows:

12 = dividend

4 = divisor

Step 1:

Start by setting it up with the divisor 4 on the left side and the dividend 12 on the right side like this:

4 ⟌ 1 2

Step 2:

The divisor (4) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

0

4 ⟌ 1 2

Step 3:

Multiply the divisor by the result in the previous step (4 x 0 = 0) and write that answer below the dividend.

0

4 ⟌ 1 2

0

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

0

4 ⟌ 1 2

- 0

1

Step 5:

Move down the 2nd digit of the dividend (2) like this:

0

4 ⟌ 1 2

- 0

1 2

Step 6:

The divisor (4) goes into the bottom number (12), 3 time(s). Therefore, put 3 on top:

0 3

4 ⟌ 1 2

- 0

1 2

Step 7:

Multiply the divisor by the result in the previous step (4 x 3 = 12) and write that answer at the bottom:

0 3

4 ⟌ 1 2

- 0

1 2

1 2

Step 8:

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

0 3

4 ⟌ 1 2

- 0

1 2

- 1 2
