Erite 2 • 2•2 •2• 2 • 3•3•3• 3 in exponential form?

Answer:

[tex]\huge\boxed{\sf a = -12 , b = 8}[/tex]

Step-by-step explanation:

Given polynomial is:

[tex]f(x) = ax^3+ b^2 + 3x + 4[/tex]

[tex]\rule[225]{225}{2}[/tex]

First factor is (x-1)

Let x - 1 = 0  => x = 1

Putting this in the above polynomial

[tex]f(1) = a(1)^3 + b(1)^2 + 3(1) + 4[/tex]

Given that it's remainder is 3

[tex]3 = a + b + 3 + 4[/tex]

[tex]3 = a + b + 7[/tex]

Subtracting 7 to both sides

[tex]-4 = a + b\\OR \\[/tex]

[tex]\rule[225]{225}{2}[/tex]

Second Factor is 2x + 1

Let 2x + 1 = 0 => x = - 1 / 2

Putting in the above polynomial

[tex]f(-\frac{1}{2} ) = a (-\frac{1}{2} )^3 + b (-\frac{1}{2} )^2 + 3 (-\frac{1}{2} ) + 4[/tex]

The remainder is 6

[tex]6 = -\frac{a}{8} + \frac{b}{4} - \frac{3}{2} + 4\\6 - 4 = -\frac{a}{8} + \frac{b}{4} - \frac{3}{2}\\2 = \frac{-a + 2b -12 }{8} \\-a + 2b - 12 = 16\\-a + 2b = 16 + 12\\[/tex]

[tex]\rule[225]{225}{2}[/tex]

Adding both equations

a + b -  a + 2b = -4 + 28

3b = 24

Dividing both sides by 3

b = 8

[tex]\rule[225]{225}{2}[/tex]

Putting b = 8 in Equation (1)

a + 8 = -4

a = - 4 - 8

a = -12

Answer:

70%

Step-by-step explanation:

So, first, our set of choices is 10. This means that there are 10 choices.

We want a number that is greater than 5 or even. Thus, let's mark down all of our choices.

Numbers greater than 5 are:

6, 7, 8, 9, and 10.

Even numbers are:

2, 4, 6, 8, 10.

However, we already counted 6, 8, and 10 previously, so we'll ignore that.

All in all, the following numbers will satisfy our requirements:

2, 4, 6, 7, 8, 9, and 10.

This is 7 out of 10 numbers.

Therefore, our probability is:

[tex]7/10=70\%[/tex]

Answer:

c = (t - 2 + 7t) / 2

Step-by-step explanation:

We can isolate c, getting 2c = t - 2 + 7t.

Then, we can divide both sides by 2, getting c = (t - 2 + 7t) / 2.

Answer:

12 only.

Step-by-step explanation:

When the question is asking for f(0), it is asking for the value of y when x = 0.

We see that there is only 1 intersection at x = 0, and the y value would equal 12.

Therefore, our answer is 12 only.

Answer:

The answer is a.12 only its where the x coordinate stays 0 and the y coordinate decreases or increases

Answer:

3(3) + 0.75(2) = (3 + 0.75)x

Step-by-step explanation:

The cost per pound of the mixture is the total cost divided by the total weight.

3 lb granola at $3 per lb has a cost of 3(3)

0.75 lb of raisins at $2 per lb has a cost of 0.75(2)

The total cost is 3(3) + 0.75(2)

The mixture has an unknown cost per lb, so we call it x.

When you multiply the cost per lb of the mix by the total weight, you get the total cost.

Total weight of mix: 3 + 0.75

Cost per lb of mix: x

Total cost of mix: (3 + 0.75)x

Above, we know the total cost is 3(3) + 0.75(2)

We set these two amounts equal to get our equation.

3(3) + 0.75(2) = (3 + 0.75)x

Answer: 3(3) + 0.75(2) = (3 + 0.75)x

Answer:

Step-by-step explanation:

2x + 8 = 8

Subtract 8 from both sides.

2x = 0

Divide both sides by 2.

x = 0

The required number, eight more than twice a number is eight, is 0.

Given that,
To find the number which is eight more than twice a number is eight.

The technique in computation to use and analyze the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In mathematics, it vends on a number of procedures according to the declarations. There are four primary arithmetic operators, addition, subtraction, multiplication, and division,

Let the number be x,
The eight more than twice a number is eight. So,
8 = 2x + 8
2x = 0
x = 0

Thus, the required number, eight more than twice a number is eight, is 0.

#SPJ2

Answer:

Mary- $18

Jane- $30

Step-by-step explanation:

Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.

x(3+5) = $48

3x + 5x = $48

8x = $48

8x/8 = $48/8

x = $6

3($6):5($6) = $18:$30

Answer:

Mary = $18

Jane = $30

Step-by-step explanation:

The first thing you need to do is find out how much each part is.  To do that you need to add each side of the ratio together (3 + 5 = 8).  THen you set up an equation showing the 8 parts * x = 48 and solve for x.

8x = 48

x = 6 <--  Value of each part

Now you multiply the 6 by the number on each side of the ratio,

Mary = 3 * 6 = 18

Jane = 5 * 6 = 30

The above is your answer.

Answer:

[tex]\%Off-Campus = 45.5\%[/tex]

Step-by-step explanation:

Given

----------------------Dorms ---- Off-Campus ---- Total

Freshman -------- 88  ------  ---------12   ------- 100

Sophomore  ------62  ---------------38  --------- 100

Junior --------------43 -----------------  57  ---------- 100

Senior -------------25  -----------------75  ------------ 100

Total ---------------218 -------------182  --------------400

Required

Determine the percentage of off-campus students

From the above table, we have that:

[tex]Off-Campus = 182[/tex]

[tex]Total\ Surveyed = 400[/tex]

The percentage is then calculated as follows;

[tex]\%Off-Campus = \frac{Off-Campus}{Total-Surveyed} * 100\%[/tex]

[tex]\%Off-Campus = \frac{182}{400} * 100\%[/tex]

[tex]\%Off-Campus = 0.455 * 100\%[/tex]

[tex]\%Off-Campus = 45.5\%[/tex]

Answer:

You will know when to add or subtract because of keywords and symbols.

Step-by-step explanation:

Most addition and subtraction problems have keywords that tell you what operation to use. For example, so keywords that tell you that you have to add are altogether, sum, together, and a few other words. Some examples of subtraction problems are less than, and a bunch of other words.

Step-by-step explanation:

Let the amount of trail mix in each bag be x pounds. If Mario has [tex]2\frac{1}{4}[/tex] pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;

[tex]2\frac{1}{4} = 6 * x[/tex]

solving for x

[tex]\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\[/tex]

Hence 0.375 pounds of trail mix will be in each bag

Answer:

v10

Step-by-step explanation:

Turn the percentage into a decimal.

95% / 100 = 0.95

Multiply.

200 * 0.95 = 190

Subtract.

200 - 190 = $10

Therefore, the dress costs $10 on sale.

Best of Luck!

Answer: The answer is 190.

Answer:

5 days

Step-by-step explanation:

Set up linear equation; food= 240-12(day) f=240-12d

f(1)=240-12(1)=240-12=228

f(2)=240-12(2)=240-24=216

Now set food to equal 180, solve for days:

180=240-12d

-240  -240

-60=-12d

/-12  /-12

5=d

To check: f(5)=240-12(5)=240-60=180
