8c² + 66c + 16

Step-by-step explanation:

Given

(c + 8)(8c + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

c(8c + 2) + 8(8c + 2) ← distribute both parenthesis

= 8c² + 2c + 64c + 16 ← collect like terms

= 8c² + 66c + 16

Answer:

[tex]\$14,187.27[/tex]

Step-by-step explanation:

we know that

In this problem we have a exponential decay function of the form

[tex]y=a(1-r)^x[/tex]

where

y ----> is the value of the boat in dollars

x ---> is the number of years

r ---> is the percent rate of change

a ---> is the initial value or y-intercept

we have

[tex]a=\$19,300\\r=5\%=5/100=0.05[/tex]

substitute

[tex]y=19,300(1-0.05)^x[/tex]

[tex]y=19,300(0.95)^x[/tex]

For x=6 years

substitute the value of x in the exponential function

[tex]y=19,300(0.95)^6\\y=\$14,187.27[/tex]

Answer:

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

The equation representing the proportional relationship between the number of laps Rosa runs and the amount of money she raises is y = 5x. This linear equation suggests that for every lap completed, $5 is earned for the hospital.

The relationship between the number of laps Rosa runs (x) and the amount of money she raises for the hospital (y) can be described by a linear equation because there is a proportional relationship between x and y. We can see from the values given that each lap corresponds to $5. Therefore, the slope (change in y divided by the change in x) is $rac{$5}{1 lap} = $5$ per lap. Since there is no initial fee mentioned (y-intercept, b), the equation is simply the slope times the number of laps.

So, we can write the equation as y = 5x. This equation tells us that for every lap Rosa runs, she will raise $5. If we plot this relationship on a graph with x as the independent variable and y as the dependent variable, we would get a straight line that passes through the origin (0,0).

Answer:

63

Step-by-step explanation:

The given expresion is

[tex]5 {e}^{2} - 4g + 7[/tex]

We want to find the value of this expression when e=4 and g=6.

We substitute these values to get:

[tex]5( {4}^{2} ) - 4(6) + 7[/tex]

We evaluate to obtain:

[tex]5(16) - 4(6) + 7[/tex]

Let us multiply out to get:

[tex]80 - 24 + 7[/tex]

This simplifies to 63

Answer:

The unit price is 63 cent per kilogram bag of rice.

Step-by-step explanation:

Given:

A 6-kilogram bag of rice costs $3.80.

Now, to find the unit price.

So, to get the unit price we use unitary method:

If cost of 6 kilogram bag of rice = $3.80.

Then cost of 1 kilogram bag of rice = [tex]\frac{3.80}{6}[/tex]  = [tex]\$0.633.[/tex]

Thus, the unit price is $0.633 per kilogram bag of rice.

Now, according to question we convert the unit price into cent by using conversion factor:

$1 = 100 cent

$0.633 = [tex]0.633\times 100=63.3\ cent.[/tex]

So, rounded to nearest cent  = 63 cent.

Therefore, the unit price is 63 cent per kilogram bag of rice.

Option B: [tex]\frac{1}{25}[/tex]

Solution:

Slope of the perpendicular lines:

If two lines are perpendicular then their slopes are negative reciprocals of each other.

[tex]$m_1=\frac{-1}{ m_2}[/tex]

Slope of the parallel lines:

If two lines are parallel then they have the same slope.

i.e their slopes are equal.

[tex]m_1=m_2[/tex]

Given line m and p are parallel.

Slope of the line m = [tex]\frac{1}{25}[/tex]

Using slope of the parallel lines definition,

Slope of the line p = slope of the line m

Slope of the line p = [tex]\frac{1}{25}[/tex]

Option B is the correct aswer.

Hence the slope of the of line p is [tex]\frac{1}{25}[/tex].

Answer:

y equals 2/3. u have to do 2/3 ×6 I'm pretty sure

Answer:

Step-by-step explanation:

Circumference of a circle means the perimeter of a circle and it is given be

Perimeter=2πr

P=2πr

Though π is a constant

But this question want us to find π

Make π the subject of the formula

Then, divide both side by

π=P/2r

Given that P=37.7cm

And diameter =12

And radius is half of diameter.

Therefore, radius =12/2=6cm

Then

π=P/2r

π=37.7/2×6

π=37.7/12.

Then, the last option is the correct option

Final answer:

To solve the equation -2.5(4x - 4) = -6, distribute -2.5 to the terms inside the parentheses, isolate the variable, and solve for x.

Explanation:

To solve the equation -2.5(4x - 4) = -6, we can start by distributing -2.5 to the terms inside the parentheses:

-10x + 10 = -6

Next, we can isolate the variable by subtracting 10 from both sides:

-10x = -16

Finally, we can solve for x by dividing both sides by -10:

x = -16/-10

Therefore, x = 1.6.

Final answer:

To determine the number of shareholders aged 40 and over, subtract the number of shareholders under 40 (55.5% of 91,000) from the total, resulting in 40,495 shareholders who are 40 and over.

Explanation:

The question asks how many shareholders are aged 40 and over in a fast food chain given that 55.5% are under 40 and there are a total of 91,000 shareholders.

First, we must find the number of shareholders under 40: 0.555 × 91,000 = 50,505 shareholders. Next, we subtract this from the total number of shareholders to find the number of shareholders aged 40 and over: 91,000 - 50,505 = 40,495 shareholders.

Therefore, 40,495 shareholders are aged 40 and over.

Option C:

[tex]$\sqrt[5]{34} =34^{\frac{1}{5} }[/tex]

Solution:

Given expression is [tex]\sqrt[5]{34}[/tex].

To write the given expression in rational exponent form.

Using rational exponent rule:

[tex]$\sqrt[n]{a^m} =a^{\frac{m}{n} }[/tex]

i. e. [tex]$\sqrt[\text{root}]{a^\text{power}} =a^{\frac{\text{power}}{\text{root}} }[/tex]

Given  [tex]\sqrt[5]{34}[/tex]

Here, root is 5 and power is 1.

Write it using the rational exponent rule,

[tex]$\sqrt[5]{34} =34^{\frac{1}{5} }[/tex]

Therefore option C is the correct answer.

Hence [tex]$\sqrt[5]{34} =34^{\frac{1}{5} }.[/tex]

Answer:

12 kilometers

$31 total fare

Step-by-step explanation:

7 + 2x   company A

19 + x .   Company B

set these equal and solve for x

x is number of kilometers

7 + 2x = 19 + x

2x = 12 + x

x = 12 kilometers

7 x 2 (12) = $31

Do 5*12 because that's 5*(4+4+4) which the 4s are the base lengths added together. So you have 60 for one part of the figure.

Next, you have 2*4 left to add on to the figure which is 8.

So 60+8=68 is your answer

68 units^2

Hope this helped!

Answer:

The area of the figure is 68ft^2

Step-by-step explanation:

To get the area look for the separate shapes in the figure, there are 2

One has the side lengths of 5ft and 12ft, to get the 12ft length see that one side is segmented into 3 4ft long lines.

5ft * 12ft= 60ft^2

The other shape has the side lengths of 2ft and 4ft

2ft*4ft= 8ft^2

60ft^2 + 8ft^2= 68ft^2

Jack should invest $8400 in the CD account and $3600 in the savings account.

Step-by-step explanation:

Jack wants to earn 7.5% interest per year. That implies he wants to earn

7.5/100*12000 per year i.e $900 per year.

Lets assume he invests X amount in the savings account. That leaves 12000-X to be invested in the CD account.

That implies,

[tex]4/100*X + 9/100*(12000-X) = 900[/tex]

=> [tex](4X+108000-9X)/100 = 900[/tex]

=> [tex]-5X = 90000-1080000 = -18000[/tex]

=> X = 3600

look at picture

Each share in the software company costs approximately $5,195.14 and each share in the biotech firm costs approximately $5,137.15.

To find out how much each share costs, we need to solve a system of equations. Let's call the cost of each share in the software company 'x' and the cost of each share in the biotech firm 'y'.

From the given information, we know that Dean purchased 14 shares in each company for a total cost of $812. This gives us the equation 14x + 14y = 812.

Similarly, Carrie invested a total of $5,767 in 100 shares in the software company and 99 shares in the biotech firm. This gives us the equation 100x + 99y = 5,767.

Now, we can solve this system of equations using either substitution or elimination method.

Using the elimination method, multiply the first equation by 99 and the second equation by 14 to make the coefficients of 'x' in both equations equal:

Now subtract the first equation from the second equation:

Divide by 14 on both sides to find the value of 'x':

Now substitute the value of 'x' back into one of the original equations to find the value of 'y'. Using the first equation:

Therefore, each share in the software company costs approximately $5,195.14 and each share in the biotech firm costs approximately $5,137.15.

Answer:

C

Step-by-step explanation:

You can already walk 0.9 of a mile in 3/8 so it cannot be A or B

C is the most reliable because even if you multiple the 0.9 by 3 so it is a little bit over a mile it is still closer to 2.4

Answer:

  A)  The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute

Step-by-step explanation:

When x=0 (no minutes have elapsed), the value of the function is ...

  f(0) = 75(2^0) = 75(1) = 75 . . . . the initial number of cells

As x increases by 1 (minute), the number of cells is multiplied by 2, so the 2 is the multiplier each minute. It indicates the number doubles. ("double" = "multiply by 2")

x is not defined, but for the function to make any sense, it must represent elapsed minutes.

Answer:

It remained 9/50 of the pie

Step-by-step explanation:

If Janelle ate 82% of the pie, now it remains:

100 - 82 = 18%

Let's convert 18% to fraction:

18% = 0.18 = 18/100

Let's simplify 18/100:

18/100 = 9/50 (Dividing by 2 the original fraction)

It remained 9/50 of the pie
