Find f(2) if f(x) = (-2x)^2 / (7x-4)

Answers

Answer 1

Answer:

4/3

Step-by-step explanation:

f(2) = (-2*2)^2 / (7(2))-4)

f(2) = (-4)^2 / 14-4

f(2) = 16 / 12

f(2) = 4 / 3

4) Good Work Company charges by the word to run classified ads. This company charges $12 for
the first 15 words and $0.55 for each additional word.
a. How much would a 25-word classified ad cost?
b. How much would a 50-word classified ad cost?

Answers

Equation::

Rate of change=0.55$

If words be x

Equation in slope intercept form

y=12+0.55x, x≥15

So

#1

More words=25-15=10

Cost:-

y=12+0.55(10)=12+5.5=17.5$

#2

Extra words=50-15=35

Cost:-

y=12+0.55(35)=12+19.25=29.25$

Answer:

a. $17.50

b. $31.25

Step-by-step explanation:

a.

For $12 you get 15 words.

For a 25-word ad, you need 10 more words than the 15 you get for $12, so you must add 10 words at $0.55 per word.

cost = $12 + 10 × $0.55

cost = $12 + $5.5

cost = $17.50

b.

50 words is 25 words more than 25 words, so you must pay for 25 words more than the cost of the 25-word ad in part a.

cost = $17.50 + 25 × $0.55

cost = $17.50 + $13.75

cost = $31.25

Which steps could be part of the process in algebraically solving the system of equations, y 5x = x2 10 and y = 4x – 10? select two options. y = x2 5x 10 y 5x = x2 10 4x – 10 0 = x2 – 9x 0 = x2 – 9x 20 one x-value of a solution to the system is 4.

Answers

Answer:

That would be :

4x – 10 = x2 – 5x + 10  ( y = 4x - 10 is substitute for y)

PROOF:        y + 5x = x² + 10

                    (4x - 10) + 5x = x² + 10

                     4x - 10  =  x² -5x + 10

   0 = x2 – 9x + 20  (liked terms are grouped and simplified)

PROOF:      4x - 10  =  x² -5x + 10

                  4x = x² -5x + 10 + 10

                   0  = x² -5x -4x + 20

                   0  = x² - 9x + 20

Solving:

            x² - 9x + 20 = 0

            x² - 5x - 4x + 20 = 0

            (x - 5) (x - 4)  = 0

         ⇒ x = 4  (as question says) OR x = 5

Answers

Answer:

See below ~

Step-by-step explanation:

Converting a decimal to a fraction :

Multiply by 100/100 and keep in the form without division

A. (0.47)

0.47 x 100/10047/100

B. (-0.47)

-0.47 x 100/100-47/100

C. (0.--47)

A minus sign multiplied by another minus sign makes a positive sign0.--47 ⇒ 0.4747/100

Answer:

Part (a) = 47/100, Part (b) = -47/100, Part (c) = 47/100

Step-by-step explanation:

Step 1:  Determine 0.47 as a fraction

0.47 can also be expressed as 47% which means that there is 47/100.  We can see that there is no way that we can simplify the fraction even more so that is our final answer.

Step 2:  Determine -0.47 as a fraction

0.47 can also be expressed as -47/100.  We can see that there is no way that we can simplify the fraction even more so that is our final answer.

Step 3:  Determine --0.47 as a fraction

Two negatives (-), means that they cancel out and cause a positive (+).  For example, -1 * -1 gives us 1.  Therefore it would just be like the first one which is 47/100.

Answer: Part (a) = 47/100, Part (b) = -47/100, Part (c) = 47/100

Solve the following ⇒ 8x-5=5(x-4)

Answers

Answer:

x = -5

Step-by-step explanation:

Given:

[tex]\displaystyle \large{8x-5=5(x-4)}[/tex]

Distribute 5(x-4):

[tex]\displaystyle \large{8x-5=5x-20}[/tex]

Add both sides by 5:

[tex]\displaystyle \large{8x-5+5=5x-20+5}\\\displaystyle \large{8x=5x-15}[/tex]

Subtract both sides by 5x:

[tex]\displaystyle \large{8x-5x=5x-15-5x}\\\displaystyle \large{3x=-15}[/tex]

Divide both sides by 3:

[tex]\displaystyle \large{\dfrac{3x}{3}=\dfrac{-15}{3}}\\\displaystyle \large{x=-5}[/tex]

Therefore, your solution is x = -5

Answer:

x = -5

Step-by-step explanation:

8x - 5 = 5(x - 4)

Distributing the value in the RHS

5(x - 4)5(x) - 5(4)5x - 20

Equating to the RHS

8x - 5 = 5x - 20

Bring x terms to the left and numbers to the right.

8x - 5x = -20 + 53x = -15

Divide both sides by 3.

3x/3 = -15/3x = -5

You find another case with a sale price of $4.68 after a 40% discount. What is the original price of the case?

Answers

Answer:

11.7

Step-by-step explanation:

Since we know what the price was after the discount, we just have to reverse it. In order to apply a discount to a price, you multiply the number by the discount. e.g, 0.40 * x = 4.68. So to find the original price, we have to do the opposite. The opposite of multiplication is division, so divide 4.68 by 0.40, (0.40 is equivalent to 40%.) and we get 11.7.

11.7 is the original price.

The first thing you need to do is:you have a square whose area is 11^2 = 121 square inches.then we are going to multiply the radius to the PI which is 3.14 the area of the circle with radius 4 is equal to 3.14 * 4^2 = 3.14 * 16 = 50.24you need to divide the calculated radius times pi (3.14) you can get the answer and you need to round your answer to the nearest hundredththe probability that the dart will hit within the circle is equal to 50.24 / 121 = 0.4152066116 which is rounded to .04152 or 41.52%this assumes the dart will always hit the square at least.

I think of a number . If I subtract six from it and multiply the difference by 4 the result is 36. Evaluate the number that I thought of.

Answers

Answer:

15

Step-by-step explanation:

First we can make an equation by replacing the unknown number with x :

First step of problem:

x-6

Second part of problem:

4(x-6)

Third part of the problem:

4(x-6)=36

First we can expand the bracket to give us:

4x-24=36

Now we add 24 to both sides:

4x = 60

Now we divide both sides by 4 for our final answer of

x= 15

To check this answer we can put it back into the problem:

4(15-6)=36

4(9)=36

Therefore our answer that was thought was 15.

then the equation that models its path would be h(t) =

path: What is the height of the cannonball before it is launched,
at t=0? Remember to include units

Answers

Answer:

29.4 m

Step-by-step explanation:

From the graph

You can clearly infer from the graph that the initial height of the cannon ball, before it is launched is 29.4 mJust find t = 0, and see where the line of the graph intersects the y-axis, which represents height of the cannon ball w.r.t time.

From the equation

An even simpler method is substitute t = 0 into the equation for the motion of the cannon ballh(0) = -4.9(0)² + 24.5(0) + 29.4h(0) = 29.4 m
