Which graph represents the function f ( x ) = x 2 − 2 x + 1 ?

Answer:

The first 8 letters of the alphabet are:

{A, B, C, D, E, F, G, H}

To find the number of permutations, we can think of 8 positions. In each one of these positions, we can put one of the letters, now we need to find the number of possible options for each one of these positions, the total number of permutations will be equal to the product between all of these options.

Now, taking one letter at a time (to assign at each position)

For the first position, we have 8 options.

For the second position, we have 7 options (because one letter is already taken)

For the third position, we have 6 options (because two letters are already taken, one in the first position and another in the second)

For the fourth position, we have 5 options.

For the fifth position, we have 4 options.

For the sixth position, we have 3 options.

For the seventh position, we have 2 options.

For the last position, we have 1 option.

Then the total number of permutations is:

P = 8*7*6*5*4*3*2*1 = 40,320

Step-by-step explanation:

===================================================

Explanation:

f(x) = x^3 - 2x + 3

f ' (x) = 3x^2 - 2 ..... apply the power rule

f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point

f ' (1) = 1

If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value.

Now apply point slope form to find the equation of the tangent line

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

y = x - 1 + 2

y = x + 1   is the equation of the tangent line.

The graph is shown below. I used GeoGebra to make the graph.

Answer: $7.1

Step-by-step explanation:

Since the gallon of gas currently costs $3.17 and the prices are projected to increase 124% by April. Then, the projected cost of a gallon of gas in April will be:

= $3.17 × (100% + 124%)

= $3.17 × 224%

= $3.17 × 2.24

= $7.1

Therefore, the projected cost will be $7.1

Answer:

The answer for you here is D.

Step-by-step explanation:

A. makes no sense, I don't think I need to explain myself there lol.

B. and C. both pretty much say the same thing, since you can only pick one that makes those answers sketchy. Not to mention, if anything it would be MORE biased for the survey to allow people who don't even use the service to vote.

D. This one simply makes the most sense, as that is indeed something that varies greatly from person to person. (Also I got this one right on the test :P   )

The option that could affect the results of the survey is the answer options could be interpreted differently by different users.

The survey is meant to be taken only by those who use the service. The fact that the survey administered through the service instead of in person does not make the survey biased.

The question is too ambiguous and it can be interpreted differently by the users.

Answer:

you're correct the second one

Step-by-step explanation:

Answer:

4 inches

Step-by-step explanation:

Area of a circle = πr²

Where : = π = pi = 3.14

50.24 = 3.14 x r²

r² = 50.24 / 3.14

r² = 16

taking the square root of both sides

r = 4 inches

Answer:

Slop of the line M = -2

Step-by-step explanation:

Given coordinates;

(-1 , 1) , (3 , -7)

Find:

Slop of the line

Computation:

We know that;

x1 = -1

x2 = 3

y1 = 1

y2 = -7

Slop of the line M = Δy / Δx

Slop of the line M = (y2 - y1) / (x2 - x1)

Slop of the line M = (-7 - 1) / [3 - (-1)]

Slop of the line M = (-8) / [3 + 1]

Slop of the line M = (-8) / (4)

Slop of the line M = -2

Step-by-step explanation:

This question has missing details.

The given parameters from the complete question is:

[tex]Slushy\ Cup = \$5[/tex]

[tex]Refill = \$1[/tex]

Required

Total amount for 1 cup and 5 refills

Let

[tex]x \to[/tex] Slushy Cup

[tex]y \to[/tex] Refill

So, the expression for the total amount is:

[tex]Total = 5x + y[/tex]

[tex]x =1[/tex] -- 1 cup

[tex]y = 5[/tex] -- 5 refills

So, the total is:

[tex]Total = 5 * 1 + 5[/tex]

[tex]Total = 5 + 5[/tex]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Current population (PV)= 300,000

Increase rate (g)= 6% per year

To calculate the population after "n" years, we need to use the following formula:

FV= PV*(1 + g)^n

For example, after 10 years:

FV= 300,000*(1.06^10)

FV= 537,254

Answer:

425 miles per hour

Step-by-step explanation:

Find the speed per hour by dividing the distance by the number of hours:

6375/15

= 425

This means the plane traveled 425 miles in one hour.

So, the plane's average speed was 425 miles per hour

Answer:

1.05 * 10⁰

Step-by-step explanation:

Standard form is a way of representing either very large or very small numbers easily.

If a number is to be written in standard form, you have to first write down the number between 1 and 10, then you write × 10(to the power of a number).

Given that the amount of rain that fell near Marie's house is one and five hundredths inches of rain.

Amount of rain = one and five hundredths inches of rain = 1 + 5/100 = 1 + 0.05 = 1.05

Amount of rain in standard form = 1.05 * 10⁰
