Mrs. Corazza paid $38.64 to fill up 12 gallons of gasoline in her car. What is the price for 1 gallon of gasoline?

Answer:

[tex]a_n = 1 + 5(n-1)[/tex]

$36

Step-by-step explanation:

I think the part that is confusing you is how to read the math syntax.

The part that says "[tex]a_n=1, if\ n=1[/tex]" just means that a=1 is your starting number. The n=1 is the first iteration.

The part that says "[tex]a_{n}=a_{n-1}+5\ , if\ n>1[/tex]" just means that you add 5 to the previous number every iteration.

They want you to find the number at 8th iteration, n=8. So lets work it out.

n=1:  a= 1

n=2: a= 1+5 = 6

n=3: a= 6+5 = 11

n=4: a= 11+5 = 16

n=5: a= 16+5 = 21

n=6: a= 21+5 = 26

n=7: a=26+5 = 31

n=8: a= 31+5 = 36

Or you can use the shortcut:

You're always adding by 5 each time and starting with 1, so:

[tex]a_n = 1 + 5(n-1)[/tex]

where n=8 for the 8th round.

[tex]a_n = 1 + 5(8-1) = 36[/tex]

Answer:

x = 15

Step-by-step explanation:

We are told that a right angle is divided into two parts

A right angle = 90°

Part A = 30°

Part B = 4x

Hence:

30° + 4x = 90°

Collect like terms

4x = 90° - 30°

4x = 60°

4x = 60/4

x = 15

Therefore, the value of x = 15

Step-by-step explanation:

The line is a horizontal line of the form y = a, where a is a real constant.

Since the line passes through the points (-4, 1) and (2, 1) with y-values of 1,

Equation of the line: y = 1.

Switch to the other streaming service

Step-by-step explanation:

So, 96$ with a 12% increase is $107.52.

But if you do 8.75×12 you get $105.

So Clare should switch to the other music stream.

Answer:3

Step-by-step explanation:

Answer: A

Step-by-step explanation:

If you look at option A and ignore the -(x+2)^2, it would say f(x) = -3.

So the vertex has y-coordinate -3.

Because the coefficient of -(x+2)^2 is negative, the graph opens downward.

Because it says -(x+2)^2 instead of -(x-2)^2, it will be on the left side of the graph.

The graph meets all of these conditions.

The graph described in option B opens upwards.

The graph described in option C opens upwards and the vertex is in the fourth quadrant.

The graph described in option D opens downwards, but the vertex is in the fourth quadrant.

Inches to CM Conversion

1 Inch (in) is equal to 2.54 cm. To convert inches to cm, multiply the inch value by 2.54. For example, to find out how many cm is 12 inches, multiply 12 by 2.54, that makes 30.48 cm is 12 in.

Answer:

im trying to do a challenge because this kid deleted all my answers

Step-by-step explanation:

Step-by-step explanation:

X-value of Midpoint of J(-7, -2) and M(-6, -4)

= [(-7) + (-6)] / 2 = -6.5.

Y-value of Midpoint of J(-7, -2) and M(-6, -4)

= [(-2) + (-4)] / 2 = -3.

X-value of Midpoint of K(-2, -2) and L(-3, -4)

= [(-2) + -3)] / 2 = -2.5.

Y-value of Midpoint of K(-2, -2) and L(-3, -4)

= [(-2) + (-4)] / 2 = -3.

We have (-6.5, -3) and (-2.5, 3).

The correct answer is Option D.

Given:

In triangle ABC, Q is the centroid and FQ=9.

To find:

The length of FC and QC.

Solution:

We know that, centroid is the intersection point of medians of a triangle and medians divide teach other in 2:1. So, centroid divided each median in 2:1.

CF is a median and Q is the centroid. So,

[tex]QC:FQ=2:1[/tex]

Let the length of QC and FQ are 2x and x respectively.

We have, FQ=9.

[tex]x=9[/tex]

Now,

[tex]QC=2x[/tex]

[tex]QC=2(9)[/tex]

[tex]QC=18[/tex]

And,

[tex]FC=FQ+QC[/tex]

[tex]FC=9+18[/tex]

[tex]FC=27[/tex]

Therefore, the length of FC is 27 units and length of QC is 18 units.

Answer:

The x- and y-coordinates are switched

Step-by-step explanation:

Here, we want to identify the error in the plot

1.5 units to the left, that is negative x-axis (-1.5)

4 units up is 4

So the coordinate point is (-1.5,4)

So the error on what he gave was that both coordinates were switched

Answer:

c

Step-by-step explanation:

9514 1404 393

Answer:

  c ∈ {3.4, 20.6}

Step-by-step explanation:

The law of cosines can be used to write a quadratic equation in c.

  a^2 = b^2 + c^2 -2bc·cos(A)

  10^2 = 13^2 + c^2 -2(13)c ·cos(23°)

  c^2 -23.933c +69 = 0 . . . . . subtract 100 to put into standard form.

  c = (-(-23.933) ±√((-23.933)^2 -4(1)(69)))/(2(1))

  c ≈ 11.967 ± √74.199

  c ≈ {3.4, 20.6}

_____

Additional comment

The given angle is opposite the shorter of the two given sides, so we expect two solutions. We could use the law of sines, but this works just as well and gives the two solutions directly, without having to find angle B.

Answer:

C

Step-by-step explanation:

Here's a trick:

Find the last number of the equation and look at your factors to see which numbers you can multiply to get that answer

in this case the last number of x^3-8x^2+17x-10 is -10

*IF IT HAS A NEGATIVE, ALWAYS REMEMBER TO INCLUDE IT*

Then look at the options and see what numbers can get you -10 but include the factor that they give you.

in this case C has the numbers as -1×-5×-2 gives you -10

now to check by using the box method, which is much easier to do, and put pick 2 of those factors and check if it's right

Question:

A paintball court charges an initial entrance fee plus a fixed price per ball. P represents the total price (in dollars) as a function of the number of balls used n.

P=0.80n+5.50

What is the price for 10 balls, not including the entrance fee?

Answer:

$8

Step-by-step explanation:

We are given the function:

P=0.80n+5.50

Where n represents the number of balls. From this function, the entrance fee = 5.50

We are asked to calculate the price for 10 balls without the entrance fee. This is given as:

0.80n = 0.80 × 10 balls

= $8

The price for 10 balls, not including the entrance fee is $8

Answer:

The answer is 8

Answer:

- 2 1/8 degrees

Step-by-step explanation:

Given

Initial temperature of a solution = -5/8 degrees

Amount drop = 1 1/2 degrees

Temperature after the drop = -5/8 - 1 1/2

Temperature after the drop = -5/8 - 3/2

Temperature after the drop = -5-12/8

Temperature after the drop = -17/8

Hence the temperature after the drop is - 2 1/8 degrees

The domain is the x value and the range is the y value.

Because x is a variable it can be any real number so the domain would be negative infinity to infinity.

Because the domain is negative infinity to infinity, then the range is also negative infinity to infinity.
