Write a numerical expression to represent the phrase.

the sum of 6 and the square of 12

Enter the correct answer in the box.

Answer:

$560

Step-by-step explanation:

Given that :

Principal, P= $500

Interest rate, r = 12% per year

Amount in account after 1 year

Time = 1 year

Using the relation :

A = P(1 + rt)

A = final amount in account

A = $500(1 + 0.12(1))

A = $500(1 + 0.12)

A = $500(1.12)

A = $560

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.

Answer:3

Step-by-step explanation:

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.

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:

x = (3.95 and -5.95)

Step-by-step explanation:

Given:

Hypotenuse = 9 cm

Perpendicular = (x+5) cm

Base = (x-3) cm

Find:

Value of x

Computation:

Using Pythagoras theorem

Hypotenuse² = Perpendicular² + Base²

9² = (x+5)² + (x-3)²

81 = x² + 25 + 10x + x² + 9 - 6x

2x² + 4x - 47 = 0

Quadratic Formula

x = [-b±√b²-4ac] / 2a

x = [-4±√16+376] / 2(2)

x = (3.95 and -5.95)

Answer: 50% would be the correct answer.

Complete question :

In Hawaii a volcano is about to explodel At 6:00 am a device placed inside the volcano

measures the temperature at 69.5 degrees Celsius. Every 3 minutes the temperature

rises 1/5 a degree. If the Volcano explodes at 145.5 degrees Celsius how many hours do

they have to evacuate a nearby city?​

Will Mark BRAINLIEST to the correct answer

Answer:

19 hours

Step-by-step explanation:

Given that:

Temperature of volcano at 6:00 am = 69.5°C

Average rise in temperature per 3 minute = 1/5

Hence, rise in temperature per minute = 0.0666666°C

Temperature at which volcano will explode = 145.5°C

Hence, change in temperature :

(145.5°C - 69.5°C) = 76°C

Hence, temperature will have to rise by 76°C

Rise in temperature / rate of temperature increase

= 76°C / 0.0666666°C

= 1140.0011 minutes

= 1140.0011 / 60

= 19.0000019 hours

= 19 hours

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.

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

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.

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

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.

Answer:

2.5%

Step-by-step explanation:

x=distance   y=time

x has been increased by 17%

100%+17% = 117%

y has been increased by 20%

100%+20%=120%

Now let's make the percentages into decimals. 117%=1.17 120%=1.2

To find the average speed you do the distance traveled divided by the time taken.

Average speed = 2.5%

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
