Answer:

Circumcenter

Step-by-step explanation:

The center that is created by intersection of the three perpendicular bisectors of your triangle sides.

To model the number of enrolled students, y, x years after the program began, we can use an exponential equation in the form:

y = ab^x

where a is the initial number of students, b is the growth factor, and x is the number of years after the program began.

We are given that the initial number of students was 245, and that the number of enrolled students after one year is 294. Therefore, we can use these values to find the growth factor b:

294 = 245b^1

b = 294/245

b = 1.2

Now that we know the growth factor, we can write the exponential equation in the form y = a(1.2)^x:

y = 245(1.2)^x

This equation can be used to model the number of enrolled students, y, x years after the program began, assuming that the advertising strategy continues to be successful and the growth rate remains constant.

Answer:

Angle A = tan^-1(11/5)
Angle C = 90 - tan^-1(11/5)
AC = sqrt(146)

Step-by-step explanation:

As this is a right triangle, we can apply the Pythagorean theorem a^2 + b^2 = c^2, where c is the hypotenuse while a and b are the legs, to solve for AC.

11^2 + 5^2 = AC^2

121 + 25 = AC^2

146 = AC^2

sqrt(146) = AC^2

Next, to find angle A, we can use one of the trigonometric functions. Let’s use tangent for simplicity. Tangent of an angle is “opposite divided by adjacent”. If we set the angle to A, opposite is side BC and the adjacent is side AB. Thus, tan(A) = 11/5 and tan^-1(11/5) = A.
Since the sum of angles in a triangle is 180, we can find angle C by setting up this equation: C = 180 - 90 - tan^-1(11/5), which is 90 - tan^-1(11/5)

Answer:

9 laps takes 5 minutes 25 seconds.

Step-by-step explanation:

Here is given:

4 laps takes 6 minutes 12 seconds.

We have to find how long 1 lap takes.

4/4 6/4 12/4 --> 1 lap takes 2 minutes 33 seconds.

Now, multiply each by 9 because you want to find 9 laps, so:

1x9 2x9 33x9 --> 9 laps takes 5 minutes 25 seconds.

The x-intercepts of the function y = (x-5)(x+3) are 5 and -3.

To find the x-intercepts of the function y = (x-5)(x+3), we need to set y equal to zero and solve for x.

The x-intercepts are the values of x where the graph of the function intersects or crosses the x-axis.

Set y = 0:

0 = (x-5)(x+3)

Apply the zero-product property:

The product of two factors is equal to zero if and only if at least one of the factors is equal to zero.

Therefore, we can set each factor equal to zero and solve for x.

Setting x-5 = 0:

x - 5 = 0

x = 5

Setting x+3 = 0:

x + 3 = 0

x = -3.

The x-intercepts of the function y = (x-5)(x+3) are x = 5 and x = -3.

These are the values of x where the graph of the function crosses the x-axis.

Answer: negative one third

Answer:

-1/3

Explanation:

There's a formula that I'll use to find the slope - it's called the slope formula.

\(\sf{m=\dfrac{y_2-y_1}{x_2-x_1}}\)

Plug in the data:

\(\sf{m=\dfrac{8-4}{-4-8}}\\\\\sf{m=\dfrac{4}{-12}\)

Simplify:

\(\sf{m=-\dfrac{4}{12}}\)

\(\sf{m=-\dfrac{1}{3}}\)

Hence, the slope is negative one-third.

Answer:

1/3

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation: because the equation is in the format f(x)= mx+b and mx represents slope and b represents y. 2/9x is the slope so 1/3 is the y intercept (can i have brainliest)

Answer:

y = 15

Step-by-step explanation:

Given: y varies directly with x, x=4 when y=20

To find:  y when x = 3

Solution:

As y varies directly as x, it means that as x increases, y also increases by the same factor.

As y varies directly with x,

\(y=kx\)

Here, k is a constant

As x = 4 when y = 20,

\(20=4k\\k=\frac{20}{4}=5\\\Rightarrow y=5x\)

Put x = 3

\(y= 5(3) = 15\)

There is a Weak positive association between the amount of goals scored and the number of wins a hockey team has. Most of the data points fall between 4 goals scored and 5  number of wins. Causation cannot be established because their relationship was not in a controlled setting.

When if a relationship between two variables is said to be  negative, it is one that does not just necessarily mean that the association is weak. Although though both variables tend to increase in reaction to one another, a weak positive correlation depicts that the relationship is not very strong.

Therefore, even though  the data tells us that there is a weak positive relationship that exist between the two variables, it is vital to know that that correlation does not equal causation.

Answer:

  addition property of equality

Step-by-step explanation:

You want the justification for step 1 in the solution process for -22 - x = 14 + 6x.

No solution process steps are shown, but we can speculate what they might be.

The goal is to separate constant terms and variable terms. This can be done several ways, but generally consists of adding the same thing to both sides of the equation.

Often, you're told to collect the variable terms first. Some prefer to do that so the variable terms are on the left side of the equal sign. Others prefer to do that so the result has a positive coefficient for the variable term. Taking the latter tack, we want to add x (the opposite of -x) to both sides of the equation:

  -22 -x +x = 14 +6x +x . . . . . x added to both sides

  -22 = 14 +7x . . . . . . . simplified

The justification for this step is the addition property of equality. That property allows you to add the same thing to both sides of an equation without changing the values of the variables.

__

Additional comment

Step 2 would be to add -14 to both sides, giving you ...

  -36 = 7x . . . . . . . . add -14; addition property of equality

If you like, you can do both of these additions in one step:

  -22 -x +(x -14) = 14 +6x +(x -14) . . . add(x -14); addition property of equality

  -36 = 7x . . . . . . simplified

Step 3 is to divide by the coefficient of the variable.

  -36/7 = (7x)/7 . . . . division property of equality

  -5 1/7 = x . . . . . . . simplified. This is the solution.

The usual procedure takes 3 steps, so this is called a "3-step equation."

Note that we choose for the variable coefficient to be positive, because we judge arithmetic with positive numbers to be less error-prone. If you collect the variable terms on the left, you get ...

   -7x = 36

so have to divide by -7. This should not be an issue if you're careful with your arithmetic, but many find dealing with negative numbers to be a challenge.

Answer:

216 square feet

Step-by-step explanation:

First we must convert both dimensions to feet. 1 yd = 3 feet

8 yd = 24 feet and 3 yd = 9 feet

We got the yd by multiplying by 3 to get the number of fett.

Area of a rectangle = base * height

24 feet * 9 feet = 216 square feet

In order to define the quantity of which of the two website produces a larger amount of content per single writer, Charlotte thought of:

Charlotte wants to know which website has more content per writer which means that she wants to know which website is more productive with writing.

One way she can do this is to check the average number of posts per writer per website. This would show her which website has a writer that writes more content on average.

Charlotte could also use average number of words per writer. This shows just how much writing the writers in each websites are doing, in terms of words. The website with the higher average words per writer is therefore providing more content.

Answer:

8700kg

Step-by-step explanation:

b = mass of bricks

l = mass of lorry

b+l = total mass = 11600kg

b = 3l  ==>  l = b/3

substitute: b + b/3 = 11600

multiply every term by 3 to get rid of denominator: 3b + b = 34800

simplify and solve:  4b = 34800  ==>  b = 8700

check:  l = 8700/3 = 2900

2900 + 8700 = 11600?  YES
