Here we have an arithmetic sequence with a common difference of 6, so the recursive formula is:

Tₙ = Tₙ₋₁ + 6

Where T₁ = 4.

Here we have the following sequence:

4, 10, 16, 22, ...

This seems to be an arithmetic sequence, to check this, we need to take the difference between consecutive terms and see if this is constant.

10 - 4 = 6

16 - 10 = 6

22 - 16 = 6

So yes, this is an arithmetic sequence and the common difference is 6, this means that each term is 6 more than the previous one, so the recursive formula is:

Tₙ = Tₙ₋₁ + 6

The average rate of change of a function f(x) from x1 to x2 is given by:

In this case we need the first three seconds so x1=0 and x2=3.

Calculate the values of the function at x=0 and x=3 to get:

f(0)=150 and f(3)=0.

Substitute these values into the formula for average rate of change:

Hence the avearage rate of change of the function for the first three seconds is -50.

Note that the negative sign shows that the function is decreasing in the time interval (first three seconds).

We can determine the strength of a correlation by A. The more closely two variables follow the general trend, the stronger the correlation (which may be positive or negative).

Correlation is a statistical term that reflects how closely two or more variables are related to one another. Correlation is measured on a scale of -1 to +1, with 0 indicating a negative correlation and > 0 indicating a positive correlation. A value of 0 implies that there is no association.

A positive correlation is a two-variable association in which both variables move in lockstep. A positive correlation exists when one variable declines while the other increases, or when one variable increases while the other falls. The number one represents a perfect positive association.

If there is an increase or decrease in one variable results in increase or decrease in the other then there is correlation. If the value of correlation is close to either extremities (+1 or +1) then there is strong correlation.

The number line graph is the number line showing x < 61/5, as shown below:

The interval notation of the solution is (- ∞, 61/5) or (- ∞, 12.2)

The function is

1) x-intercept(s)

The x-intercepts refer to the points on which the function intercepts with the x-axis, in other words, when y=h(x)=0

So, given that condition, we get

Therefore, there are two x-intercepts, and those are the points

2) y-intercepts

The y-intercepts happen when x=0. So,

So, there is only one y-intercept and it's on the point (0,-8)

3) Vertex

The general equation of a parabola is

There is another way to express the same function, which is called the 'vertex form':

Summing up the information in the four previous steps, we get

The value of the composite function g(f(x)) is 1 / 3 (81x² - 216x + 144) + 4

A composite function is a function that depends on another function. In a composite function, the output of one function becomes the input.

Therefore, let's solve the function as follows;

f(x) = 1 / 3 x² + 4

g(x) = 9x - 12

The value of g(f(x)) can be found as follows:

To find g(f(x)) we have to substitute the f(x) in g(x).

Therefore,

g(f(x)) = 1 / 3 (9x - 12)² + 4

(9x - 12)(9x - 12) = 81x² - 108x - 108x + 144

(9x - 12)(9x - 12) = 81x² - 216x + 144

Therefore,

g(f(x)) = 1 / 3 (81x² - 216x + 144) + 4

ANSWER

$3100

EXPLANATION

Sally deposits $2500 at 8% interest for 3 years.

We want to find the amount she can withdraw at the end of the period.

To know this, we have to first find the interest.

Simple Interest is given as:

Therefore:

Therefore, after 3 years the interest will be $600.

The amount she can withdraw after this period is therefore the sum of the principal and the interest:

$2500 + $600 = $3100

She can withdraw $3100 at the end of the period.

Parallelogram. Option A is correct

In order to determine the best name for a quadrilateral with the given vertices, we will find the measure of the distance AB, BC, CD, and AD using the distance formula as shown;

For the measure of AB with coordinates A(5,-2), B(2,2);

For the measure of BC with coordinates B(2,2) and C(1, -5)

For the measure of CD with coordinates C(1,-5), and D(-2,-1);

For the measure of AD with coordinates A(5, -2), and D(-2,-1);

For the slopes;

Check if the length AB is perpendicular to AD

For the slope of AD

Since AB is not perpendicular to AD, hence the quadrilateral is not a rectangle and also not a square or rhombus since all the sides are not equal.

From the given distances, you can see that opposite sides are equal (AB = CD and BC = AD ), hence the best name for a quadrilateral is a parallelogram.

Given the matrix

its determinant is computed as follows:

ad - cb

In this case, the matrix is

and its determinant is

2(-5) - 4(-1) = -10 - (-4) = -10 + 4 = -6

Side-Angle-Side Theorem states that triangles are congruent if any pair of corresponding sides and their included angle are congruent.

How do we know that their sides are congruent, by similarity ratios, means a ratio of the lengths of the sides to see if they have the same ratio or scale factor:

Then, since their sides are congruent and they have the same angle, they are congruent by SAS.

Answer

x = 35°

y = 145°

z = 25°

Explanation

We are told to solve for x, y and z.

Considering the first triangle with angles 55°, x° and the right angle (90°).

The sum of angles in a triangle is 180°.

So,

x° + 55° + 90° = 180° (Sum of angles in a triangle is 180°)

x° + 145° = 180°

x = 180° - 145° = 35°

Then, we can solve for y. Angles x and y are on the same straight line, and the sum of angles on a straight line is 180°

x° + y° = 180°

35° + y° = 180°

y° = 180° - 35°

y° = 145°

We can then solve for z°. The big triangle has angles (55° + 10°), z° and the right angle (90°).

The sum of angles in a triangle is 180°.

So,

55° + 10° + z° + 90° = 180°

z° + 155° = 180°

z = 180° - 155°

z° = 25°

Recall that given points (a,b) and (c,d) the slope of the line that joins this points is given by

Lets call the next point (-1,y) . So using this, we have
