a_4= 216

1) Given that we have the first term and the Recursive Formula, let's find the fourth term of that Sequence

2) Let's find the second, the third to find the fourth since a Recursive formula depends on the prior term.

3) Hence, the sequence is 8, 24, 72, 216 and the fourth term is 216

Given the equation;

You are to calculate the value of y. This is as shown below;

First collect the like terms;

Evaaluate the expression an find y;

Divide both sides by -6;

Hence the value of y is -5

The start figure has two chords in the circle.

By theorem of internal division of chords it follows:

Hence the value of x is 12.

Given that,

The perimeter of a rectangle is 60.

The perimeter is generally defined as the length of the outline of the shape.

So, in rectangle having four sides, the perimeter would be sum of all the sides.

Length1 + length2 + length3 + length4 = perimeter

Here, length1 and length3 are equal, that are the lengths (y),

Similarly,

Length2 and length4 are equal, that is width (x).

Hence, the equation becomes,

x + y + x + y = perimeter

or

2x + 2y = 60

or

2 (x + y) = 60

Hence, the first two options are correct.

we get that:

its current value is $11091.25

t = n(p-c)

t=100(11.75 - 1.75)

t = 100(10)

t=$1000

total profit received = $1000

The function for an exponential growth/decay is given as follows;

Where,

Observe that from the equation provided, the rate is 1.015. This means there is a growth. If there was a decay(decrease), the rate would be less than 1 because, the formula then would be;

ANSWER:

Therefore, the population of elephants is INCREASING.

You have the following equation:

M = 2rt³ - 3rx

In order to solve the previous equation for x, proceed as follow:

M = 2rt³ - 3rx subtract 2rt³ both sides

M - 2rt³ = -3rx divide by -3r both sides

(M - 2rt³)/(-3r) = x simplify left side

-M/3r + 2/3 t³ = x

78 divide by 14

First, divide the numbers

78/14 = 5.57

5.57 lies between 5 and 6

To make the graph we need to make a table with different pairs of angles and radius.

We can start with θ = 0, and calculate the radius for different values of θ. (π/6, π/3, π/4 and so on. Then, you can join the points.

The equation for radius will be:

Then, in the line of θ = 0, you draw a point in the fourth circle.

Then, we get the following table of values:

θ r

04.00

π/63.72

π/43.36

π/32.83

π/20.00

Note that we can't evaluate angles whose cosine is negative (angles in quadrants 2 and 3) since we would be trying to calculate the square root of a negative number, which does not exist among real numbers. Then, we will evaluate angles in the first quadrant (already done) and the 4th quadrant.

θ r

-π/63.72

-π/43.36

-π/32.83

-π/20.00

In the last table we use negative angles, they can be "translated" to positive:

-π/6= π/6

-π/4= 7π/4

-π/3= 5π/3

-π/2= 3π/2

Now, we can draw the points:

Joining the points:

We have to solve the expression:

We have to find a common denominator for the fractions and then solve it.

We can start by simplifying the fractions that can be simplified, like 2/6.

Then, the common denominator between 14 and 3 is 14*3=42, so we end with:

Answer: 41/42

Given:

A rectangular pool with the following measures,

Perimeter

Length = x + 8

Width = x

Let's determine the measure of its dimensions:

Let's now determine its dimensions,

Length = x + 8 = 7 + 8 = 15 ft.

Width = x = 7 ft.

Therefore, the dimension of the rectangular pool is Length = 15 ft. and Width =7 ft.

Answer:

The number of units that will give the maximum profit is;

The maximum possible profit is;

Explanation:

Given that the weekly revenue for a product is given by ;

and the weekly cost is ;

Recall that

Profit = Revenue - Cost

Using graph to derive the maximum point on the function;

Therefore, the maximum point is at the point;

So;

The number of units that will give the maximum profit is;

The maximum possible profit is;

We will have the following:

First, we construct the exponential decay function, that is:

Now, we will determine the population after 6 years:

So, the population after 6 years will be of approximately 37491 people-

1/3 is a rational number, which written as a decimal is an infinite period decimal.

We are asked to correct the following statements:

A. "The hypotenuse is the longest side of the right triangle" The statement is true.

B. "The Pythagorean theorem applies to all triangles". The statement is false. The Pythagorean theorem applies to RIGHT triangles.

C. "The hypotenuse is always adjacent to the 90° angle". The statement is false. The hypotenuse is opposite to the 90° angle.

D. "The Pythagorean theorem states that 2a + 2b - 2c". The statement is false. The Pythagorean theorem states that:

E. "The logs, a and b, will always be adjacent to the 90° angle". The statement is true, since a and b represent the adjacent sides of the 90 degrees angle.

F.

y = 2

The given equation is 4y

Divide both sides of the equation by 4

y = 2

Also, since we are asked to use our number sense, we can find what we will multiply by 4 to give 8

Since 4 x 2 = 8, then y = 2

Answer:

An equation that can be used to model the number of dollars, y, Miguel saves in x weeks is;

The slope of the equation in the context is the amount of money Miguel saves in the bank account each week. So, Miguel saves $50 each week.

The y-intercept of the equation in the context is the amount of money Miguel initially have in the bank account. So, the initial amount of money in the bank account is $100.

Explanation:

Given that Miguel saves the same amount of money into a bank account each week.

Let y represent the amount of money in the account after x weeks;

After 3 weeks, the bank account contained $250;

After 10 weeks the bank account contained $600;

Solving for m and b;

subtract the first equation from the second.

substituting the value of m into the first equation;

Therefore, an equation that can be used to model the number of dollars, y, Miguel saves in x weeks is;

From the equation above, the slope m of the equation is;

and the y-intercept b of the equation is;

The slope of the equation in the context is the amount of money Miguel saves in the bank account each week. So, Miguel saves $50 each week.

The y-intercept of the equation in the context is the amount of money Miguel initially have in the bank account. So, the initial amount of money in the bank account is $100.

We have a quadrilateral ABCD, where we know that AB || DC.

The other condition for the quadrilateral to be a parallelogram is that the other 2 sides of the parallelogram are congruent.

The other two sides are AC and BD, so the other condition needed is that AC and BD are congruent.

Answer: AC and BD are congruent.

The best cluster is Las Vegas, which has a percentage of 78% that is linearly close to 77%, the percentage of the whole population of the United States.

Las Vegas

Solution

For this case we know that the total of students are 396 so we can do this:

x + y = 396

Where:

x= number of girls

y = number of boys

Then we have the following condition:

4x = 7y

Then solving for x we got:

x = 7/4 y

Replacing in the first equation we got:

7/4 y + y = 396

11/4 y= 396

y= 396*4/11 = 144

And x= 7/4 * 144 = 252

Then the answer would be:

252 girls and 144 boys

ANSWER

Not a right triangle

EXPLANATION

In a right triangle, the hypotenuse is always the longest side. If these are the side lengths of a right triangle, the sides would be,

The Pythagorean theorem must be true for any right triangle,

Let's see if it is indeed true,

If the Pytagorean theorem is nort true, then this is not a right triangle
