The student will have $6,500 after 15 weeks.
The initial deposit is $5,000 and the weekly automatic deposit is $100. Let x be the total amount of money the student will have after 15 weeks.
Therefore, the equation that represents the total amount of money the student will have is:x = $5,000 + $100(15)
Since the question wants to know the total amount of money the student will have after 15 weeks,
we simply substitute the value of 15 for the weeks in the equation.
x = $5,000 + $100(15)
x = $5,000 + $1,500
x = $6,500
Therefore, the student will have $6,500 after 15 weeks.

What is the image of the point (-9,-6) after a rotation of 90 degrees counterclockwise about the origin?
The image of the point (-9, -6) after a rotation of 90 degrees counterclockwise about the origin is (6, -9).
A point in a 2D plane can be represented by its coordinates (x, y).
A rotation of 90 degrees counterclockwise about the origin can be represented by the transformation matrix:
[cos(90) -sin(90)]
[sin(90) cos(90)]
When we apply this transformation matrix to the point (-9, -6), we get the following:
[cos(90) -sin(90)][-9] = [0 * -9 + (-1) * -6] = 6
[sin(90) cos(90)][-6] = [1 * -9 + 0 * -6] = -9
Therefore, the image of the point (-9, -6) after a rotation of 90 degrees counterclockwise about the origin is (6, -9).

Jerome walks 90 feet from the base of a tree and looks up The ongle from the ground to the top of the free is 33° How tall is the t.ree?
Using Pythagorean theorem, The height of the tree is approximately 47.98 feet.
What does the Pythagorean theorem mean in everyday language?According to Pythagoras' Theorem, the square of a right-angled triangle's hypotenuse side is equal to the sum of the squares of its other two sides. The three sides of this triangle are known as the Perpendicular, Base, and Hypotenuse.
tan(angle) = opposite side / adjacent side
The opposite side is the height of the tree and the adjacent side is the distance from Jerome to the base of the tree (90 feet).
tan(33) = height / 90
height = tan(33) * 90
The height of the tree is approximately 47.98 feet.

How do latitudes and longitudes help in locating a point Class 6?
Latitudes and longitudes help in locating a point by providing a reference system for navigation.
They are used to pinpoint a specific location on the earth’s surface by providing coordinates. These coordinates are measured in degrees and minutes and are written in the form of a pair of numbers. Latitudes are measured in degrees north or south of the equator and are referred to as the lines of latitude. Longitudes are measured in degrees east or west of the prime meridian and are referred to as the lines of longitude. By using the coordinates of a point, the location can be accurately determined. This is especially useful for navigation, as it enables people to determine their position and travel to a specific destination.

Calculate the next four terms!
My brain isnt working, please help
===================================================
Explanation:
The sequence appears to be geometric. Let's test that claim out.
Divide each term by the previous term.
r = term2/term1 = 62500/312500 = 0.2r = term3/term2 = 12500/62500 = 0.2r = term4/term3 = 2500/12500 = 0.2Each time we get the result 0.2, which is the common ratio r. It tells us this sequence is indeed geometric.
To get the next term in a geometric sequence, we multiply the last term 2500 by this common ratio.
term5 = r*term4 = 0.2*2500 = 500Follow similar steps for terms 6 through 8.
term6 = r*term5 = 0.2*500 = 100term7 = r*term6 = 0.2*100 = 20term8 = r*term7 = 0.2*20 = 4Terms 5 through 8 are 500, 100, 20, and 4 in that order.

I’m lost :,)
Answer:
9.) -32 thousand ft per hour
10.) 9/4° per hour
Step-by-step explanation:
9.) To solve this problem, we first need to know the time that the plane landed, which is after 5 hours. Now, we need to find the altitude of the plane a four hours and thirty minutes, which is 16 thousand ft. Lastly, we need to know the formula for rate of change, which is change in y over change in x. Below is the work for how to solve the problem:
change in y / change in x = [tex]\frac{16-0}{4.5-5}[/tex]
[Note: four hours and thirty minutes is equal to 4.5 hours.]
[tex]\frac{16-0}{4.5-5} = \frac{16}{-0.5} =32[/tex]
So, the rate of change from four hours and thirty minutes to when the plane landed is -32 thousand ft per hour.
10.) You did number 10 for the most part, except that the denominator is 8 not 9-0. The reason for this is that is is 8 hours between 6am and 2pm, not 9. This means our final answer is 18/8, or 9/4° per hour.

Trigonometric Function:
In mathematics, trigonometric functions (also called circular functions, trigonometric functions, angular functions) are real functions that relate the angles of a right-angled triangle to the ratio of the lengths of its two sides. They are widely used in all geometry-related sciences such as navigation, solid mechanics, celestial mechanics, and geodesy. They are one of the simplest periodic functions and are often used to study periodic phenomena using Fourier analysis.

The triangles are similar. What is the value of x? enter your answer in the box. X = two right triangles. The larger triangle has the long leg labeled 96, the short leg labeled 28, and the hypotenuse labeled 6 x plus 28. The smaller triangle has the long leg labeled 24, the short leg labeled 7, and the hypotenuse labeled 25.
The value of x is 12.
The triangles which are similar have the same shape and measure of three angles are also same. The only thing that varies is their sides. However, the ratio of the sides of one triangle is equivalent to the ratio of the sides of another triangle, which is called here the scale factor.
By dividing the long sides and short sides, find the scale factor:
96 / 24 = 4
28 / 7 = 4
So, the large triangle is four times bigger than the small one.
Now applying the scale factor to calculate the hypotenuse:
The length of the smaller hypotenuse is 25, a scale that by 4 to get 25 * 4 =100
This means that the larger hypotenuse needs to equal 100 and the hypotenuse is labeled 6x +28:
6x+28 = 100
Subtract 28 from each side:
⇒6x = 72
Divide both sides by 6:
⇒x = 72/6
∴x = 12
So, the value of x is 12.

A diagonal of a rectangle will intersect the same number of squares as the length of the rectangle. The rectangle has a length of 7 squares and a width of 4 squares, so the diagonal will intersect 12 squares.
A diagonal of a rectangle will always intersect the same number of squares as the length of the rectangle. In this case, the rectangle has been outlined on a grid paper with dimensions of 7x4. This means that the length of the rectangle is 7 squares and the width is 4 squares. Therefore, the diagonal of this rectangle will intersect 12 squares in total. This is because the length of the rectangle is greater than the width and so the diagonal must intersect the entire length of the rectangle and all of the squares the width intersects. As a result, the diagonal of this rectangle will intersect 12 squares.
