please help im very very desperate
Answer:
Exponential
Step-by-step explanation:
If it were quadratic, y-axis would fall and rise in points, so its not quadratic.
If it were linear, it would have a pattern with a rise/over formula, and it doesn't go in a pattern, so the only answer left is: Exponential.
Answer:
Exponential

The sales tax rate on a new vehicle is 6% if the vehicle is 8,000 then how much will be charged for sales tax
Answer:
The tax on the car equals $480, based on a 6% rate.
Step-by-step explanation:
Giving the following information:
Tax rate (t)= 6% = 0.06
Purchase price= $8,000
To calculate the tax (T), we need to use the following formula:
Tax= tax rate*purchase price
Tax= 0.06*8,000
Tax= $480
The tax on the car equals $480, based on a 6% rate.
The factors of the quadratic function g(x) are (5x – 1) and (x + 4). What are the solutions to the equation g(x) = 0?
Answer:
The solutions to the equation are [tex]x = \frac{1}{5}[/tex] and [tex]x = -4[/tex]
Step-by-step explanation:
The factors of the quadratic function g(x) are (5x – 1) and (x + 4).
This means that:
[tex]g(x) = 0[/tex]
[tex](5x - 1)(x + 4) = 0[/tex]
So
[tex]5x - 1 = 0[/tex]
[tex]5x = 1[/tex]
[tex]x = \frac{1}{5}[/tex]
And
[tex]x + 4 = 0[/tex]
[tex]x = -4[/tex]
The solutions to the equation are [tex]x = \frac{1}{5}[/tex] and [tex]x = -4[/tex]

1. The points ( − 4, − 4), ( − 4, 4), (4, 4), and (4, − 4) form a square on a coordinate plane. How long is a side length of the square
Answer:
Length of one side is 8 units
Step-by-step explanation:
Given
The centre of this square is positioned at the origin as visible form the four co-ordinates
All the four co-ordinates are such that they are 4 units along the x-axis and 4 units along the y-axis.
Let us take the following two co-ordinates - (4,4),(4,−4). The X value for these two co-ordinate points is 4 and the Y values are such that one point has y = 4 and the other has y = -4 i.e 8 units in between.
Thus, length of one side is 8 units.

What is the difference between the area of the larger circle in the area of the smaller circle leave your answer in terms of pi
Answer:
Area= π(R^2-r^2)
Step-by-step explanation:
Although I can't find the attached file
Let the radius of the large circle be R
And the radius of the small circle be r
Area of large circle is
Area= πR^2
Area of small circle is
Area= πr^2
The difference is
Area= πR^2- πr^2
Area= π(R^2-r^2)

A window washer cleaned 38 windows in 2 hours. At this rate, how many windows did he clean in 7 hours?
plz help
Answer:
133 windows in 7 hours
Step-by-step explanation:
38 divided by 2 and you get 19
19 x 7 = 133
Answer:
133 windows
Step-by-step explanation:
First, you would want to find how many windows he can clean in 1 hour.
You know that 38 windows = 2 hours.
To do this, divide both sides by 2 (to get 1 hour). You will get 19 windows = 1 hour.
Now to find 7 hours, multiply both sides of 19 windows = 1 hour by 7 (to get 7 hours). You will get 133 windows cleaned in 7 hours.
The roof of a gazebo is a regular octagonal pyramid. If the base of the pyramid has sides of 0.5 meters and the slant height of the roof is 1.9 meters, find the area of the roof. (roof is lateral surface area)
Answer:
The area of the roof is 3.80 m².
Step-by-step explanation:
The lateral surface area of an octagonal pyramid is given by:
[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}})[/tex] (1)
Where:
s: is the length of the base edge = 0.5 m
h: is the height
We can find the height from the slant height (S = 1.9 m):
[tex] S = \sqrt{h^{2} + 1.457s^{2}} [/tex] (2)
By solving equation (2) for "h" we have:
[tex] h = \sqrt{S^{2} - 1.457s^{2}} = \sqrt{(1.9)^{2} - 1.457(0.5)^{2}} = 1.80 m [/tex]
Now, we can calculate the area of the roof (equation 1):
[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}}) = 2*0.5(\sqrt{4(1.80)^{2} + 5.828(0.5)^{2}}) = 3.80 m^{2}[/tex]
Therefore, the area of the roof is 3.80 m².

A picture that measures 7 inches
by 7 inches is being framed.
The area of the picture with
frame is 81 square inches.
What is the width of the frame?
Answer:
The width of the frame is 2 inches
Step-by-step explanation:
The given dimensions of the picture = 7 inches by 7 inches
The area of the picture, A₁ = 7 in. × 7 in. = 49 in.²
The area of the given picture and the frame, A₂ = 81 square inches
Let 'w' represent the width of the frame and whereby the picture is a square, we have;
The area of the picture with the frame, A₂ = 81 in.² = (7 + w) × (7 + w)
A₂ = 81 = (7 + w) × (7 + w) = 49 + 14·w + w²
49 + 14·w + w² - 81 = 0
w² + 14·w - 32 = 0
(x + 16)·(x - 2) = 0
∴ x = -16 or x = 2
Given that 'x' is a natural number, we have;
The width of the frame, x = 2 inches.

The size of a cell is typically found by capturing an image under a microscope then
using software to measure its diameter. Two cells are measured using this method:
Cell M: 7.65 x 10-3 centimeters
Cell N: 9.1 x 10-4 centimeters
What's the difference between the diameters of the two cells? Express your answer
using scientific notation.
Answer:
The difference is 6.74 * 10^-3 centimeters
Step-by-step explanation:
Firstly, we need to write the numbers as they would occur normally
we have this as;
7.65 * 10^-3 = 0.00765
9.1 * 10^-4 = 0.00091
So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number
we have this as;
0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters
