Which statement best describes the functions represented here?
A.only function p is nonlinear
B. Neither function is nonlinear
C.only function q is nonlinear
D.both functions are nonlinear
Answer:
D
Step-by-step explanation: for p(x), the slope from 0 to 3 is 30, meaning if linear every time x increases by 3, the y value should as well, meaning that six as an x value to be linear should have been 90, but it was not.
For q(x), the slope from 0 to 3 is 90, and following the same thing from above, this means for every 3 units moved on the x, it should increase by 90 units on the y. This means 6 to be linear should have been 200 but instead was 380 making it also nonlinear

Find x. Use law of sine. Round to the nearest tenth.
Answer:
9.5
Step-by-step explanation:
Law of sine:
[tex]\frac{SideXY}{sinZ^{o}} = \frac{SideZY}{sinX^{o}} = \frac{SideXZ}{sinY^{o}}[/tex]
Sum of interior angles = 180°:
∴∠Z° = 180° - 63° - 41°
∠Z° = 76°
∴[tex]\frac{14}{sin76^{o}}[/tex]= [tex]\frac{x}{sin41^{o}}[/tex]
Cross- multiplication is applied:
(x)(sin76°) = (14)(sin41°)
x has to be isolated and made the subject of the equation:
x = [tex]\frac{[(14)(sin41^{o})]}{sin76^{o}}[/tex]
x = 9.466
x = 9.5 (Rounded to the nearest tenth)
An online company is making $60 profit every week. The company owes the bank 300 dollars for the start-up money. How much does the company need to pay the bank and make a profit of 150
Answer:
The company must make $450.
If the company must pay $300, then you will take 300, and since they want to make a profit, which means 1500 dollars more once they pay the 300, the you will add that to 300.
300 + 150 = 450
Now to find how many weeks it will take, you will divide 450 by 60:
450/60 = 7.5
It will take 7 1/2 (or round it to 8)weeks to gain $450, which is enough money to pay the bank $300, and make a profit of $150.

It takes Mrs. Ritts 3 hours to mow her back yard. This is 2 hours less than twice the time it takes her to mow the front yard. Write an equation that will show the time it takes her to mow the front yard. (use x as the variable)
Answer:
5/2 hours or 2 hours and 30 minutes
Step-by-step explanation:
The x represents the time it took Mrs. Ritts to mow the front yard. We don't know this time so put it as a variable. We also know that the time to mow her backyard is equal to 2 times the variable and then minus 2.
Equation: 3 = (2x) - 2
Now we just isolate the x. First, start by adding 2 to both sides.
5 = 2x
Now just divide both sides by 2.
5/2 = x
5/2 as a mixed number would be 2 and 1/2 so that means the time would be 2 and a half hours.

Find the cardinal number for the set.
B = {x|XEN
and 5
Answer:
Step-by-step explanation:
Cardinality of a set refers to the number of elements in the set. There are two types of cardinality: finite and infinite. A set is considered to have finite cardinality if it has a finite number of elements, meaning that the elements can be counted. A set is considered to have infinite cardinality if it has an infinite number of elements and cannot be counted.
In the case of the set B = {x | x ∈ N and x > 5}, the set is comprised of all natural numbers greater than 5. The set of natural numbers is infinite, meaning that there are an infinite number of elements in the set B. As a result, the cardinality of the set B is also considered to be infinite.
The symbol "ℵ0" is used to represent the cardinality of the set of natural numbers, and it is often used to indicate the cardinality of infinite sets with the same size as the set of natural numbers. In this case, we can say that the cardinality of the set B is ℵ0, meaning that the set B has the same size as the set of natural numbers and therefore has infinite cardinality.

The jacket's original price is $65.00. It is on sale for 40% off. You have to pay 5% sales tax. What is the final price for the jacket?
Answer:
To find the final price for the jacket, we need to first calculate the amount of the discount and then add the sales tax.
The amount of the discount is $65.00 * 40% = $26.00. So the price after the discount is $65.00 - $26.00 = $39.00.
The sales tax is $39.00 * 5% = $1.95. So the final price for the jacket is $39.00 + $1.95 = $40.95.
Step-by-step explanation:
Answer:
he final price for the jacket is $40.95.
Step-by-step explanation:
First, let's calculate the discount for the jacket:
Discount = $65.00 * 40% = $26.00
The price of the jacket after the discount is:
$65.00 - $26.00 = $39.00
Next, let's calculate the sales tax:
Sales tax = $39.00 * 5% = $1.95
Finally, let's add the sales tax to the discounted price to find the final price:
Final price = $39.00 + $1.95 = $40.95
So, the final price for the jacket is $40.95.

Answer:
y = 3x
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{1}{3}[/tex] x + 4 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then
y = 3x + c ← is the partial equation
to find c substitute (- 1, - 3 ) into the partial equation
- 3 = 3(- 1) + c = - 3 + c ( add 3 to both sides )
y = 3x + 0 , that is
y = 3x
you deposit $1000 in an account that pays 3.5% annual interest compounded monthly. when is your balance at least $1200? round your answer to nearest hundredth.
The balance will be at least $1200 after 8.18 months, if you deposit $1000 in an account that pays 3.5% annual interest compounded monthly.
What is compound interest?The result of earning interest on a principal amount as well as the accumulated interest from earlier periods is known as compound interest. It occurs when money is reinvested rather being paid out, allowing interest to be generated on the principle and accrued interest over the next month.
The balance of an account with an initial deposit of $1000 earning 3.5% annual interest compounded monthly will reach $1200 after 8.18 months.
To find the time it takes for the balance to reach $1200, we can use the formula for compound interest, A = P[tex](1 + r/n)^{nt}[/tex],
where P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time in years.
In this case, P = 1000, r = 0.035, n = 12 (because the interest is compounded monthly), and t is the unknown variable. We can rearrange the formula to solve for t:
t = (A/P) / (1 + r/n)
Plugging in the values, we get
t = (1200/1000) / (12(1 + 0.035/12))
which simplifies to
t = 8.18 months
Therefore, it will take 8.18 months for the balance of the account to reach $1200.

For each of the following graphs, the two given polygons are similar. Write precisely a single dilation (coordinates of center and coefficient) by which the image (labeled with primed letters) was obtained.
Polygon ABCD was dilated by a scale factor of 2 to create A'B'C'D'.
What is dilation?Dilation is the increase or decrease in the size of a figure by a scale factor of k, thereby creating an image. Resizing an object is accomplished through the transformation of dilation. The objects can be enlarged or shrunk using dilation. The result of this transformation is an image that has the same shape as the original shape. The size of the shape varies, though. A dilation should either stretch or contract the original shape. The term "scale factor" describes this transformation.

Find the surface area of the pyramid. The side lengths of the base are equal.
The surface area of the pyramid is 116.4 sq. ft.
What is surface area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.
For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.
The surface area of the pyramid is calculated by adding the area of all the faces of the pyramid.
The area of the triangle is given as:
A = 1/2 (b)(h)
For the face of the pyramid:
b = 12 and h = 9
Substituting the values we have:
A = 1/2 (12)(9)
A = 54 sq. ft
The pyramid consists of three faces thus,
A = 3(54) = 162 sq ft
For the base of the pyramid:
b = 12 and h = 10.4 ft
A = 1/2(12)(10.4)
A = (6)(10.4)
A = 62.4 sq ft
The surface area of the pyramid is:
SA = 54 + 62.4
SA = 116.4 sq. ft
Hence, the surface area of the pyramid is 116.4 sq. ft.

Line ℓ has equation y=-x+4. Find the distance between ℓ and the point F(-1 7)
Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
To find the distance between a line and a point, we need to find the perpendicular distance from the point to the line. Here's the step-by-step process:
Find the equation of the line perpendicular to ℓ that passes through point F(-1, 7): Since the slope of line ℓ is -1, the slope of the perpendicular line will be the negative reciprocal of -1, which is 1. To find the equation of the line, we need a point and the slope. Point F(-1, 7) will be used, and the slope is 1.
Using the point-slope form of a line, we can write the equation of the perpendicular line passing through point F as: y - 7 = 1(x + 1). Simplifying, we get: y = x + 8.
To find the point of intersection between the two lines, we can substitute the equation of line ℓ into the equation of the perpendicular line:
-x + 4 = x + 8
Solving for x, we get x = 6. Substituting x = 6 into the equation of line ℓ, we get:
y = -6 + 4 = -2
So, the point of intersection between the two lines is (6, -2).
To find the distance between the point F and the line ℓ, we can use the distance formula:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) is the point F(-1, 7) and (x2, y2) is the point of intersection (6, -2).
So, substituting the values into the formula:
distance = √((6 - (-1))^2 + ((-2) - 7)^2) = √((7)^2 + (9)^2) = √(49 + 81) = √(130) = approximately 11.3
Therefore, the distance between the line ℓ and point F is approximately 11.3 units.
