The range of the function modelling the number of hours it takes clara to earn p dollars is;
A set of all real numbers from 3 to 8
Minimum dollars she earns working; p_min = $36.75
Maximum dollars she earns working; p_max = $98
number of hours it takes her to earn p dollars is given by;
t(p) = p/12.25
Now, range of a function is a set of all possible output values.
Thus, t(36.75) = 36.75/12.25
t(36.75) = 3 hours
Similarly;
t(98) = 98/12.25
t(98) = 8 hours
Since minimum time is now 3 hours and maximum time is now 8 hours, then the range of the function is;
3 ≤ t ≤ 8 which is a set of all real numbers from 3 to 8

d.
Area of the given Circle as the function of its diameter πd²/4
What is circle?A Circle is the 2D shape which is measured in the terms of its radius.
Given that Area, radius and diameter of the given Circle is a , r and d respectively.
Area of Circle (A) = π X radius²
radius = diameter/2
Therefore replacing radius by diameter we get,

A solid right pyramid has a regular hexagonal base with an area of 7.4 units2. The pyramid has a height of 6 units.
What is the volume of the pyramid?
11.1 units3
14.8 units3
22.2 units3
44.4 units3
Answer:
Option B. 14.8 units³ is the answer.
Step-by-step explanation:
It is given in the question A solid right pyramid which has a regular hexagonal base with area = 7.4 unit²
Height of the pyramid = 6 units.
We have to calculate the volume of the pyramid.
Since volume of the pyramid = (1/3)×Area of the base × height
Volume = (1/3)×7.4×6 = 7.4 × 2 = 14.8 units³
Therefore option B. 14.8 units³ is the answer.
It should be noted that the volume of the pyramid will be 14.8 unit³.
How to calculate the volume of the pyramidFrom the information given, the solid right pyramid has a regular hexagonal base with an area of 7.4 units².
The height of the pyramid is also 6 units. Therefore, the volume of the pyramid will be:
= 1/3 × Area of the base × height
= 1/3 × 7.4 × 6
= 14.8 units³
In conclusion, the volume of the pyramid is 14.8 unit³.

If vx = 7.60 units and vy = -6.60 units, determine the magnitude of v⃗ .
Answer:
|v| = 10.06 units
Step-by-step explanation:
It is given that,
The x component of the vector is, [tex]v_x=7.6\ units[/tex]
The y component of the vector is, [tex]v_y=-6.6\ units[/tex]
We need to find the magnitude of vector v. The magnitude of any vector is calculated as :
[tex]|v|=\sqrt{v_x^2+v_y^2}[/tex]
[tex]|v|=\sqrt{(7.6)^2+(-6.6)^2}[/tex]
|v| = 10.06 units
So, the magnitude of vector v is 10.06 units. Hence, this is the required solution.

Which trigonometric function would be used to find the length of this triangle's hypotenuse?
The cosine function is used to find the length of the hypotenuse of a triangle by utilizing the Pythagorean theorem.
The trigonometric function used to find the length of the hypotenuse of a triangle is the cosine function. In a right triangle, the cosine function is defined as the ratio between the length of the adjacent side to the length of the hypotenuse.
To find the length of the hypotenuse, you can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the hypotenuse.
For example, if the lengths of the shorter sides are 9 blocks and 5 blocks, then the length of the hypotenuse would be √(9² + 5²) = √(81 + 25) = √106 = 10.3 blocks.

Enter your answers, in simplest form, in the boxes to complete the coordinate proof.
Point Q is the midpoint of DE , so the coordinates of point Q are (a, b).
Point R is the midpoint of FE , so the coordinates of point R are ([ ], b).
In ΔDEF , the length of the base, DF , is [ ], and the height is 2b, so its area is [ ].
In ΔQRP , the length of the base, QR , is [ ], and the height is b, so its area is ab.
Comparing the expressions for the areas proves that the area of the triangle created by joining the midpoints of an isosceles triangle is one-fourth the area of the triangle.
Thanks in advance. Please explain.
Answer:
#4) 1/2(ab); #5) 3a, 4a, 4ab, 2a
Step-by-step explanation:
#4) Take the top triangle. The height will be the difference in the y-coordinates of J and M:
b-0 = b
The base of the triangle would be the difference in the x-coordinates of J and K:
a-0 = a
The area is given by the formula A=1/2bh, where b is the base and h is the height; substituting our height and base, we have
A=1/2(b)(a) = 1/2(ab)
#5) To find the midpoint of a section, we add together the x-coordinates and divide by to, and add together the y-coordinates and divide by 2.
The endpoints of FE are (4a, 0) and (2a, 2b). This makes R:
[tex](\frac{2a+4a}{2},\frac{2b+0}{2})\\\\=(\frac{6a}{2},\frac{2b}{2})\\\\=(3a, b)[/tex]
The length of DF can be found by subtracting the x-coordinates:
4a-0 = 4a
The area is then found by multiplying 1/2 by the base and the height:
A=1/2(4a)(2b) = 1/2(8ab) = 4ab
The length of QR can be found by subtracting the x-coordinates:
3a-a = 2a
an artist is cutting pieces of ribbon to use in a project. Each piece he cuts measures 7/8 inch. The aritst cuts off 5 pieces. How many total inches of ribbon has he cut off?
The artist has cut off a total of 4 and 3/8 inches of ribbon for his project by multiplying the length of one piece (7/8 inch) by the total number of pieces cut (5).
Explanation:The question involves a straightforward arithmetic operation of multiplication. Each piece of ribbon the artist cuts measures 7/8 inch, and he cuts off 5 pieces in total. To find the total length of ribbon cut off, we multiply the length of one piece (7/8 inch) by the number of pieces cut (5).
Calculation: \(\frac{7}{8} \text{ inch} \times 5 = \frac{35}{8} \text{ inches} = 4 \frac{3}{8} \text{ inches}\)
Therefore, the artist has cut off a total of 4 and 3/8 inches of ribbon for his project. This example demonstrates a practical application of multiplication in a real-world context, specifically within arts and crafts projects.

[tex]x+3y=22~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\2x-y=2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
From equation (ii), we have
[tex]2x-y=2\\\\\Rightarrow y=2x-2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]
Substituting the value of y from equation (iii) in equation (i), we get
[tex]x+3(2x-2)=22\\\\\Rightarrow x+6x-6=22\\\\\Rightarrow 7x=22+6\\\\\Rightarrow 7x=28\\\\\Rightarrow x=\dfrac{28}{7}\\\\\Rightarrow x=4.[/tex]
From equation (i), we get
[tex]4+3y=22\\\\\Rightarrow 3y=22-4\\\\\Rightarrow 3y=18\\\\\Rightarrowy=\dfrac{18}{3}\\\\\Rightarrow y=6.[/tex]
Thus, the required solution is (x, y) = (4, 6).

Mike and Kate plan to save money for their wedding over a 20 month period. They will need to save $8,000 to help pay for the wedding. They set aside the same amount each month. After a year they saved $4,000. Mike and Kate know they must adjust their plan in order to meet their goal, so they came up with the following options: Option A: Stay with saving the same amount they've been saving each month but postpone the wedding 2 months. Option B: Increase the amount of money they save each month by $80 from what they've been saving. Which of the following is a true statement? a. Only option A will allow them to meet their goal. b. Only option B will allow them to meet their goal. c. Both options A and B will allow them to meet their goal. d. Neither option A nor option B will allow them to meet their goal
To meet their goal of saving $8,000 for their wedding, Mike and Kate need to adjust their plan. Increasing the amount they save each month by $80 (Option B) will allow them to reach their goal.
Explanation:To determine which option will allow Mike and Kate to meet their goal of saving $8,000 for their wedding, we need to analyze the information given. They saved $4,000 in the first year, which means they saved $4,000 in 12 months. To reach their goal, they need to save an additional $4,000 in 8 months.
Option A: If they stay with saving the same amount they've been saving each month, they will save the same amount each month for the remaining 8 months. Therefore, they will not reach their goal of $8,000.
Option B: If they increase the amount they save each month by $80, they will be saving $80 more each month for the remaining 8 months. This will result in them saving an additional $640 ($80 x 8 months) and reaching their goal of $8,000.
Therefore, the correct answer is Option B - Only option B will allow them to meet their goal.

7(2+5v)=3v+14 can anyone help???
The solution to the equation is v = 0.
We have,
To solve the equation 7(2 + 5v) = 3v + 14, we can simplify and isolate the variable v.
Expanding the left side of the equation:
7(2 + 5v) = 14 + 35v
Now we have:
14 + 35v = 3v + 14
Next, we can combine like terms:
35v - 3v = 14 - 14
32v = 0
To solve for v, we divide both sides of the equation by 32:
v = 0/32
v = 0
Therefore,
The solution to the equation is v = 0.
