James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.
Answer: $339
Step-by-step explanation:
Given
The total length of the journey is 10 miles
fixed pledges are $300
variable pledges are $13 per mile
Point slope equation form is
[tex]\Rightarrow y=mx+c[/tex]
Here the total charge corresponds to y and miles walked corresponds to x
So, we can write
[tex]T=13\times m+300[/tex]
where,
[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]
for 3 miles distance
[tex]\Rightarrow T=3\times 13+300=\$339[/tex]
The measure of an angle is 34.7°. What is the measure of its supplementary angle?
Answer:
Let the supplementary angle be x.
x+34.7°=180
or, x=180-34.7°
or, x=145.30°
:. x=145.30°

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)

C E

Kristine wants to do hardwood flooring for her room. A floor plan of the room (in feet) is shown how much hardwood flooring does she need.
Answer:
The answer is "[tex]116 \ ft^2[/tex] "
Step-by-step explanation:
Please find the complete question in the attachment file.
Calculating the sides of the room:
[tex]8\times 8=64\\\\12\times 2=24 \\\\2\times 6=12 \\\\4 \times 4=16\\\\[/tex]
adding the value of the side area:
[tex]\to 64+24+12+16=116[/tex]
1. y = 6 x+8
2. y = 23 x
3. y = -x+ 5
4. y = 3 4 x - 212
5. y = 1,5 x + 11

List the sign of each trig function for the given angle.
3(x + 1) - 2x = -6 what’s the answer??
Answer:
x=−9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+1)−2x=−6
(3)(x)+(3)(1)+−2x=−6(Distribute)
3x+3+−2x=−6
(3x+−2x)+(3)=−6(Combine Like Terms)
x+3=−6
x+3=−6
Step 2: Subtract 3 from both sides.
x+3−3=−6−3
x=−9
Find the area of the parallelogram.
Answer:
36 ft^2
Step-by-step explanation:
I) Find dimensions:
The base is 9 feet, and the height is 4 feet.
(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)
II) Find area:
Area = base x height
A = B x H
36 = 9 x 4
III) Find unit:
Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.
The admission free at a small is $ 1.50 for children and $ 4.00 for adults on a certain day $ 5,050 is collected if 1,000 adults attended the fair write and slove a linear equation to find the number of children that attended.
Answer:
c=children
a=adult
total amount=1.5c+4a
5050=1.5c+4*1000
1.5c=1050
c=700 childrens
Step-by-step explanation:
An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 6.
Event B: The sum is not divisible by 4.

Answer:
640 units squared
Step-by-step explanation:
First, the formula of a trapezoid is (a + b) x 2 divided by h
So, 40 + 24 = 64
64 x 20 = 1280
and 1280/2 = 640
Hope this helps!
Can someone help me with this ?
Answer:
The angle of 1 would be 63°
Step-by-step explanation:
the line is 180°, so if 3 is 117° then 2 is the same as 3. Making 1 and 4 the remaining degrees of the 180.
can someone please help me with this.
Answer:a neither perpendicular nor parallel.
Step-by-step explanation:
Parallel would have the same slope, meaning same constant with x and perpendicular would be like 1/2x and -2

1. A rectangle has side lengths of 3x2 + 5x - 1 and -7x+1. Which of the following expressions represents the area of the rectangle?
a. 3x²-21
b. 3x² - 35x-1
c. -21x³ - 38x²- 2x - 1
d. -21x³ - 32x² + 12x - 1

How many degrees is arc PQ?
Answer:
Step-by-step explanation:
Arc PQ is 60°
Answer:
[tex]\boxed {\boxed {\sf Arc \ { PQ } = \ 60 \ degrees}}[/tex]
Step-by-step explanation:
The angle that forms arc PQ is a central angle, because the angle's vertex is at the center of the circle.
According to arc-angle relationships, the measure of a central angle is equal to the arc.
Since the central angle is equal to 60 degrees, arc PQ is also equal to 60 degrees.
For our safety, it is important that drivers recognize a stop sign immediately. Stop signs are made with exact side and angle measurements to form a regular octagon. They are red so they are easy to see. The three lines drawn below are straight lines. Lines a and b are parallel. a) The stop sign is a regular octagon, so the measure of ∠F must be 67.5°.
