Answer:
B. 0
Step-by-step explanation:
The line x = -3 is vertical, thus undefined, because there is no y in the equation. The slope that is perpendicular to an undefined one is 0.
x = 3 is a vertical line.
A line perpendicular to x = 3 is a horizontal line.
A horizontal line has slope = 0.
General formula for a straight line
The general formula for a straight line is ‘y=mx+c'.
But in the equation ‘x = -3’, ‘y' isn't present meaning that the line is independent of ‘y' which is true for a line parallel to the ‘y-axis'. This case can be compared to a generic equation ‘x=a' where a is the distance of the parallel line (to y-axis') from the origin.
This line represents a parallel line to the y-axis which is 3 units left side from the origin.
Now about calculating the slope, we can use the formula ‘m = tan ϴ’
where ‘m' is the slope and ‘ϴ’ is the angle of the line with the X-axis.
Here the value of ϴ is 90° as it is parallel to the y-axis. So the line perpendicular to it will surely have ϴ=0°. Which will be parallel to the
x-axis.
Another method of explaining this can be, for ϴ=90°, m=tan(90),
so m= infinity. if the slope of the line parallel to it is ’n', the relation between the slope of two perpendicular lines is ‘[tex]m*n=-1[/tex]’. Putting the value of ‘m=infinity' we get ‘n=0’.
Now for getting n=0 the angle must be O° as tan(0°)=0 which is nothing but a line parallel to the x-axis.
Therefore, the correct answer is option B.0.

Find the lowest value of the data this box -and-whisker ploy represents 12,1315,16
Answer:
12
Step-by-step explanation:
The lowest value is indicated by the dot at the end of the left whisker
That is the lowest value = 12
The lowest value in a box-and-whisker plot is the minimum of the dataset. For the given data set, the lowest value, which is the minimum, is 10.
Explanation:The student is asking us to find the lowest value represented in a box-and-whisker plot. A box-and-whisker plot is a graphical representation of a five-number summary of a dataset: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and the maximum. The lowest value in a box-and-whisker plot is the minimum of the dataset.
To graph a box-and-whisker plot for the given data values, you would first need to arrange the data in ascending order. Then, find the minimum, Q1, median, Q3, and the maximum. The smallest number, which is placed at the leftmost part of the plot, is the minimum, also known as the lowest value of the dataset. For the data set provided (10, 10, 10, 15, 35, 75, 90, 95, 100, 175, 420, 490, 515, 515, 790), the lowest value is 10.

Which equation models the line that passes through points (4, 6) and (−4, 8)
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 7
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 )
To calculate m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (- 4, 8)
m = [tex]\frac{8-6}{-4-4}[/tex] = [tex]\frac{2}{-8}[/tex] = - [tex]\frac{1}{4}[/tex], hence
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 4, 8 ), then
8 = 1 + c ⇒ c = 8 - 1 = 7
y = - [tex]\frac{1}{4}[/tex] x + 7 ← equation of line
A flashlight is projecting onto a wall, as shown below
Answer:
n = 30
Step-by-step explanation:
The triangles share the same angle measures, so they are similar triangles. The side lengths of similar triangles are proportional to each other, so we can set up a proportion and solve for n...
16 is to 20 as 24 is to n
16/20 = 24/n now solve for n by cross multiplying
16n = 480
n = 30 (divide both sides by 16)
We are given that the original triangle and its projection are similar. This means that the corresponding angles of the two triangles are congruent, and the ratios of their side lengths are equal.
We are also given the lengths of two sides of the original triangle: 16 cm for the base and 20 cm for the hypotenuse. We are asked to find the missing length on the projection, which corresponds to the base of the original triangle.
To solve this problem, we can set up a proportion based on the similar triangles. Let x be the missing length on the projection:
(base of original triangle) / (base of projection) = (hypotenuse of original triangle) / (hypotenuse of projection)
Substituting the known values:
16 cm / x = 20 cm / 24 cmCross-multiplying:
16 cm * 24 cm = x * 20 cm384 [tex]cm^2[/tex] = 20x [tex]cm^2[/tex]x = 384 [tex]cm^2[/tex] / 20 [tex]cm^2[/tex]x = 19.2 cmTherefore, the missing length on the projection is 19.2 cm. However, the answer choices are all rounded to one decimal place.
Rounding 19.2 cm to one decimal place gives us 19.0 cm. Therefore, none of the provided options are correct.

Determine the area of each of the following polygons using the area formula you created in part d.
Polygon Area
regular pentagon with apothem of approximately 9 inches and side length of 13 inches
regular octagon with apothem of approximately 5 centimeters and side length of 4 centimeters
regular hexagon with apothem of approximately 6 feet and side length of 7 feet
Answer:
1. The area of regular pentagon = 292.5 inches²
2. The area of the regular octagon = 80 cm²
3. The area of the regular hexagon = 126 feet²
Step-by-step explanation:
∵ The area of any regular polygon = 1/2 × perimeter × apothem
1. Regular pentagon
∵ Regular pentagon has 5 equal sides
∵ The perimeter of the regular pentagon = 5 × side length
∵ S = 13 inches
∴ P = 13 × 5 = 65 inches
∵ apothem = 9 inches
∴ A = 1/2 × 65 × 9 = 292.5 inches²
2. Regular octagon
∵ Regular octagon has 8 equal sides
∵ The perimeter of the regular octagon = 8 × side length
∵ S = 4 cm
∴ P = 4 × 8 = 32 cm
∵ apothem = 5 cm
∴ A = 1/2 × 32 × 5 = 80 cm²
3. Regular hexagon
∵ Regular hexagon has 6 equal sides
∵ The perimeter of the regular hexagon = 6 × side length
∵ S = 7 feet
∴ P = 7 × 6 = 42 feet
∵ apothem = 6 feet
∴ A = 1/2 × 42 × 6 = 126 feet²

1) When it says what percent 14 is of 125( what percent of 125 gives you 14)
Algebraically It's like this
125p=14
2) just solve for p
P=14/125 ( 125 is divided on both sides)
P= 0.112
3) plug in 0.112 for P
125 x 0.112 = 14

. The first stud has already been placed at one end of the wall. How many additional studs are needed, if the last stud will be placed at the other end of the wall? First fill in the blanks on the left side using the ratios shown.
I believe it is 45 studs to the end of the wall
Answer:
Step-by-step explanation:
First, convert 20 yds to 60 ft. and then from 60 ft to 720 in.
Use the formula for the nth term of an arithmetic sequence:
l = a + (n-1)d:
Here l = 720 ft, and a = 0. The common difference, d, is 16 in. Our task is to determine how many studs are needed.
Substituting the knowns, we get 720 = 0 + (n - 1)(16), which simplifies to:
720 = (n-1)(16).
Divide both sides by 16 to isolate (n-1): 45 = n - 1.
Adding 1 to both sides results in 46 = n.
46 studs total are needed; if the worker has already placed the first stud, then 45 additional studs are needed.
Solve the equation.

Otis had a salad for $4.50, a sandwich for $6.25, and a drink at his favorite restaurant. The tax for the entire meal was $0.54. What was the price of the drink?
Answer:
Price of the drink = $1.25
Step-by-step explanation:
4.5% * ( $4.5 + $6.25 + drink) = $0.54
4.5/100 * ( $4.5 + $6.25 + drink) = $0.54
0.045 * ( $4.5 + $6.25 + drink) = $0.54
0.045/0.045 * ( $4.5 + $6.25 + drink) = $0.54/0.045
( $4.5 + $6.25 + drink) = $12
10.75 + drink = $12
drink = $12 - $10.75
drink = $1.25
The price of the drink is $1.25
How to determine the price of the drink?The given parameters are:
Tax amount = $0.54
Salad = $4.50
Sandwich = $6.25
Let the price of the drink be x.
Given that the sales tax is 4.5%, we have:
4.5% * ( $4.5 + $6.25 + x) = $0.54
Divide both sides by 4.5%
( $4.5 + $6.25 + x) = $12
Evaluate the sum
$10.75 + x= $12
Subtract $10.75 from both sides
x = $1.25
Hence, the price of the drink is $1.25

Replace t with 1 through 4 and solve then add them together:
6^(1-1) = 6^0 = 1
6^(2-1) = 6^1 = 6
6^(3-1) = 6^2 = 36
6^(4-1) = 6^3 = 216
Sum = 1 + 6 + 36 +216 = 259
Answer: The required sum is 259.
Step-by-step explanation: We are given to find the sum of the following geometric series :
[tex]\sum_{i=1}^{4}6^{i-1}.[/tex]
The given geometric series can be written as :
[tex]0+6+6^2+6^3.[/tex]
We know that
the sum of a geometric series up to n terms with first term a and common ration r is given by
[tex]S=\dfrac{a(r^n-1)}{r-1}.[/tex]
in the given series, we have
[tex]a=1,~~r=\dfrac{6}{1}=\dfrac{6^2}{6}=\dfrac{6^3}{6^2}=6.[/tex]
Therefore, the sum up to 4 terms will be
[tex]S_4=\dfrac{a(r^4-1)}{r-1}=\dfrac{1(6^4-1)}{6-1}=\dfrac{1296-1}{5}=\dfrac{1295}{5}=259.[/tex]
Thus, the required sum is 259.
