Write an equation in slope-intercept form thats perpendicular to the given line and goes thru the point.
1. y=-3x + 4 (6,-2)
2. -2x -8y = 16 (4,5)
3.. x+y= 2 (8,5)
(PLS HELP ME I NEED THE ANSWER RIGHT NOW ITS URGENT)
Answer:
steps below
Step-by-step explanation:
1. y=-3x + 4 (6,-2)
y' slope: 1/3 (perpendicular)
y' = mx + b
b = y' - mx = -2 - (1/3) x 6 = -4
equation: y' = 1/3 x - 4
2. -2x -8y = 16 (4,5)
8y = -2x - 16 y = -1/4 x - 2
perpendicular line slope: 4
b = y - mx = 5 - 4 x 4 = - 11
equation: y = 4x - 11
3. x+y= 2 (8,5)
y = -x + 2 slope: -1
perpendicular slope: 1
b = y - mx = 5 - 1 x 8 = -3
equation: y = x -3
write the equation of the line shown in the graph in slope intercept form
Answer:
y= 4x +3
Step-by-step explanation:
slope= rise over run
y-intercept = where the line hits the y axis
find the amplitude.
f(x)=2.3cos(4x)
Answer:
As cosine returns a value between -1 and 1, the amplitude will simply be the coefficient of the cosine function. In this case it's 2.3, which tells us that the amplitude is also 2.3
The book shelf was bought at a wholesale price of \$147.00$147.00dollar sign, 147, point, 00, and Gabriela's Furniture Store marks up all furniture by 60\%60%60, percent. At what price should the manager sell the book shelf?
Answer:
$235.20
Step-by-step explanation:
Calculation for At what price should the manager sell the book shelf
First step is to calculate the price increase using this formula
Price increase=Marks up percentage*Wholesale price
Let plug in the formula
Price increase=60%*$147.00
Price increase=$88.20
Now let calculate the price that the manager should sell the book shelf using this formula
Book shelf Price=Wholesale price+Price increase
Let plug in the formula
Book shelf Price=$147.00+$88.20
Book shelf Price=$235.20
Therefore the price that the manager should sell the book shelf is $235.20

Cynthia invests some money in a bank which pays
5% compound interest per year.
She wants it to be worth over £8000 at the end of 3 years.
What is the smallest amount, to the nearest pound, she can invest?
Answer: £6910.7
Step-by-step explanation:
Given
Rate [tex]R=5\ \%[/tex]
Amount [tex]A=[/tex]£[tex]8000[/tex]
Time [tex]T=3\ years[/tex]
In compound interest, the Amount is given by
[tex]A=P[1+\frac{R}{100}]^T[/tex]
[tex]8000=P[1+\frac{5}{100}]^3[/tex]
[tex]P=\dfrac{8000}{1.1576}[/tex]
[tex]P=[/tex]£[tex]6910.7[/tex]

Answer:
DJ = 48
Step-by-step explanation:
In triangle CDE, point J is the centroid.
Length of median DH = 72
By the property of the centroid of a triangle,
"Centroid of a triangle divides the medians in the ratio of 2 : 1"
By this property, length of DJ = [tex]\frac{2}{(2+1)}(DH)[/tex]
= [tex]\frac{2}{3}(72)[/tex]
= 48 units
Therefore, length of DJ = 48 units

In the diagram, the length of segment QV is 15 units.
Line m is a perpendicular bisector of line segment S Q. It intersects line segment S Q at point R. Line m also contains points T and V. Line segment T S is 3 x + 2. Line segment S V is 4 x minus 1.
What is the length of segment TQ?
Answer:
TQ=14
Step-by-step explanation:
Given:
QV=15
Since the figure is a kite because SR=QR and TV is perpendicular to SQ:
SV=QV and ST=TQ
so:
4x-1=15
x=4
ST=3x+2=14
TQ=14

Answer:
11
Step-by-step explanation:
Following the order as set out in PEMDAS ( parenthesis, exponents, multiplication, division, addition, subtraction )
evaluating parenthesis gives
2 + [tex]3^{4}[/tex] ÷ 9 ← evaluate exponent
= 2 + 81 ÷ 9 ← evaluate division
= 2 + 9 ← evaluate addition
= 11
Mr. Brown made 5 trips to the sushi bar. On his first trip, he got 14 pieces of sushi. On his second trip, he got 12 pieces of sushi. On his third trip, he got 22 pieces of sushi. On his fourth trip he got 8 pieces of sushi. On his final trip, he got 24 pieces of sushi. What was the average (use the mean) number of pieces of sushi he got on each trip to the sushi bar?
Answer: 16 pieces.
Step-by-step explanation:
Suppose that we have a set with N numbers
{x₁, x₂, x₃, ..., xₙ}
The mean of this set is calculated as:
M = (x₁ + x₂ + x₃ + ... + xₙ)/N
In this case, our set is:
{14, 12, 22, 8, 24}
So we have N = 5.
The mean of this set will be:
M = (14 + 12 + 22 + 8 + 24)/5 = 16
The average/mean number of pieces of sushi he got on each trip is 16 pieces.
10 less than a number squared is 71

what is the slope of the line that passes through the point (-1,-10) and (-1,-2). answer needs to be in simplest form
Answer: m = undefined
Step-by-step explanation:
-2-(-10) = 8
-1-(-1) = 0
m = 8/0
Which is an undefined slope
Answer:
The slope is undefined
Step-by-step explanation:
Plug in the points to the formula for slope (Formula Found Below). You would get (-2 + 10)/(-1 + 1), which simplifies to 8/0. Anything divided by 0 is undefined, which means that the slope is undefined.
Furthermore, you could also tell this simply by the points given. If two points on a line have the same x - coordinate, it means that the slope is undefined and that the line formed by the points isn't a function.
Formula for Slope:
[tex]\frac{y1 - y2}{x1 - x2}[/tex]
Usable with 2 points of the line given ((x1, y1) and (x2, y2))
Express "17 billion" in scientific
notation.
Answer:
The scientific notation is [tex]1.7\times 10^{10}[/tex].
Step-by-step explanation:
Consider the provided information.
We need to express 17 billion in scientific notation.
17 billion is: 17,000,000,000
We split the given number into a coefficient and a power of 10.
Move the decimal point of the given number till the coefficient of the given number is greater than 1 and less than 10 and write the power of 10 equal to the number of steps the decimal point was moved.
17 billion in scientific notation = [tex]1.7\times 10^{10}[/tex].
Hence, the required answer is [tex]1.7\times 10^{10}[/tex].
