graph the image of triangle abc after dilation with the scale factor of 3 centered at the origin?
Answer:
A' = (0,0)
B' = (6,-12)
C' = (-12,-12)
Step-by-step explanation:
According to the Question,
Let's label the corner points of the triangle A,B,C starting at the origin and moving clockwise(ForDiagram Please Find in Attachment)A = (0,0) , B = (2,-4) , C = (-4,-4)
Dilating with a scale factor 3 means we multiply each coordinate of each point by the value 3A = (0,0) becomes A' = (0,0). No change happens. This point is fixed
B = (2,-4) becomes B' = (6,-12). This point does move
C = (-4,-4) becomes C' = (-12,-12). This moves as well
So all you need to do from here is draw triangle A'B'C'.
Note ⇒
the lengths of triangle A'B'C' are Thrice as long as their counterparts on triangle ABC. Consequently, this means the perimeter of A'B'C' is Thrice as long as the perimeter of ABC. Also, triangle A'B'C's area is Nine times larger than the area of triangle ABC.Please help i need it NOW! NO LINKS!!!!!!

Jimmy earns $500 a week selling shoes. He also earns 8% commission on all of his shoe sales. Last week, he sold $1,540 worth shoes. How much money did Jimmy earn last week?
show work
To determine the amount Jimmy made last week, you will need to calculate the commission he made on his sales and add the $500 to that amount.
Here is the math equation showing this:
($1540 x 0.08) + $500 = $623.20
Jimmy made $623.20 last week.
When the dragons have lost their most recent game, fans buy 200 tickets. For each consecutive win the dragons have, the number of tickets fans buy increases by a factor of 1.1 Which expression gives then number of tickets fans buy after 4 consecutive wins?
Answer:
Y(4) = 200(1.1)^4
Step-by-step explanation:
Given that :
Number of tickets purchased before consecutive wins = 200
For each consecutive win, ticket purchased increases by a factor of 1.1
Number of tickets after 4 wins
This scenario describes an exponential relation :
Where increase is factor based and not a certain number :
Hence,
Number of tickets, Y= Initial number of ticket * growth factor^number of wins
Hence, we have
Y(n) = 200(1.1)^n
Y(4) = 200(1.1)^4 = 292.82

95-3^4=14
Step-by-step explanation:
3^4=81
95-81=14
Part A: 176
Part B: First, I did is multiple 3 to the common denominator by 4 times with the same number and that would give you a positive number of 81, then I combined 81 with 95 and your solution is 176.
Step-by-step explanation:
Part A:

This is urgent!!!
Answer:
1/8
Step-by-step explanation:
( 2^-1 / 2^0) ^3
First simplify inside the parentheses
We know that a^b / a^c = a^(b-c)
2^(-1-0) = 2^-1
( 2^-1 ) ^3
Then we know that a power to a power is
a^b^c = a^(b*c)
2^(-1 *3)
2^ -3
Then a negative exponent makes it a fraction
a^ -b = 1/a^b
1 /2^3

Answer:
A = 20.25 sq units
Step-by-step explanation:
to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it
it appears the segment is 4.5 units so you would square that to get the area
A = 4.5²
A = 20.25

d the volume of the entire figure by adding the volumes of the separate
Answer:
Total Volume = 190 m³
Step-by-step explanation:
Volume of the entire figure = L (Area 1 + Area 2)
where L = 10 m
Area 1 (blue prism) = 4 x 3 = 12 m²
Area 2 (brown prism = 1 x 7 = 7 m²
plugin values into the formula:
Volume of the entire figure = L (Area 1 + Area 2)
= 10 (12 + 7)
= 120 m³ + 70 m³
= 190 m³

What is the slope of the line that passes through the points (26, 7) and (-39, 12)?
Answer:
-1/13
Step-by-step explanation:
The slope of a line is calculated as rise/run.
The rise is the difference in y-values, and the run is the difference in x values
slope= y₂ - y₁/x₂ - x₁
let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)
slope= (12 - 7)/ (-39 -26)
= 5/-65
reduce the fraction to get -1/13
Green River State Park had 312,684 visitors in one summer. Blue Sky State Park had 441,902 visitors.
1. How many fewer visitors did Green River State Park have than Blue Sky State Park? 2. Ashlee said that both state parks had a total of 753,586 visitors. Is Ashlee correct? Explain your reasoning.
Answer:
1. 129,218 fewer vistors than Blue Sku State Park
2. Ashley is not correct, since 441902 + 312684 is 754,586; not 753,586. She made a mistake on the thousands place, which she probably added one extra on accident.
Step-by-step explanation:
Oki, subtract for question one:
441902 - 312684 = 129218
Add for two:
441902 + 312684 = 754586
For problem, number two; I recommend writing it in your own words instead of copying off mines.

A laptop has a listed price of $891.99 before tax. If the sales tax rate is 9.25%, find the total cost of the laptop with sales tax included.
Round your answer to the nearest cent, as necessary.
Please explain to me.
Answer:
$974.50
Step-by-step explanation:
The sales tax is 0.0925($891.99), or $82.51. We need only add this amount to the listed price ($891.99) to find the total cost with sales tax included:
$891.99
+ 82.51
--------------
$974.50
An alternative approach would be to multiply the listed price by 1.0925:
1.0925($891.99) = $974.50
Here the '1' refers to the listed price and the '0.0925' to the sales tax.

the slope is 2.5
(from x=0 to x=2 it goes up by 5)
-2 is the intercept with the y-Axis
the general formula is:
y = m*x + b
where m is the slope and b the intercept

Answer:
LM = 8 cm
Step-by-step explanation:
LM = KN = x + 7
NM = KL = x + 7 + NQ = x + 7 + 2 = x + 9
KN×NM = 80
(x+7)(x+9) = 80
x² + 7x + 9x + 63 = 80
x² + 16x + 63 = 80
x² + 16x - 17 = 0
solution of a quadratic equation
x = (-b ± sqrt(b² - 4ac))/(2a)
a=1
b=16
c=-17
(-16 ± sqrt(256 + 4×17))/2 = (-16 ± sqrt(256+68))/2 =
= (-16 ± sqrt(324))/2 = (-16 ± 18)/2
x1 = (-16 + 18)/2 = 2/2 = 1
x2 = (-16 - 18)/2 = -34/2 = -17
x2 as negative value is no valid solution for a side length.
so, only x1 remand as solution.
=> x=1, LM = KN = 1+7 = 8, NM = KL = 1+9 = 10

What is the area❓ No links or troll answers you’ll be reported
Answer:
103
Step-by-step explanation:
Find the area of the rectangle on the top
A = 7*13 = 91
Now find the area of the rectangle on the bottom
13 - (5+5) = 3
11-7 = 4
The dimensions of the bottom rectangle are 3 by 4
A = 3*4 = 12
The total area is 91+12 = 103

find the other x-intercept for the parabola defined by this equation y=2x2+3-2
Answer:
( [tex]\frac{1}{2}[/tex], 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
2x² + 3x - 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = + 3
The factors are + 4 and - 1
Use these factors to split the x- term
2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term
(x + 2)(2x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
The x- intercepts are (- 2, 0 ), ( [tex]\frac{1}{2}[/tex], 0 )

What is the measure of ∠4?
Answer:
80 degrees
Step-by-step explanation:
angle 1 is equal to 100 because of the law of exterior angles. And since andgle 1 and 2 make 180 degrees we can subtract 80 from 100 and we get the measure of angle 2. Angle 2 and 4 are the same becasue of the law of adjacent angles.
