Identify the matrix transformation of ΔRST, which has coordinates R(−1, 1),S(2, −2), and T(−3, 3), for 90° rotation, clockwise. Then identify the correct vertices of the image.
Answer:
( 0 1 ) ( -1 2 -3) (1 -2 3)
= R' (1, 1), S' (-2, -2), T' (3, 3)
( -1 0 ) ( 1 -2 3) (1 -2 3)
Step-by-step explanation:
Write the x - coordinates of RST in row 1 and the y - coordinates in row 2 of the matrix.
(-1 2 -3)
(1 -2 3)
R S T
For a 90° rotation, clockwise, multiply the matrix by (0 1)
(-1 0)
Then you get your answer.

45. A population of llamas is growing at a constant yearly rate of 6%. At what rate is the llama population
growing per month? Please assume all months are equally sized and that there are 12 of these per year.
Round to the nearest tenth of a percent.
Answer:
0.1%
Step-by-step explanation:
6% = 6/100 or 0.06
0.06 divided by 12 is 0.005
0.005 or 5/100 = 0.05%
rounded to the nearest tenth is 0.1%
Find the percent change:
$350 to $400
Answer:
14.29% increase
Hope this helps!
Step-by-step explanation:
The formula for this would be:
New value - Old value
Then divide the answer by the old value
Finally multiply it by 100
So it should be $400 - $350 which is $50
Then $50 ÷ $400 which is 0.125
Finally do 0.125 × 100 which is 12.5
So there has been a 12.5% increase
Hope this helps and/or makes sense!
A company rents out 11 food booths and 22 game booths at the county fair. The fee for a food booth is $125 plus $6 per day. The fee for a game booth is $80 plus $10 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
$3135 + $286d
Step-by-step explanation:
Given that:
Food booth = 11
Game booth = 22
Let number of days = d
Food booth rent = ($125 + 6d) * 11
Game booth rent = ($80 + 10d) * 22
Food booth = $1375 + $66d
Game booth = $1760 + $220d
Amount company is paid :
Food booth rent + game booth rent
($1375 + $66d) + ($1760 + $220d)
$(1375 + 1760) + $(66d + 220d)
$3135 + $286d

Solve the linear graph
y=3x+7
points to plot:
(0, 7) (1, 10) (2, 13) (4, 19)
For the given equation of the graph, the slope is 3 and the y-intercept is 7.
An algebraic equation known as a linear equation depicts a straight line on a graph. This equation has one as the greatest power of the variable or variables at play. In other words, no exponentiation or other mathematical action is performed on the variables in a linear equation.
The general equation of the straight line is,
y = mx + c
Here, m is the slope and c is the y-intercept.
Compare the given equation with the general equation of the line,
y = mx + c
y = 3x + 7
Therefore, the slope is 3 and the y-intercept is 7.

An equilateral triangle with side length 1 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
Answer:
1/2 cm
Step-by-step explanation:
the area of the triangle is √3/4cm^2.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Here, given that,
An equilateral triangle with side length 1 cm .
we know,
area of An equilateral triangle
=√3/4×side²
so, the area of the triangle = √3/4×1
=√3/4 cm^2

What is 12 = 1 + a/1 -a?
Answer:
There is no solution
Step-by-step explanation:
There are no values of (a) that make the equation true.
Answer:
a = 11/13
Step-by-step explanation:
Multiply both sides by 1 - a
12(1 - a) = 1 + a
= 12 - 12a = 1 + a
Subtract 12 from both sides
= -12a = -11 + a
Subtract a from both side
-13a = -11
Divide by -13 each side
-13a/13 = -11/-13
= a = 11/13
