Dilations: Triangle RST with vertices R(-5,1), S(-3,4), and T(2,-1): k=2
Answer:R’ (-10,2) S’(-6,8) T’(4,-2)
Step-by-step explanation:
Did it in class
After dilation of ΔRST with the given scale factor we have vertices of ΔR'S'T' as R'(-10, 2), S'(-6, 8) and T'(4, -2).
Given that, ΔRST with vertices R(-5,1), S(-3,4), and T(2,-1).
What is a dilation?Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.
Given, scale factor is k=2.
So, with using scale factor
R(-5,1)→2(-5, 1)= R'(-10, 2)
S(-3,4)→2(-3,4)=S'(-6, 8)
T(2,-1)→2(2,-1)=T'(4, -2)
Therefore, after dilation of ΔRST with the given scale factor we have vertices of ΔR'S'T' as R'(-10, 2), S'(-6, 8) and T'(4, -2).

Answer:
4
Step-by-step explanation:
Dilation centered at the origin multiplies each individual coordinate by the scale factor. Considering the x-coordinates of W and W', we have ...
scale factor = Wx'/Wx = -12/-3 = 4
The dilation scale factor is 4.
The shoe store’s clerks are paid on commission. If the clerk receives a 12% commission on total purchase amounts before tax is applied, how much would the commission be for Isaac’s purchase with and without a coupon? (2 points)
plss show work I will mark brainliest
Answer:
a) 37 + 42 =79
=7/100 x 79
=553/100
=5.53
Isaac's total bill = 79 + 5.53 = $84.53
b) 25/100 x 79
= 19.75
= 79 - 19.75
= $59.25 (before tax)
7/100 x 59.25
= 414.75/100
= 4.15
= 59.25 + 4.15
= $63.4 (after adding tax)
First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.

water flows into a reservoir at a rate of 1500+7t^2 gallons/hour. Since there is a tiny hole in the reservoir, the water leaks out at a rate of 4t+t^2 gallons/hour. What is the net change in the amount of water in the reservoir over the time interval of [1,5]
9514 1404 393
Answer:
6200 gallons
Step-by-step explanation:
The rate of change of volume is the difference between the inflow rate and the outflow rate.
v'(t) = (1500 +7t^2) -(4t +t^2) = 6t^2 -4t +1500
The change in volume over the time interval of interest is the integral of this expression over that interval:
[tex]\displaystyle\Delta V=\int_1^5{(6t^2-4t+1500)}\,dt=\left.(2t^3-2t^2+1500t)\right|^5_1\\\\=2(5^3-1^3)-2(5^2-1^2)+1500(5-1) = 2\cdot124-2\cdot24+1500\cdot4\\\\\boxed{\Delta V=6200\qquad\text{gallons}}[/tex]
The amount of water in the reservoir increases by 6200 gallons over the time interval.

At a university, 60% of the students who apply. Of the students the university accepts, 25% actually enroll If 2000 students apply, how many actually enroll?
Answer:
300 students are enrolled.
Step-by-step explanation:
As the university accepts 60% of the students who apply.
As 2000 students apply, it means that:
2000 × 60% ⇒ 2000 × 0.6 = 1200 students are accepted
Out of these 1200, 25% enrolled
1200 × 25% ⇒ 1200 × 0.25 = 300 students are enrolled
Therefore, 300 students are enrolled.
