Triangle RST was transformed using the rule (x, y) → (–x, –y). The vertices of the triangles are shown.
R (1, 1)
S (3, 1)
T (1, 6) R' (–1, –1)
S' (–3, –1)
T' (–1, –6)
Triangle RST was transformed by using the rule (x,y) → (-x,-y) and the transformation is described by the transformation of 180° rotation about the origin.
Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Here we have transformed the triangle using the rotation method.
Rotation is the geometric transformation that revolves each point in a shape a predetermined number of degrees around that point. When the number of degrees is positive, the shape spins counterclockwise; when the number of degrees is negative, it rotates clockwise. The following is a broad description of how rotation about the origin can be transformed.
(X,Y) to rotate 90° (-y, x)180° rotation (x, y) (-x,-y)To rotate (x,y) 270° (y, -x)Here the points change to R'(-1,-1) , S'(-3,-1) and T'(-1,-6).
A 180° rotation about the origin will be the transformation.
The triangles RST and R'S'T' are first plotted on a graph. The graph is provided for your reference below.
The original triangle RST, which was in quadrant 1, has changed to triangle R'S'T', which is in quadrant 3, as shown in the graph. The rotation around the origin is 180° from quadrant 1 to quadrant 3.

Julián just retired, and has $800,000 to invest. A very safe Certificate of Deposit (CD) account pays 2.5%, while a riskier bond fund pays 5% in interest. Julián figures he needs $36,000 a year in interest to live on. How much should he invest in each account to make enough interest while minimizing his risk?
An equation is formed of two equal expressions. Julian should invest $160,000 in CD and $640,000 in Bond.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the amount invested in CD be represented by x, while the amount invested in bond be represented by y. The total amount that Julian had is,
x + y = 800,000
x = 800,000 - y
The interest that Julian needs in a year is $36,000. Therefore, the total interest should be,
0.025x + 0.05y = 36000
0.025(800,000 - y) + 0.05y = 36000
20,000 - 0.025y + 0.05y =36,000
0.025y = 16,000
y = $640,000
Substitute the value of y
x + y = 800,000
x = $160,000
Hence, Julian should invest $160,000 in CD and $640,000 in Bond.

Un constructor tiene un predio, por lo que está considerando que los terrenos sean rectangulares con un perímetro de 64 metros.
Based on the perimeter of the rectangle, and the adjustments to make the plot a square, the sides are 13m and 19m.
What are the sides of the plot?The perimeter is:
2(L + W) = 64
L + W = 32
The adjustment to make the plot a square would mean that both sides can be equal:
L + 3 = W - 3
L = W - 6
Substituting in the original formula gives:
L + W = 32
W - 6 + W = 32
2W = 38
W = 19 m
L would be:
L + W = 32
L + 19 = 32
L = 13m

c. The distance between the base of the ladder and the base of the tree.
d. The distance between the base of the tree and the spot where the zip line is anchored in the ground.
Using the trigonometric ratios, the measures are:

What are the Trigonometric Ratios?The ratios of trigonometry that can be used to solve a right triangle are:
sin ∅ = opp/hyp
cos ∅ = adj/hyp
tan ∅ = opp/adj.
a. Find h using the sin ∅ = opp/hyp:
sin 75 = opp/hyp = h/40
h = (sin 75)(40) = 38.6
Find z using the sin ∅ = opp/hyp
sin 10 = opp/hyp = 38.6/z
z = 38.6/sin 10
z = 222.5 ft. (length of the zip line)
b. Height of the tree = h = 38.6 ft.
c. Using sin ∅ = opp/hyp, find b (distance between the base of the ladder and the base of the tree):
sin 15 = b/40
b = (sin 15)(40)
b = 10.4 ft
d. Using sin ∅ = opp/hyp, find B as shown in the image:

Answer:
x = 0 or x = 1
Step-by-step explanation:
f(x) = |x| - 4
g(x) = x³ - 4
f(x) = g(x)
|x| - 4 = x³ - 4
Add 4 to both sides.
|x| = x³
x = x³ or -x = x³
x³ - x = 0 or x³ + x = 0
x(x² - 1) = or x(x² + 1) = 0
x = 0 or x + 1 = 0 or x - 1 = 0
x = 0 or x = -1 or x = 1
x = -1 does not work, so we discard that solution.
Answer: x = 0 or x = 1
Answer:
values of x: x = 1 and x = 0
Step-by-step explanation:
Given:
f(x)= |x| - 4g(x) = x³ - 4Want: x - values when f(x) = g(x)
f(x) = g(x) → |x| - 4 = x³ - 4positive interval x ≥ 0negative interval x < 0|x| - 4 = x³ - 4, the 4 cancel out on both sides
|x| = x³
|x| - x³ = x³ - x³
|x| - x³ = 0, x ≥ 0
-x - x³ = 0, x < 0
x = 0
x = -1, x ≥ 0
x = 1
x = 0, x < 0
The intersections are x = 0 and x = 1 and no solution

Simple interest on a bank loan can be calculated by multiplying the principal times the interest rate times the time. In the formula I = p r t, what does I stand for? a. time c. principal b. interest rate d. simple interest Please select the best answer from the choices provided
Answer:
simple interest
Step-by-step explanation:
this is because r is interest rate, p is principal, and t is time
Answer:
simple interest
Step-by-step explanation:
Simple interest rate is defined as: I = p * r * t. So you're taking the principle amount (initial amount loaned) and multiply it by the interest rate. This gives you the interest rate in a year (usually, depends on time unit of t). Generally speaking, it gives you the interest over a specific amount of time. Now multiply it by the amount of time that's passed. So you're just calculating the total amount of interest. So the I stands for the simple interest.
A real estate agent is showing homes to a prospective buyer. There are 10 homes in the desired price range listed in the area. The buyer wants to visit only 3 of them. a. In how many ways could the 3 homes be chosen if the order of visiting is considered? b. In how many ways could the 3 homes be chosen if the order of visiting is not important?
There are 720 ways that the 3 homes could be chosen if the order of visiting is considered. There are 120 ways that the 3 homes could be chosen if the order of visiting is not important.
What is permutation?A permutation is the arrangement or ordering of a finite set of an element.
From the information given:
If there are 10 homes in the desired price range listed in the area:
Then:
n = 10 and r = 3So, the number of ways of choosing 3 out of 10 (without replacement) and arranging is:
[tex]\mathbf{^nP_r= \dfrac{n!}{(n-r)!}}[/tex]
[tex]\mathbf{^nP_r= \dfrac{10!}{(10-3)!}}[/tex]
[tex]\mathbf{^nP_r= \dfrac{10\times 9\times 8 \times 7!}{(7)!}}[/tex]
= 720 ways
Now, the number of ways of choosing 3 out of 10 if the order of visiting is not important is the combination of the elements and it can be computed as:
[tex]\mathbf{^nC_r= \dfrac{n!}{(n-r)!r!}}[/tex]
[tex]\mathbf{^{10}C_3= \dfrac{10!}{(10-3)!3!}}[/tex]
[tex]\mathbf{\implies \dfrac{10\times 8\times 9 \times 7!}{(7)! \times 3\times 2}}[/tex]

The model for the height of the balloon captured from the ground with a balloon launcher can be represented by the function… how long will it take for the balloon to hit the ground after it’s launched?
Answer:
2 seconds
Step-by-step explanation:
To find the time it takes for the balloon to reach the ground, you need to set the equation equal to 0. This is because the ground technically has a height of 0.
h(t) = -16² + 128t <----- Original expression
0 = -16² + 128t <----- Plug 0 in for h(t)
16² = 128t <----- Add 16² to both sides
256 = 128t <----- Solve 16²
2 = t <----- Divide both sides by 128
Therefore, if t = 2, it will take the balloon 2 seconds to reach the ground.
==========================================================
Explanation:
The balloon is on the ground when the height is zero.
Replace h with 0 and solve for t.
[tex]h(t) = -16t^2 + 128t\\\\0 = -16t^2 + 128t\\\\-16t^2 + 128t = 0\\\\-16t(t - 8) = 0\\\\-16t = 0 \ \text{ or } \ t-8 = 0\\\\t = 0/(-16) \ \text{ or } \ t = 0+8\\\\t = 0 \ \text{ or } \ t = 8\\\\[/tex]
Ignore t = 0 because this is when the balloon is initially on the ground. In other words, the balloon starts on the ground, so it makes sense that t = 0 leads to h = 0.
The other solution t = 8 is what we're after. The balloon touches the ground again at the 8 second mark. This is the length of time the balloon is in the air.
