Line WY is dilated to create line W'Y' using point Q as the center of dilation. What is the scale factor? Given that QY' = 4.125, what is QY?
Answer:
1.2.75
2.1.5
Step-by-step explanation:
I just did it
The scale factor is determined by the ratio of the lengths of corresponding sides of two similar figures. To find QY, divide QY' by the scale factor.
Explanation:The scale factor is the ratio of the lengths of corresponding sides of two similar figures. In this case, line WY and line W'Y' are similar figures, and the scale factor is determined by the ratio of their lengths. The scale factor can be calculated by dividing the length of W'Y' by the length of WY. Given that QY' = 4.125, the scale factor can be determined by dividing QY' by QY. So, the scale factor is 4.125/QY. To solve for QY, divide QY' by the scale factor: QY = QY'/scale factor. Therefore, QY = 4.125/(4.125/QY) = (4.125*QY)/4.125 = QY.

Point A has coordinate A(3, 2). The point is rotated 180° clockwise around the origin. Find the coordinates of point A’. A’(2, 3) A’(–3, –2) A’(–2, –3) A’(–2, 3)
Answer:
A' (-3,-2)
Step-by-step explanation:
When rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. To rotate a figure 180 degrees, you apply the rule (x, y) → (-x, -y). Start by using a coordinate grid with coordinates for each vertex of the figure. The center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. Write down the original coordinates of the shape you are going to rotate. Then, apply the rule. For example, coordinate (3, 2) becomes (-3, -2). Another example would be, coordinate (-4, -2) becoming (4, 2).
(-3,-2) this is your answer

What is the volume of a 14 in diameter pipe that’s 2156 long?
Answer:
Step-by-step explanation:
given that diameter of the pipe = 14 inches
radius = 7 inches
Length =2156 inches
Pipe is in the form of a cylinder
Volume of cylinder = pi r^2 h
where r = radius and h = l = 2156
We have to substitute the values of r and h.
Let us take pi as 22/7
= 22/7 (7)(7)(2156)
Cancel out 7 and multiply the remaining 22 ,7 and 2156
=332024 cubic inches
is -5^2 equal to (-5)^2?
A. Yes, because they both equal -25
B. Yes, because they both equal -10
C. Yes, because they both equal 25
D. No, because -5^2 equals -25 and (-5)^2 equals 25
The correct answer is:
D. No, because [tex]\(-5^2\)[/tex] equals -25 and [tex]\((-5)^2\)[/tex] equals 25.
To evaluate the expression [tex]\( -5^2 \)[/tex] and [tex]\( (-5)^2 \)[/tex], we need to understand the order of operations.
According to the order of operations (PEMDAS/BODMAS), exponentiation takes precedence over negation.
So, [tex]\( -5^2 \)[/tex] means [tex]\( -(5^2) \)[/tex], which equals -25.
On the other hand, [tex]\( (-5)^2 \)[/tex] means [tex]\( (-5) \times (-5) \)[/tex], which equals 25.
Therefore, [tex]\( -5^2 \)[/tex] is not equal to [tex]\( (-5)^2 \)[/tex].
The correct answer is option D.
please help me find h(6)
To find H(6) for the function H(x) = 5(x - 6), substitute 6 for x, resulting in H(6) = 5(6 - 6) = 5(0) = 0.
The question asks for the evaluation of H(6) when H(x) = 5(x - 6). To find H(6), we simply substitute 6 in place of x in the function and calculate the result.
H(6) = 5(6 - 6)
Calculating the expression within the parentheses:
6 - 6 = 0
Now multiply by 5:
5 times 0 = 0
Therefore, H(6) = 0.

The answer you are looking for is M = -18.
To find this answer, you first distribute 9 into the parenthesis (m + 4). Once you've distributed, you should be left with 9m + 36 = 7m. Next, you subtract 9m from both sides. This will give you 36 = -2m. Finally, divide both sides by 2. Thus giving you a final answer of M = -18.

Hey there!
To solve this, we will first replace x with 5 anytime we see it in the equation.
f(5) = 2^5
Now, we simplify 2^5.
The base is 2 and the exponent is 5 in this case.
The exponent is the number of times you multiply the base by itself. In oour case:
2 x 2 x 2 x 2 x 2 = 32
f(5) = 32

erica takes a cab to meet her grandmother at a musuem. her grandmother wiill giive her a ride hime. she only has$25.05 to spend and a cab cost.$3 plus $0.35 per mile. what are rhe maximum number if miles that Erica may travel before she has to walk the rest of the way to the museum?
The maximum miles that she can travel 63 miles before she can walk.
Final answer:
By setting up an equation that accounts for the cab's base fare and the additional per mile charge, we can determine that Erica can afford to travel a maximum of 63 miles in the cab before exceeding her budget of $25.05.
Explanation:
To determine the maximum number of miles Erica can travel in a cab without exceeding her budget of $25.05, we can create an equation where the cost of the cab is equal to the base fare plus the per mile charge times the number of miles (mileage). We know the base fare is $3 and the per mile charge is $0.35. Let's denote the number of miles Erica can travel as 'm'.
The cost equation would be: Cost = Base Fare + (Per Mile Charge × Mileage)
This gives us: $25.05 = $3 + ($0.35 × m)
Subtracting the base fare from both sides gives us: $22.05 = $0.35 × m
Dividing by the per mile charge yields: m = $22.05 / $0.35
Calculating this, we get: m = 63 miles
Therefore, Erica can travel a maximum of 63 miles in the cab before she would need to walk the rest of the way to the museum to stay within her budget.

evaluate f(x) when x = -10
So, when x = -10.
If you notice, -10 is NOT in the domain (the domain is (-3,13))
so, there is no solution.
Answer: -24
Step-by-step explanation:
Step one :
For the first equation
Given that x=-10
F(x) =2x-4 if 3<x<10
x exists in this domain
Substituting x in the equation we have
F(-10)=2(-10)-4
F(-10)= -20-4
F(-10)=-24
Step two :
For the second equation
Given that x=-10
F(x) =x²-+3 if 10<=x<13
x does not exist in this domain
0.86 divide 5 -0.3 multiply 0.5
Answer:
The solution is 0.022.
Step-by-step explanation:
Given that,
[tex]\dfrac{0.86}{5}-0.3\times0.5[/tex]
We need to solve the equation
Using PEMDAS rule
On dividing 0.86 by 5
[tex]0.172-0.3\times0.5[/tex]
On multiply 0.3 from 0.5
[tex]0.172-0.15[/tex]
On subtract 0.15 from 0.172
[tex]0.022[/tex]
Hence, The solution is 0.022.
if prices increase at a monthly rate of 1.4% by what percentage do they increase in a year?
Prices increase by approximately 18.17% in a year if they rise at a monthly rate of 1.4%.
The given monthly rate of 1.4% can be represented as 1.014 in decimal form (1 + 0.014).
To calculate the total increase over a year, we need to compound this monthly rate for 12 months since there are 12 months in a year. We can use the formula for compound interest to find the overall increase:[tex]\[A = P(1 + r)^n\][/tex]
Where:
[tex]\(A\)[/tex] = the final amount after [tex]\(n\)[/tex] periods (in this case, a year),
[tex]\(P\)[/tex] = the initial price (100% or 1 in decimal form, as it's the starting point),
[tex]\(r\)[/tex] = the monthly rate in decimal form (1.4% or 0.014), and
[tex]\(n\)[/tex] = the number of periods (12 months).
Plugging in the values:
[tex]\[A = 1 \times (1 + 0.014)^{12}\][/tex]
[tex]\[A = 1 \times 1.1771\][/tex]
[tex]\[A \approx 1.1771\][/tex]
The final amount [tex](\(A\))[/tex] represents the price increase over the year. To express this as a percentage, we subtract 1 from [tex]\(A\)[/tex] and then multiply by 100:
[tex]\[Price \, Increase \, Percentage = (A - 1) \times 100\][/tex]
[tex]\[Price \, Increase \, Percentage = (1.1771 - 1) \times 100\][/tex]
[tex]\[Price \, Increase \, Percentage \approx 18.17\%\][/tex]
Therefore, prices increase by approximately 18.17% in a year if they rise at a monthly rate of 1.4%.
