Answer:
46% of Xander's friends prefer to stay home on Friday nights.
Step-by-step explanation:
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
As given
[tex]\frac{23}{50}\ of\ Zanders\ friends\ prefer\ to\ stay\ home\ on\ Friday\ night.[/tex]
i.e
Zanders friends prefer to stay home on Friday night = 23
Total numbers of Zanders friends are 50.
Part value = 23
Total value = 50
Put in the formula
[tex]Percentage = \frac{23\times 100}{50}[/tex]
[tex]Percentage = \frac{2300}{50}[/tex]
Percentage = 46%
Therefore 46% of Xander's friends prefer to stay home on Friday nights.

Function g is transformed to obtain function h as shown.
(x)=4g(x+5)
A.
The graph of h is the graph of g vertically stretched by a factor of 4 and shifted 5 units to the left.
B.
The graph of h is the graph of g vertically shrunk by a factor of 4 and shifted 5 units to the right.
C.
The graph of h is the graph of g vertically stretched by a factor of 4 and shifted 5 units to the right.
D.
The graph of h is the graph of g vertically shrunk by a factor of 4 and shifted 5 units to the left.
Answer:
A
Step-by-step explanation:
The transformation is [tex]h(x)=4*g(x+5)[/tex].
4*g(x+5) means g(x) is vertically shifted by a factor if 4 by multiplying the entire function by 4. The values increase and are stretched (not shrunk to smaller).g(x+5) means the input x is increased by 5 each time. This results in a horizontal shift left on the graphThe answer is A. The graph of h is the graph of g vertically stretched by a factor of 4 and shifted 5 units to the left.

What is m∠C?
Enter your answer in the box.
Answer:
angle C is 60 degrees
Step-by-step explanation:
First you would solve for X
once you have that plug it in angle C
2(30)=60
Answer:
60°
Step-by-step explanation:
∠B is a right angle and all right angles are 90°, so if ∠B = 3*x then to find x you divid 3 by 90 to get x because 3*x = 90 once you do that you get 30 so x=30 then to find ∠C you just multiply 2 by 30 which gives you 60 which means the measure of ∠C = 60°

If the table is that of f(x), find a point that lies on the graph of f-^1(x).
Answer: D
Step-by-step explanation:
Inverse is when the x's and y's are swapped
x | y Inverse
-3 | 5 (5, -3)
-2 | -3 (-3, -2)
0 | 3 (3, 0)
1 | -5 (-5, 1) ← this matches choice D
2 | 6 (6, 2)
3 | 10 (10, 3)
So the correct answer Is A, but can you explain how you get that answer?
The first thing to notice is that the smaller triangle on the left is equilateral, because of the same single tickmarks on each of the three sides. For any equilateral triangle, each interior angle is 60 degrees as you have marked it on the drawing.
Once you determine that, you would solve for the 120 degree angle (60+120 = 180). Afterward, solve the equation 120+x+x = 180 to find that x = 30. The equation 120+x+x = 180 refers to adding up the three angles of the smaller triangle on the right side (with angles 120, x, x). The two missing angles are both x due to the fact that this triangle is isosceles.
Answer:
Step-by-step explanation:
Since ∆ABC is equilateral, all of its angles would be the same (60°). Since a line is 180°, the other part of ∠C is 120°. Since we also know that △BCD is isosceles, we know that angles ∠B and ∠D are equal. If a triangle is 180°, and we already know that ∠C is 120°, we can do 180-120, which is 60°. If angles ∠B and ∠D are equal, we can do 60/2=30. Therefore, ∠D is 30°.

Carol's age is three more than two times Lindsay's age. Carol is 39 years old. How old is Lindsay?
Let l = Lindsay's age in years.
3l + 2 = 39
2l–3=39
3l–2=39
2l + 3 = 39
Answer:
2l + 3 = 39
Step-by-step explanation:
the equation is 3 + 2L = C, where L is Lindsay's age and C is Carol's age
3 + 2L = 39
(4b) A rocking horse has a weight limit of 60 pounds. What percentage of the weight limit is 114 pounds? *
Answer:
190 percentage of the weight limit is 114 pounds.
Step-by-step explanation:
Given: A rocking horse has a weight limit of 60 pounds.
We have to find what percentage of the weight limit is 114 pounds.
x percentage of the weight limit is 114 pounds.
⇒ x% of 60 = 114
[tex]\frac{x}{100} \times 60 = 114[/tex]
Solve for x;
[tex]\frac{6x}{10} = 114[/tex]
Multiply both sides by 10 we get;
[tex]\frac{6x}{10} \times 10 = 114 \times 10[/tex]
[tex]6x = 1140[/tex]
Divide both sides by 6 we get;
[tex]x = \frac{1140}{6}[/tex]
Simplify:
x = 190%
Therefore, 190 percentage of the weight limit is 114 pounds.
To find the percentage, divide the given weight by the weight limit and multiply by 100. 114 pounds is 190% of the weight limit of 60 pounds.
To find the percentage of the weight limit, we need to divide the given weight (114 pounds) by the weight limit (60 pounds) and then multiply the result by 100. So, the calculation would be:
Percentage = (114 pounds / 60 pounds) * 100
Simplifying this equation, we get:
Percentage = 190%
Therefore, 114 pounds is 190% of the weight limit of 60 pounds.

Triangle STU is dilated to form new triangle VWX. If angle S is congruent to angle V, what other information will prove that the two triangles are similar? Side ST is congruent to side VW. Angle T is congruent to angle V. Side US is congruent to side XV. Angle U is congruent to angle X.
Answer:
(D)
Step-by-step explanation:
Two triangles are similar if it satisfies the following properties:
1) Corresponding angles are congruent.
2) Corresponding sides are all in same proportion.
Here, ΔSTU and ΔVWX are given, where ∠S is congruent to ∠V.
To prove these two triangles similar, we need one more corresponding angle to be congruent.
And from all the options, (d) Angle U is congruent to angle X. will help in proving ΔSTU and ΔVWX similar triangles.
Therefore, (d) is correct.
Answer:
d)Angle U is congruent to angle X.

Given the position function s(t)=(t^3/3)-(12t^2/2)+36t between t=0 and t=15, where s is given in feet and t is measured in seconds, find the interval in seconds where the particle is moving to the right.
Answer: [0, 6) ∪ (6, 15]
Step-by-step explanation:
The particle is moving to the right when the velocity is positive.
[tex]s(t)=\dfrac{t^3}{3} -\dfrac{12t^2}{2}+36t[/tex]
v(t) = s'(t)
= t² - 12t + 36
First, find the zeros of v(t): ⇒ v(t) = 0
0 = t² - 12t + 36
= (t - 6)²
0 = t - 6
6 = t
The zero occurs when t = 6
Next, find when v(t) > 0
Choose a test point between 0 and 6:
v(5) = (5 - 6)²
= (-²)
= (+)
Since velocity is positive between 0 and 6, the particle is moving to the right during that interval.
Choose a test point between 6 and 15:
v(7) = (7 - 6)²
= (+)²
= (+)
Since velocity is positive when t > 6, the particle is moving to the right.

−2
Answer:
2
Step-by-step explanation:
We can find the average rate of change by using the formula
rate of change = (y2-y1) /(x2-x1)
= (5-3)/(1-0)
= 2/1
=2
Answer:
A. 2
Step-by-step explanation:
average rate of change from x1 to x2 is
[f(x2) - f(x1)]/(x2 - x1)
Here we have x1 = -3; f(x1) = -3; x2 = 1; f(x2) = 5
average rate of change from x1 to x2 =
= [f(x2) - f(x1)]/(x2 - x1)
= [5 - (-3)]/(1 - (-3))
= 8/4
= 2

We have perpendicular bisector through a chord of the circle. We know the length, so either side of the chord is 11 due to the bisector cutting it directly in half. Since the radius is a fixed distance from the center to any point on the edge of the circle, we can draw the radius x from the circle to the end of the chord to form a right triangle.
We can use Pythagorean Theorem [tex]a^{2} +b^{2} =c^{2}[/tex] to find the missing side length x. a=6, b=11 and c=x.
[tex](6)^{2} +(11)^{2} =x^{2}[/tex]

Answer:
When f(x) is 0, then x is -1.8.
Step-by-step explanation:
To find this, you simply have to look for the place where the line crosses the x axis. This is where y (or f(x)) is equal to 0. Since this graph only crosses that axis at x = -1.8, that is the number we are looking for.
What is the length of cloth needed to make 18 shirts if each shirt is made from 0.8 yards of material?
