62.4% of what number is 17.16?
What percent of 51 is 127.5?
(Those are two questions but like on the same thing )
Answer:
first: 27.5
second: 250%
Step-by-step explanation:
first: 17.16 ÷ 62.4% = 0.275, 27.5
second: 51 ÷ 127.5 = 0.4, 40%,
100% ÷ 40%, = 2.5, 250%

Fungsi kuadratik f(x) = x2 - 6x + c melalui titik B(-2,4). Apakah nilai bagi c?
The quadratic function f(x) = x2 - 6x + c passes through point B(-2,4). What is the
value of c?
A -12
B -6
C 6
D 12
Given:
Quadratic function is
[tex]f(x)=x^2-6x+c[/tex]
It passes through B(-2,4).
To find:
The value of c.
Solution:
The quadratic function passes through B(-2,4), it means the equation of quadratic equation must be true for the point B(-2,4).
We have,
[tex]f(x)=x^2-6x+c[/tex]
Putting x=-2 and f(x)=4, we get
[tex]4=(-2)^2-6(-2)+c[/tex]
[tex]4=4+12+c[/tex]
[tex]4=16+c[/tex]
Subtract both sides by -16.
[tex]4-16=c[/tex]
[tex]-12=c[/tex]
The value of c is -12.
Therefore, the correct option is A.

a sequence has a first number of 3 and a half common difference of 4 what is the recursive rule of nth term
Answer:
[tex]f(n) = f(n-1) + 8[/tex] for [tex]n > 1[/tex]
Step-by-step explanation:
Given
[tex]f(1) = 3[/tex] -- First Term
[tex]\frac{1}{2}d = 4[/tex] --- half common difference
Required
Find the recursive rule
First, we calculate the common difference
[tex]\frac{1}{2}d = 4[/tex]
Multiply through by 2
[tex]2 * \frac{1}{2}d = 2 * 4[/tex]
[tex]d = 8[/tex]
The second term of the sequence is:
[tex]f(2) = 3 + 8 = 11[/tex]
The third term is:
[tex]f(3) = 11 + 8 = 20[/tex]
So, we have:
[tex]f(1) = 3[/tex]
[tex]f(2) = 3 + 8[/tex]
Substitute f(1) for 3
[tex]f(2) = f(1) + 8[/tex]
Express 1 as 2 - 1
[tex]f(2) = f(2-1) + 8[/tex]
Substitute n for 2
[tex]f(n) = f(n-1) + 8[/tex]
Similarly:
[tex]f(3) = 11 + 8[/tex]
Substitute f(2) for 11
[tex]f(3) = f(2) + 8[/tex]
Express 2 as 3 - 1
[tex]f(3) = f(3-1) + 8[/tex]
Substitute n for 3
[tex]f(n) = f(n-1) + 8[/tex]
Hence, the recursive is:
[tex]f(n) = f(n-1) + 8[/tex] for [tex]n > 1[/tex]

Gerald is conducting an experiment with 3 possible outcomes. Kasey is conducting an experiment with 20 possible outcomes. Which statement best relates the possible outcomes to the number of trials needed to produce results similar to their predicted outcomes?
Answer:
Following are the solution to this question:
Step-by-step explanation:
The experiment of three possible results has been performed through Gerald. This statement better applies to the data point to obtain results comparable to the findings expected.
The amount of potential scenarios predicted from the above claim is three (smaller than) twenty potential scenarios, as indicated in the 2nd statement. Throughout the case with good predictive claims, the 1st claim sounds very good.
B, Gerald will need to conduct fewer trials than Kasey because there are fewer possible outcomes in his experiment.

Answer:
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is [tex]\frac{3}{4}[/tex] ⇒ B
Step-by-step explanation:
In similar rectangles, their corresponding dimensions are proportional, which means [tex]\frac{L_{1} }{L_{2}}[/tex] = [tex]\frac{W_{1} }{W_{2}}[/tex] , where L is the length and W is the width
∵ Rectangle ABCD is similar to rectangle MNOP
∴ Their dimensions are proportional
∵ The dimensions of rectangle ABCD are 6 m, 14 m
∴ L[tex]_{1}[/tex] = 14 and W[tex]_{1}[/tex] = 6
∵ The dimensions of rectangle MNOP are 4.5 m, 10.5 m
∴ L[tex]_{2}[/tex] = 10.5 and W[tex]_{2}[/tex] = 4.5
∵ The rectangle MNOP is the image of rectangle ABCD after dilation
→ To find the scale factor of dilation find the ratio between the
corresponding dimensions in the two rectangles (image/pre-image)
∵ [tex]\frac{L_{2} }{L_{1}}[/tex] = [tex]\frac{10.5}{14}[/tex] = [tex]\frac{3}{4}[/tex]
∵ [tex]\frac{W_{2} }{W_{1}}[/tex] = [tex]\frac{4.5}{6}[/tex] = [tex]\frac{3}{4}[/tex]
∴ The scale factor for the dilation is [tex]\frac{3}{4}[/tex]
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is [tex]\frac{3}{4}[/tex]

The first two terms in an arithmetic progression are -2 and 5. The last term in the progression is the only number in the progression that is greater than 200. Find the sum of all the terms in the progression.
Given:
The first two terms in an arithmetic progression are -2 and 5.
The last term in the progression is the only number in the progression that is greater than 200.
To find:
The sum of all the terms in the progression.
Solution:
We have,
First term : [tex]a=-2[/tex]
Common difference : [tex]d = 5 - (-2)[/tex]
[tex]= 5 + 2[/tex]
[tex]= 7[/tex]
nth term of an A.P. is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
[tex]a_n=-2+(n-1)(7)[/tex]
According to the equation, [tex]a_n>200[/tex].
[tex]-2+(n-1)(7)>200[/tex]
[tex](n-1)(7)>200+2[/tex]
[tex](n-1)(7)>202[/tex]
Divide both sides by 7.
[tex](n-1)>28.857[/tex]
Add 1 on both sides.
[tex]n>29.857[/tex]
So, least possible integer value is 30. It means, A.P. has 30 term.
Sum of n terms of an A.P. is
[tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
Substituting n=30, a=-2 and d=7, we get
[tex]S_{30}=\dfrac{30}{2}[2(-2)+(30-1)7][/tex]
[tex]S_{30}=15[-4+(29)7][/tex]
[tex]S_{30}=15[-4+203][/tex]
[tex]S_{30}=15(199)[/tex]
[tex]S_{30}=2985[/tex]
Therefore, the sum of all the terms in the progression is 2985.
the depth of water at the end of a boat dock can be modeled by a senusoidal function Y=Asin [B(r+C) ]+D where y represents the depth in feet of the water, hours after midnight on a certain day, the depth is 10 feet at low tide at 6 am and 18 feet at high tide at noon find the amplitude and midline for the general sine function that can be used to model the water's depth.
Answer:
A=4 ft
Midline: y=14
Step-by-step explanation:
When talking about sinusoidal waves, we know the amplitude will be the distance between the midline and the highest or lowest point of the graph. This can be found by first, finding the distance between the lowest point and the highest point:
d= 18ft - 10ft = 8ft
and divide this distance into 2:
[tex]A=\frac{8}{2}[/tex]
A= 4 ft
in order to find the midline, we need to figure the midpoint between the highest and lowest value. We can do so by using the following formula:
[tex]Midpoint=\frac{high+low}{2}[/tex]
so:
[tex]Midpoint=\frac{18+10}{2}[/tex]
Midpoint = 14
so the midline is located at the line:

Find F^-1(x), the inverse of F(x).
f(x)-9x^3-4
Show your work please because I don’t understand.
Hi there!
[tex]\large\boxed{f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} } }[/tex]
[tex]f(x) = 9x^{3} - 4[/tex]
Find the inverse by replacing f(x) with y and swapping the x and y variables:
[tex]x = 9y^{3} - 4[/tex]
Isolate y by adding 4 to both sides:
[tex]x + 4 = 9y^{3}[/tex]
Divide both sides by 9:
[tex]\frac{x+4}{9}= y^{3}[/tex]
Take the cube root of both sides:
[tex]y = \sqrt[3]{\frac{x+4}{9} }\\\\f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} }[/tex]

The coordinate of A' is (-5, 3)
Option b is true.
Given that;
The coordinate of A is (3, 5)
And, To rotate ABCD 90° counterclockwise about the origin.
We have to find the coordinate of A'.
What is Rule of 90° counterclockwise rotation about the origin?
If we rotate 90° counterclockwise about the origin then the coordinate A (x, y) become A' (-y, x).
The coordinate of A is (3, 5).
By the rule of 90° counterclockwise rotation about the origin;
We get, After rotation 90° counterclockwise rotation about the origin the coordinate A (3, 5) become A' (-5, 3)
Hence, The coordinate of A' is (-5, 3)
Option b is true.
