Answer:
4th choice: [tex]\frac{25x^2}{25y^2}[/tex]
Step-by-step explanation:
The ratio of areas is the square of the scale factor.
[tex]\left(\frac{2x}{5y}\right)^2=\frac{4x^2}{25y^2}[/tex]
The base of a triangle is 6 meters longer than the height of the triangle. If the area of the triangle is 56
square meters, what are the base and height of the triangle?
The height is
meters
The base is
meters
PLEASE HELP FOR EXAM
Answer:
Height = 8
Base = 14
Step-by-step explanation:
Base=x+6
Height=x
Area of a triangle is 1/2bh.
1/2·x·(x+6)=56
x²+6x=112
x²+6x-112=0
(x+14)(x-8)=0
x=-14 or x=8
Since x can’t equal a negative number, it must be 8.
Height=x = 8
Base=x+6 = 8+6 = 14

can someone please help me with this math question
Answer:
Step-by-step explanation:
A). From the table of relative frequencies,
Let the relative frequency of women who prefer mineral water = x
Total of relative frequencies of women preferring purified water and mineral water = 0.59
Since, Total of relative frequencies of women who prefer purified water and mineral water = Relative frequency of women preferring purified water + Relative frequency of women preferring mineral water
0.59 = 0.14 + x
x = 0.59 - 0.14
x = 0.45
B). Relative frequency of men who prefer mineral water = 0.13
Let the frequency of men who prefer mineral water = x
Since, relative frequency = [tex]\frac{\text{Frequency}}{\text{Total of frequencies}}[/tex]
0.13 = [tex]\frac{x}{200}[/tex]
x = 200 × 0.13
x = 26
Therefore, number of shoppers who are men and prefer mineral water = 26

A computer cost $800. It loses 1/4 of its value every year after it is purchased. complete the table to show the value of the computer at the listed times. Write an equation representing the values, v, of the computer, years after it is purchased. Used your equation to find v when t is 5. What does this value of v mean?
Answer:
The value after 0 years = $ 800
The value after 1 year = $600
The value after 2 years = $450
The value after 3 years = $337.5
The value after n years = computer cost at (n-1) year -
Step-by-step explanation:
he cost of computer = $ 800It losed 1/4th of value every year.The value of computer after 0 years = cost of computer = $ 800The value after 1 year = 800 - ( ) = $600The value after 2 years = 600 - ( ) = $450The value after 3 years = 450 - ( ) = $337.5The value after n years = computer cost at (n-1) year -We can conclude that -
the equation representing the value {v} of the computer, years after it is purchased as → v{x} = 800(1/4)ˣ.For {x} = 5, the value of {v} would be 0.39.What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that a computer cost $800. It loses 1/4 of its value every year after it is purchased.
We can write the equation representing the value {v} of the computer,
years after it is purchased as -
v{x} = 800(1/4)ˣ
For {x} = 5, we can write -
v{5} = 400(1/4)⁵
v{5} = 400 x 0.0009765625
v{5} = 0.39
Therefore, we can conclude that -
the equation representing the value {v} of the computer, years after it is purchased as → v{x} = 800(1/4)ˣ.For {x} = 5, the value of {v} would be 0.39.To solve more questions on functions, visit the link below-

A.
F(x) = –x2 – 3
B.
F(x) = x2 – 3
C.
F(x) = –(x + 3)2
D.
F(x) = –(x – 3)2
Answer:
the answer is A
Step-by-step explanation:
The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has been changed somewhat. Which of the following could be the equation of F(x)?
The function that represents the situation is F(x) = -x² - 3.
The correct option is A.
What is transformation on the graphs?Let the functions f(x) and g(x) be two real functions.
And g (x) = f (x) + k, where k is real numbers.
The function can be sketched by shifting f (x), k units vertically.
The value of k can find the direction of shift:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
Given that the parent function is g(x) = x².
To find the transformed function F(x):
The function's diagram is in the opposite direction.
That means the function is -x².
And the function is shifted 3 units down vertically.
From the definition the required function is,
F(x) = -x² - 3.
Therefore, F(x) = -x² - 3.

Given:
The line passes through the two points (–4, –3) and (12, 1).
The point-slope form of the equation of the line is:
[tex]y-1=\dfrac{1}{4}(x-12)[/tex]
To find:
The standard form of the equation for this line.
Solution:
The standard form of a line:
[tex]Ax+By=C[/tex]
The given point-slope form of the equation of the line is:
[tex]y-1=\dfrac{1}{4}(x-12)[/tex]
Multiply both sides by 4.
[tex]4(y-1)=(x-12)[/tex]
[tex]4y-4=x-12[/tex]
[tex]-4+12=x-4y[/tex]
[tex]8=x-4y[/tex]
Interchanging the sides, we get
[tex]x-4y=8[/tex]
Therefore, the standard form of the equation for this line is [tex]x-4y=8[/tex].
