Which function defines (g•f)?
f(x)= log(5x)
g(x) = 5x + 4
A. (g•f)(x)= 5x log(5x) + 4log(5x)
B. (g•f)(x) = 5x + 4 + log(5x)
C. (g•f)(x) = 5x – 4 – log(5x)
D. (g•f)(x) = 5x log(5x) + 4
Answers
Answer:
A
Step-by-step explanation:
A. (g•f)(x)= log(5x) ( 5x + 4)=5x log(5x) + 4log(5x)
The function 5x log(5x) + 4log(5x) defines (g•f)
We have given that,
A. (g•f)(x)= 5x log(5x) + 4log(5x)
B. (g•f)(x) = 5x + 4 + log(5x)
C. (g•f)(x) = 5x – 4 – log(5x)
D. (g•f)(x) = 5x log(5x) + 4
We have to determine which function defines (g•f)
Where f(x)=log(5x) and g(x)=5x+5
What is the multiplication function?
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
A. (g•f)(x)= log(5x) ( 5x + 4)=5x log(5x) + 4log(5x)
(5x+4)(log(5x))=5x(log(5x))+4(log(5x))
Therefore the option A is correct.

A swimming pool in the shape of a cylinder with a diameter of 10 m and a depth of 3 m is being filled with water. 27,535 L have been added so far. 1 m3 is equal to 1000 L. To the nearest liter, how much more water can the pool hold?
A. 236,000 L
B. 208,084 L
C. 236,616 L
D. 207,314 L
No dam links
Answers
Answer:
207,314
Step-by-step explanation:
V = πr2h =π · 52·3 ≈ 235.61945 m^3
because 1m^3 = 1000 L, (27,535 / 1000) = the amount of added water in m^3. As this is equal to 27.535, we can substract this from 235.62.
235.62 - 27.535 is about 208.085, or 207.314 because of rounding. As this is in m^3, we multiply by liters to arrive at the answer of 207,314, or option D.
An insect population triples every 4 months. If the population started out with 24 insects, how many
insects would there be in 16 months?
Answers
Answer:
After 16 months there will be a population of 1,944 insects.
Step-by-step explanation:
Since an insect population triples every 4 months, if the population started out with 24 insects, to determine how many insects would there be in 16 months, the following calculation must be performed:
X = 24 x 3 ^ (16/4)
X = 24 x 3 ^ 4
X = 1,944
Thus, after 16 months there will be a population of 1,944 insects.

Answers
Answer:
Last one. Combine like terms onto side of the equation.
Step-by-step explanation:
The first step in determining the solution to the system of equations, [tex]y = -x^2 - 4x - 3[/tex] and [tex]y = 2x + 5[/tex] , algebraically is to set the two equations equal as [tex](-x^2 - 4x - 3) = 2x + 5[/tex], will be to set the equations equal to each other.
What is system of equations ?System of equations comprises of two or more equations of two or more variables and seeks common solutions to the equations.
We have,
[tex]y = -x^2 - 4x - 3[/tex]
[tex]y = 2x + 5[/tex]
So, to determine solution to these System of equations,
We have to
Set the equations equal to each other and solve for the value of [tex]x[/tex],
i.e.
[tex]-x^2 - 4x - 3=2x+5[/tex]
[tex]-x^2-6x-8=0[/tex]
[tex]x^2+6x+8=0[/tex]
[tex]x^2+4x+2x+8=0[/tex]
[tex]x(x+4)+2(x+4)=0[/tex]
[tex](x+2)(x+4)=0[/tex]
⇒ [tex]x+2=0[/tex]
[tex]x=-2[/tex]
[tex]x+4=0[/tex]
[tex]x=-4[/tex]
So, from the above solution we came to know that the first step in determining the solution to the given System of equations is to set the equations equal to each other.

A rectangle has a perimeter of 42 ft its length, L, is 3 feet more than twice its width, W.
(c) Solve the system of equations that you just created by substitution to find the values of the length and width.
Answers
Answer:
Length of rectangle = 15 feet
Width of rectangle = 6 feet
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 ft
Length of rectangle = 2[Width of rectangle] + 3
Find:
Value of length and width
Assume:
Width of rectangle = w
SO,
Length of rectangle = 2[w] + 3
Perimeter of rectangle = 2[l + b]
42 = 2[2w + 3 + w]
2[3w + 3] = 42
6w + 6 = 42
6w = 42 - 6
6w = 36
w = 36 / 6
w = 6
So,
Width of rectangle = 6 feet
Length of rectangle = 2[w] + 3
Length of rectangle = 2[6] + 3
Length of rectangle = 12 + 3
Length of rectangle = 15 feet
