Which of the following is the graph of y=sqrt x+1?
Answer:
B
Step-by-step explanation:
The graph for y= √x+1 is shown below.
What is the square root function?The square root function f(x)=√x has domain [0,∞) with range [0,∞).
Similarly the given function is y=f(x)= √x+1
From the graph, it is clear that the function is valid for x≥0 because x<0 √x will be imaginary.
So the domain of the function f(x)= √x+1 will be [0,∞).
As we know,
√x ≥0
⇒ √x+1≥0+1
⇒√x+1 ≥ 1
⇒f(x) ≥ 1
the function f(x) has range [1,∞).
f(x)=√x+1 ha y intercept at x=0
f(0)= √0+1=1
f(x) has y intercept at (0,1).
Function F(x) will increase from point (0,1).
Therefore The graph for y= √x+1 is shown below.

wrongStep-by-step explanation:
Segment bisector is the line in half
The segment bisector of MN is JK and the measure of MN is 52.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The only bisector of MN is JK and it is at the midpoint of the line segment MN so it will be a bisector.
Now,
Since JK is the bisector of MN
M(JK) = (JK)N
26 = (JK)N
So,
MN = 2(26) = 52
Hence "The segment bisector of MN is JK and the measure of MN is 52".

Log2 x + log2 (6-x)=3 solve for x algebraically
Answer:
The solution is x = 2 and x = 4
Step-by-step explanation:
Let us revise some rules in logarithmic function:
[tex]log_{a}(x)+log_{a}(y)=log_{a}(xy)[/tex]The logarithmic function is the inverse of the exponential function [tex]log_{b}(c)=a[/tex] is the inverse of [tex]b^{a}=c[/tex]Let us solve the question
∵ [tex]log_{2}(x)+log_{2}(6-x)=3[/tex]
→ By using the first rule above
∴ [tex]log_{2}(x)(6-x)=3[/tex]
→ Multiply x by (6 - x)
∵ x(6 - x) = x(6) - x(x) = 6x - x²
∴ [tex]log_{2}(6x-x^{2})=3[/tex]
→ Change the logarithmic function to exponential function using
the second rule above
∴ [tex]2^{3}=(6x-x^{2})[/tex]
∵ 2³ = 8
∴ 8 = 6x - x²
→ Add x² to both sides
∴ x² + 8 = 6x
→ Subtract 6x from both sides
∴ x² - 6x + 8 = 0
→ Factorize it into 2 brackets
∴ (x - 2)(x - 4) = 0
→ Equate each factor by 0 to find the values of x
∵ x - 2 = 0
→ Add 2 to both sides
∴ x = 2
∵ x - 4 = 0
→ Add 4 to both sides
∴ x = 4
∴ The values of x are 2 and 4
∴ The solution of the equation is x = 2 and x = 4

A stadium has 55,000 seats. Seats sell for $42 in Section A, $24 in Section B, and $18 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,738,800 from each sold-out event. How many seats does each section hold?
Answer:
Section A = 27,500 seats
Section B = 14,800 seats
Section C = 12,700 seats
Step-by-step explanation:
Section A = $42
Section B = $24
Section C = $18
Revenue = $1,738,800
Total number of seats = 55,000
The number of seats in Section A equals the total number of seats in Sections B and C
A = B + C
A + B + C = 55,000
42A + 24B + 18C = $1,738,800
Substitute A = B + C into the equations
B + C + B + C = 55,000
42(B + C) + 24B + 18C = $1,738,800
2B + 2C = 55,000
42B + 42C + 24B + 18C = 1,738,800
2B + 2C = 55,000
66B + 60C = 1,738,800
Multiply (1) by 30
60B + 60C = 1,650,000. (1)
66B + 60C = 1,738,800. (2)
Subtract (1) from (2)
66B - 60B = 1,738,800 - 1,650,000
6B = 88,800
B = 88,800/6
= 14,800
B = 14,800
Substitute the value of B into
2B + 2C = 55,000
2(14,800) + 2C = 55,000
29,600 + 2C = 55,000
2C = 55,000 - 29,600
2C = 25,400
C = 25,400/2
= 12,700
C = 12,700
Substitute the values of B and 6 into
A + B + C = 55,000
A + 14,800 + 12,700 = 55,000
A + 27,500 = 55,000
A = 55,000 - 27,500
= 27,500
A = 27,500
Section A = 27,500 seats
Section B = 14,800 seats
Section C = 12,700 seats
Answer:
Section A has 27,500 seats
Section B has 14,800 seats
Section C has 12,700 seats
Step-by-step explanation:
To solve this, we will have equations:
let x = seats at section A
y= seats at section B
Z = seats at section C
we will get the following equation:
So from the question, x = y + z ..........(1)
x + y + z = 55,000 .........(2)
42x + 24y + 18z = 1,738,800 .... (3)
input equation (1) into (2)
y + z + y + z = 55,000
2y + 2z = 55,000...... (4)
so for exuation (3), input equation (1) into (3):
42x + 24y + 18z = 1,738,800
42(y + z) + 24y + 18z = 1,738,800
42y + 42z + 24y + 18z = 1,738,800
collect like terms:
66y + 60z = 1,738,800 ..... (5)
multiply equation (4) by -30. -30 is chosen to remove z from the equation so we could get what y is
-60y - 60z = - 1,650,000 ...... (6)
add equation (5) and (6)
6y + 0 = 88,800
y = 14,800 seats
Input the value of y into equation (4) to find z
2y + 2z = 55,000
2(14,800) + 2z = 55,000
29,600 + 2z = 55,000
2z = 25,400
z = 12,700 seats
To find the number of seats in section A we use equation (2)
x + y + z = 55,000
x +14,800 + 12,700 = 55,000
x + 27,500 = 55,000
x = 27,500 seats
To verify our answer to see if the number of seats in Section A equals the total number of seats in Sections B and C.
total number of seats in Sections B and C = 14,800 + 12,700 = 27,500
so number of seats in section A = B + C

You need two bottles of fertilizer to treat the flower garden shown. How many bottles do you need to treat a similar garden with a perimeter of 105 feet? A flower garden in the form of trapezoid is shown. The length of longer base is labeled 18 feet, shorter base is 15 feet, height is 4 feet, and one leg is 5 feet.
Answer:
26.25 bottles
Step-by-step explanation:
A flower garden in the form of trapezoid is shown. The length of longer base is labeled 18 feet, shorter base is 15 feet, height is 4 feet, and one leg is 5 feet.
Formula for perimeter of a trapezoid = Side a + side b + length a + length b
For the trapezium shown, its perimeter step 1,
we have to find the missing length
Length a
We are given height = 4 feet
Length of the longer base = 18 feet
Length of the shorter base = 15 feet
Different would give us the base of the right angle triangle
= 18 - 15 = 3 feet
Using Pythagoras Theorem we can find the side a = c
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
c = √25
c = 5 feet
Hence side a = 5 feet
Perimeter of the Trapezoid shown =
18 feet + 15 feet + 5 feet + 5 feet
= 38 feet.
From the question,
You need two bottles of fertilizer to treat the flower garden shown. How many bottles do you need to treat a similar garden with a perimeter of 105 feet
Hence:
38 feet = 2 bottles
105 feet = x bottles
Cross y
= 38 × x = 105 × 2
= 38x = 105 × 2
x = 105 × 2/38
x = 26.25 bottles
26.25 bottles of fertilizer is needed to treat the garden with a perimeter of 105

Step-by-step explanation:
You are expected to compare each line to the previous line and identify the changes. Apart from combining like terms (collecting terms), there are generally only three properties of interest: distributive property, addition property, multiplication property. Of course, subtraction and division are just addition and multiplication using the appropriate (additive, multiplicative) inverse.
The distributive property involves adding or deleting parentheses, so it is easy to identify.
If terms disappear, it can be due to terms being combined, or due to addition/subtraction. If coefficients disappear, it will generally be due to multiplication/division.

Bijou Museum sells 75% of its tickets for the regular price of $14. The remaining discount tickets are sold for the price of $10. Variable cost per guest is $2 for both groups, and fixed costs total $66,000 per month. What are the number of regular-price guests and discount guests at the breakeven point?
Answer:
Regular price guests = 3300
Discount price guests = 1100
Step-by-step explanation:
Breakeven point is the point where total revenue and total cost are equal.
Now, we know total cost is $66,000 per month.
Now, we are told that the museum sells 75% of its tickets for the regular price of $14.
If the total number of tickets is x. It means the number of regular tickets guests is 75%x = 0.75x
We are told that variable cost per guest in each group is $2. This means that total revenue from regular tickets guest is;
14(0.75x) + 2(0.75x) = 12x
Now, the remaining tickets are discount tickets sold for $10.
It means number of discount tickets guests = 0.25x
Total revenue from discount tickets =
10(0.25x) + 2(0.25x) = 3x
Thus, at break even point, we have;
12x + 3x = 66000
15x = 66000
x = 66000/15
x = 4400
Thus;
Regular price guests = 0.75 × 4400 = 3300
Discount price guests = 0.25 × 4400 = 1100

Determine whether the statements are True or False. Justify your answer with an explanation.
If f(x) = x + 1 and g(x) = 6x, then (f ○ g)(x) = (g ○ f)(x).
If you are given two functions f(x) and g(x), you can calculate (f ○ g)(x) if and only if the range of g is a subset of the domain of f.
Problem 1
Answer: False---------------------------------
Explanation:
The notation (f o g)(x) means f( g(x) ). Here g(x) is the inner function.
So,
f(x) = x+1
f( g(x) ) = g(x) + 1 .... replace every x with g(x)
f( g(x) ) = 6x+1 ... plug in g(x) = 6x
(f o g)(x) = 6x+1
Now let's flip things around
g(x) = 6x
g( f(x) ) = 6*( f(x) ) .... replace every x with f(x)
g( f(x) ) = 6(x+1) .... plug in f(x) = x+1
g( f(x) ) = 6x+6
(g o f)(x) = 6x+6
This shows that (f o g)(x) = (g o f)(x) is a false equation for the given f(x) and g(x) functions.
===============================================
Problem 2
Answer: True---------------------------------
Explanation:
Let's say that g(x) produced a number that wasn't in the domain of f(x). This would mean that f( g(x) ) would be undefined.
For example, let
f(x) = 1/(x+2)
g(x) = -2
The g(x) function will always produce the output -2 regardless of what the input x is. Feeding that -2 output into f(x) leads to 1/(x+2) = 1/(-2+2) = 1/0 which is undefined.
So it's important that the outputs of g(x) line up with the domain of f(x). Outputs of g(x) must be valid inputs of f(x).
The given statement is false.
What is composite function ?Composite function is a combination of two or more than two functions combined by mathematical operation of addition,subtraction,multiplication and division.Where output of one function is input to the other function.
According to the given question two functions are given f(x) and g(x) and and we have to compose in different order and see if they are same or not.
Given, f(x) = x + 1 and g(x) = 6x
So, (fog)(x) is, output of g(x) is the input of f(x) which is
f(6x) = (6x) + 1
f(6x) = 6x + 1.
Now, (gof)(x) is, output of f(x) is now input of g(x) which is
g(x+1) = 6(x+1)
g(x+1) = 6x + 6.
Thus we can see fog(x) ≠ gof(x).
