What is the function of this graph?
Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right.
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right.
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong.

A tree planter can plant 40 trees in 8 hours.
How many trees can a tree planter plant in 2
hours?
Answer:
He can plant 10 trees in 2 hours.
Step-by-step explanation:
First you need to find the number of trees he can plant in an hour.
For this purpose, we will divide 40 by 8 to get an idea about how many he can plant in an hour.
Trees planted in an hour = 40/8 = 5
Now for 2 hours = 5*2 = 10 trees.
Consider the diagram below of an equilatera triangle.
Answer:
4 = n.
13 ft.
Step-by-step explanation:
An equilateral triangle means that all of the sides are equal.
This means: 2n + 5 = 3n + 1 = 5n -7
You can pick two of those sides to set up an equation to solve for n.
For example, 2n + 5 = 3n + 1.
Then you will need to isolate the variable.
Subtract 1 from each side to get 2n + 4 = 3n.
Subtract 2n from each side to get 4 = n.
Substitue 4 for n into one of the equations.
2n + 5
2(4) + 5
8 + 5 = 13
Each side is 13 ft.
Richard Brian puts $30 worth of gas in his truck. The price per gallon was $2.50. Which equation can be solved to find the number of gallons Richard Brian's purchased?
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Richard Brian puts $30 worth of gas in his truck and the price per gallon was $2.50.
The equation that can be solved to find the number of gallons Richard Brian's purchased will be the worth of gas in the truck divided by the price per gallon. This will be:
x = 30 / 2.50
where x = number of gallon.
= 12 gallons

Please answer them all I will award brainliest answer <3
Answer:
Step-by-step explanation:
4(y+3)+2(y+7) = 2(3y`=13)
6(2w+5)+9(w+2) = 3(7w+16)
3(y-2)+4(2y+5) = 11y+4
7(2g+3)-5(g+2)= 9g+11
6(x-2)-4(x-8) = 2(x+10)
2(3y-8)-5(2y-1) = -4y-11
8(5+2m) +3(5-3m) = 55+7m
4(w+7)-2(2w+1) = 26

Answer:
1.) y=4.3
2.) w=2.2

Colin was thinking of a number. Colin halves it and gets an answer of 5.2. What was the original number?
Answer: 10.4
Step-by-step explanation:
Let the number that Colin is thinking of be represented as x.
We are informed that Colin halves the number and gets an answer of 5.2. This can be written as:
x ÷ 1/2 = 5.2
0.5x = 5.2
Divide through by 0.5
0.5x/0.5 = 5.2/0.5
x = 10.4
The number is 10.4
The shelf life of a battery produced by a major company is known to be normally distributed, with a mean life of 4 years and a standard deviation of 0.75 years. What is the upper quartile of the battery shelf life? What range of years contains the middle 68% of all battery shelf lives?
Answer:
4.5 years ; (3.25, 4.75)
Step-by-step explanation:
Given that :
Mean , m = 4
Standard deviation, s = 0.75
The upper quartile, which is the 3rd quartile of a standard normal distribution is 0.67
Therefore, the upper quartile Q3:
Q3 = mean + 0.67 * standard deviation
Q3 = 4 + 0.67(0.75)
Q3 = 4 + 0.5025
Q3 = 4.5025
Q3 = 4.5 years
Range of values that contain the middle 68%
According to the empirical rule;
68% is within 1 standard deviation of the mean
Therefore ;
Interval will be ;
Mean ± 1 standard deviation
(4 - 0.75) ; (4 + 0.75)
(3.25, 4.75)
For two days, your boss decides to double the amount you make if on day 1, you make $70 dollars and on day 2, you make$80 dollars, write an expression for the total commission you earn?
Answer:
300
Step-by-step explanation:
Day 1: $70
Day 2: $80
Total commission = day 1 × 2 + day 2 × 2
= 70 × 2 + 80×2
= 140 + 160
= 300
Or
Total commission = 2(day 1 + days 2)
= 2(70 + 80)
= 2(150)
x = 300

Answer:
x = 30°
Step-by-step explanation:
Since 2 of the sides are congruent then the triangle is isosceles and the 2 base angles are congruent, both 75°
The sum of the 3 angles in a triangle = 180°, then
x = 180° - (75 + 75)° = 180° - 150° = 30°
The perimeter of square is 24 meters. What is the length of one side of the square. Show your work
