Answer:
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Step-by-step explanation:
So first let's write a graph in vertex form with a vertex of (-5, -1)
We get
a(x+5)²-1
We now need to determine a
we know that when x= -2 y=2 which means we have
a(-2+5)²-1=2
Solve for a
a(3)²=3
9a=3
a=3/9
a=1/3
Now that we know what a is equal to we can write our equation
[tex](\frac{1}{3})(x+5)^2-1[/tex]

Tom has three times as many action figures as Jerry. If Tom has 27 action figures, how many does Jerry have? Write an equation that represents the scenario. Then solve.
Answer:
Jerry has 9 action figures.
Step-by-step explanation:
Since Tom has three times as many action figures as Jerry, Tom has 3x action figures, where x is the number of action figures that Jerry has.
Since Tom has 27 action figures, we can say that 3x=27.
3x=27
x=9

suppose potatoes cost $0.99 per pound. complete the function rule c=? to describe the relationships between the total cost c and the number of pounds of potatoes p you buy.
Answer:
c=p*0.99
you gonna multiply the amt of patatoes by the cost of one to get the total like if you were buying 5 you would multiply 5 by 99 to get the total
P = $0.99
C = [tex]P * x[/tex]
[Note: x is how many pounds of potatoes you buy.]

what is the smallest integer greater than the square root of 85?
Answer:
the answer is 9.2
Step-by-step explanation:
The radical value √(85) lies between 81 and 100. So, the smallest integer greater than the square root of 85 is 10.
Radical:Important information:
The given radical value is [tex]\sqrt{85}[/tex].The perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
It is clear that,[tex]81<85<100[/tex]
Taking square root on each side, we get
[tex]\sqrt{81}<\sqrt{85}<\sqrt{100}[/tex]
[tex]9<\sqrt{85}<10[/tex]
The value [tex]\sqrt{85}[/tex] lies between 9 and 10.
Therefore, the smallest integer greater than the radical value square root of 85 is 10.

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating
Answer:
Option D
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:
c² = a² + b²
From the options, option d is the correct option.
For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:
c² = a² + x²
x² = c² - a²
x = √(c² - a²)
Therefore the other leg would be √(c² - a²)

There are 14 girls and 12 boys in a class. What is the ratio of girls to students?
Answer:
7:13
Step-by-step explanation:
There are 14 girls and 12 boys, so there are 26 students in total. Since we are looking for the ratio of girls to students, the ratio will be 14:26. To simplify it, we will divide 14 and 26 by their greatest common factor: 2. We will get the ratio of 7:13.

Machine A and machine B both make car parts.
Machine A makes 7 parts every 10 minutes.
Machine B makes 16 parts every 15 minutes.
On Monday
machine A makes parts for 12 hours
machine B makes parts for 10 hours
Work out the total number of parts made by the two machines on Monday.
Answer: 1144
Step-by-step explanation:
Given: Machine A makes 7 parts every 10 minutes.
i.e. it makes [tex]\dfrac{7}{10}[/tex] parts in 1 minute.
Machine B makes 16 parts every 15 minutes.
i.e. it makes [tex]\dfrac{16}{15}[/tex] parts in 1 minute.
On Monday,
machine A makes parts for 12 hours(720 minutes). [1 hour = 60 minutes, 12 hours = 12 x 6 = 720 minutes]
i.e. Total parts made = [tex]\dfrac{7}{10}\times720[/tex]
i.e. Total parts made = 504
machine B makes parts for 10 hours(=60x 10=600 minutes)
i.e. Total parts made = [tex]\dfrac{16}{15}\times600[/tex]
i.e. Total parts made = 640
Total parts made by both machines = 504+640 =1144
Hence, the total number of parts made by the two machines on Monday=1144.

A. the year growth rate of the population is 0.06%
B. the yearly growth rate of the population is 0.6%
C. the yearly growth rate of the population is 1.06%
D. the yearly growth rate of the population is 6%
please respond if you actually know the answer :)
Answer:
D
Step-by-step explanation:
.06 =6%
The expression p(1.06)^t represents D. the yearly growth rate of the population is 6%
What is the population growth rate?The country's yearly average rate of change in population size over a certain time period. It expresses the proportion, growth in population size, and the total population for that year.
Given, The population of a city can be modeled by the expression
[tex]p(1.06)^t[/tex] where t represents the number of years.
This describes the yearly growth rate of the population is 6%.
If in the previous year the population was 100 this year it'll be 106 and next year it'll be 106% of 106 which is 112.36.

The average value of a function f on [a, b]
always lies between f(a) and f(b). Justify your answer.
Answer:
False
Step-by-step explanation:
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi]. sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
The average value of a function f on [a, b] always lies between f(a) and f(b) is false.
What is a function?A relation is a function if it has only One y-value for each x-value.
The average value of a function over an interval [a,b] is the total area over the length of the interval
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi].
sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
So the average value of a function f on [a, b] always lies between f(a) and f(b) is false.
Hence, the average value of a function f on [a, b] always lies between f(a) and f(b) is false.
