Answer:
The equation is y = x(x-12)
Vertex form
is y = a(x-6)^2 + 4
where a is -1/9
Step-by-step explanation:
For the general equation, we have the roots at x = 0 or x = 12
so we have x and x -12
So we have the equation as;
y = (x-0)(x-12)
y = x(x-12)
y = x^2 - 12x
The vertex form equation of a quadratic equation is;
y = a(x-h)^2 + k
where (h,k) represents the vertex which we have above as (6,4)
So while substituting 6 for h, we have 4 for k
So we have it that;
y = a(x-6)^2 + 4
Substituting 0 for x and 0 for y, we have it that;
0= a(0-6)^2 + 4
0 = 36a + 4
-4 = 36a
a = -4/36
a = -1/9

Answers
Step-by-step explanation:
mass of earth=5.976×10^24 and
mass of Uranus =8.68×10^25
the mass of
Uranus is greater than that of the Earth by comparing its power 10
The mass of Uranus is greater than that of the Earth by comparing its power 10
What is an exponential form of 10?It is a shortcut way of writing repeated multiplication involving base and exponents. For example the 3 in [tex]10^{3}[/tex] is called the exponent. The expression [tex]10^{3}[/tex] is called exponential expression.
Given
Mass of the earth = 5976000000000000000000000 kg
Rewrite in exponential form
Mass of the earth = 5.976×10^24
Mass of Uranus = 86800000000000000000000000 kg
Rewrite in exponential form
Mass of the Uranus = 8.68×10^25
∴ 8.68 × [tex]10^{25}[/tex] > 5.976 × [tex]10^{24}[/tex]
We can clearly say that by seeing the exponential form of masses of earth and Uranus i.e.,
The mass of Uranus is greater than that of the Earth by comparing its power 10.

Write the slope intercept form of the equation for a line passing through (-3,-1) and
(0,4)
Answers
Answer:
y = 5/3x + 4
Step-by-step explanation:
First, you need to find the slope. Use the slope formula of (y^2-y^1) / (x^2 - x^1).
Plug the numbers in.
(4 - (-1)) / (0 - (-3))
5 / 3
Slope is 5/3
Now, you have an equation of y = 5/3x + b.
Since one of the points shows you what y equals when x=0, that is your y intercept.

The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete and I couldn't get the exact question online but let's reframe it and solve it.
The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes. This week, they paid $129 for 5 pies and 7 cakes.
Let's say the cost of pies is x
Let's say the cost of cake is y.
We'll then use the information given to make an equation which will be:
Last week they payed 204$ for 12 pies and 8 cakes. This will be:
12x + 8y = 204........ i
This week, they paid $129 or 5 pies and 7 cakes. This will be:
5x + 7y = 129 ........... ii
Therefore,
12x + 8y = 204........ i
5x + 7y = 129 .......... ii
Multiply equation i by 5
Multiply equation ii by 12
60x + 40y = 1020 ....... iii
60x + 84y = 1548 ........ iv
Subtract iii from iv.
44y = 528
y = 528/44
y = 12
The cost of cake is $12.
From equation i,
12x + 8y = 204
12x + 8(12) = 204
12x + 96 = 204
12x = 204 - 96
12x = 108
x = 108/12
x = 9
The cost of pies is $9.
0.326 as a fraction
Answers
Answer:
163/500
Step-by-step explanation:
we will not only clearly explain how to get the answer to 0.326 as a fraction, but also prove to you that our answer is correct.
First, note that 1000 multiplied by .326 will get rid of the decimal point. Therefore, make a fraction where the numerator is .326 times 1000 and denominator is 1000 like this:
.326 x 1000
1000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
326
1000
The greatest common factor of 326 and 1000 is 2, which means you can divide the numerator and denominator by 2 and keep the same value:
326 ÷ 2
1000 ÷ 2
And when calculating the numerator and denominator in our fraction above, we get .326 as a fraction in the simplest form possible:
.326 =

stay safe healthy and happy.Today's cafeteria specials at a high school in Westford are a deluxe turkey sandwich and a chef salad. During early lunch, the cafeteria sold 13 turkey sandwiches and 69 chef salads, for a total of $151. During the late lunch, 61 turkey sandwiches and 41 chef salads were sold, for a total of $143. How much does each item cost?
Answers
Answer:
chef salads = $2
turkey sandwiches = $1
Step-by-step explanation:
two equations can be derived from the question
13t + 69c = 151 eqn 1
61t + 41c = 143 eqn 2
t = turkey sandwiches
c = chef salads
multiply equation 1 by 61 and equation 2 by 13
793t + 4209c = 9211 eqn 3
793t + 533c = 1859 eqn 4
subtract equation 4 from 3
7352 = 3676c
c =2
substitute for c in equation 1
13t + 69(2) = 151
13t + 138 = 151
13t = 151 - 138
13t = 13
t = 1

Which is the better buy? 16 cards for $12.20 OR 14 cards for $10.90
Answers
Answer:
The better buy is 16 cards for $12.20 because
Step-by-step explanation:
You need to find the individual price for each card in the packet. So first lets do 16 cards for $12.20, you divide $12.20 by 16 to get the price of one card. 12.2/16=0.7625, or about $0.76. Next we do $10.90 divided by 14, 10.9/14=0.7785, or about $0.78, which means 16 cards for $12.20 is the better buy!

A sports company wants to package a ball with a 1.5-inch radius in sets of two. They have two options: a cylinder or a square prism.The company wants to use the package that has the least amount of wasted space. The company should choose
Answers
Answer:
The Company should choose to get the cylinder packages ( V = 42.39 in³ )
Step-by-step explanation:
The volume of a cylinder of radius of circumference 1.5 in and h = 1.5*4
h = 6 in is:
V(c) = π *r²*h = π * (1.5)²*6 = π *2.25*6
V(c) = 42.39 in³
Now V(p) = Square of the base ( of side 3 in) * h
h = 6 in
V(p) = (3)²*6
V(p) = 54 in³
If we compare these two volumes we see that the volume of the cylinder is small than that of the square prism
