Rearrange your equation from part A by setting it equal to 0 and substituting y for 0. Then write the equation in the form y = (x – h)2 – c.
Answer:
y = (x - 1)^2 - 8
Step-by-step explanation:
Your answer from part A should be: (x - 1)^2 = 8
You are simply changing the format of the equation from
0 = (x - 1)^2 - 8 to y = (x - 1)^2 - 8
Hope this helps!
Answer:
y = (x-1)² - 8
Step-by-step explanation:
The response from part A is (x – 1)2 = 8, where h = 1 and c = 8.
Set the equation equal to 0:
0 = (x – 1)2 – 8.
Substitute y for 0 and keep the equation rewritten in the form y = (x – h)2 – c:
y = (x – 1)2 – 8.
A pack of 6 cans of pop costs £1.80. A pack of 10 cans of pop costs £3.50.
Which one should you buy?
Let us look at the cost per can of both packs.
Cost of can in 6-pack = 1.80/6
= £0.30
Cost of can in 10-pack = 3.50/10
= £0.35
Since the cost of a can in the 6-pack is cheaper, it would be better to buy the 6-pack if you were looking to save money.

The mass of the cylinder is 50,000 g. Find the density of the cylinder to the nearest tenth
answer choices
0.7 g/mm3
81.2 g/mm3
2.7 g/mm3
0.4 g/mm3
Answer:
Density of the Cylinder = 2.7 g/mm³
Step-by-step explanation:
Density of a cylinder is calculated using the formula =
Mass of the Cylinder ÷ Volume of the Cylinder
Step 1
The First step is to find the Volume of the Cylinder.
Volume of a Cylinder = πr²h
In the attached image , we are given:
Diameter of the Cylinder = 28mm
Radius of the Cylinder = Diameter ÷ 2 = 28mm ÷ 2
Radius of the Cylinder (r) = 14mm
Height of the Cylinder (h) = 30mm
The Volume of the Cylinder = πr²h
= π × (14mm)² × 30mm
= 18472.564803 mm³
Step 2
The second step would be to find the Density of the Cylinder.
Density of the Cylinder = Mass of the Cylinder ÷ Volume of the Cylinder
Mass of the Cylinder = 50,000g
Volume of the Cylinder = 18472.564803 mm³
Density of the Cylinder = 50,000g ÷ 18472.564803 mm³
= 2.7067167193 g /mm³
Approximately the Density of the Cylinder = 2.7 g/mm³

The perimeter of a rectangle is 128 cm. The length of the rectangle is three times longer than the width. What is the length and width of the rectangle?
Answer:
l=16 cm
w=48 cm
Step-by-step explanation:
perimeter of rectangle formula:
2l+2w
where
3w=l
and w=w
so
2(3w)+2w=128
6w+2w=128
8w=128
w=16
now substitute 16:
2l+2(16)=128
2l+32=128
2l=96
l=48
The length is 48 cm and width is 16 cm.
what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values. . In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Jason owns a food truck that sells tacos and burritos. He sells each taco for $4.75 and each burrito for $7.50. Yesterday Jason made a total of $790 in revenue from all burrito and taco sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system.
let t be the number of tacos sold
let b be the number of burritos sold
Step-by-step explanation:
b=2t
4.75t+7.50b=790
To solve the problem, set up two variables T and B for the number of tacos and burritos sold. Two equations are formed: B = 2T (since twice as many burritos as tacos were sold) and 4.75T + 7.50B = 790 (from the total revenue). Solve these to find T and B.
Explanation:To determine the number of tacos and burritos sold by Jason's food truck, we need to establish two variables: let T represent the number of tacos sold, and let B represent the number of burritos sold. Given that burritos are sold at a ratio of two to every one taco, we can express this relationship with the equation B = 2T. Next, using the given prices of tacos ($4.75) and burritos ($7.50), along with the total revenue of $790, we can write the budget constraint equation as 4.75T + 7.50B = 790. These two equations together form the system of equations that can be solved to find the number of tacos (T) and burritos (B) sold.
Find the missing factor. 5y^2+4y-1=(5y-1)()
Answer:
(5y−1)(y+1)
Step-by-step explanation:
Answer:
(y + 1 )
Step-by-step explanation:
Given
5y² + 4y - 1
Consider the factors of the product of the y² term and the y- term which sum to give the coefficient of the y- term
product = 5 × - 1 = - 5 and sum = + 4
The factors are + 5 and - 1
Use these factors to split the y- term
5y² + 5y - y - 1 ( factor the first/second and third/fourth terms )
= 5y(y + 1) - 1(y + 1) ← factor out (y + 1) from each term
= (y + 1)(5y - 1)
The missing factor is (y + 1)
Find the circumference and area of a circle whose radius is 12.4 cm.Give your answer to the nearest centimeter (whole #). Circumference = cm Area = cm2
Final answer:
The circumference of the circle is approximately 78 cm and the area of the circle is approximately 484 cm².
Explanation:
The circumference of a circle can be found by using the formula:
Circumference = 2πr, where r is the radius of the circle.
Given that the radius is 12.4 cm, we can substitute this value into the formula:
Circumference = 2π(12.4 cm)
Using an approximation of π as 3.14, the calculation becomes:
Circumference = 2(3.14)(12.4 cm) = 77.9 cm
Therefore, the circumference of the circle is approximately 78 cm (to the nearest whole number).
The area of a circle can be found by using the formula:
Area = πr²
Substituting the given radius into the formula:
Area = 3.14(12.4 cm)² = 483.864 cm²
Therefore, the area of the circle is approximately 484 cm² (to the nearest whole number).

He has between 10 and 20 batteries. He counts the batteries by putting them into piles of 4 and finds that he has 3 left over. He then counted them by putting them into piles of 3 and found that he had one left over. How many batteries does he have?
Answer:
15 batteries
Step-by-step explanation:
If he puts the batteries in piles of 4, and there is 3 left over, the number of batteries he can have is:
2 piles: 4*2 + 3 = 11
3 piles: 4*3 + 3 = 15
4 piles: 4*4 + 3 = 19
Then, when he puts in piles of 3, there is no batteries left over, so the number of batteries is a multiple of 3.
From the 3 possibilities above (11, 15 and 19), only the number 15 is a multiple of 3, so the number of batteries is 15.
