4y^2-x-24y+30=0
And this Circle equation in standard form.
2x^2+2y^2-18x-10y+7=0
Answer:
[tex]x=4y^2-24y+30[/tex]
[tex](x-4.5)^2+(y-2.5)^2=23[/tex]
Step-by-step explanation:
Standard form of a sideways parabola: [tex]x=ay^2+by+c[/tex]
Given equation:
[tex]4y^2-x-24y+30=0[/tex]
Add x to both sides:
[tex]4y^2-24y+30=x[/tex]
[tex]\implies x=4y^2-24y+30[/tex]
--------------------------------------------------------------------------------------------
Standard form of circle equation
[tex](x-a)^2+(y-b)^2=r^2[/tex]

How to find the side length of a similar triangle?In mathematics, two triangles are said to be similar provided that they have the same ratio of corresponding sides and equal pair of corresponding angles.
Now, from the given image, we can see that DE bisects AC into 2 equal parts and by virtue of the concept of similar triangles, we can say that;
DE/BC = 1/2
We are given;
DE = x + 1
BC = 4x - 6
Thus;
(x + 1)/(4x - 6) = 1/2
Cross multiply to get;
2x + 2 = 4x - 6
4x - 2x = 6 + 2
2x = 8
x = 4
That value of x is the missing value required in conclusion.

Anthony is calculating how high a ball is thrown. He has determined the function h(t) = -16t² + 20t + 4 to
represent the height of the ball in feet over t seconds. He wants his final answer to be in inches. He knows that the
function N(f) = 12f will convert f feet into inches. Compose the functions so that he has one equation to determine
the number of inches high the ball will be over t seconds.
Answer:
N(t) = -192t² +240t +48
Step-by-step explanation:
The composition of functions will be created by using the height function as the argument of the units conversion function.

so 72= 4l
divide through by 4
length=18
Answer:
24 inches x 12 inchesStep-by-step explanation:
Perimeter
2l + 2w = 72l + w = 36Area
lw = 288From the perimeter
Reaarrange the equation of the perimeter so that it equates to one of the variablesl = 36 - wSubstituting in the area formula
(36 - w)(w) = 28836w - w² = 288w² - 36w + 288 = 0w² - 24w - 12w + 288 = 0w(w - 24) - 12(w - 24) = 0(w - 12)(w - 24) = 0w = 24, 12The greater value of the two will be the length, and lesser value will be the width.

Think you can figure out the area of this unique shape?
Answer:
20
Step-by-step explanation:
To find the area, separate the unique shape into 3 rectangles. Then, solve for the area of those three rectangles:
2 x 4 = 8
2 x 3 = 6
6 x 1 = 6
Then, add up all of those areas to find the total area of the unique shape:
8 + 6 + 6 = 20
The area of the unique shape is 20.

Give your answer as a decimal, to two places
Answer:
(34.15, 47.85)
Step-by-step explanation:
[tex]n = (\frac{z*stddev}{ME} )^{2}[/tex]
stddev = 11.9
z = invNorm(
area = (1 + confidence interval)/2
mean = 0
stddev = 1

n = 20
square root both sides

multiply both sides by ME, divide both sides by √20 to isolate ME
ME = 2.576 * 11.9/√20

Natalie makes potato cakes in a restaurant.
She mixes potato, cheese and onion so that
weight of potato:weight of cheese :weight of onion = 9: 2:1
Natalie needs to make 6000g of potato cakes.
Cheese costs £2.25 for 175 g.
Work out the cost of the cheese needed to make 6000g of potato cakes
A ratio shows us the number of times a number contains another number. The cost of cheese that is needed to make 6000g of potato cake is £12.86.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the ratio of the ingredients is,
weight of potato: weight of cheese: weight of onion = 9: 2:1
Let the ingredients be mixed in the quantity 9x, 2x, and 1x, for 6000g of potato cake. Therefore, the value of x can be written as,
[tex]9x+2x+1x = 6000\\\\12x = 6000\\\\x = 500[/tex]
Hence, the value of x is 500.
Thus, the amount of cheese that will be needed is 2x,
[tex]2x = 2 \times (500) = 1000g[/tex]
Given that the cost of 175g of cheese is £2.25, therefore, the cost of 1g of cheese will be,
[tex]\text{Cost of 1g cheese} = \£\dfrac{ 2.25}{175}[/tex]
Now, the cost of 1000g of cheese will be,
[tex]\text{Cost of 1000g cheese} = 1000\times \£\dfrac{ 2.25}{175} = \£12.86[/tex]
Hence, the cost of cheese that is needed to make 6000g of potato cake is £12.86.
