C. x = y2 - 8y + 43
D. x = y2 + y + 15
Answers
Answer:
Option C. x = y² - 8y + 43
Step-by-step explanation:
The vertex form of the equation of a parabola is x = (y - 4)² + 27
We have to find the standard form of the equation which is in the form of x = ay² + by + c
To get the standard form of the equation we will simplify the vertex form of the equation.
x = (y - 4)² + 27
x = y² + 16 - 8y + 27
x = y² - 8y + 43
This matches with option C. x = y² - 8y + 43

Let p represent the cost of pretzels and L the cost of a lemonade.
From the second paragraph,
2p+ L= 5.75
From the equation above, the cost of a pretzel p can be expressed as:
2p= 5.75 - L
p= 5.75/2 - l/2
The cost of two lemonades exceeds that of a pretzel by 0.25:
2 L= 5.75/2 -L/2+0.25
Solving this gives:
L=1.05
Then replace the value of L in p= 5.75/2 - L/2
This gives the value of a pretzel.
Final answer:
By using a system of equations, we can find that the cost of a pretzel is approximately $1.83.
Explanation:
This question can be solved using a system of linear equations. Let's define P as the cost of a pretzel and L as the cost of lemonade. So from the problem, we have 2 equations: 2P + L=$5.75 and L= P + $0.25.
Now, we can substitute the equation for L into the first equation to get: 2P + (P + $0.25) = $5.75, which simplifies to 3P + $0.25 = $5.75. Subtracting $0.25 from both sides gives 3P = $5.50. Dividing by 3 will then give the cost of a pretzel, so P = $5.50/3 = $1.83.

radius of the cone = half the radius of the cylinder
height of the cone = radius of the cylinder
Volume of the cone = π r² h/3
let x be the radius of the cylinder
V = 3.14 * (x/2)² * x/3
V = 3.14 * (x/2 * x/2) * x/3
V = 3.14 * x²/4 * x/3
V = 3.14x³ / 12
The radius of the cylinder is r.
The radius of the cone is half of the radius of the cylinder: r/2.
The height of the cone is equal to the radius of the cylinder: r.
If the volume of the cone is π r²h/3, and the radius of the cone is r/2, and the height of the cone is r, then:
V = π × r² × h / 3
V = π × (r/2)² × r / 3
V = π × r²/4 × r / 3
V = π r³/12
