Vertex Form

DerKrebs [107]

If you want to express the vertex form of an equation you have to know that the vertex form of a parabola’s equation can be expressed as: y = a(x - h)² + k. The way you know how the parabola will look like is:

If a is positive then the parabola opens upwards like a U. If a is a negative number, then the graph will open downwards like an upside down U.

I hope it helps, Regards.

Mike scored 38 points in the first half of the basketball game, and he scored p points in the second half of the game. Write an

Vladimir [108]

38 + p

He scored 58 points total if she scored 20 in the second half

Adding up the number of the points earned in the first half (38) and the number of points earned in the second half (p) will give you the total points.

If he scored 20 points in the second half of the game, then you can change the expression to:

38 + 20

Because now you know what he scored in both the first half and the second half. Then you can add them together to get the answer of 58

Elena L [17]

Answer:

Part A: What would be worth the car's worth in 2 years?

V(2) = $ 391,114.50

Part B. In how many years will the car be worth $325,000?

t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days

Step-by-step explanation:

Part A: What would be worth the car's worth in 2 years?

If V(t) = 420,000(0.965) ^t, therefore:

V(2) = 420,000(0.965)²

V(2) = 420,000 * 0.931225

V(2) = $ 391,114.50

Part B. In how many years will the car be worth $325,000?

If V(t) = 420,000(0.965) ^t, therefore:

325,000 = 420,000(0.965) ^t

325,000/420,000 = (0.965) ^t

0.7738 = 0.965^t

t = log 0.965(0.7738)

t = log 0.7738/log 0.965

t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days

0.2 years = 0.2 * 12 = 2.4 months
