Answer:
C - f(t) = 4(t − 1)^2 + 2; the minimum height of the roller coaster is 2 meters from the ground.
Step-by-step explanation:
Here we're asked to rewrite the given equation f(t) = 4t^2 − 8t + 6 in the form f(t) = a(t - h)^2 + k (which is known as the "vertex form of the equation of a parabola.") Here (h, k) is the vertex and a is a scale factor.
Let's begin by factoring 4 out of all three terms:
f(t) = 4 [ t^2 - 2t + 6/4 ]
Next, we must "complete the square" of t^2 - 2t + 6/4; in other words, we must re-write this expression in the form (t - h)^2 + k.
(To be continued)
Answer:
I believe that the answer is 95 meters.
Explanation:
Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.
<em>Area of a rectangle/square - </em><em>l x w</em>
<em />
In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.
<em>6840 ÷ 72 = </em><em>95</em>
You can always double check to see if the number is correct.
<em>A = l x w</em>
<em>= 72 m x 95 m</em>
<em>= </em><em>6840 m</em>²
Really hope this helped. :)
