On a given dive, a platform diver’s body follows a path that can be modeled by the equation d = −4t^2 + 2t + 6, where d represen
ludmilkaskok [199]

Answer:

t = 1.5 seconds

Step-by-step explanation:

Given that d = −4t^2 + 2t + 6,

where d = distance above the water and

t = seconds.

Let assume that it's a perfect parabola

At the symmetry

t = -b/2a

Where a = -4, b = 2

t = -2/2(-4)

t = 1/4

To determine how long it will take a diver to reach the water’s surface

d = −4t^2 + 2t + 6

At water surface d =0

4t^2 - 2t - 6 = 0

Factorizing the above equation leads to

4t^2 + 4t - 6t - 6 = 0

4t(t + 1) -6(t + 1) = 0

4t - 6 =0

4t = 6

t = 6/4= 3/2 = 1.5 seconds

Since t can't be negative so we ignore the second factor.

Karl rides his bicycle 120 feet in 10 seconds. How many feet does he ride in 1 minute
Bumek [7]

A minute is 6 times as long as 10 seconds, so we expect Karl will ride 6 times as far.

\dfrac{120\,ft}{10\,s}=\dfrac{120\,ft}{10\,s}\cdot\dfrac{60\,s}{1\,min}=\dfrac{720\,ft}{1\,min}

Karl rides 720 ft in 1 minute.

Suppose Mahkah makes a Native American lunch in a pot that is shaped like a right cylinder. If
Harman [31]

The pot can hold 5.23 quarts

Step-by-step explanation:

  • Step 1: Find the volume of the right cylinder shaped pot.

Diameter of the pot = 8 in

⇒ Radius = 4 in

Height = 6 in

⇒ Volume of the pot = πr²h = 3.14 × 4² × 6

                                   = 301.44 in³

  • Step 2: Convert inches to quarts.

1 in³ = 0.017316 liquid quarts

⇒ 301.44 in³ = 301.44 × 0.017316 = 5.23 quarts
