Suppose a flare is shot from the top of a 120 foot building at a speed of 160 feet per second. The equation h = ?16t + 160t + 120 models the h height at t seconds of the flare. How long will it take for the flare to hit the ground? (to the nearest tenth of a second)

The time taken for the flare to hit the ground is approximately 10.7 seconds.

Step-by-step explanation:

Given : Suppose a flare is shot from the top of a 120 foot building at a speed of 160 feet per second. The equation models the h height at t seconds of the flare.

To find : How long will it take for the flare to hit the ground?

Solution :

The equation   models the h height at t seconds of the flare.

The flare to hit the ground when h=0.

Substitute in the equation,

Applying quadratic formula,

Where, a=-16, b=160 and c=120

Reject the negative value.

Therefore, the time taken for the flare to hit the ground is approximately 10.7 seconds.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
