Ben dives from a 10-foot platform. the equation h = -16 t 2 27t 10models the dive. how long will it take ben to reach the water?

1 answer:

3 0

So i'm assuming your eqtn is h = -16t^2 + 27t + 10
and we're looking for t = ? when h = 0

=> 16t^2 - 27t - 10 = 0
(16t + 5)(t - 2) = 0

t = 2 and t = -5/16

answer 2 seconds

1. Which of the following is the slope-intercept form of 6x + 2y = 28?

Andru [333]

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

6x + 2y = 28 ( subtract 6x from both sides )

2y = - 6x + 28 ( divide the terms by 2 )

y = - 3x + 14 ← in slope- intercept form

the jars of paint in the art room have different amounts of paint. The green paint jar is 4/8 full. The purple paint jar is 4/6

BartSMP [9]

The green paint jar is less full. if the denominator is the smaller, and the numerator is the same, the one with the bigger denominator is smaller
