Write the slope-intercept form of the equation of the line through the given point with the given

sineoko [7]

Answer:

y = 9x - 5

Step-by-step explanation:

The slope is already given, so we just need to find the y-intercept.

Plug in 9 for m, 1 for x, and 4 for y in the equation y = mx + b.

4 = 9(1) + b

b = -5

Now that we know the y-intercept, we can construct the equation of the line.

y = 9x - 5

On a coordinate plane, triangle A B C is shifted 4 units to the right and 2 units up to form triangle A prime B prime C prime. I

zheka24 [161]

Answer:

(x, y) ⟶ (x + 4, y + 2)

Step-by-step explanation:

If you shift a point four units to the right, x ⟶ x + 4.

If you shift it up two units, y ⟶ y + 2.

If you combine the two shifts into one transformation, the rule becomes

(x, y) ⟶ (x + 4, y + 2)

A person standing close to the edge on top of a 112-foot building throws a ball vertically upward. The quadratic function h ( t

LenaWriter [7]

Answer:

the maximum height of the ball= 256 feet

7 seconds

Step-by-step explanation:

The quadratic function h ( t ) = − 16t^2 + 96t + 112 models the ball's height about the ground, h ( t ) , in feet, t seconds after it was thrown.

a= -16 , b= 96 and c= 112

To find maximum height , we find vertex

$x= \frac{-b}{2a}=\frac{-96}{2(-16)}= 3$

Now plug in 3 for 't' in h(t)

$h(t) = -16t^2 + 96t + 112$

$h(t) = -16(3)^2 + 96(3)+ 112=256$

Hence vertex is (3, 256)

the maximum height of the ball= 256 feet

(b) when the ball hits the ground then height becomes 0

so we plug in 0 for h(t) and solve for t

$0 = -16t^2 + 96t + 112$

Apply quadratic formula

$t=\frac{-b+-\sqrt{b^2-4ac}}{2a}$

Plug in all the values a= -16 , b= 96 and c= 112

$t=\frac{-96+-\sqrt{96^2-4(-16)(112)}}{2(-16)}$

t= -1 and t= 7

time cannot be negative. So it will take 7 second to hit the ground.
