Answer:

The function is increasing from x = 0 to x = 1.

Step-by-step explanation:

A <u>function</u> is increasing when the <u>y-value increases</u> as the <u>x-value increases</u>.

A <u>function</u> is decreasing when the <u>y-value decreases</u> as the <u>x-value increases</u>.

From x = -2 to x = -1 the function is decreasing as the y-value decreases as the x-value increases:

x-value -2 to -1 → increase
y-value 2 to 0 → decrease

From x = -1 to x = 0 the function is increasing as the y-value increases as the x-value increase:

x-value -1 to 0 → increase
y-value 0 to 2 → increase

From x = 0 to x = 1 the function is increasing as the y-value increases as the x-value increase:

x-value 0 to 1 → increase
y-value 2 to 8 → increase

Which of the following is the best definition of vertical angles?

Lilit [14]

Step-by-step explanation:

Very quick and effortless example of vertical angles in the attached image. When 2 straight lines intersect, the 2 angles opposite each other at that point are vertical angles, and they are always congruent.

I'd say it's the 3rd option:

"Vertical angles are a pair of non-adjacent angles formed by two intersecting lines."

but any of the first three could be technically true really. Adjacent angles are 2 angles that share a side, and vertical angles cannot share one.

Find the perimeter of a

Serhud [2]

Step-by-step explanation:

length of a rectangle = (3x+4)

breadth of a rectangle =(2x-1)

perimeter of a rectangle =?

we know that,

perimeter of a rectangle=2 (length+breadth)

2 (3x+4)+(2x-1)

(6x+8)+(4x-4)

(6x+4x)+(4+8)

10x+12

x=12-10=2

x=2#

Margie is standing on a bridge looking at the river below. She throws a rock over the bridge with an initial

Marina CMI [18]

<h2>Explanation:</h2><h2></h2>

Here we know that Margie is standing on a bridge looking at the river. She throws a rock over the bridge with an initial velocity of 60 ft/sec. The height, h, of the rock at the rime t seconds after it was thrown can be modeled by the equation:

$h(t) = -16t^2+60t+72$

To calculate how long will it take for the rock to reach the surface of the water, we need to set $h(t)=0$ . So:

$0 = -16t^2+60t+72 \\ \\ \\ \text{Using quadratic formula}: \\ \\ t=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \\ a=-16 \\ \\ b=60 \\ \\ c=72 \\ \\ \\ t=\frac{-60 \pm \sqrt{60^2-4(-16)(72)}}{2(-16)} \\ \\ t=\frac{-60 \pm \sqrt{60^2-4(-16)(72)}}{2(-16)} \\ \\ t=\frac{-60 \pm \sqrt{8208}}{-32} \\ \\ t_{1}=4.70 \\ \\ t_{2}=-0.95$

Given that time can't be negative, we just choose the positive value. Therefore, <em>it will take 4.70 seconds for the rock to reach the surface water.</em>
