Jon is launching rockets in an open field. The path of the rocket can be modeled by the quadratic function h(t) = -16t^2 + 96t,

IrinaVladis [17]

It will reach 80 feet for the second time after 5 seconds.

We set the equation equal to 80 feet:
80= -16t² + 96t

When solving quadratics, we want it equal to 0, so we subtract 80 from both sides:
80-80= -16t² + 96t - 80
0= -16t² + 96t - 80

We use the quadratic formula to solve:
$t=\frac{-96\pm \sqrt{96^2-4(-16)(-80)}}{2(-16)}
\\
\\t=\frac{-96\pm \sqrt{9216-5120}}{-32}
\\
\\t=\frac{-96\pm \sqrt{4096}}{-32}
\\
\\t=\frac{-96\pm 64}{-32}
\\
\\t=\frac{-96+64}{-32} \text{ or } 0=\frac{-96-64}{-32}
\\
\\t=1 \text{ or } t=5$

Could someone help me answer this question because I really don't know how to get the answer or solve it thanks

A central angle is an angle made by 2 radii. Seeing as they want the measure of the angle that represents industry pollution, that would be 40% of the total 360 degrees.
40% = 0.4
0.4 × 360 = 144
The measure is 144 degrees.

What is an equation for the line that passes through (-2,-3) with a slope of -1/2?

Crazy boy [7]

Answer:

C

Step-by-step explanation:

To write the equation of a line use the point slope form of a line substituting m = -1/2 and the point (-2,-3).

$y -y_1 = m(x-x_1)\\y --3=-\frac{1}{2}(x--2)\\y+3 = -\frac{1}{2}(x+2)$

Convert to standard form by applying the distributive property and rearranging the terms.

$y + 3 = -\frac{1}{2}(x+2)\\y+3 = -\frac{1}{2}x -1\\2y + 6 = -x -2\\x+2y + 6 = -2\\x + 2y = -8$

The equation x +2y = -8 is the same equation as 4y + 2x = -16 just doubled----> 2x + 4y = -16

X2 + 2y ÷ w + 3z for w = 2, x = 5, y = 8, and z = 3?

melisa1 [442]

Step-by-step explanation:

w = 2

x = 5

y = 8

z = 3

= x² + 2y ÷ w + 3z

= (5)² + 2(8) ÷ (2) + 3(3)

= 25 + 16 ÷ 2 + 9

= 25 + 8 + 9

= 42
