Answer:

Step-by-step explanation:

Given that a rocket path is given by

$h(x) = -4x^2 + 16x$

When it hits the ground h(x) =0

Hence we get

$-4x^2 + 16x=0\\x=0, 4$

i.e. after 4 minutes the rocket hits the ground

2) Given that

$s(t) = -16t^2 + 48t + 280.$

We have to find time t when height >280

$s(t) = -16t^2 + 48t + 280>280\\\\t=0, 3$

Between 0 and 3 seconds the object would be above the building.

1.) You plug a number into the variable x. Then you will solve the equation for h(x) to find the time it takes for the rocket to travel the path given.

Select the best attribute for the angle pair formed by two parallel lines intersected

Inga [223]

Answer:

Corresponding Angles sum to 180°

Step-by-step explanation:

If a pair of parallel lines is cut by transversal that is not perpendicular to the parallel lines as shwon in the figures (attached below), then;

Four angles are acute, and four are obtuse.

All four acute angles are equal: 2=3=6=7
All four obtuse angles are equal: 1=4=5=8
The sum of acute and obtuse angles is 180: for example, 1+2=180, 3+4=180, 5+6=180, 7+8=180

so the best attribute for the angle pair formed by two parallel lines intersected by a transversal is that Corresponding Angles sum to 180°.
