Answer:

13,200 feet

Step-by-step explanation:

So, the rocket starts descending at a given rate and time, so we first need to find the length it passed during that descent.

Length equals to speed multiplied with time:

s = v • t

since speed is given in feet per second, we need to convert minutes to seconds; if one minute has 60 seconds, then two minutes have 120 seconds.

s = 15 feet/s • 120 s

s = 1800 feet

So, the rocket descended 1800 feet, but it still has 11,400 feet to the Moon's surface. That means that the rocket was on 11,400 + 1,800 = 13,200 feet elevation when it started to drop.

Answer:

y > -2x + 2

Step-by-step explanation:

The dashed line tells us the answer doesNOT have the "or=to" under the inequality symbol. Then the y-intercept is positive 2. So it must be

y > -2x + 2

see image

Look at the y-intercept and think of up/down instead of left/right on the shading and then you can see whether its < or >

The length of a rectangle is 10 inches more than 4 times the width. If the area of the rectangle is 150 square
Elena-2011 [213]

Answer:

width = 8, length = 42

Step-by-step explanation:

Let x = width, then length = 4x+10.

A = l x w

336 = x(4x+10) put into standard form

4x2 + 10x - 336 = 0 divide by 2

2x2 + 5x - 168 = 0 and solve using the quadratic formula and get

-21/2 and 8, the neg answer will not work, so the width = 8, length = 42
