An airplane flying at attitude of 32,000 feet descends at a rate of 1,300 feet per minute. If the plane descends for 15 minutes,

Furkat [3]

Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)

Write an equation in slope-intercept form of the line that passes through the points (-6, -10) and (1,4).

vova2212 [387]

Answer:

y = mx + 1/2

Step-by-step explanation:

(x,y)

- Plot each point on a graph

- The line should go from the bottom left (-6,-10) to the top right (1,4)

- Count how many spaces are on the y-axis from -6 to 1 for numerator

- Count how many spaces are on the x-axis from -10 to 4 for denominator

- Positive slope

- Slope = 7/14

- Simplify to 1/2

A2+5a+6=0<br><img src="https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%205a%20%2B%206%20%3D%200" id="TexFormula1" title="

Katarina [22]

we are given

$a^2+5a+6=0$

we can use factoring formula

$a^2-(m+n)a+mn=(a-m)(a-n)$

we can compare

and we get

$m+n=-5$

$mn=6$

now, we can solve for m and n

and we get

$m=-3 , n=-2$

now, we can use formula

and we get

$a^2+5a+6=(a+3)(a+2)$

now, we can set it equal to 0

$a^2+5a+6=(a+3)(a+2)=0$

$(a+3)=0$

$a=-3$

$a+2=0$

$a=-2$

so, we will get

$a=-2,a=-3$ .............Answer

Virginia Beach is 10 miles wide and 30 miles long. If one inch of rain falls on Virginia Beach, how many cubic feet of rain fell

Arte-miy333 [17]

1 mile = 5280 feet.

Convert the dimensions to feet:

10 miles = 5280 x 10 = 52,800 feet

30 miles = 5280 x 30 = 158,400 feet

Multiply together to get the area:

52,800 x 158,400 = 8,363,520,000 square feet.

1 inch = 1/12 of a foot.

Multiply the area by 1/12 for the volume of rain:

8,363,520,000 x 1/12 = 696,960,000 cubic feet.
