The height of an airplane during a landing is given by 22,000+(−480t) where t is the time in minutes.

Literally plugging in the time for each value, we can plug in 5 for t to get
22000+(-480*5)=22000+(-2400)=22000-2400=19800
Plugging in 10, we get 22000+(-480*10)=22000-4800=17200. We can turn 22000+(-480*10) into 22000-(480*10) using the distributive property, and adding a negative number to something essentially means to subtract that number.

I challenge you to do t=15 and 20 on your own!

The area of a square garden is 50m^2. How long is the diagonal?

abruzzese [7]

Answer:

Adjacent length = √(50) m

Pythagorean theorem:

a^2 + b^2 = c^2

a = √(50) m

b = √(50) m

c^2 = √(50)^2 + √(50)^2

c^2 = 50 + 50

c^2 = 100

c = 10 m

Diagonal = 10 m

Solve 2Q + 5s=r for s and show ALL your steps.

likoan [24]

Answer:

2q-r= 5s

divide both sides by 5

2q-r/s =5s/5

therefore S= 2q-r/s

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the re

mina [271]

Answer:

Step-by-step explanation:

integrate with respect to x

Area is symmetric so will be twice the integral from zero to 1

( I cannot seem to figure out how to make the lower limit negative in this editor)

$A = 2\int\limits^1_0 {(x^2 + 3) - 4x^2} \, dx$ )

$A = 2\int\limits^1_0 {-3x^2 + 3} \, dx$

$A = 6\int\limits^1_0 {-x^2 + 1} \, dx$

A = 6(-⅓x³ + x) $\left \| {{x=1} \atop {x=0}} \right.$

A = 6((-⅓(1)³ + (1)) - (-⅓(0)³ + (0)))

A = 6(⅔)

A = 4 units²
