What is the missing dimension of a parallelogram if h=5 1/4feet and A=12feet

Answers

Answer 1

Answer: The missing is the base
A=bh
12= 5.25b
Divide both sides by 5.25
b=2.29 ft

Step-by-step explanation:

8. B is the midpoint of AD

A (x,y)

D( -1,3) B ( (x-1)/2, (y+3)/2) and B ( 1,1)

then (x-1)/2=1, x-1=2 ( +1) , x= 2+1, x=3

(y+3)/2=1, y+3=2 ( -3) y=2-3, y= -1

then A (3, -1)

9. (-8,3)

(s,3) the midpoint (0,u)

then (s-8)/2=0, s=8

(3+3)/2=u, u=6/2, u= 3

10. a=1 ( the y coordinate is the same as the midpoint

A(3,1)

B(x,y) the midpoint (5,1)

(3+x)/2=5, 3+x=10 , x=10-3, x=7

(y+1)/2=1, y+1=2,y=2-1, y=1

B(7,1)

Answer: 3x+11

Step-by-step explanation:

f(x) = 3x - 4

f(x + 5) = 3(x + 5) - 4 = 3x + 15 - 4 = 3x + 11

An air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute. Select all that apply to this situation. The slope is 1000 ft per minute. The balloon is falling at 1000 ft per minute.

The y-intercept is 50 ft. The balloon falls at a rate of 50 ft per minute.

The y-intercept is 1000 ft. The balloon begins to from an initial height of 1000 ft.

The slope is -50 ft per minute. The balloon is falling at 50 ft per minute.

It will take the balloon 20 minutes to reach the ground.

Answers

Answer:

The correct options are 3, 4 and 5.

Step-by-step explanation:

It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.

It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).

The ball falls at a rate of 50 ft per minute. So, the rate of change is

$m=-50$

The height of balloon is defined as

$h(x)=-50x+1000$ $[\because y=mx+b]$

Where, x is time in minutes.

The balloon will reach the ground when h(x)=0

$0=-50x+1000$

$50x=1000$

$x=20$

Therefore the options 3, 4 and 5 are correct.
