The volume of the bedroom is 11 x 10 x 10 = 1100 cubic feet.
The volume of the den is double, so 1100 x 2 = 2200 cubic feet.
Divide the volume of the den by the height, since it is the same as the bedroom, this will give you the area:
2200 / 10 = 220 square feet.
Two sets of numbers that could equal 220 are 22 x 10 or 22 x 11
The room can be 20 ft by 10 ft or 22 ft by 11 ft and the volume is 2200 cubic feet.
Answer:
( 2,5)
Step-by-step explanation:
The solution is where the two graphs intersect
The graphs intersect at x = 2 and y = 5
( 2,5) is the solution to the system
Answer:
a) -2 and 4
b) function 2
Step-by-step explanation:
a)
rate of change is rise over run: change in y / change in x.
function 1:
- i will use first 2 pairs of data
- change in y: 5 - 3 = 2
- change in x: -2 - (-1) = -1
-rate of change = 2/-1 = -2
function 2:
- same idea, but find two points on the graph!
- (0,4) and (-1,0) for example! pick easy points
- change in y is 4. chabge in x is 1
- rate of change is 4
b)
function b has greatest rate of change. 4 > -2
For it’s A= 0.01
And for B it’s B= 9800
