The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25
Answer:
The domain for A is 0, 1, 2, 3 and the range is 0, 5, 10, 15
and the domain for B is 2, 2, 4, 4 and the range is 4, 3, 2, 1
Only A is a function because for the same input value in B, there is two different output values which is not possible.
Step-by-step explanation:
I just wanna let you know so you don't waste any more points for us, but the domain is the x-values/ input/ stuff on the left of a given point. The range is the y-values, the output, and the stuff on the right side of a given point. So on (1, 7) for example, the 1 would be the domain number and the 7 would be the range number.
The y-axis values are the output/range and the x-axis values are the input/domain.
Hope this helps bro
Answer:
d= -2
Step-by-step explanation:
7 + 4d + 5d = 7d + 3
Combine like terms
7+9d = 7d+3
Subtract 7d from each side
7+9d-7d = 7d-7d+3
2d +7 = 3
Subtract 7 from each side
2d+7-7 = 3-7
2d = -4
Divide each side by 2
2d/2 = -4/2
d = -2
Answer:
Step-by-step explanation:
Income = 12h - 4.5c
h = 8
c = 2
Income = 12*8 - 4.5*2
Income = 96 - 9
Income = 87
Answer: 158.53 cm
Step-by-step explanation:
We know that the ends of a fishing line spool are circular in shape.
Given : The area of an end of fishing line spool =
(1)
Area of a circle =
(2)
Circumference of a circle =
(3)
, where r is radius of the circle.
From (1) and (2), we have
Circumference of fishing spool =
(using (3))

i.e. Fishing spool required to wind around the spool one time 
⇒ Fishing spool required to wind around the spool 10 times 
Hence, you need 158.53 cm or about 159 cm of fishing line to wind around the spool 10 times.
