No. Because it repeats 1(aka the domain) twice. When there is two same x values than isn’t a function.
Answer:
Width = 18 inches
Length = 59 inches
Step-by-step explanation:
The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions
Perimeter of a rectangle = 2L + 2W
The length of a rectangle is five more than triple the width.
L = Length = 5 + 3W
W = Width
If the perimeter is 154 inches, what are the dimensions
Hence,
154 = 2L + 2W
154 = 2(5 + 3W ) + 2W
154 = 10 + 6W + 2W
Collect like terms
154 - 10 = 8W
144 = 8W
W = 144/8
W = 18 inches
Length = 5 + 3W
Length = 5 + 3(18)
Length = 5 + 54
Length = 59 inches
Answer:
The focii are 8 feet apart
Step-by-step explanation:
You can use the formula
F = √(a^2 - b^2) where F is the distance of the focii from the center , a = length of the semi major axis and b = length of the semi minor axis)
So here it is √(5^2 - 3^2)
= √16 = 4
So the distance is 2*4 = 8
