Step-by-step explanation:
Let's look at A(x) and see how it is different from f(x)
- it is shifted downwards by 8 units
- it is not shifted to the left or the right
Therefore A(x) = f(x) - 8
Let's look at B(x) and see how it is different from f(x)
- it is not shifted downwards or upwards
- it is shifted to the left 7 units
Therefore B(x) = f(x + 7)
Let's look at C(x) and see how it is different from f(x)
- it is shifted upwards by 4 units
- it is shifted to right by 5 units
Therefore C(x) = f(x - 5) + 4
Let's look at D(x) and see how it is different from f(x)
- it is not shifted downwards or upwards
- it is not shifted to right by 12 units
Therefore D(x) = f(x - 12)
8 * 24 feet = 192 sq feet per 5 hours
12* 36 = 432 square feet
432 is 2.25 times the area of 192 square feet
So, it takes 5 * 2.25 = 11.25 hours
Answer:
16cm
Step-by-step explanation:
Let W be width
Width=W
Length=2W
Perimeter=(Length+Width)×2
48=(2W+W)×2
48=6W
W=8cm
Therefore length is 8×2=16cm
Answer:
$16.67
Step-by-step explanation:
-Let Ben's expenditure be X,
#Ava's expenditure being three times Ben will be 3X, and half as much as Cora(2X)
-Given that the total expenditure was 50, Cora's portion is calculated as :
Hence, Cora's expenditure is $16.67
