The answer is A) h(x)= 1/2x-1/2
14.45 times 0.20 = 2.89
14.45 - 2.89 = $11.56 after sale
$20 - $11.56 = $8.44 in change
Answer:
50 feet long
87.5 feet wide
350 feet high
Step-by-step explanation:
8 inches : 250 feet
1 inch : 250/8 feet
250/8 = 31.25
Length: 31.25 × 1.6 = 50 feet
Width: 31.25 × 2.8 = 87.5 feet
Height: 31.25 × 11.2 = 350 feet
Answer:
W₂ is three times W₁ (W₂ = 3W₁)
Step-by-step explanation:
Applying,
W = ke²/2............. Equation 1
Where W = workdone in stretching the spring, k = spring constant, e = extension.
For W₁,
W₁ = ke₁²/2
Given: e₁ = 30-20 = 10 cm = 0.1 m
Substitute these value into equation 1
W₁ = k(0.1²)/2
W₁ = 0.005k Joules
For W₂,
W₂ = (ke/2)-W₁
Given: e = (40-20) = 20 cm = 0.1 m
Substitute these value into equation 1
W₂ = (k×0.2²/2)-0.005
W₂ = 0.015k Joules.
W₂/W₁ = 0.015k/0.005k
W₂/W₁ = 3
Therefore,
W₂ = 3W₁
Answer:
the next number would be -21
