One way of calculating the volume would be to convert all of these measurements to decimal:
V = (18 in)(30 in)(8 in) = 4320 cubic in
Answer:
s = 
Step-by-step explanation:
Given
v² = u² + 2as ( subtract u² from both sides )
v² - u² = 2as ( divide both sides by 2a )
= s
Given
v² = u² + 2as ( subtract 2as from both sides )
v² - 2as = u² ( take the square root of both sides )
± 
= u
Answer:
PS = 7
k = 9
Step-by-step explanation:
RS = PQ Given
3x - 7 = x - 1 Substitute algebraic terms. Subtract x from both sides
3x-x - 7 = x - 1 - x Combine
2x - 7 = - 1 Add 7 to both sides.
2x - 7+7 = -1+7 Combine
2x = 6 Divide by 2
2x/2 = 6/2
x = 3
Length of PS = x - 1 + x + 3x - 7
Length of PS = 5x - 8
Length of PS = 5*3 - 8
Length of PS = 7
=========================
f(x) = k - x^2
x = 2
f(x) = 5 is the given point
5 = k - x^2 Substitute for x^2
5 = k - 2^2 Expand
5 = k - 4 Add 4 to both sides.
5+4=k-4+4 Combine
k = 9
