Answer:
8.66666666666 (11)
Step-by-step explanation:
2 divided by 3 -.666666666666666
4 times 3 is 8
Answer:
7
Step-by-step explanation:
The x-intercept is the x-value when y=0, so we plug in y=0,
x=-2(0)+7
x=0+7
x=7
So the x-intercept is 7
Answer:
(x + 5) - 9
Step-by-step explanation:
An expression is a mathematical phrase that contains a variable and a constant, but not an equal sign. Using key words from the given verbal expression, we can make an algebraic expresion:
'nine less than' = subtract 9 or - 9
'the sum of x and 5' = addition of 'x' and '5' or x + 5
put them together: (x + 5) - 9
I think its true im not sure tho
hope it helps
Answer:
502.4 ± 30.14 in^3
Step-by-step explanation:
r = 4 in, h = 10 in
error = ± 0.1 inch
Volume of a cylinder, V = π r² h
Take log on both the sides
log V = log π + 2 log r + log h
Differentiate both sides
dV/V = 0 + 2 dr/r + dh /h
dV/V = 2 (± 0.1) / 4 + (± 0.1) / 10
dV/V = ± 0.05 ± 0.01 = ± 0.06 .... (1)
Now, V = 3.14 x 4 x 4 x 10 = 502.4 in^3
Put in equation (1)
dV = ± 0.06 x 502.4 = ± 30.144
So, V ± dV = 502.4 ± 30.14 in^3
