Answer:
15
Step-by-step explanation:
Put the given value of x where x is in the expression and do the arithmetic.
4^3 -(3 +4)^2 = 64 -49 = 15
The value of the expression for x=4 is 15.
I think the answer is 10/7 or 3.82
Answer:
x=18
Step-by-step explanation:
x2+4=40
-4 -4
x2=36
/2 /2
x=18
The absolute error is 4 cu. in. and the relative error is 10%.
To find the absolute error, subtract the actual value from the estimate:
36 - 40 = -4
With absolute error, we ignore negative signs, so the absolute error is 4 cu. in.
To find the relative/percent error, divide the absolute error by the actual value:
4/40 = 0.1
Converting this to a percent, 0.1(100) = 10%
