Given the equation :
We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :
Answer: Yes, it is a real number. 3.4 is a rational number and rational numbers are real numbers. So 3.4 is a real number.
Answer:
f(x)=x^3+7
y=x^3+7
x=y^3+7
y^3=x-7
y=cube root (x-7)
f(x) inverse=cube root of x-7

I have no idea
Step-by-step explanation:
I have no idea
For this, we use the given info plus a bit of multiplying and subtraction
part 1)
we know that she's 25 y/m
so 5 minutes simply means 25 × 5
now we simply subtract this from 1000 (the original distance)
part 2)
the total time taken is even easier to find
all we have to do is divide 1000 by 25
