99,999,999 + (-4) is basically 99,999,999 - 4
99,999,999 - 4 = 99,999,995
Answer:
see explanation
Step-by-step explanation:
Using the rules of exponents
All the exponents inside the parenthesis are multiplied by the exponent outside the parenthesis.
Then
÷
[ Using the rule = ]
= ÷
= ÷
=
=
= n²
= n² = , so x = 4 and y = 2
Then
= = = = 1 ← as required
Answer:
6.2y - 3.7
Step-by-step explanation:
−y+5.3+7.2y−9
Subtract 9 from 5.3 to get −3.7.
−y−3.7+7.2y
Combine −y and 7.2y to get 6.2y.
6.2y−3.7
Answer:
The third graph is the graph of the given function
Step-by-step explanation:
A simple technique that can be used to identify the graph that matches the given function is; determination of the x and y-intercepts. In this case, determining the y-intercept and then using elimination will suffice in matching the function with its graph. At the y-intercept the value of x is always zero, so we replace x with zero in the right hand side of the equation; y(x) = 2^(0+3) = 8. The graph of the function should therefore cross the y-axis at the point (0,8). The third graph is the graph of the given function.
Answer:
C. 43.96
Step-by-step explanation:
The circumference is C=2(3.14)R.
So first you would want to substitute 7 in for the R. The equation would than look like C=2(3.14)(7) This would equal 43.96 m.
