Answer:
=1.23*10^6
Step-by-step explanation:
We have to calculate
(1.93*10^7 )-(9.7*10^6)
In order to add or subtract two numbers in scientific notation, we have to make sure that the power of exponents in both numbers is same.
We have to reduce the power of 10 in first number from 7 to 6
So,
Step 1:
1.93*10^7=1.93*10*10^6
=10.93*10^6
Now,
Step 2:
=(1.93*10^7 )-(9.7*10^6 )
= 10.93*10^6- 9.7*10^6
Step 3:
=(10.93-9.7)*10^6
=1.23*10^6
Answer:
= x² + 7x + 70
Step-by-step explanation:
-7x - 60 = x² + 10
= -x² - 7x - 60 - 10
= -x² - 7x - 70
= x² + 7x + 70
Answer: 2 the first one
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
(x)^2+(1/x)^2=18
(x-1/x)^2+2x.1/x=18
(x-1/x)^2+2=18
(x-1/x)^2=16
(x-1/x)^2=4^2
x-1/x=4
Answer:
4
Step-by-step explanation:
Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?
To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.
Here it is 4.
