Answer:
7*10*10*10 = 7000
7*10 = 70
70*10 = 700
700*10 = 7000
Step-by-step explanation:
The given expression is:
7*10^3
Here 10^3 means that 10 will be multiplied 3 times:
7*10*10*10 = 7000
How did we get 7000?
7*10*10*10 = 7000
7*10 = 70
70*10 = 700
700*10 = 7000
We can also say that there are 7 1000s in 7000....
Answer: Hi! the notation 7×10^3 means 7*10*10*10, where 3 is the exponent.
You can think this notation as how many zeros you can add to the left (or right if the exponent is negative) of a number.
so 7×10^3 has an exponent equal to 3, so you add 3 zeros and get : 7000.
if we do the multiplication, 7*10*10*10 = (7*10)*10*10 = 70*10*10 = (70*10)*10 = 700*10 = 7000.

Answer:
Step-by-step explanation:
The volume for a sphere is
. Our radius is 21 inches, so
and
. Multiplying straight across the top, using the fact that 3.14 is pi:
and divide to get that
V = 38772.72 in^3
Steps given by
- Find corresponding y values when x = 2, x = 1, and x = 0. Then plot the points to finish the line.
- The initial value corresponds to the y value when x=0
- Find the rate of change using rise over run
