e. 7. 0 × 10^-1
<h3>What is scientific notation?</h3>
Scientific notation is simply a way of expressing numbers that are too large or small to be written in decimal form.
It may be referred to as standard index form or scientific form.
From the information given, we have;
a. 0. 000003 is written in standard form as;
= 3 × 10^-6 × 3 × 10^6
= 3 × 10^-6 + 3
= 3 × 10^0
= 3
b. 56, 000, 000. 00 is written in standard form as;
= 5. 6 × 10^7 × 6 × 10^-7
= 33. 6 × 10^7 -7
= 33. 6 × 10^0
= 33. 6
c. 8. 0 × 10^-3 × 7. 2 × 10^5
= 57. 6 × 10^-3 + 5
= 57. 6 × 10^2
d. 4. 0 × 10^-3 × 4. 0 × 10^-4
= 4. 0 ^ -3 +(-4)
= 4. 0 × 10^-7
e. 7. 0 × 10^3 × 7. 0 × 10^4
= 7. 0 × 10^ 3-4
= 7. 0 × 10^-1
Thus, scientific notation is also referred to as standard form.

Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is:
![M=(\frac{x_1+x_1}{2},\frac{y_1+y_2}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7Bx_1%2Bx_1%7D%7B2%7D%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%29)
Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:
![M=(\frac{5+9}{2},\frac{6+2}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B5%2B9%7D%7B2%7D%2C%5Cfrac%7B6%2B2%7D%7B2%7D%29)
Add:
![M=(\frac{14}{2},\frac{8}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B14%7D%7B2%7D%2C%5Cfrac%7B8%7D%7B2%7D%29)
Divide by 2:
![M=(7,4)](https://tex.z-dn.net/?f=M%3D%287%2C4%29)
So, our midpoint is (7,4).
And we're done!
Time = distance / speed
Samma : 200/25.98 = 7.70 meters per second
Tom : 100 / 12.54 = 7.97 meters per second
so the faster runner is Tom
Answer:
answer 1962323
Step-by-step explanation:
The missing fraction would be
![\frac{4}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B6%7D%20)
since it is exactly in the halfway between
