Answer:
3.84 * 10^8 meters
Step-by-step explanation:
As the speed of light is 300,000,000 meters/second and the time that the light takes to go from the moon to the Earth is 1.28 seconds, we can find the distance using the formula:
Distance = speed * time
So we have that:
Distance = 300,000,000 * 1.28 = 384,000,000 meters
In cientific notation, we need the first number to be in the interval from 1 to 10, so we have 3.84, and we have to multiply by 10^8 to reach our result, so we have:
Distance = 3.84 * 10^8 meters
The value of the fractions will be:
1. 8 13/20
2. 2 4/5
3. 5/6
<h3>How to explain the fraction?</h3>
1. 6 1/4 + 2 2/5
LCM of 20
6 1/4 + 2 2/5.
6 5/20 + 2 8/20
= 8 13/20
2. 1 1/5 × 2 1/3
= 6/5 × 7/3
= 42/15
= 14/5
= 2 4/5
3. 3 1/3 - 2 1/2
= 3 2/6 - 2 3/6.
= 5/6

Answer:
<u>A. Quadratic, degree 2</u>
Step-by-step explanation:
The degree is found by simply finding the term with the power of, that is the highest. Which would be 2x^2. It is raised to the 2nd power, so the degree is 2.
Y = mx + c
m = 2
y = 2x + c
At (5, 0)
0 = 2(5) + c
c = -10
y = 2x - 10
