Vitek1552 [10]

Answer:

3.5 to 20.5 hours

Step-by-step explanation:

The range of the sine function is -1 to 1, so the range of H will be ...

-8.5 +12 = 3.5

8.5 +12 = 20.5

The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.

Which point lies on the circle represented by the equation (x−1)2+(y−3)2=72? f (8, 3) g (-1, 4) h (1, 3) j (0, 7)?

Andrews [41]

For this case, the equation of the circle is given by:
$(x-1) ^ 2 + (y-3) ^ 2 = 7 ^ 2
$
We evaluate the points to see which ones satisfy the equation.
We have then:
For (8, 3):
$(8-1) ^ 2 + (3-3) ^ 2 = 7 ^ 2
$
Rewriting we have:
$(7) ^ 2 + (0) ^ 2 = 7 ^ 2

 7 ^ 2 = 7 ^ 2$
We observe that this point satisfies the equation and therefore, is in the circle.
Answer:
A point lies on the circle represented by the equation $(x-1) ^ 2 + (y-3) ^ 2 = 7 ^ 2$ is:
f (8, 3)

Which number is not in scientific notation?

Gre4nikov [31]

Answer: D

Step-by-step explanation:

Scientific notation means that the first number is like:
