Answer:
yes to both
Step-by-step explanation:
(1) For y=1, and x=a, ...
a² + 1² ≤ 3
-√2 ≤ a ≤ √2 . . . . . subtract 1 and take the square root
All values of "a" are less than 2 inside the circle.
__
(2) For y=4 and x=a, ...
2·4 +4·a = 10
4a = 2 . . . . . . . subtract 8
a = 1/2 . . . . . . .divide by 4
The value of "a" for point (a, 4) on the line is less than 2.
Answer:
6840
Step-by-step explanation:
Well we know there's 24 hours in a day so dividing that by 1440 we get 60. Now we know that it consumes 60 watts ever hour. so now we just have to figure out how many hours there are and times that by 60. So there are 96 hours in 4 days plus 28=114. So times that by 60 ( watts) 114×60=6840
So that's your awnser.
Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!

To solve this, you need to have a common denominator for both terms. In order to get the equivalent fraction with the common denominator, you multiply each fraction by a version of 1. Here, it seems like our least common denominator (or LCD) is 12. Therefore, you multiply 1/4 by 3/3 and you multipy 2/3 by 4/4 to get 3/12 plus 8/12 = 11/12.

Answer:
Dan obviously didn't measure the remainder, which is (C) 3 11/12 ft.
Step-by-step explanation:
After the cut, Dan has ...
8 3/4 - 4 5/6 = 8 9/12 - 4 10/12
= (8 -4) +(9/12 -10/12) = 4 -1/12 = 3 11/12 . . . ft
