Keeping in mind that, there are 5280 feet in 1 mile, and 60 minutes in an hour and 60 seconds in each minute, thus 60*60 seconds in an hour, or 3600 seconds.
Ok, I'm only in 8th grade but I believe you do addition first in the problem. Hope this helps! <3
Answer:
(x-1)² = 3
Step-by-step explanation:
Given f(x)=x²−2x−2
Completing x²−2x−2 = 0 to square
- x²−2x − 2=0
- x²−2x + 1 - 3 =0
- (x - 1)² - 3 = 0
- (x - 1)² = 3
Correct choice is D
Answer:
Ok:
Step-by-step explanation:
So f°g . means f(g(x)). (The ° should be more center and bigger but I don't know to do that on a keyboard). f(g(x)) means that you replace the x in f(x) with the g(x) function. i.e:
if f(x) = 2x+2
and g(x) = 
f(g(x)) =
.
Similarly, in this case, we get f(x) = 2x-3 and g(x) = 3x-2.
Then, f(g(x)) or f°g(x) is 2(3x-2) - 3.
And we plug in -2 to solve:
2(3(-2)-2)-3.
and get -19.
Check if I am wrong because everyone makes mistakes but that is the way to solve this.
Answer:
8.06 ft or
ft
Step-by-step explanation:
Since Rebecca bought a square table and squares have equal sides, you can take the square root of the area of the table, which gives you
ft per side. This can be approximated to 8.06 ft.
