Answer:
no
when you enter the point into the equation and solve, it does not work
15 books, because it asked for DIFFERENT books not the same. Just take the same book away from each individual child and add the rest and it equals 15.
Answer:
3) 174°15'18"
4) 34.859722...(repeating)°
5) 434°, -286°
Step-by-step explanation:
There are 60 minutes in a degree, and 60 seconds in a minute.
3) To find minutes, multiply fractional degrees by 60:
.255° = 0.255°×(60'/1°) = 15.3'
To find seconds, multiply fractional minutes by 60:
0.3' = 0.3'×(60"/1') = 18"
Then the whole angle is ...
174.255° = 174° 15' 18"
__
4) The conversion works the other way, too.
34° 51' 35" = 34° +51(1/60)° +35(1/3600)° = (34 619/720)°
= 34.8597222...° (a repeating decimal)
__
5) Add or subtract multiples of 360° to get co-terminal angles.
74° +360° = 434°
74° -360° = -286°
I'm pretty sure that this is how it goes
If ƒ(x ) = x^2 + 1, find ƒ(a + 1).
x=(a+1) so u replace x to get this:
f(a+1) = (a+1)^2+1
If you square "a" it just becomes a^2 and "1" squared is just "1"
1+1=2
Answer: a^2+2a+2
