Q must be positive in F.
F. r squared will be positive, because any number times itself is positive, and to get a positive number for the answer, the two numbers you multiply need to be the same sign. If r squared is positive, q must be too.
G. q does not have to be positive. If r is a negative number, then q can be negative. Say q=-2 and r=-3. -2-(-3) changes to -2+3, which equals 1.
H. Again, q can be negative if r is negative (two negative numbers multiplied together equals a positive answer.
J. q can be negative because even a negative number turns positive when squared.
Hope this helped you. :)
How many times do 15 minutes fit into one hour? 4 times: 4*15=60 mins.
So that means that 4 times per hour 10 flights appear, and in total 4*10=40 planes arrive over one hour!
Yes, because 10 x 10 x 10 x 10 x 10 (which equals 10^5) is equal to 100,000.
Remember, 10 to the power of anything (like 8, 5, or 9) just means that you have to count out however many zeros the exponent tells you to, which in this case, is five.
Angles 4,2,6,and 8 are all 106 degrees. To find the other number, subtract 106 from 180 and that is the rest of the numbers. All you have to do is write the measure (m) of the angle listed.
180-106=74 So,
1) 74 degrees
2)106 degrees
3)74 degrees
4) 106 degrees
5)74 degrees
6)74 degrees
