Answer:
24 males
7 females
Step-by-step explanation:
<u>Step 1: Write the data</u>
Total number of students: 31
Number of males: x
Number of females: x - 17
<u>Step 2: Form an equation</u>
males + females = total students
x + x - 17 = 31
2x = 48
x = 24
There were 24 males
<u>Step 3: Find the number of females</u>
Number of females = x - 17
Number of females = 24 - 17
Number of females = 7
Therefore, there were 24 males and 7 females in the class.

Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
