Answer:
4 seconds.
Step-by-step explanation:
The function f(x)=-10(x)(x-4) ........ (1), represents the approximate height of a projectile launch on the ground into the air as a function of time in seconds x.
Now, we are asked that for how long from the launch does the projectile stays in the air.
Therefore, we have to solve the equation (1) making f(x) as zero.
Hence, 10x(x - 4) = 0
⇒ x = 0 or x = 4
(As x can not be zero since at x = 0 sec, the projectile was at the ground.}
Hence, x = 4 seconds.
Therefore, the projectile was in the air for 4 seconds. (Answer)
Answer:
is the equal sign supposed to be there? if it wasnt then answer would be 42x^6y^11
Step-by-step explanation:
Well I don't know how to show work on this one.
50. 2 3/4 is between 2 and 3, three times farther from two than three. Draw a dot in approximately that locations and mark it 2 3/4.
51. 4 1/3 is between 4 and 5, twice as far from five as from four. Draw a dot and mark it 4 1/3.
Answer:
4,000 enroll
Step-by-step explanation:
If 20,000 students apply and the university only accepts 40%, the university accepted 8,000 students.
How many actually enrolled?
Of those accepted students (8,000), 50% enroll.
8,000 / 2 OR 8,000 x 0.50 = 4,000 students actually enroll.
Ok so we know that each combo meal is $5. So 24 x 5 = $120
$6 service charge has to be divided by 120.
6/120 = 0.05
5%
