Simplify the following:
(25/a - a l)/(a + 5)
Put each term in 25/a - a l over the common denominator a: 25/a - a l = 25/a - (a^2 l)/a:
(25/a - (a^2 l)/a)/(a + 5)
25/a - (a^2 l)/a = (25 - a^2 l)/a:
Answer: ((25 - a^2 l)/a)/(a + 5)
This problem can be solved directly by neglecting the
initial velocity given. All we have to do is to plug in t = 4 in the given
equation. That is:
h = -16^2 + 123 * 4
h = 236 ft
Answer:
26
Step-by-step explanation:
Subtract the mean (84) from each of the four scores, obtaining
2, -3, 3, - 2
These are the "deviations."
Next, square each of these four deviations, obtaining
(2)^2 = 4, and:
(-3)^2 = 9, and:
(3)^2 = 9, and:
(-2)^2 = 4
Then the sum of the squared deviations of the scores from the mean is 26.
I drew it on paper and I got B as the pages that will face each other.
Answer: B. 22 and 23
Answer:80 meters
Step-by-step explanation: 24 meters = 36 secs
2 mins = 120 secs
Cross multiply
24×120/36
= 80 meters
