Answer:
There are 11 numbers divisible by 9 between 1 and 100, and 25 numbers divisible by 4 between 1 and 100.
Step-by-step explanation:
So there are 11 + 25 = 36, so 36 numbers divisible by one or the other, but this also includes every number which is divisible by both 9 and 4 twice.
So, for example, 36 and 72 is counted once as a number divisible by 9, and then again as a number divisible by 4. Count of such number which are counted twice 2
So answer is 11+25-2 =34
Answer:
THE VALUE OF X IS 18
Step-by-step explanation:
Answer:
x ∈ (-∞,-3)∪(0.5,∞)
Step-by-step explanation:
2x^2+6x-x-3>0
2x(x+3)-1(x+3)>0
(2x-1)(x+3)>0
x ∈ (-∞,-3)∪(0.5,∞)

Answer:
a. 1.48 seconds
Step-by-step explanation:
You want to find the larger value of t such that h(t) = 10.
-16t^2 +25t +8 = 10
16t^2 -25t +2 = 0 . . . . subtract the left side to get standard form
Using the quadratic formula, we find the values of t to be ...
t = (-(-25) ± √((-25)^2 -4(16)(2)))/(2(16)) = (25±√497)/32
t ≈ 0.08 or 1.48
The ball goes in the hoop about 1.48 seconds after it is thrown.

<em>Additional comment</em>
The quadratic formula tells us the solution to ...
ax² +bx +c = 0
is given by ...

Here, we have a=16, b=-25, c=2. Of course, our variable is t, not x, but the relation is the same.
