Answer:
84
Step-by-step explanation:
Using the definition
n ! = n(n - 1)(n - 2).... × 3 × 2 × 1
Then = 9/6 3 = 987654321/654321321
Cancel 6(5)(4)(3)(2)(1) on numerator/ denominator, leaving
= 987/321
=504/6
= 84 → B
Correct expression is 
. As n is greater then or equal to so circle will be closed . Correct options are B) and D)The circle is closed.
<u>Step-by-step explanation:</u>
Here we have , Solve Negative two-thirds n less-than-or-equal-to 16. We need to find Which of the following must be true about the inequality and the resulting graph . Let's find out:
We have expression as : 
⇒
⇒ 
⇒ 
⇒ 
⇒ 
⇒
Therefore , Correct expression is . As n is greater then or equal to so circle will be closed . Correct options are B) and D)The circle is closed.
Answer:
540
Step-by-step explanation:
Y - intercept is the value of y - coordinates of the point where the line intersects the y - axis, that is :
Y - intercept = 0
V o = 18 m/s,
v o y = v o * sin 35° = 18 * 0.5736 = 10.32437 m/s
y = v o y· t - 1/2 g t²
0 m = 10.32437 m/s t - 1/2 · 9.81 m/s² · t² /: t
4.905 t = 10.32437
t = 10.32437 : 4.905
t = 2.1 s
