B, the bottom of the figure contains points E, F, and H
Hello,
g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32
h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0
==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s
25=-16*1.25²+v*1.25
==>v=50/1.25=40
Equation h=-16t²+40*t
Answer:
Step-by-step explanation:
275 (slushy) in a cup.
After 13 seconds, 210 milliliters of slushy remained.
divide the original by the seconds then the answer by the left over. And then you get your answer.
hope it helps!
please give me brainliest
Answer:
The fourth term of the expansion is -220 * x^9 * y^3
Step-by-step explanation:
Question:
Find the fourth term in (x-y)^12
Solution:
Notation: "n choose k", or combination of k objects from n objects,
C(n,k) = n! / ( k! (n-k)! )
For example, C(12,4) = 12! / (4! 8!) = 495
Using the binomial expansion formula
(a+b)^n
= C(n,0)a^n + C(n,1)a^(n-1)b + C(n,2)a^(n-2)b^2 + C(n,3)a^(n-3)b^3 + C(n,4)a^(n-4)b^4 +....+C(n,n)b^n
For (x-y)^12, n=12, k=3, a=x, b=-y, and the fourth term is
C(n,3)a^(n-3)b^3
=C(12,3) * x^(12-3) * (-y)^(3)
= 220*x^9*(-y)^3
= -220 * x^9 * y^3
Answer:
and 
Step-by-step explanation:
We are given the term 
.
<em>It is known that, 'A monomial is an algebraic expression consisting of one term'.</em>
So, we add the given options to .
1. 
2. 
3. 
4. 
5. 
6. 
7. 
As, we can see that only option 2 and 6 results in an expression having one term.
Thus, adding and to results in a monomial.
