= -y^3 + 4y^2 - 7y^3
= -8y^3 + 4y^2
answer
-8y^3 + 4y^2
Answer:
7.41
Step-by-step explanation:
Vertical component:
S = 268.8
U = 0
V =?
A = 9.8
T=?
S = ut + 0.5at^2. u = 0
268.8 = 0.5x9. 8xt^2
T = 7.41 seconds
I think a. But I don’t understand this question.
Y=mx + b
10x.5y.10=30
10x.5y=30-10
10x.5y=20
5y= -10x + 20
5/5 = -10/5(x) + 20/5
Y= -2x +4
Answer:
6/5, or 1 1/5
Step-by-step explanation:
I use a method called KCF, which means Keep Change Flip. Here is your current expression: 2/5 / 1/3. First, keep the first fraction. Next, change the sign into a multiplication symbol. Now, you have 2/5 x 1/3. Finally, flip the last fraction into 3/1. Now, this is your expression: 2/5 x 3/1. Multiply numerator by numerator, denominator by denominator. Your final answer is 6/5, or 1 1/5 simplified.
