y = 13.8
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
going off of 60 it be 66, 72, then 78. meaning 6 is a multiple of 78.
Answer:
E and F= 54 Degrees D is 90 degrees
Step-by-step explanation:
Answer:
-13
Step-by-step explanation:
<u>See steps below:</u>
- 2(3x+6)=3(x-9) ⇒ distribution
- 6x + 12 = 3x - 27 ⇒ grouping like terms
- 6x - 3x = -27 - 12 ⇒ simplifying
- 3x = -39
- x= -39/3
- x = -13 ⇒ answer
Answer:
Option A is correct
Step-by-step explanation:
The given equation is
h = -16t^2+6t+4
When the ball will hit the ground, height h = 0
Putting value of h = 0
0 = -16t^2+6t+4
Now solving to find the value of t
=> -16t^2+6t+4 = 0
Multiply with -1
16t^2-6t-4=0
Using quadratic formula to find value of t
a= 16, b= -6 and c= -4
Putting values,
Since time cannot be negative, so t = 0.721 or 0.72
So, Option A is correct
