Answer:
7x^2 + 7
Step-by-step explanation:
So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.
Hope that explanation makes sense
Answer:
<u>2.5 seconds</u>
Step-by-step explanation:
Resting position is at y = zero which mean x intercept
So, we need to find the time between two consecutive points of intersection with the x-axis.
Which mean it is the half period of the given function as it is a sine wave
From the graph we can deduce that
<u>2.5 seconds</u> are required for the pendulum to move from its resting position, swing in one direction and return to its resting position.
Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)
456=40w+4w^2+100w
456=4w^2+140w
114=w^2+35w
0=w^2+35w-114
find what 2 numbers multiply to get 114 and add to get 35 and factor
-3 and 38
0=(w-3)(w+38)
set each to zero
w-3=0
w=3
Answer:
I think you would divide all of your numbers.
Step-by-step explanation:
381 1/10- 214 43/100= 166.67 hope that helps
