The true answer is A. all parallelograms are rectangles
(350-126)/(5-3)=112m/s
This is the average speed in the time from 3 to 5 seconds...
dd/dt 98,126,154
d2d/dt2 28,28
She actually had a constant acceleration over the entire time period.
The function for that table is:
d(t)=14t^2
Her actual velocity at any point is v(t)=28t (you can see that if you take the mid point of the interval, 4s, you will get the average velocity found earlier)
A+B: the matrix with same dimension a A and B, the element in row i and column j is: Aij+Bij
Same for A-B, but with Aij-Bij
Step-by-step explanation:
Hello there!
Solve for x:
-3x(x-8)-7x=12
-3x^2+24x-7x=12
-3x^2+17x+12=0
Can you factor it further?Feel free to ask questions in the comments.
