Answer:
1 mile per hour
Step-by-step explanation:
you just double it
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
Answer:
0.86
Step-by-step explanation:
just look at the second and third number to see if it can round or not
Answer:
x=5/8
Step-by-step explanation:
11x-6=3x-1
-3x -3x
8x-6=-1
+6 +6
8x=5
8/8 5/8
x=5/8
