Answer:
51
Step-by-step explanation:
51.8-0.8=51
Answer:
You would divide 4,200 by 12=350
Step-by-step explanation:
A.) b = 0.7a
d) 1a = b
These two equation shows the direct variation. with the coefficient of a as the constant of variation.
y = kx ; where k is the constant of variation. y directly varies with x at the rate of k.
b = 0.7a where b represents y ; a represents x; and 0.7 represents k.
1a = b where b represents y ; a represents x ; and 1 represents k.
The answer is A true it’s is three times the volume
Answer:
A: a(t)
B: v(t)
C: s(t)
Step-by-step explanation:
One graph is position, s(t).
Another is velocity, v(t) = ds/dt (slope of the tangent line of the position curve).
The third is acceleration, a(t) = dv/dt (slope of the tangent line of the velocity curve).
If graph A is s(t), then velocity v(t) would always be positive. No graph fits, so A is not s(t).
If graph B is s(t), then velocity v(t) would start negative then become positive, like graph A does. If graph A is v(t), then acceleration a(t) would always be positive. No graph fits, so A is not v(t), which means B is not s(t).
If graph C is s(t), then velocity v(t) would always be negative, like graph B. If graph B is v(t), then acceleration a(t) starts negative then becomes positive, like graph A does.
Therefore:
A: a(t)
B: v(t)
C: s(t)
