You can use SAS since you know one pair of sides are congruent and AC splits them so those must make those sides equal. And since those sides, DC and BC, are congruent, the angles must be as well. You can use numbers to prove the angles of D and B or just use that when 2 sides and an angle are congruent, the 3rd side must be congruent.
Answer:
False
Step-by-step explanation:
6.08x10^-12
This means that we move the decimal to the left 12 times. Which is .00000000000608
Answer:
Part A) v(t) = u + a t m/sec
Part B) s(t) = s₀ + ut + 0.5 at² meters
Step-by-step explanation:
Given: An object has velocity u m/s at time 0 and constant acceleration a.
<u>Part A) find the velocity after t seconds.</u>
We should know that:
By integrating both sides with respect to the time t
∴∫ dv = ∫ a dt
∴ v(t) = a t + constant
the object has velocity u m/s at time 0 ⇒ constant = u
<u>∴ v(t) = u + a t </u> m/sec
<u>Part B) find the displacement of the object between time 0 and time t.</u>
We should know that:
By integrating both sides with respect to the time t
∴∫ ds = ∫ v dt
∵ v(t) = u + a t
∴ ∫ ds = ∫ (u + a t) dt
∴ s(t) = ut + 0.5 at² + constant
Let at t = 0 displacement = s₀ ⇒ ∴ Constant = s₀
<u>∴ s(t) = s₀ + ut + 0.5 at²</u> meters
