You multiply by 10 or more
8o+12y=362
12o+8y=388
Im choosing “o” for orchid and “y” for lily
20o+20y=750
20o=750–20y
o=37.5–y
(37.5–y)+20y=750
-y+20y=712.5
19y=712.5
y=37.5
So, lilies sell for $37.50
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
Evaluate each expression individually and then combine like terms:
5 log₄(x²) = 5 = 5 = 5 = 5 log₂x = log₂x⁵
4 log₂(x) = log₂(x)⁴ = log₂(x⁴)
**********************************************
log₂(2x + 1) - 5 log₄(x²) + 4 log₂(x)
= log₂(2x + 1) - log₂x⁵ + log₂(x⁴)
= log₂[(2x + 1)*(x⁴) ÷ x⁵]
= log₂
= log₂
