Answer:
B △QMR≅△TMS by ASA
Step-by-step explanation: Could be wrong idk.
F(x)=5-3x³
f'(x)=-9x²
f'(3)=-81
y+76= -81(x-3)
y+76=-81x+243
y=-81x+167
Given that the rate of Uranium decay is 57%, this means that after each day, only 0.43 of the mass from the prior day is left. The equation that would best represent the scenario is,
a(t) = a₁(0.43^t)
where a(t) is the mass after t days and t is the number of days. Substituting,
a(t) = 3,280(0.43^15)
= 0.01 lbs.
Answer:
B. Brand A $0.21
Step-by-step explanation:
(round to nearest cent)
Brand A: 21.99/105 = .2094 = .21 ( .2094 rounds to .21)
Brand B: 17.99/80 = .2248 = .22 ( .2248 rounds to .22)
Therefore Brand A is a better buy for $0.21 per load
Answer:
x = 2
Step-by-step explanation:
3(5x - 2) + 1 = 25 (Given)
3(5x) + 3(-2) + 1 = 25 (Distributive Property of Equality)
15x + -6 + 1 = 25 (Simplify)
15x - 5 = 25 (Simplify)
15x + 5 + 5 = 25 + 5 (Addition Property of Equality)
15x = 30 (Simplify)
(Division Property of Equality)
x = 2 (Simplify)
