Simply subtract 10,000 from 235,497. You will get 225,497.
Usually t is used for time. Plug in the correct value for t. Which is 5 hours.
w = -500(5) + 7000 ; Start
w = -2500 + 7000 ; Multiple -500 by 5
w = 4500 ; Subtract 2500 from 7000
So, after 5 hours of draining the pool, 4500 liters (I choose liters. It didn't specify in the question) of water are still in the pool.
Answer:
see below
Step-by-step explanation:
The applicable rules of exponents are ...
- (a^b)(a^c) = a^(b+c)
- a^(-b) = 1/a^b
Using these to simplify your expression, you get ...
Answer: He owes Beth and his mom $125
Step-by-step explanation:
Hi there!
α, β, γ are the zeroes of the polynomial x³ + px² + qx + 2
Then,
• α + β + γ = - p ---(i)
• αβ + βγ + γα = q. ---(ii)
• αβγ = - 2. ---(iii)
We're Given :-
αβ + 1 = 0 Or αβ = - 1
Substitute " αβ = - 1 " in eqn. (iii) :-
(- 1) γ = - 2
γ =
γ = 2
Now. Accr'ding to the question :-
2p + q + 5 = - 2 (α + β + γ) + (αβ + βγ + γα) + 5
= - 2 (α + β + γ) + (αβ + [ γ (β + α) ] + 5
= - 2 (α + β + 2) + [ - 1 + 2 ( α + β ) ] + 5
= - 2α - 2β - 4 - 1 + 2α + 2β + 5
= 5 - 5
= 0
∴ 2p + q + 5 = 0
~ Hope it helps!
