Step-by-step explanation:
(5y+6)^2=24
i.e, 25y^2+60y+36=24
i.e, 25y^2+60y+12=0
i.e, using rule of quadratic equns
y= {-60±√3600-(4×25×12)}/2×25
i.e,y= (-60±√2400)/50
i.e,y= -1.2 ± 0.4√6

Answer:
1. 42.95
2. 8.8 meters; -14 meters
3. -53; 780
Step-by-step explanation:
1. subtract 1985 from 2013, you get 28
plug in 28 to the equation and you get 42.95
2. plug in the values of t
-4.9 (2^2) + 1.7 (2) + 25 = 8.8
-4.9 (3^2) + 1.7 (3) + 25 = -14
3. plug in your values again
5^3 - 6 (5^2) - 8 (5) + 12 = -53
12^3 - 6 (12^2) - 8 (12) + 12 = 780
Answer:
E
Step-by-step explanation:
In the picture attached, the Truth Table for the operator “OR” is shown. With it we can compute the next table:
p q ∧ r p ∨ (q ∧ r)
T T T
T F T
F T T
F F F
We want that p would be false and p ∨ (q ∧ r) would be true, which corresponds to the third row of the previous table.
The only row from the table of the question that satisfies this criterion is row E.
Answer:
2
Step-by-step explanation:
A state has 2 senators, so once you choose the state, there are 2 ways you can choose a senator from that state.
Answer:
1285.37
Step-by-step explanation: You can use the formula for compound interest:
P(1+R)^t
P = the principle, the amount of money
(1+R) = the rate, (%) as a decimal plus 1
^t = to the power of the number of years
Substitute the values:
750(1+0.08)^7
750(1.08)^7
1285.37
