Answer:
Step-by-step explanation:
12 ÷ 12 ÷ 4 × 3^2
Exponential is treated first
= 12 ÷ 12 ÷ 4 × 9
Division follows
= 1 ÷ 4 × 9
= 1/4 × 9
= 9/4
= 2 1/4
P= 2500
r= 0.0465
A= P. e^(rt)
Where:
A = final mount
P = principal investment
r= rate
T= time (years)
To double it:
2 x 2500 = 2500 e^(0.0465 x t)
(2 x2500)/2500= e^(0.0465 x t)
2= e^(0.0465 x t)
Ln 2 = Ln e^(0.0465 x t)
Ln2 =0.0465t (Ln e)
Ln2 = 0.0465 t
t = Ln2 /0.0465
t= 14.91 years
Triple:
3 x2500 = 2500 e^(0.0465 t)
(3 x 2500 ) /2500 = e^(0.0465 t)
3 = e^(0.0465 t)
ln3 = ln e^(0.0465 t)
ln3 = 0.0465t Lne
ln3= 0.0465t
ln3/0.0465 =t
t= 23.63 y
Answer:
Infinite amount of solutions
Step-by-step explanation:
Parallel lines have no solution
Same lines have infinite solutions
Intersecting lines have 1 solution
Step 1: Write out equation
-14(x - 5) = -14x + 70
Step 2: Distribute -14
-14x + 70 = -14x + 70
Here we see that we have 2 exact same lines. Therefore, we have infinite amount of solutions.
Alternatively, we can plug in any number <em>x </em>and it would work. So then we would have infinite amount of solutions as well.
Equation:
Since there aren't any like terms and it can't be factored, your answer would be:
