AEC and BED are vertical angles, which mean they are equal.

Set those two equations to equal and find those angles, then we can find AEB.


First:

3y+20 = 5y -16

Add 16 to each side:

3y+36 = 5y

Subtract 3y from each side:

36 = 2y

Divide both sides by 2: y = 36 /2

y = 18.

Now solve AEC:

3(18) +20 = 54+20 = 74


Both AEC and BED are 74 degrees.

AEB and CED asre also vertical angles and would be the same.

Subtract 74 +74 from 360 then divide by 2:


AEB = (360 - 74 - 74) / 2

AEB = 212 /2

AEB = 106 degrees

You buy Apple stock for $120 per share over a period of time the stock value increased at a weekly rate of 5% you sell the stock
Rainbow [258]

Answer:

8.31  weeks

Step-by-step explanation:

Given that the cost of one share of Apple stock, C=$120

Rate is the increment of the stock value, R= 5%/week=0.05 / week.

Assuming that after t week, the stock has been sold for $180.

Since the stock value increased at 5% every week, so, the interest is compounded weekly, so

S=C\left(1+R\right)^t \\\\ \Rightarrow 180 = 120\left(1+0.05\right)^t \\\\  \Rightarrow 180 = 120\left(1.05 )^t \\\\

\Rightarrow \frac{180}{120}=1.05^t \\\\\Rightarrow 1.5=1.05^t

\Rightarrow \ln(1.5)=t \ln(1.05) [taking log both sides]

\Rightarrow t=\frac {\ln(1.5)}{\ln(1.05)}=8.31 weeks

Hence, after 8.31  weeks the stock has been sold for $180.
