ira [324]

Answer:

$y\approx75.0$ is the correct answer.

Step-by-step explanation:

$\tan \left(30^{\circ \:}\right)=\frac{x}{150}\quad :\quad x=50\sqrt{3}\quad \left(\mathrm{Decimal}:\quad x=86.6\dots \right)\\\\\sin \left(60^{\circ \:}\right)=\frac{y}{86.6}\quad \rightarrow\quad y\approx75$

Help!!!!

joja [24]

Answer:

0.28 yr

Step-by-step explanation:

To find the doubling time with continuous compounding, we should look at the formula:

$FV = PVe^{rt}$

FV = future value, and

PV = present value

If FV is twice the PV, we can calculate the doubling time, t

$\begin{array}{rcl}2 & = & e^{rt}\\\ln 2 & = & rt\\t & = & \dfrac{\ln 2}{r} \\\end{array}$

1. Samuel's doubling time

$\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.055}\\\\& = & \textbf{12.603 yr}\\\end{array}$

2. Claire's doubling time

$\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.05625}\\\\& = & \textbf{12.323 yr}\\\end{array}$

3. Samuel's doubling time vs Claire's

12.603 - 12.323 = 0.28 yr

It would take 0.28 yr longer for Samuel's money to double than Claire's.

Show work, for extra Brainly, elementary work, multiplying unit fractions by whole numbers

Wewaii [24]

Answer:

2 1/4

Step-by-step explanation:

Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.

To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.
