Find the value of x to the nearest tenth.

nlexa [21]

Answer:

x = 14.7

Step-by-step explanation:

Using the sine rule

$\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}$

Substitute the given values.

$\frac{7}{sin(20)} = \frac{x}{sin(46)}$

Rearrange the equation to get x on it's own.

$\frac{7sin(46)}{sin(20)} = x$

x = 14.72246211

x = 14.7 (1dp)

6000 for 6 years at 81/2 % compounded daily will grow to a) $9.990.02 b)9.060.00 c) 9788.81 d)9991.15

Flura [38]

Answer:

d)9991.15

Step-by-step explanation:

We have a sum of money ($6000) compounded daily at an annual interest rate of 8.5% for 6 years.

If the interest is compound daily, and we take a m=365 days a year (or 365 subperiods m), the daily nominal interest rate is:

$i_d=\dfrac{i}{m}=\dfrac{0.085}{365}=0.000232877$

Then, we can express the final valueo of $6000 compounded daily at an annual interest rate of 8.5% for 6 years as:

$FV=IV\left(1+\dfrac{i}{m}\right)^{n\cdot m}\\\\\\FV=6000(1+0.000232877)^{6\cdot 365}\\\\FV=6000(1.000232877)^{2190}\\\\FV=6000\cdot1.665192322\\\\FV\approx9991.15$
