A leading bank is coming up with an investment that pays 8 percent interest compounded semiannually. What is the investment's ef

uranmaximum [27]

The effective rate is calculated in the following way:
$r = {(1 + \frac{i}{n} )}^{n} - 1$
where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
$r = {(1 + \frac{8\%}{2}) }^{2} - 1 \\ r = {(1 + \frac{1}{25}) }^{2} - 1 \\ r = \frac{676}{625} - 1 \\ r = 0.0816 \: or \: 8.16\%$

If QRST is a rectangle with QT = 30 and RS = 4x + 10, find x.

ArbitrLikvidat [17]

The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20
x=5

Sterile fruit flies are used in an experiment where the proportion that survives at least days is given by . if the experiment b

Nana76 [90]

Answer:

Number of fruit flies after 14 days is equal to 1880.

Step-by-step explanation:

given,

fruit flies at the beginning of the experiment = 200 fruit flies

rate of increase of fruit flies = 5 per hour

to calculate the number of flies after 14 days.

time = 14 days = 14 × 24 = 336 hours

flies after 14 days = initial number of flies + rate of increase × time

= 200 + 5 × 336

= 1880 fruit flies.

hence,Number of fruit flies after 14 days is equal to 1880.
