So, BC = 5.6 cm

Step-by-step explanation:

Since its a right angled triangle,

taking 62 as reference angle,

cos62 = b/h

or, cos62 = AB/BC

or, cos62 = AB/12cm

or, cos62×12cm = BC

so, BC = 5.63

A taxi ride costs p40.00 for the first 500 meters and each additional 300 meters or a fraction there of adds p3.50 to the fare.u
Zarrin [17]

The function which represents the taxi fare in terms of distance d in meter is f(d) = 3.50 ×\frac{d-500}{300} + 40 .

According to the question,

For first 500 meters cost is  40.00 and For each additional 300 meters cost is 3.50 .

Let, the total distance of taxi ride = d meters

Now, representing the equation of taxi fare in terms of distance when distance is less than 500

taxi fare = 3.50 ×  \frac{d-500}{300}  + 40

∴  f(d) = 3.50 ×  \frac{d-500}{300} + 40

Assume ABC Company deposits $90,000 with First National Bank in an account earning interest at 6% per annum, compounded and semi
Brilliant_brown [7]

Answer: A) $120,953

Step-by-step explanation:

The formula to calculate the compound amount (semi-annually):-

A=P(1+\dfrac{r}{2})^{2n}, where P is principal amount , r is rate of interest and n is the number of time periods.

Given : Principal amount : P= $90,000

Rate of interest : 6% per annum = 0.06 per annum

Time period : n= 5 years

A=(90000)(1+\dfrac{0.06}{2})^{2\times5}=120952.474141\approx 120,953

Hence, the ABC will have $ 120,953 in the account after five years if interest is reinvested.
