Answer:

$Angle = 54$

Step-by-step explanation:

Given

Kano = 45;

Kwara = 410;

Ogun = 105;

Ondo = 126;

Oyo = 154

Total Distribution = 840

Required

Determine the angle subtended by Ondo (in a pie chart)

The general formula to calculate subtended angle in a Pie chart is;

$Angle = 360 * \frac{Frequency}{Total\ Frequency}$

In this case of Ondo

Frequency = 126

Total Frequency = Total Distribution = 840

Substitute these values in the given formula;

$Angle = 360 * \frac{126}{840}$

$Angle = \frac{360 *126}{840}$

$Angle = \frac{45360}{840}$

$Angle = 54$

<em>Hence, the angle subtended by Ondo is 54</em>

Travka [436]

Answer: $RM 31631$

Step-by-step explanation:

We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:

$RM 57000(\frac{8}{9})^{n}$

Where $RM 57000$ is the price of the car when it was bought new, and $n=5$ is the number of years the car was used.

Solving the formula with the given data:

$RM 57000(\frac{8}{9})^{5}=RM 31630.95$ This is the value of the car according to the formula.

However, this value can be approximated to:

$RM 31631$

$(sin\theta+sec\theta)^2+(cos\theta+cosec\theta)^2=(1+sec\theta\ cosec\theta)^2\\\\L=sin^2\theta+2sin\theta\cdot\frac{1}{cos\thewta}+\frac{1}{cos^2\theta}+cos^2\theta+2cos\theta\cdot\frac{1}{sin\theta}+\frac{1}{sin^2\theta}\\\\=(sin^2\theta+cos^2\theta)+\frac{2sin\theta}{cos\theta}+\frac{2cos\theta}{sin\theta}+\frac{1}{cos^2\theta}+\frac{1}{sin^2\theta}$

$=1+\frac{2sin^2\theta+2cos^2\theta}{sin\theta\ cos\theta}+\frac{sin^2\theta+cos^2\theta}{sin^2\theta\ cos^2\theta}\\\\=1+\frac{2(sin^2\theta+cos^2\theta)}{sin\theta\ cos\theta}+\frac{1}{sin^2\theta\ cos^2\theta}\\\\=1+\frac{2}{sin\theta\ cos\theta}+\frac{1}{sin^2\theta\ cos^2\theta}\\\\=1^2+2sec\theta\ cosec\theta+sec^2\theta\ cosec^2\theta\\\\=(1+sec\theta\ cosec\theta)^2=R$
