60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.
Answer:
Centre is (4,2) and radius is 10
Step-by-step explanation:
The circle equation is of form,
=> (x - a)² + (y - b)² = r²
where the centre is (a,b) and radius is 'r'.
Answer:
39π cm
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here r = 19.5, thus
C = 2π × 19.5 = 39π cm
If the rate of decay is 6% per year, that means the motorcycle retains 93% of its value every year. Because there are 12 months in a year, you can use the following equation:
x^12 = 0.94,
where x = the rate of decay each month, 12 = the number of months, and 0.94 = the retained value each year. Next, set a logarithmic function on each side as such:
LOG(x^12) = LOG(0.94)
When applying log functions, exponentials (like the 12 in the equation) are moved outside of the function like so:
LOG(x^12) = 12(LOG(x))
Therefore,
12(LOG(x)) = LOG(0.94) = -0.0268721464
When you divide both sides by 12, the equation becomes
LOG(x) = -0.00223934553
Finally, remove the LOG from the left side by applying both sides of the each by 10^() as such:
10^(LOG(X)) = 10^(-0.00223934553)
X = 0.994856987
Therefore, the motorcycle retains that 0.994856987 of its value every year.
1 - 0.994856987 = 0.005143
Expressed as a percentage, this value is 0.5143013%
