Find the equation of the circle with center (4, 4)

1 answer:

madam [21]3 years ago

General equation of a circle is (x+a)^2 + (y+b)^2 = radius ^2
a and b are the centre and you put in the inverse so as x=-4, a=-4. same for b as the y-coordinate is positive, it becomes negative
the last part is the radius of the circles squared so just 7^2 = 49 !

You can model that you expect a 1.25% raise each year that you work for a certain company. If you currently make $40,000, how ma

Answer:

94 years

Step-by-step explanation:

We can approach the solution using the compound interest equation

$A= P(1+r)^t$

Given data

P= $40,000

A= $120,000

r= 1.25%= 1.25/100= 0.0125

substituting and solving for t we have

$120000= 40000(1+0.0125)^t \\\120000= 40000(1.0125)^t$

dividing both sides by 40,000 we have

$(1.0125)^t=\frac{120000}{40000} \\\\(1.0125)^t=3\\\ t Log(1.0125)= log(3)\\\ t*0.005= 0.47$

dividing both sides by 0.005 we have

$t= 0.47/0.005\\t= 94$
