Its D because the number shaded is 6 and circles 8 that is 6/8 and decimal vesion 0.75 in D there was 3/4 its 0.75 so D is your answer
Answer:
It passes through the point (3,4). Given that the center of the circle is the point (0,0). We know that the equation of the circle is given by : (x-a)^2 + (y-b)^2 = r^2 where (a,b) is the center and r is the radius.
The starting salary is $35,000.
Salary is increased by 6% at the end of every year.
Nos of years worked = 16 years
Total salary earned in 16 years is given by An * (( 1+i )^n - 1 ) / i
Where, An = Present Salary = $35000
i = Increase in salary per year = 6% = 0.06
n = number of years = 16
= 35000 * ( 1.06 ^16 - 1 ) / .06
= 35000 * ( 2.54035 - 1 ) / .06
= 35000 * 1.54035 / .06
= 898538
Total earnings in 16 years is $ 898538
So, the area of a rectangle is <span>LxW. </span>For this rectangle, <span>LxW=320. </span>We also know that the length is 4 feet longer than the width, that is L=W+4. With some substitution, we get<span>(W+4)W=320. </span>Simplify to get <span>W^2+4w=320. </span>Now the fun part! When we complete the square, we'll end up with (W+___)^2, right? So, let's take half of 4, which is 2, and square it. That's 4. Add that 4 to what we already have:W^2+4W+4. But remember, what we do to one side of an equation we must do to the other side. So we really have <span>W^2+4W+4=320+4.</span>We simplify and get <span>W^2+4W+4=324. </span>Factor the left side of the equation and get<span>(W+2)^2=324. </span>When we take the square root of both sides of the equation we getW+2=18, so W=16, which means the length (4 ft longer) is 20 ft. Do you have questions about the completing the square part? In a trinomial, the coefficient in the x term is the sum of the two factors and the constant term is the product. So, in the completing the square, you have the sum of a number added to itself or 2 times that factor. That's why we take half of it. Then, we square it to get the constant term. Square completed. But don't forget to keep the balance in the equation by also adding the constant term to the other side.
What’s the question exactly? :)
