Equation of a circle in standard form with center (h,k) and radius r is given by :

(x-h)^{2} +(y-k)^{2} =r^{2}

In the given question the center of circle is lying on y axis so h=0 .Radius r=3 Substituting these values in the equation of circle we have:

(x-0)^2+(y-k)^2=3^2

Expanding we have :

x^2+y^2-2yk+h^2=9

Subtracting 9 both sides

x^2+y^2-2yk+h^2-9=0

Comparing this with the equation of circle in general form

A=1,B=1,C=0

If D=-8 then E=7

So option C is the right answer

two warehouse employees need to move microwave ovens and television that weigh 45 pounds and 85 pounds, respectively, using a fr
Zinaida [17]

The maximum number of microwave ovens the two employees can take on the elevator is 7.

<h3>How to find the maximum number of microwave ovens the two employees can take on the elevator?</h3>

To solve the question, we have to find the simple equation showing the relationship between all the weights an the maximum weight the elevator can carry

Let

  • x = number of microwave ovens

Since the micro wave weighs 45 pounds, the total weight of microwave ovens is W = 45x.

Also, there are 20 televisions on the elevator. If each television weighs 85 pounds, the total weight of televisions is W' = 20 × 85 = 1700 pounds

Also, the weight of the equipment and the two employees is W" = 400 pounds.

Since the maximum weight on the elevator is 2400 pounds, we have that the required simple equation is

W + W' + W" = 2400

45x + 1700 + 400 = 2400

45x + 2100 = 2400

45x = 2400 - 2100

45x = 300

x = 300/45

x = 6.67

x ≅ 7

So, the maximum number of microwave ovens the two employees can take on the elevator is 7.

A 20 ft ladder leans against a wall. The base of the ladder is 5 ft from wall. How high up the wall does the top of the ladder r
Archy [21]
Let h = height
h square = 20 square + 5 square
h square = 400+ 25
So you square root both sides
h = root 425
h = 20.6155281
