Answer:

(x+2) ^2 + (y-5)^2 = 36

Step-by-step explanation:

The equation of a circle can be written as

(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

The radius would be from 5 to -1 = 6 units

(x--2) ^2 + (y-5)^2 = 6^2

(x+2) ^2 + (y-5)^2 = 36

We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

$\frac{S}{356} = \sqrt{d}$

Square both sides to get rid of the square root:

$\frac{S^2}{126736} = d$

Now plug the known value of the speed to find the distance:

$d = \frac{140^2}{126736} = \frac{19600}{126736} \approx 0.15465$

So the closest answer is the last one: d=0.155km

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 55 pounds each, and the small boxes

nikdorinn [45]

Answer:

The number of large boxes is 55 and the number of small boxes is 70

Step-by-step explanation:

<u><em>The complete question is</em></u>

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes weigh 20 pounds each. There are 125 boxes in all. If the truck is carrying a total of 4150 pounds in boxes, how many of each type of box is it carrying?

Let

x ------> the number of large boxes

y -----> the number of small boxes

we know that

$x+y=125$ -----> equation A

$50x+20y=4,150$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (55,70)

therefore

The number of large boxes is 55 and the number of small boxes is 70

The students in a club are selling flowerpots to raise money. Each flowerpot sells for $21. Part A Write an expression that repr

scoundrel [369]

Answer: y = 21x

Step-by-step explanation:

y in this expression represents the total amount of money, in dollars, the students raise from selling x flowerpots.

21 is the price of each flower pot.

x is the number of flower pots sold.

If for instance, they sold 30 flower pots, y(total amount in dollars) would be;

= 21x

= 21 * 30

= $630
