Answer: $5.41
Since you have find c, how much more the second poster costs, you have to subtract from $12.45.
12.45 - 7.04 = 5.41
Answer = $5.41
<u>Part 1: Finding radius</u>
The radius of a circle is defined as the distance from the center to a point on the circle's circumference.
Using the distance formula,
<u>Part 2: Finding the point with x-coordinate -15</u>
Let the y coordinate of the point be y. Then, we have the point (-15, y). Substituting into the distance formula,
Answer:
(2, 1 )
Step-by-step explanation:
Using the Section formula
For endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then coordinates of point are
[ , ]
Here m = 5, n = 2, (x₁, y₁ ) = (- 3, - 9), (x₂, y₂ ) = (4, 5), thus partitioned point
= [ , ]
= [ , ]
= ( , )
= (2, 1 )
