It's too easy just to calculate the actual value:
726 × 5 = 726 × 10/2 = 7260/2 = 3630
_____
You might estimate the value as 700 × 5 = 3500. You might estimate that to be low by 26/700 ≈ 4%, so about 140.
The point (3/5,4) would lie on the circle if it makes the equation of the circle to be true
Latansha's equation of the circle is wrong
<h3>How to determine her error?</h3>
The given parameters are:
Center = (a,b) = (0,-2)
Radius, r = 7
The equation of a circle is:
This gives
Rewrite as:
In Latanya's first step, we have:
By comparing her first step with x^2 + (y + 2)^2 = 0, we can see that her equation is wrong
Hence, Latansha's error is that she determine the equation of the circle, wrongly.

Answer: -6x + -9y
Step-by-step explanation:
You just distribute the negative with each term
Answer:
Cannot be determined
Step-by-step explanation:
The information given for the triangles are not enough to evaluate them for similarity. How ever they are both equilateral triangles given the angle measures.
interest = principal x rate x time
interest = 1344-1200 = 144
principal = 1200
rate = 8% = .08
144 = 1200 x .08 x Time
Time = 1.5 yrs
