A) The exact area is just the difference between the two numbers:
2.69-2.67 = 0.02 units
b) Calculate the area of the circle with the two values for the radius:
A = <span>πr^2 = </span><span>π * 2.69^2 = </span>22.7328786 units squared
A = πr^2 = <span>π * 2.67^2 = 22.39609987 units squared
</span> Then, find the difference between the two numbers:
22.7328786 - 22.39609987 = 0.336778731 <span>≈ 0.34 units squared (2.s.f.)
c) I'm not sure what the question is asking for (perhaps the rounding expressed </span><span> at the end of b?)
d) The relative error is the absolute (exact) error divided by the actual value for </span><span> the radius:
</span> 0.02/2.67 = 0.007490636704 ≈ 0.0075 (2.s.f.)
The percentage area is the absolute (exact) error divided by the actual value for the area, and then multiplied by 100 to find a percentage:
(0.336778731/22.39609987)*100 = 1.503738298 <span>≈ 1.50% (2.s.f.)</span>

Answer:
x-intercept: (-3,0)
y-intercept: (0,-3)
Step-by-step explanation:
Looking at the equation, we can see that it is already in standard form, or in a 
format. Whenever a line is put into standard form, the x-intercepts are represented by 
and the y-intercepts are represented by 
. So, let's calculate them by doing the following:
1) Find the x-intercept by using the formula. Substitute the number on the right side of the equation for 
and the coefficient for the x term for 
. So, in this case, 
and 
:
Therefore, the x-intercept is (-3,0).
2) Next, find the y-intercept by using the 
formula and substituting the right values. is still the number on the right side of the equation and 
is the coefficient of the y term. So, and 
.
Therefore, (0, -3) is the y-intercept.
