Answer:
(3,13)
Step-by-step explanation:
so, you would add 3 to the y value
the point would be (3,13)
Answer:
920 miles
Step-by-step explanation:
<em>Distance from New York City to Boston Massachusetts = 187 miles</em>
<em>Distance from Boston to Philadelphia, Pennsylvania = 273 miles</em>
Total Distance of one side = 187 + 273
Total Distance of one side = 460 miles
<em>The return distance will be the same that is 460 miles.</em>
Total Distance of both sides = 460 + 460
Total Distance of both sides = 920 miles
Therefore, the plane flew total 920 miles.

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>
The correct answer is 54.3.
