Answer:
Step-by-step explanation:
We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).
First, recall that the equation of a circle is given by:
Where (<em>h, k</em>) is the center and <em>r</em> is the radius.
Since our center is at (7, 2), <em>h</em> = 7 and <em>k</em> = 2. Substitute:
Next, the since a point on the circle is (2, 5), <em>y</em> = 5 when <em>x</em> = 2. Substitute:
Solve for <em>r: </em>
<em />
<em />
Simplify. Thus:
Finally, add:
We don't need to take the square root of both sides, as we will have the square it again anyways.
Therefore, our equation is:
Answer:
3589 feet
Step-by-step explanation:
The horizontal distance from the helicopter to the landmark is 3589 feet.
Answer:
12x + 15y
Step-by-step explanation:
3 x 4x= 12x
3 x 5y = 15y
Answer:
3 into g into 5 into h
in this we will group the term 3 and 5 together and then the g and h
so the answer will be 3 into 5 into g into h = 15gh
Well the formula for the area of a trapezoid is as follows:
A=
where
a and
b are both base measures (a trapezoid has a top and bottom base)
.
Therefore, if all three have the same base length (the top and bottom lengths themselves being different yet the same on all three), the trapezoid with the greatest angle measure would have the greatest are. This is because with a greater angle measure comes a greater height (Pythagorean theorem).<span />
