Answer:

<u>Given circle:</u>

  • (x - 4)² + y² = 25

The center is at (4, 0) and the radius is 5 units

<u>Lets find the distance from (7, 2) to the center of the circle:</u>

  • <u />d = \sqrt{(7 - 4)^2 + (2 - 0)^2}  = \sqrt{9+4} = \sqrt{13} < 5

Since d < 5, the point (7, 2) lies <u>inside</u> the circle

2x +1 &lt; 5 what would be the inequality for this ?
Juli2301 [7.4K]

Hey there!


2x + 1 < 5

SUBTRACT 1 to BOTH SIDES

2x + 1 - 1 < 5 - 1

SIMPLIFY IT!
2x < 5 - 1

2x < 4


DIVIDE 2 to BOTH SIDES

2x/2 < 4/2

SIMPLIFY IT!
x < 4/2

x < 2


Therefore, your answer is: x < 2

(The graph is down below)


Good luck on your assignment & enjoy your day!

In the smaller triangle, let y be the length of the smallest leg. Then the smallest leg in the larger triangle is 14-y.

Within the scope of the smaller triangle, we have y such that

x^2+y^2=13^2\implies y=\sqrt{13^2-x^2}

Then within the larger the triangle, we would have

x^2+(14-y)^2=15^2\iff x^2+\left(14-\sqrt{13^2-x^2}\right)^2=15^2

Now we can solve for x:

x^2+14^2-28\sqrt{13^2-x^2}+(13^2-x^2)=15^2

\implies x=12
