The Pythagorean Theorem What is the value of c in the right triangle?
c? = a2 + b2
12
C2 =
+42
с
C2 = 9+
a = 3
c2 = 25
C=
b = 4
For the square root you do get a positive and a negative value, but we only
use the
value here because we're dealing with side
lengths of a triangle

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a> 1
