The Pythagorean Theorem: (a² + b² = c²)
1. Substitute the known values
20² + 15² = c²
400 + 225 = 625
2. Solve
625 = c²
Divide and solve for both side, simplify and you get:
Answer: C = 25
A is the correct answer. By drawing two arcs from the two end points and drawing a line down the middle of the arc, you are creating a line that is at right angles with line AB. It is also in the midpoint. This makes it a perpendicular bisector.
Answer:
(-3, -9) and (4, 19)
Step-by-step explanation:
When X = -3
Y = 4x + 3
Y = 4(-3) + 3
Y = -12 + 3
Y = -9
When x = 4
Y = 4x + 3
Y = 4(4) + 3
Y = 16 + 3
Y = 19
Answer:
-4
Step-by-step explanation:
plug in -2
-(-2)^2 = -4
Answer:
<em>(675°F − 32) × 5/9 + 273.15 = 630.372K </em>
Hope it's right if not so sorry :)
