Answer:
- Equation: 32° + 30° + x° = 180°
- Solved: x = 118°
Step-by-step explanation:
- 3 angles = 180°
- 32° + 30° + x° = 180°
- 62° + x = 180°
- Subtract 62 from each side, so it now looks like this: x = 118°
- So, x is 118°
I hope this helps!
Answer:
=−17265
Step-by-step explanation:
(−5)3(125)−1515−125
=−17265
Remember the shortcut way for graphing quadratic equations
- A quadratic function has graph as parabola
- Hence on both sides of vertex the parabola is symmetric and axis of symmetry is vertex x values .
- y on both sides for -x and +x is same
#1
Vertex
As a is positive parabola facing upwards
Find y for same x distance from vertex
I took 3-1=2 and 3+1=4
- f(2)=2(2-3)²-1=2(-1)²-1=2-1=1
- f(4)=2(4-3)²-1=1
Now plot vertex and these two points (2,1) and (4,1) on graph then draw a parabola by freehand
#2
- y=(x-2)(x+4)
- y=x²+4x-2x-8
- y=x²+2x-8
Convert to vertex form
Vertex at (-1,-9)
Same take two equidistant x values
Let's take -1-1=-2 and -1+1 =0
- f(-2)=(-2+1)²-9=1-9=-8
- f(0)=(1)²-9=-8
Put (-1,-9),(-2,-8),(0,-8) on graph and draw a freehand parabola
#3.
Yes it can be verified by finding the coordinate theoretically on putting them on function then can be verified through putting them on graph whether they matches or not
I think the answer is false. It is not correct.
Answer:
(1)
Step-by-step explanation:
The inscribed angle RTS is half the measure of its intercepted arc RS, so
∠ RTS = 
× 64° = 32°
