Answer:
Step-by-step explanation:
Given:
m∠NPT = m∠TNM = 50°
To prove:
ΔNMT ~ ΔPMN
Solution:
Statements Reasons
1). m∠NPT = m∠TNM 1). Given
2). ∠NMP ≅ ∠NMP 2). Reflexive property
3). ΔNMT ~ ΔPMN 3). By AA property of similarity of two
triangles
468=40x+18(x-3)
468=40x+18x-54
468=58x-54
522=58x
9=x
I'm not sure if you need to know x at all, if not, the top equation is all you need.
Answer:
1. r=17
2. (-15,14) or (-15,-16)
Step-by-step explanation:
The radius of the circle is the distance from the center to the point on the circle, thus

The equation of the circle is

If point lies on this circle, then its coordinates satisfy the circle's equation:

Answer:
The answer is B) y = Sin(3x)
Step-by-step explanation:
In order to find this, you need to look for how long it takes the period to repeat. This means other than the origin, we need to find the next place that the graph hits y = 0. In this case, it is at 2
/3. Since Sin2
= 0, we need what is inside of the parenthesis to equal 2
.
The only thing that you could multiply 2
/3 by to get 2
m is 3. Therefore, we must have 3x in the original equation.
