Answer:
10 cm
Step-by-step explanation:
The diameter is a chord (line) that connects on both ends of a circle which includes the center point of the circle. The radius comes from the center point of the circle to one end of the circle.
Diameter is therefore 2 radii (radius).
So if diameter is given and you want to find the radius, divide it by two to find the answer.
20 ÷ 2 = 10 cm
Answer: You can't answer this, but here are some guidelines
Step-by-step explanation:
I would love to answer this question (coming from someone who has already completed algebra keystones) but I need to know what the linear equations are before I can. If the functions are reciprocals of one another (the slope is the opposite and the fraction is switched) it is a perpendicular line which means one solution. If the slope is the same but the intercept is different (using y=mx+b) so if b is different but m is the same they are parallel and there is no solution. If they are the same line (same equation) there is infinite solutions. If this doesn't help I would suggest finding graph paper and trying it out and seeing the intersection points.
Answer:
f(g(x)) = 72x^2+1
Step-by-step explanation:
f(x) = 2x^2 +1
g(x) = -6x
f°g(x) means f(g(x))
Take g(x) and substitute it in for x in f(x)
f(g(x)) = 2(g(x))^2 +1
=2(-6x)^2 +1
=2(36x^2) +1
=72x^2 +1
The third statement is correct.

All
isosceles triangles are not similar. The pair of congruent angles
within one triangle is not necessarily congruent to the pair of
congruent angles within the other triangle.
