Answer:
b) true
c) false
d) true
e) true
Step-by-step explanation:
b) Any line that contains an interior point of a circle is a secant of the circle. The center is an interior point, so a line that contains the circle center is a secant.
__
c) Chords of different lengths intercept arcs of different measures
__
d) Any line perpendicular to a radius at the point where the radius meets the circle is a tangent to the circle. The endpoint of a diameter is the endpoint of a radius, so a line perpendicular there will be a tangent.
__
e) The measure of an inscribed angle is half the measure of the intercepted arc, so all inscribed angles that intercept equal arcs are equal.
Answer:
Step-by-step explanation:
What sets a vector apart from a scalar is that the vector has both magnitude (length) and direction, whereas a scalar has only magnitude, no direction.
The answer is 42/3
4 2/3 × 6 1/2= 30.33 (30 1/3)
Step-by-step explanation:
The derivative of log is
You can easily derive this using the Change of base rule, and natural log rules
Next, we differentiate with respect to x.
So back to the topic at hand,.
a=7, so we get
We plug in 0, we would get undefined
