Answer:
The given statement:
The expression cos^-1 (3/5) has an infinite number of values is a true statement.
Step-by-step explanation:
We are given a expression as:
Let us equate this expression to be equal to some angle theta(θ)
i.e.
Let
As we know that the limit point of the cosine function is [-1,1]
i.e. it takes the value between -1 to 1 and including them infinite number of times.
Also,
-1< 3/5 <1
This means that the cosine function takes this value infinite number of times.
That is there exist a infinite number of theta(θ) for which:
i.e. the expression:
has infinite number of values.
Answer: 100
Step-by-step explanation:
(10^-3)(10^5)
1/10^3*10^5 (I applied the negative power rule x^-a=1/x^a)
1/1,000*10^5
1/1,000*100,000
100,000/1,000=100
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! I also hope you had a great Superbowl Weekend! :-)

Answer:
see explanation
Step-by-step explanation:
The area (A) of the sector of a circle is
A = area of circle × fraction of circle
= πr² × 
diameter = 12.4 ⇒ r = 6.2, thus
A = π × 6.2² × 
= π × 38.44 ×
= 
≈ 20.13 m² ( to 2 dec. places )
Answer: f(-3) = 9
Step-by-step explanation:
Plug in -3 for x
f(-3) = (-3)^2
Square -3
(-3)^2 = 9
Answer:
∠KNC and ∠KMC are right angles
∠MCN = 25°
Step-by-step explanation:
if KM and KN are tangent lines, then they are perpendicular to the radius going through the tangent point, so therefore right angles are:
1. ∠KNC
2. ∠KMC
the outside angle of a circle is equivalent to half the measure of the intercepted arc, so
if ∠MKN = 50°, then ∠MCN = 25°
