Answer:
θ = 
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ = 
Sin θ = 
= 0.5
θ = 
0.5
θ =
Thus, the angle of elevation from the base to the top of the mountain is .
If Keith is represented by x, and Joe is three less than Keith, Troy is represented by x-3.
Then, we know that Joe exercises for twice the amount of time as Troy, we multiply the expression for Joe by two.
Keith = x
Troy = x-3
Joe = 2(x-3)
Answer:
Irrational numbers
Step-by-step explanation:
They Cant be an integer, because they are not on the common numberline of positive and negative numbers.
Answer:
x² + y² = 100
6² + 8² = 100
36 + 64 = 100
100 = 100
Because this is a true statement, the answer is yes, it does lie on the circle.
Answer:
-26042
Step-by-step explanation:
sum of a finite geometric series =
here, a1 is the first term, r is the common ratio, and n is the number of terms
a1 = -2
r = -5
n = 7
