Answer: Option A
Step-by-step explanation:
We can model the situation by means of a right triangle.
Where the angle 
is the angle that you make with the top of the TV.
Then the horizontal distance of 6 feet is the adjacent side and the vertical distance of 8 feet is the opposite side to the angle the.
By definition of the 
function we know that:
Therefore:
Answer:
the answer would be: 5-13c
The domain is the values of x from the x-axis that 'cover' the given function.
Look at the end points of the graph and the corresponding values of x on the x-axis. These go from - 5 to 4
Thus the domain is x ∈ [- 5, 4 ] ← domain
The square bracket indicates that the values of - 5 and 4 are included in the domain
Whereas (- 5, 4 ) indicates that - 5 and 4 are not included but all values in between are
The range is the values of y from the y-axis that cover the given function
Look at the minimum value and maximum value of the function along the y-axis
The minimum is 0 and the maximum is 5
range is y ∈ [0, 5 ]
To determine the value of y when x = -3
Locate x = - 3 on the x-axis, move up vertically until the line representing the function is met, and read off the corresponding y value to the right on the y-axis
The value of f(x) when x = - 3 is 2
Answer:
(x - 5)² = 39
Step-by-step explanation:
Given
x² - 10x = 14
To obtain an equivalent equation use the method of completing the square.
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 14 + 25
(x - 5)² = 39
We will study the convergence of the series
For
the series has constant general term which is divergent.
For
the series diverges since its general term goes to infinity as n goes to infinity.
For
, the series converges since it is equivalent to the Riemann series.
