Answer:
Since , the superhero makes it over the building.
Step-by-step explanation:
The height is given by the following function:
Will the superhero make it over the building?
We have to find if there is values of x for which f(x) = 612.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
If , the polynomial has no solutions.
In this question:
We have to find
We have that . So
Since , the superhero makes it over the building.
Sin 30 = 16/x
x = 16/sin 30 = 32
The answer is d: 32.
Answer:
2(0) + 5 > 5
2(1) + 5 > 7
2(2) + 5 > 9
Step-by-step explanation:
Answer: see below
<u>Step-by-step explanation:</u>
The coordinates on the Unit Circle are (cos, sin). Since we are focused on cosine, we only need to focus on the left side of the coordinate. The cosine value (left side) will be the y-value of the function y = cos x
Use the quadrangles (angles on the axes) to represent the x-values of the function y = cos x.
Quadrangles are: 0°, 90°, 180°, 270°, 360° <em>(360° = 0°)</em>
Together, the coordinates will be as follow:
