Cos(11π/3)
=cos(660)
=cos(360+180+90+30)
=cos(60)
=1/2
*Use the trigonometric quadrants to figure out the answer (All, Sin, Tan, Cos). And create the 60 degree right angled triangle with an adjacent side 1 and a hypotenuse of 2.
Answer:
The possible values are a = -2.5 or a = 4.5.
Step-by-step explanation:
Composite function:
The composite function of f(x) and g(x) is given by:
In this case:
So
Value of a so that the y-intercept of the graph of the composite function (fog)(x) is (0, 25).
This means that when 
. So
Solving a quadratic equation, by Bhaskara:
The possible values are a = -2.5 or a = 4.5.
I believe that the answer to that one would be A.
Answer:
I. 94.99 in²
II. $0.23
Step-by-step explanation:
<u>Given the following data;</u>
Diameter of wheel = 11 inches
Cost of wheel = $21.35
<em><u>Part A</u></em>
To find the area;
We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;
Substituting into the equation, we have;
<em>Area, A = 94.99 in²</em>
<em><u>Part B</u></em>
To find cost per square inch;
<u>Cost per square inch = $0.23</u>
