The two pieces are continuous for every
So, our only concern is to make sure that the pieces "glue" continuously at x=7.
To ensure this, we evaluate both pieces at x=7, and impose that the two values are equal.
The first piece evaluates to
The second piece evaluates to
So, we want
We move all terms involving c to the left hand side, and all the numerical constants on the right hand side:
Answer:
8hr;)
Step-by-step explanation:
All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Given that:
Sine function
being
Cosine function
being
We will demonstrate the identity above. First of all, we need to square each equation, so:
Adding these two equations:
But as shown in the figure, using Pythagorean theorem
is always equal to 1, then:
The relation to right triangles is that:
<span>The hypotenuse is always equal to 1
</span>The opposite side is equal to
The adjacent side is equal to
Answer:
NOT VERY LIKELY
Step-by-step explanation:
• 1/2 OF THE CLASS TOOK FORM A
• 1/2 = 50%
• THE CHANCE CANNOT BE OVER 50%
• 39% OUT OF 50% PASSED
• 50% - 39% = 11%
• THE ANSWER IS NOT VERY LIKELY
Answer:
9
Step-by-step explanation:
jerry-3 = molly
molly = 6
jerry - 3 = 6
jerry = 9
