Answer:
D. b = 128
Step-by-step explanation:
Find the diagram to the question attached.
From the diagram, line p is parallel to line q i.e p//q
You must understand that the angle at the opposite side of the transversal are equal i.e alternate angle.
From the diagram, <b = 118° (alternate angle)
Hence option D is correct

Answer:
The answer is given below
Step-by-step explanation:
A number is said to be a zero of a polynomial if when the number is substituted into the function the result is zero. That is if a is a zero of polynomial f(x), therefore f(a) = 0.
Since P(−1)=0 P(0)=1 P(2+√3)=0, therefore -1 and 2+√3 are zeros of the polynomial.
Gary is right because there are 2 known zeros of P(x) which are −1 and 2+√3. Also 2 - √3 is also a root. From irrational root theorem, irrational roots are in conjugate pairs i.e. if a+√b is a root, a-√b is also a root.
Heather is not correct because if P(0) = 1, it means that 0 is not a root. It does not mean that 1 is a zero of P(x)
Irene is correct. since P(−1) and P(2+3–√) equal 0, 2 zeros of P(x) are −1 and 2+√3. They may be other zeros of P(x), but there isn't enough information to determine any other zeros of P(x)
But what are the answer choices
Answer:
The profit in this case is equal to $50,700.
Step-by-step explanation:
As the problem stated profit is the difference between revenue and cost, in this case we have:
So the profit will be the difference between these two functions.
In order to find the profit when 150 televisions are sold we need to make x equal 150.
The profit in this case is equal to $50,700.
