Answer:
f(0) = 2
Step-by-step explanation:
Read from the graph the value "y" that the line presents when "x" is zero. That is the f(0) you are looking for.
See attached screen capture with the point highlighted
f(0) according to the image provided is equal to 2.
f(0) = 2
First, we have two points and we need to use these points to find the slope. To do this, let's label one point x1 and y1, the other point x2 and y2 then,
Slope = (y2 - y1) / (x2 - x1)
(2, 3) - 2 is x1 and 3 is y1
(-1, -12) -1 is x2 and -12 is y2
Slope = (-12 - 3) / ( -1 - 2) = -15 / -3 = 5
Now the equation of our line is: y = 5x + b
Let's plug one of our points into this equation to solve for b.
3 = 5(2) + b
3 = 10 + b
Subtract 10 from both sides.
-7 = b
The equation of our line is: y = 5x - 7
<span>The statement about "The function F(x) = 6x-2/5 is an example of a rational function." is false. The answer is letter B. The definition of a rational polynomial is that it is written in a form in which a polynomial is divided by a polynomial. Yes, 6x - 2 is a polynomial, a binomial to be precise but the 5 itself is not. It is not a polynomial, let alone a monomial because it does not contain a variable x or y. It is only a number. And so the statement is false.

Answer:
$25.50
Step-by-step explanation:
8.50 is apparently 1/3 of his money, so he had 3*8.50 = 25.50
Step-by-step explanation:
Cos A = 40^2 + 25^2- 34^2 ÷ (2×40×25)
= 200+625-1156 ÷ (2000)
= 1069 ÷2000
Cos A = 0.5345
A= cos inverse 0.5345
A = 57.7
