Answer:
-2
Step-by-step explanation:
The equation of a line in slope intercept form is
y = mx +b where m is the slope and b is the y intercept
y = -2x+4
The slope is -2 and the y intercept is 4
Answer:
1)
Independent variable: no. of passengers
Dependent variable: Average speed
2)
Inverse relationship
Fuel consumption increases as speed decreases
3)
Direct relationship
As the no. of passengers increase, fuel consumption also increases
4)
As the no. of passengers increase:
* speed decreases
* Fuel consumption increases
Answer:
Yes, they are equal in the values (in radians):
π/4, 5π/4
If cos(x) and sin(x) are defined to you as nonnegative functions (in terms of lengths), then 3π/4 and 7π/4 are also included
Step-by-step explanation:
Remember that odd multiples of 45° are special angles, with the same sine and cosine values (you can prove this, for example, by considering a right triangle with an angle of 45° and hypotenuse with length 1, and finding the trigonometric ratios).
The radian measure of 45° corresponds to π/4, hence the odd multiples on the interval [0, 2π) are π/4, 3π/4, 5π/4, 7π/4.
If you define sin(x) and cos(x) using the cartesian coordinate system (via unit circle), then cos(3π/4)=-sin(3π/4) and cos(7π/4)=-sin(7π/4). In this case, only π/4 and 5π/4 are valid choices.
Any polynomial's graph cannot have two simultaneous maxima, so they must contain a minima between them. Thus, the total number of turning points of the graph is 3. Generally, when plotting a polynomial, the number of turning points is:
n = d -1; where d is the degree of the polynomial and n is the number of turning points. Thus, this function's degree must be at least 4. The answer is b.
