Answer:
(0, 1/3)
Step-by-step explanation:
You find the y-intercept when the x value is 0, so plug in 0 for x and simplify
f(x) = -(2/9)(0) + 1/3
f(x) = 1/3
The y-intercept is at the point (0, 1/3)
Differentiate both sides with respect to , treating as a function of :
At the point (0, 0), the derivative is
The school bus will take 5.34 seconds to travel 95.1 m if the bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s².
<h3>What is a quadratic equation?</h3>
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have:
A school bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s².
From the second equation of motion:
We have given:
s = 95.1 m
u = 26.8 m/s
a = 4.73 m/s²
The above equation is a quadratic equation:
After simplification:
t = 5.373 seconds ≈ 5.34 seconds
Thus, the school bus will take 5.34 seconds to travel 95.1 m if the bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s².

Answer:
225° or 315°
Step-by-step explanation:
If sin Ф = -1, Ф must be in Quadrant III or Quadrant IV.
sin Ф = (opposite side) / hypotenuse. The opposite side is negative only in Quadrant III and Quadrant IV.
The angle Ф is either 225° or 315°
