the answers are -12x^2 and 4x^2y. hopefully it helps and i just got it right.
The equation of the graph is given by y = cos(0.4x) and has an amplitude of 1
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Since the curve crosses the y-axis at y = 1, hence it is a cosine graph. It has a maximum of 1 and a minimum of negative 1, therefore the amplitude is 1
Also, the angular frequency = 2π * 1/5π = 0.4

The equation for finding the circumference of a circle:
If the radius of this circle is 1, then that means the diameter is 2. We multiply 2 by π to get our answer: 2π or approximately 6.283.
Answer:
y = 5x - 9
Step-by-step explanation:
y - y₁ = m(x - x₁), where (x₁, y₁) = (3, 6)
y - 6 = 5(x - 3)
y = 5x - 15 + 6
y = 5x - 9
