Answer:
Step-by-step explanation:
im guessing you need the equation of the circle?
plugging it into the standard circle equaition you would get (x+9)^2+y^2=1 and then you would just need to rearaange it into standard form
Answer:
the darkest shaded one.
Step-by-step explanation:
because the two areas for possible answers both intersect at that area, therefore, that is the answer.
Answer:
maximum height of the arrow will be 408 m
Step-by-step explanation:
We have given the function of height as
We know that first derivative of height will be velocity
So first derivative of height
We know that at maximum height velocity will be zero
t = 5 sec
Sp arrow will be at maximum height at t = 5 sec
So height at t = 5 sec will be
So maximum height of the arrow will be 408 m
Since and , we can rewrite the right side of the equation as
Using the identity , we can subtract from either side to obtain the identity
substituting that into our previous expression, the right side of our equation simply becomes
We can now write our whole equation as
Adding 2 to both sides:
dividing both sides by 3:
When 0 ≤ x ≤ π, tan x can only be equal to 1 when sin x = cos x, which happens at x = π/4, and it can only be equal to -1 when -sin x = cos x, which happens at x = 3π/4
