A and B lie on the line, yes, but what specifically are you supposed to do? Looks like your problem statement was cut off before you'd finished typing it in.
You say your line passes thru (-2,5) and has a slope of 2/3? Then, using the point-slope formula,
y-5 = (2/3)(x+2) This is the general equation for your line.
Now let's play around with B(-2,y). Suppose we subst. the x-coordinate of B, which is -2, into the equation y-5 = (2/3)(x+2); we get y-5 = (2/3)(-2+2) = 0. This tells us that y must be 5. But we already knew that!!
So, please review the original problems with its instructions and this discussion and tell me what you need to know from this point on.
Answer:
<u>Frequency = 1/period = 
</u>
Step-by-step explanation:
The frequency of the sinusoidal function = 1/period
Frequency is how many the function repeats itself per unit if time i.e: per "1"
For the given graph :
, Where: B = 2π/period
period = 2π/B , B = 1/4 = 0.25
∴ Period = 2π/0.25 = 8π
∴ Frequency = 1/period =
Based on the vertex form equation, the statements that are true are:
A.) the drone reaches its minimum 25 miles from the launch site
C.) at its minimum, the drone’s depth is -180 meters.
<h3>Rewriting the equation in vertex form</h3>
Given:
x = horizontal distance, in miles, from the launch site
d(x)= depth below the surface of the water, in meters.
Equation= 0.4x ²- 20x + 70
Hence
Rewritten the given equation ( 0.4x ²- 20x + 70) in vertex form will be:
Vertex form: d(x)=[2(x-25)²÷5] -180
Vertex= -180, 25
Minimum=-180 at x=25
Therefore the correct option is A, C.

Answer:
V/(pi r^2) = d
Step-by-step explanation:
V = pi r^2 d
Divide each side by pi r^2
V/(pi r^2) = pi r^2 d/(pi r^2)
V/(pi r^2) = d
Then substitute the values into the equation to find d
