Answer:

24.8 mph

Step-by-step explanation:

as we know if one sailed north and another east, the angle with respect to the port will be 90 degrees

This means that the distance of each ship to the pier can be the legs of a rectangular triangle

The distance of a ship from the other would be represented by the hypotenuse

h: Hipotenuse

c1: leg 1

c2: leg 2

By Pythagoras we know that the hypotenuse is equal to

h = √(c1^2 + c^2)

if we replace with the values ​​we have left

h = √(18^2 + 17^2)

h = √(324 + 289)

h = √613

h = 24.758

we round a decimal place

h = 24.8

The y- intercept has to be a point in the line where x is 0. Which means that in this case it would be -4.
To find the slope, use the formula: rise over run —> y2 - y1/x2 - x1
Choose any two coordinates and plug them in. Then simplify. Let me know if you have any questions by commenting:)
Hope I helped:)

What is the sequence of second differences for ax +b?
MAVERICK [17]

Answer:

ZERO

Step-by-step explanation  

Write the given function as

F(x) = ax + b

i.e Y = ax + b

now differentiate Y with respect to X

dY/dX = d (ax + b)/ dx

dY/dX = a

now again differentiate this function with respect to x

so,  d^2Y/dX^2 = d^2 (a)/dX^2

                         = 0 (ZERO)

note: differentiation of constant function is zero

Determine whether the triangles are similar by AA, SSS, SAS, or not similar
Anton [14]

Answer:

Step-by-step explanation:

If Δ JKL ~ Δ JHG , then

\frac{LJ}{GJ} = \frac{KJ}{HJ}

\frac{95}{68} ≠ \frac{87}{72} ⇒ triangles are not similar
