Answer:
peregrine falcon
Step-by-step explanation:
you convert the 61.6 feet to miles which is 0.01166667 miles. you multiply that by the seconds in an hour(3600)
so 0.01166667*3600 = 42 miles an hour 75>42
Answer:
2x-3
Step-by-step explanation:
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)
m = = = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using B(2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
Given: 15.6 mph South (-15.6)
7.1 mph West (-7.1)
We will use the negatives when we calculate the angle South and West are both in the negative direction
find the resultant vector using Pythagoras
15.6^2 + 7.1^2 = C^2
278.42 = c^2
c = 16.69 mph
now to find the angle
take the tan^-1 (-15.6/-7.1) = tan^-1 (2.197)
angle = 65.5 degrees
add to 180 since in 3rd quadrant
angle is 245.5 degrees
result is (16.69, 245.5)
