Answer:
The Mark's average speed was
Step-by-step explanation:
we know that
To find out the average speed, divide the total distance by the total time
Let
s -----> the average speed in miles per hours
x ----> the total distance in miles
y ----> the total time in hours
we have
substitute
Answer:
B
Step-by-step explanation:
The equation of a line parallel to the x- axis is
y = c ← standard form
Where c is the value of the y- coordinates the line passes through
here the line passes through (1, 4) with y- coordinate of 4, hence
y = 4 ← is the equation of the horizontal line
Answer:
1/3 - (-5/3) = 2
Step-by-step explanation:
1/3 - (-5/3)
Subtracting a negative is the same as adding a positive.
1/3 + 5/3 = 6/3, or 2
Answer:
44.5 ft
Step-by-step explanation:
Reference angle = 39°
Opposite = x
Adjacent = 55
Apply trigonometric function TOA:
Tan 39 = Opp/Adj
Tan 39 = x/55
55 × Tan 39 = x
44.5381218 = x
x ≈ 44.5 ft
