Answer:
slope is -5
Step-by-step explanation:

This equation is in slope-intercept form:

where m is the slope and b is the y-intercept.
In the given equation, the slope is -5 and the y-intercept is 1.
Answer: north 80 m/s
Explanation:
speed = distance/time = 56/0.7 = 80
Recall that velocity is composed of both the speed and the direction. In this case, the arrow is traveling 80 m/s to the north
A = 9/10
b = 1/3
c = 2/3
I dunno how to explain it properly but the question gives the fractions, you just need to find out what makes the other fraction that can equal to 10/10 for the first part, then 3/3 for the second part.
Answer:

Step-by-step explanation:
Given: A point is 
To find: function whose graph passes through the given point
Solution:
A trigonometry explains the relationship between the sides and the angles of the triangle.
The inverse trigonometric functions
help to find the value of an unknown angle of a right triangle when length of two sides are given.
Consider 
Put 

So, point
satisfies the function 
Therefore, graph of function
passes through
