Answer:
Step-by-step explanation:
To find the equation, use the slope-intercept formula:
m is the slope and b is the y-intercept. Now, it'll really help to draw a line through the points, connecting them. If you look at point (0,2), we can see that this is the y-intercept (where a point sits on the y-axis when x=0). You can insert this into the equation by taking the y value:
Now, take any two points to find the slope. To make it easier, I'll use (1,5) and (0,2). Use the slope formula for when you know two points:
Rise over run is the change in the y-axis over the change in the x-axis. Insert values:
Solve:
Since both are negative, the result is a positive:
Insert this into the equation as m, the slope:
Done.
It is the most critical part in algorithm. This is to sort or arrange things or numbers in specific characteristics. This is to make things easier when you will be calculating and you can differentiate the results and your variable being considered in solving the problem.
Answer:
176.7cm^2
Step-by-step explanation:
Area of circle = π ×r^2
π×15^2
and then divide by 4 because it's one quarter of a circle
Answer:
8 feet per second.
Step-by-step explanation:
We have been given that a car is driving away from a crosswalk. The formula 
expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.
We will use average change formula to solve our given problem.
Therefore, the the car's average speed over the given interval of time would be 8 feet per second.
