Answer:
Step-by-step explanation:
Hi there!
Slope-intercept form: where is the slope and is the y-intercept (the value of y when x is 0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two given points are and
Plug in the given points (15,2.2) and (5,1.6):
Therefore, the slope of the line is . Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
Plug in a given point and solve for b:
Therefore, the y-intercept is . Plug this back into :
I hope this helps!
The answer to the question is a
I think that the answer is A.
Answer:
Circumference is 12.56
Area is 6.28
Step-by-step explanation:
4×3.14=12.56
2×3.14=6.28
If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.
