=2a(3+5b) [ common 2a from both the terms]
Step-by-step explanation:
the area of a track ? for a track we would normally look for the circumference. the area here is more that of an ice rink.
anyway, the area is the sum of the area of the rectangle in the middle and the areas of the 2 half-circles at both ends. since the half-circles are equally large, they are together the area of the full circle.
the length of the rectangle is 92.7 m.
the width of the rectangle is 2 times the radius (the diameter) of the circle = 2×31 = 62 m
the area of the rectangle is
92.7 × 62 = 5,747.4 m²
the area of the circle is
pi × r² = pi × 31² = pi × 961 = 3,019.07054... m²
the total area is then
5,747.4 + 3,019.07054... = 8,766.47054... m²
this is rounded to 1 DP
8,766.5 m²
Answer:
y = -5x + 21
Step-by-step explanation:
The perpendicular slope is opposite of the inverse. The inverse of 1/5 is 5/1, and the opposite of that is -5/1.
So m = -5.
Then use point-slope form:
y + 4 = -5 (x - 5)
If you wish, convert to slope-intercept form:
y + 4 = -5x + 25
y = -5x + 21
