Answer:
√13
Yes you are right
Step-by-step explanation:
The law of cos again
BC^2 = 18 + 25 - 2 * 3√2 * 5 cos(45 degrees)
= 13
==>
BC = √13
Answer:
Step-by-step explanation:
In y = mx + b form, the slope is in the m position and the y intercept is in the b position.
5x + 2y = 8
2y = -5x + 8
y = -5/2x + 8.....slope (m) is -5/2
3x - 7y = 10
-7y = -3x + 10
y = 3/7x - 10/7.....y int (b) = -10/7
so ur equation with slope(m) of - 5/2 and y int (b) of -10/7 is :
y = -5/2x - 10/7 <== slope intercept form
Half of the circumference:
18.84/2 which would leave you with 9.42 feet.
