The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,
L (arc) = (Angle / 360) x 2πr
Substituting the known values,
L (arc) = (40 / 360) x 2π(8 inch) = 16π/9 inch
Thus, the length of the arc is approximately equal to 5.585 inches.
Answer:
No
Step-by-step explanation:
12:15 can be simplified to 4:5
6:14 can be simplified to 3:7
These two are not equivalent to eachother
Answer:
Step-by-step explanation:
Hey! Your answer for this is
7x^2 + 3x^2 = 10x^2
-2x + 15x = 13x
9 - 4 = 5
Hence, 10x^2 + 13x + 5.
Hope this helps!
Answer:
y = (1/3)x - 1
Step-by-step explanation:
The product of the slopes of perpendicular lines is -1. That makes the slopes of perpendicular lines negative reciprocals. Since line p has slope -3, the slope of line t is 1/3. Also, line t passes through point (9, 2).
y = mx + b
m = slope
y = (1/3)x + b
Now we replace x and y with the x- and y-coordinates of the given point, respectively, and we solve for b.
2 = (1/3)(9) + b
2 = 3 + b
b = -1
Now we replace b with -1.
y = (1/3)x - 1
