Answer:
y = 2x + 10
Step-by-step explanation:
y1 = 4
x1 = -3
slope,m = 2
y - y1 = m(x - x1)
y - 4 = 2(x + 3)
y - 4 = 2x + 6
y = 2x + 10
Answer:
1g - 50 = p(g)
Step-by-step explanation:
Answer:
He would need to work 8 weeks for 2300, 16 for 6400, and 22 for 8800
Step-by-step explanation:
You have to divide 3,200 by 400 since thats how much he makes in a week
that gives you 8
and you do the same for the rest
equation:
money wanted/400=weeks
The radii to the points of tangency in each circle are parallel. Connecting the tangent point of the smaller circle to the corresponding radius of the larger circle creates a right triangle with hypotenuse 16 +4+6 = 26 and leg 16 -6 = 10. These numbers let you find the straight length between wheels as
.. √(26^2 -10^2) = 24
The minor arc of belt around the smaller wheel is 2*arccos(10/26) = 2.35201 radians. Then the major arc of belt around the larger wheel is
.. 2π -2.35201 = 3.93117 . . . radians
Of course, the length of each arc is the product of radian measure and radius. Then the total belt length is
.. (16 cm)(3.93117 radians) +(6 cm)*(2.35201 radians) +2*(24 cm) = 125 cm
When two triangles are congruent, everything in them is congruent (same). So, the angle bisector of one triangle is congruent to the corresponding angle bisector of the other triangle.
