This is because “trig” solves for the missing angles in a right angled triangle and does not solve for the sides of a right angle triangle.
Hope this helps :)
Y = 9x^2 + 5
Use the change rule:
dy / dt = [dy / dx] * [dx / dt]
dy / dx = 18x
and dx / dt = constant = 2 cm / s
Then dy / dt = [18 x] * 2 = 2*18x = 36x
<span>(a) x = -1
dy/dt = 36(-1) = - 36 cm/sec
(b) x = 0
dy/dt = 36(0) = 0 cm/sec
(c) x = 3
dy/dt =36(3) = 108 cm/sec</span>
Answer:
15 weeks
Step-by-step explanation:
15 times 20 = 300
300+60=360
Answer:
59°
Step-by-step explanation:
First we find the value of remembering that the angle that is formed in a straight line (in the diameter of the circle) is 180 °, so the sum :
must be equal to 180°:
and we add the two terms with w:
we move the +4 in the left as a -4 to the right side:
and next we divide by 16:
And now that we know the value of , we can find the measure of the arc YZ:
substituting
The measure of YZ is 59°
