Answer:
y = -(8/15)x + 289/15
Step-by-step explanation:
Slope of the normal at P:
(15-0)/(8-0)
15/8
Slope of the tangent:
-8/15
y = (-8/15)x + c
15 = (-8/15)(8) + c
c = 15 + 64/15
c = 289/15
y = -(8/15)x + 289/15
Answer:
2035.75 cm/min
Step-by-step explanation:
-Since the two gears are connected by the same chain, they have the same linear velocity.
-Linear velocity is distance covered over time:
![Speed=\frac{Distance}{Time}\\\\=\frac{Circumference}{Time}\\\\=\frac{36\times 3\times\pi\times 6}{1}\\\\=648\pi \ cm/min \ or \ 2035.75 cm/min](https://tex.z-dn.net/?f=Speed%3D%5Cfrac%7BDistance%7D%7BTime%7D%5C%5C%5C%5C%3D%5Cfrac%7BCircumference%7D%7BTime%7D%5C%5C%5C%5C%3D%5Cfrac%7B36%5Ctimes%203%5Ctimes%5Cpi%5Ctimes%206%7D%7B1%7D%5C%5C%5C%5C%3D648%5Cpi%20%5C%20cm%2Fmin%20%5C%20or%20%5C%202035.75%20cm%2Fmin)
Hence, the linear velocity of both gears is 2035.75 cm/min
Answer:
Acute angle
Step-by-step explanation:
Answer:
80%
Step-by-step explanation: Because if 20% of 250 equal 50 then 200 is 80% because adding 4 50 is 200.
Answer:
See below.
Step-by-step explanation:
The solutions (also called zeros and x-intercepts) are the roots of the equation. The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.
If the x-intercepts or roots are x= 1 and x= 7, then the factors are x-1 and x-7.
So the factored form is (x-1)(x-7).
