Function is a line points (3,2), (5,8), and (8,y) what is y
SashulF [63]
Y = mx + b

(3;\ 2)\to x_1=3;\ y_1=2\\\\(5;\ 8)\to x_2=5;\ y_2=8\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\to m=\dfrac{8-2}{5-3}=\dfrac{6}{2}=3

Therefore we have: y = 3x + b.

Put the coordinates of the point (3; 2) to the equation of the line:

2 = 3\cdot3+b\\2=9+b\ \ \ |-9\\b=-7

Therefore we have: y = 3x - 7

Substitute the coordinates of the point (8; y) to the equation of the line:

y = 3\cdot8-7=24-7=17

Answer: y = 17.

A 240hp automobile engine delivers 195hp to the drive wheels, what is the effciency of the transmission and drive mechanism?
sweet-ann [11.9K]

Answer:

81.25%

Step-by-step explanation:

Given that :

Engine power = 240 hp

Power delivered to drive wheel = 195 hp

Efficiency = (power delivered to drive wheel / Engine power) * 100%

Efficiency = (195 / 240) * 100%

Efficiency = 0.8125 * 100%

Efficiency = 81.25%

The efficiency of transmission and drive mechanism is 81.25%
