n first gear, or low gear, an automobile's engine runs about three times as fast as the drive shaft. In second gear, the engine

does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft. Finally, in third, or high gear, the engine runs at the same speed as the drive shaft. Engine speed = 1,850 r.p.m. Transmission in second gear Drive-shaft speed =

Answer:

Consider the following cases

Case 1: In n first gear, an automobile's engine runs about three times as fast as the drive shaft.

So, if Speed of Engine = 1,850 r.p.m

Then Speed of Drive Shaft $=\frac{1850}{3}=616.67$ r.p.m

Case 2 : In second gear, the engine does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft.

So, if Speed of Engine = 1,850 r.p.m

Then Speed of Drive Shaft $=\frac{1850}{1.6}=1156.25$ r.p.m

Case 3: Finally, in third, or high gear, the engine runs at the same speed as the drive shaft.

So, if Speed of Engine = 1,850 r.p.m

Then Speed of Drive Shaft is also equal to 1,850 r.p.m

Identify the equation of a line in slope-intercept form that is perpendicular to y = -1/3 x + 2 and passes through (2, 1)

Airida [17]

Answer:

Step-by-step explanation:

The slope of a line perpendicular to another line is the opposite reciprocal of the slope of the other line, meaning if the slope of the other line is $-\frac{1}{3}$ , then the slope of the line perpendicular is $3$ .

Knowing this, we can start to construct the equation for the line:

$y = mx + b$

$y = 3x + b$

To solve for $b$ , we plug in the coordinates of the point that we know the line runs through, $(2, 1)$ :

$y = 3x + b$

$1 = 3(2) + b$

$1 = 6 + b$

$b = -5$

Therefore, the slope of the line that is perpendicular ot the line provided in the equation is the following:

$y = 3x - 5$

Write an equation that passes through the points (0,-5) and (8,-5)

bezimeni [28]

Answer:

Equation of the line: $y = -5$ .

Step-by-step explanation:

Let $(x_0,\, y_0)$ and $(x_1,\, y_1)$ denote the coordinates of these two points, respectively.

Calculate the slope $m$ of this line:

$\displaystyle m = \frac{y_1 - y_0}{x_1 - x_0} = \frac{(-5) - (-5)}{8 - 0} = 0$ .

Notice that the slope is zero because the two points have the same $y$ -coordinates ( $y_0 = y_1 = -5$ ) even though their $x$ -coordinates are distinct ( $x_0 \ne x_1$ .)

Equation for this line in point-slope form:

$y - y_0 = m\, (x - x_0)$ .

$y - (-5) = 0\, (x - 0)$ .

Rewrite and simplify to obtain the equation of this line in slope-intercept form:

$y = -5$ .

The $x$ -term was eliminated because the slope was zero.
