Answer:

The best estimate would be C. 7 ft

Step-by-step explanation:

This is more of a logical question. When you think about a door, 7 inches is out. 7 yards would be 21 ft and that is unusually tall for a door, as is 70 feet.

If you were to write the equation of this line in the form y=mx+c what is the value of m

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

$m = \frac{dy}{dx}$

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{1 - 0}{0 - 4} \\ m = \frac{1}{ - 4} \\ m = - \frac{1}{4}$

Therefore the value of m is - 1/4

An automobile engineer is revising a design for a conical chamber that was originally specified to be 12 inches long with a circ

icang [17]

The scale factor is 1.5, which means that the revised chamber is larger. The new dimensions are just the old dimensions times 1.5.

The volume of the revise chamber is:

V = (1/3) (PI) [(D/2)^2] (H)

= (1/3) (PI) {[(5.7)(1.5)/2]^2} [(12)(1.5)]

= 344.4874 in3
