Answer:

The train travels 0.25 miles per gallon, the slope is 200/50 or 4/1

Step-by-step explanation:

We get this answer by dividing 50 miles by 200 gallons, allowing us to receive the ratio of 0.25 miles per gallon.

The slope is a representation of that ratio, as concluded from the graph

Hope this helps!

Answer:

A.The scale factor is 0.25 ⇒ True

B.The scale factor is 4 ⇒ False

Step-by-step explanation:

See the attached figure.

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

A dilation that creates a smaller image is called a reduction.

As Shown, two right triangles, The first triangle is dilated to form the second triangle.

We can deduce that the second image is a smaller than the first triangle.

The hypotenuse of the first triangle = 4.4

The hypotenuse of the second triangle = 1.1

So, the scale factor = 1.1/4.4 = 11/44 = 1/4 = 0.25

We will check the options:

A.The scale factor is 0.25 ⇒ True

B.The scale factor is 4 ⇒ False

5 x (10^2) is equal to: 450 4,500 45,000 450,000

vazorg [7]

5 x (10^2) =
5 x 100 = 500

I guess you mean:
4,5 x (10^2) =
4,5 x 100 =
450

Which acctually is a valid answer.

A triangle has two constant sides of length 5 feet and 7 feet. The angle between these two sides is increasing at a rate of 0.9

o-na [289]

Answer: $12.74 ft^2/s$

Step-by-step explanation:

Given

Two sides of triangle of sides 5 ft and 7 ft

and angle between them is increasing at a rate of 0.9 radians per second

let $\theta$ is the angle between them thus

Area of triangle when two sides and angle between them is given

$A=\frac{ab\sin C}{2}$

$A=\frac{5\times 7\times \sin \theta }{2}$

Differentiate w.r.t time

$\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\cos theta }{2}\times \frac{\mathrm{d} \theta }{\mathrm{d} t}$

at $\theta =\frac{\pi }{5}$

$\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\times cos(\frac{\pi }{5})}{2}\times 0.9$

$\frac{\mathrm{d} A}{\mathrm{d} t}=12.74 ft^2/s$
