A train traveled 1/5 of the distance between two cities in 3/4 of an hour. At this rate, what fraction of the distance between t

lana66690 [7]

Answer:

1/5x=3/4 hour

so since 5 times 1/5=1 then

find x

multiply both sides by 5

x=15/4 hour=3 and 3/4 hour=3 hour and 45 mins

Graph g is a translation of the graph of y= sin x (dashed line).a) write down the equation of g b) write down the coordinates of

labwork [276]

Answer:

<em>b) The coordinates of P are</em>

<em /> $\displaystyle \left( \frac{3\pi}{2},1\right)$

Step-by-step explanation:

<u>Translation</u>

The dashed line shows the graph of the function

$y = \sin x$

This function has a maximum value of 1, a minimum value of -1, and a center value of 0.

Graph G shows the same function but translated by 2 units up, thus the equation of G is:

$\boxed{G(x)= \sin x + 2}$

b) The coordinates of P correspond to the value of

$x = \frac{3\pi}{2}$

The value of G is

$\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2$

Since

$\sin \frac{3\pi}{2}=-1$

$\displaystyle G(\frac{3\pi}{2})= -1+ 2=1$

The coordinates of P are

$\displaystyle \left( \frac{3\pi}{2},1\right)$

What is the area of the shaded region?

jolli1 [7]

Hello!

<h2>Answer:</h2><h2 />

$\boxed{ \bf The~area~of~the~shaded~region~is~B.~24 mm^2}$

______________________________________________________

<h2>Explanation:</h2>

To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.

Outer:

A = $\frac{1}{2}$ bh

A = $\frac{1}{2}$ (12 · 5)

A = $\frac{1}{2}$ (60)

A = 30 mm²

Inner:

A = $\frac{1}{2}$ bh

A = $\frac{1}{2}$ (4 · 3)

A = $\frac{1}{2}$ (12)

A = 6

30 - 6 = 24
