Train A leaves the station traveling east at 55 mph, while train B leaves the station 45 minutes later traveling west at 70 mph.

Choose the equation below that represents the distance in miles between the two trains, D, as a function of T, the time in hours after train B has departed.
A.
D = 125T
B.
D = 125T + 41.25
C.
D = 125T - 41.25

Answer: b)  D=125T+41.25

Step-by-step explanation:

Given,

speed of train A travelling east = 55 mph

speed of train B travelling west = 70 mph

time train A travelled while train B was at rest = 45 min or (\frac{3}{4})hr

so, Distance travelled by train A while train B was at rest = 55(\frac{3}{4} ) miles\\

                                                                                               = 41.25 miles

Now, after 'T' hour both the train will travel;

train A = 55T

train B = 70T

hence, the distance (D) between two train in miles will be;

⇒ D = 41.25 + 55T + 70T

⇒ D = 125T + 41.25

Let f(x)=g(x)h(x), g(10)=-4, h(10)=560, g'(10)=0, and h'(10)=35. find f'(10)
Ulleksa [173]
This question has extraneous info to trick you.
f(x) = g(x)h(x) ⇒ f'(x) = g'(x)h'(x) . Letting x = 10, we get f'(10) = g'(10)h'(10). then just plug in the values provided. g(10) and h(10) are there to throw you off, just use g'(10) and h'(10).
So f'(10), pronounced "eff prime of ten", = 0 * 35 = 0.

If the question were asking for f(10) instead of f'(10) then you would use g(10) and h(10), ⇒-4*560=90.

A line passes through the point (4, -6) and has a slope of 3/2 . Write an equation in slope-intercept form for this line.
tatyana61 [14]

A slope intercept form: y = mx + b where m = slope and b = y -intercept

A slope of 3/2 is given

So y = 3/2 x + b

To find b:

b = y - mx

A line passes through the point (4, -6)

b = -6 - (3/2)(4)

b = -6 - 6

b = - 12

Answer

Equation in  slope intercept form:  y = 3/2 x - 12

Correct Option is D.  Lines 72-75 ("Consider . . . happiness")

In lines 72-75, Wollstonecraft provides evidence that society’s leaders grant freedoms that privilege men. She argues that while society’s leaders believe they “are acting in the manner best calculated to promote [women’s] happiness,” their decisions don’t allow women to “contend for their freedom.”

Choices A, B, and C do not provide the best evidence that society’s leaders grant freedoms that privilege men over women.

<h3>The lines from passage are - </h3>

Consider—I address you as a legislator—

whether, when men contend for their freedom, and

to be allowed to judge for themselves respecting their

own happiness

Previous Question is :

"In Passage 2, the author claims that freedoms granted by society's leaders have:"

<h3>This question is based on paragraph from Mary Wollstonecraft, A Vindication of the Rights of Woman. Originally published in 1792, which is given below -</h3>

Passage 2 -

"Contending for the rights of woman, my main argument is built on this simple principle, that if she be not prepared by education to become the companion of man, she will stop the progress of 45 knowledge and virtue; for truth must be common to all, or it will be inefficacious with respect to its influence on general practice.
