Answer:

B C and D are all true.

Step-by-step explanation:

In 3 minutes Thea reads 540 words. In one minute she reads 540/3 = 180 words per minute. That means that she does NOT read as many words per minute as does Elinor who reads 225 words / minute.

So what's the answer?

B is true. You could check this with 1440 / 8 = which also gives 180, so Thea is consistent.

C is true. 2 * 225 = 450. Elinor reads 450 words in 2 minutes.

D is true. You can multiply 60 * 225 and 60 * 180 to confirm that Elinor is going to get through the book faster than Thea.

Simplify (6x^2+11x-3) + (2x^2-17x-4)

Nikitich [7]

Pick out the like terms. 6x^2 (which equals 36x), 11x, 2x^2 (which equals 4x), -17x.

36+11+4= 51, -17= 34x

-3+-4= -7

The simplified expression would be 34x+-7.

(This could be wrong though, I'm sorry if it is ^^)

A particle starts at the point P=(−1,1,3)P=(−1,1,3) and moves along a straight line toward Q=(−4,4,5)Q=(−4,4,5) at a speed of 7

zvonat [6]

Answer: (-1,1,-3) + 7 x t x (3,-2,-8)/ $\sqrt{77} \\$

Step-by-step explanation:

The parametric vector equation for the position of particle is given as:

We have P= (-1,1-3)

Q= (-4,4,5)

So PQ vector= (-1+4,1-3, -3-5)

PQ = (3,-2,-8)

Magnitude of this vector= $\sqrt{(3)^2+(-2)^2+(-8)^2}$

Magnitude= $\sqrt{77} \\$

So unit vector= (3, -2, -8)/ $\sqrt{77} \\$

Now the equation is as:

P + 7 x t x unit vector = (-1,1,-3) + 7 x t x (3,-2,-8)/ $\sqrt{77} \\$
