Answer:

The coordinates of N are (-1,-6)

Step-by-step explanation:

M is the midpoint of AN

A(-7,4) and M(-4,-1)

The distance AM is given by (-4--7,-1 - 4) = (3,-5)

Since AM = MN;

N = M(-4,-1) + (3,-5)

N = (-4 + 3,-1 + -5)

This gives the coordinates of N to be;

N(-1,-6)

Write an equation to represent the number of pages Jesse has read. Using x, the number of days Amir has been reading, write an e

katrin [286]

Question:

Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.

How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?

Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.

Answer:

It will take 6 days

Step-by-step explanation:

For Jesse:

$Rate = 30\ pages/day$

This implies that Jesse will cover 30y in y days

For Amir:

$Rate = 35\ pages/day$

This implies that Amir will cover 35x in x days

Because Amir starts a day later,

$y = x + 1$

So, we have the following equations:

$Jesse = 30y$

$Amir= 35x$

$y = x + 1$

To get the number of days when they read the same number of pages, we have:

$Jesse = Amir$

Substitute values for Jesse and Amir

$30y = 35x$

Substitute x + 1 for y

$30(x+1) = 35x$

Open bracket

$30x+30 = 35x$

Collect Like Terms

$30 = 35x-30x$

$30 = 5x$

Solve for x

$\frac{30}{5} = \frac{5x}{5}$

$\frac{30}{5} = x$

$6 = x$

$x = 6$

What is the value of the logarithm?

sweet-ann [11.9K]

Answer:

3.9512

Step-by-step explanation:

You can find the answer by simply putting the value of natural log in a calculator.

ln (52) = 3.951243719

ln (52) = 3.9512 (rounding to nearest 10000th)

Which is the value of natural log of 52 rounded to the nearest ten thousandth

__________________________________________________________

<em>Note: To round off, we will see the number after the 10000th is greater than 5 or not, since the number is 4 and it is less than 5 so we will not raise the 10000th number which is 2</em>
