Answer:

Step-by-step explanation:

If i is 300 times as much as k, then i=300k.

So we have k(something)=300k -> that something is 300

What is the quotient (x^3+8)/(x+2)

Citrus2011 [14]

Answer:

Step-by-step explanation:

The easiest way to do this is by using synthetic division (I really hope you know what I'm talking about!)

If the factor is x + 2 = 0, then the solution or the root is x = -2. We will put -2 outside the "box" and the coefficients from the terms of the polynomial inside the "box":

-2| 1 0 0 8

Bring down the first number and multiply it by the -2. Put the product up under the first 0 and add:

-2| 1 0 0 8

-2

1 -2

Now multiply the -2 by the -2, put the product up under the next 0 and add:

-2| 1 0 0 8

-2 4

1 -2 4

Now multiply the 4 by the -2, put the product up under the 8 and add:

-2| 1 0 0 8

-2 4 -8

1 -2 4 0

Those bold numbers are the coefficients to the quotient, which is another polynomial, but is one degree less than the one you started with:

x² - 2x + 4 = 0

Since there is no remainder, then x = -2 is a zero of x³ + 8, and (x + 2) is a factor.

There is a whole world of stuff to learn about quadratics!!

The rules for an essay contest say that entries can have 500 words with an absolute deviation of at most 30 words. Write and sol

cupoosta [38]

Answer:

470<x<530

Step-by-step explanation:

Let x be number of acceptable words

|x-500|<300

we write absolute value inequality representing the acceptable number of words, given the fact that absolute deviation is at most 30 words

-30<x-500<30

500-30<x-500+500<30+500

470<x<530.

Help with this question please answer it

Elanso [62]

Answer:

15.5 yards

They will be picked up at an elevation of 15.5 yards

Step-by-step explanation:

Here we are going to make the ski slope of the mountain as the hypotenuse of a right-angled triangle where the top of the slope and bottom of the slope are two ends of the hypotenuse.

We first have to find the height of the top of the mountain with respect to the bottom.

Here we have been given heights with respect to sea level above and below.

Clearly, sum of the distances above and below sea level will be total elevation with respect to the bottom.

h1 - Height of summit above sea level

h2 - Height of bottom below sea level

Hb - Elevation of top w.r.t bottom

Hb = h1 + h2

Hb = $17\frac{3}{4}+13\frac{1}{4}$

Hb = 31 yards

Now, the ski lift is picking them up in the middle of the slope (hypotenuse of the triangle).

By midpoint theorem line segment parallel to base joins the midpoints of the other 2 sides.

Thus the elevation will clearly be half of total elevation.

Height at which they are picked up is Hb/2

Therefore,

They will be picked up at an elevation of 15.5 yards
