The ellipse 14x2+2x+y2=114x2+2x+y2=1 has its center at the point (b,c)(b,c) where

1 answer:

6 0

18x^2 + 2x + y^2 = 1
==> 18(x^2 + x/9) + y^2 = 1 
==> 18(x^2 + x/9 + 1/324) + y^2 = 1 + 1/18 
==> 18(x + 1/18)^2 + y^2 = 19/18 
==> (x + 1/18)^2/19 + (y - 0)^2/(19/18) = 1. 

By comparing this to the standard form of an ellipse, the center is at (-1/18, 0).

Round off the number 5028.563 to the nearest thousand

konstantin123 [22]

Answer:

5000

Step-by-step explanation:

Because this is to the nearest THOUSAND, you know you are looking for numbers like 1000, 2000, etc. And you see that with 5028.563, it is below 5500, so you do not round up to 6000, so yoyu must round down to 5000.

a language arts test is worth 100 points there is a total of 26 questions . there are spelling word questions that ae worth 2 po

natka813 [3]

10 question of spelling words and 16 questions of vocabulary are present

Solution:

Let "x" be the number of spelling word questions

Let "y" be the number of vocabulary word question

There is a total of 26 questions. Therefore, we get

number of spelling word questions + number of vocabulary word question = 26

x + y = 26 --------- eqn 1

There are spelling word questions that worth 2 points each and vocabulary word question worth 5 points each

The language arts test is worth 100 points

Therefore, we frame a equation as:

number of spelling word questions x 2 + number of vocabulary word question x 5 = 100

$x \times 2 + y \times 5 = 100$

2x + 5y = 100 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 26 - y ------- eqn 3

Substitute eqn 3 in eqn 2

2(26 - y) + 5y = 100

52 - 2y + 5y = 100

3y = 100 - 52

3y = 48

Substitute y = 16 in eqn 3

x = 26 - 16

Thus 10 question of spelling words and 16 questions of vocabulary are present

Dominik [7]

Answer:

Step-by-step explanation:

Let d represent the total number of days that the milk will last.

The total number of cat warriors travelling together is 8. Each cat needs 4 liters of milk per day to maintain good morale. This means that the 8 cat warriors would need

8 × 4 = 32 liters of milk.

Let n represent the total number of liters of milk available. Therefore, the total number of days the milk will last, d would be

d = n/32

Mirri has a supply of 96 liters of milk. Another cat has enough milk to last for 2 days. This means that the amount of milk that the cat has is 4 × 2 = 8 liters. Total amount of milk available would be

96 + 8 = 104 liters

Therefore

d = 104/32 = 3.25 days
