Mathematics

The point (1 - √5, <em>p</em>) lies on the given curve, which means if <em>x</em> = 1 - √5, then <em>y</em> = <em>p</em>. So

<em>p</em> = (10 + 2√5) / (1 - √5)²

and now you just simplify.

(1 - √5)² = 1² - 2√5 + (√5)² = 6 - 2√5

→   <em>p</em> = (10 + 2√5) / (6 - 2√5)

Cancel the common factor of 2 among all the terms:

<em>p</em> = (2•5 + 2√5) / (2•3 - 2√5)

→   <em>p</em> = (5 + √5) / (3 - √5)

Multiply the numerator and denominator by the conjugate of the denominator:

<em>p</em> = (5 + √5) / (3 - √5) • (3 + √5) / (3 + √5)

→   <em>p</em> = ((5 + √5) (3 + √5)) / (3² - (√5)²)

→   <em>p</em> = (15 + 8√5 + (√5)²) / (3² - (√5)²)

→   <em>p</em> = (20 + 8√5) / 4

Cancel the factor of 4:

<em>p</em> = (4•5 + 4•2√5) / 4

→   <em>p</em> = 5 + 2√5

5. Explain how you could use compatible numbers to estimate 245 ÷ 3. Then estimate the quotient.​
sdas [7]

Answer:

8

Step-by-step explanation:

Compatible numbers are defined as the numbers which are very close to the numbers that they are replacing that divides evenly into each other.

In the context, we have to estimate the quotient using the compatible numbers in order to estimate 245 divided by 3.

So, estimating 245 as 240 and 3 as 30.

Here, 240 is very close to 245 and 30 is close to 3. So the quotient is the result when we divide 240 by 30 and it divides evenly into 240.

We first divide the non zero parts of each number i.e. 24 by 3 to get the first part of the estimate.

Then we add on the zero if there were left in the problem to get your estimate.

Therefore,

240 / 30 = 8

So here, the quotient is estimated as 8.

The box plot represents the distribution of the number of points scored by a cross country team at 12 meets. If possible, find t
Reil [10]

The median is the value equivalent to the vertical line as shown. Hence the median point is 34

<h3>What is a median?</h3>

The median is defined as the value at the middle after rearrangement.

From the given boxplot, we have the following

The minimum value is equivalent to the lower position of the whisker = 22

The maximum value is equivalent to the upper position of the whisker = 42

The median is the value vertical line in between the box = 34

The lower quartile (Q1) = starting point of the box = 33

Upper quartile (Q3) = end point of the box = 38

For the boxplot, the median is the value equivalent to the vertical line as shown. Hence the median point is 34
