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

The function p(x) = −2000x2 + 18000x − 15000 models the monthly profit P of a smoothie company, where x represents the price per
ohaa [14]

Answer:

Step-by-step explanation:

Givem the profit function

p(x) = −2000x2 + 18000x − 15000

We are to generate the price range that will generate a monthly profit of at least $25,000

Substitute into the function we have;

25000 = −2000x2 + 18000x − 15000

Divide through by 1000

25 = -2x²+18x-15

Rearrange

-2x²+18x-15-25 = 0

2x²-18x+40 = 0

Divide through by 2

x²-9x+20 = 0

Factorize

x²-5x-4x+20 = 0

x(x-5)-4(x-5) = 0

x-4 = 0 and x-5 = 0

x = 4 and x = 5

Hence the price range that will generate a monthly profit of at least $25,000 is between $4 and $5 inclusive

you bought your friends a heart shaped pound of chocolate caramels. You anticipate each chocolate was 50 calories. Each chocolat
Wittaler [7]

There was 25.37% error in calculations.

Step-by-step explanation:

Given,

Anticipated calories = Approx value = 50 calories

Actual calories = Exact value = 67 calories

Percent error = \frac{|aprrox\ value-exact\ value|}{exact\ value}*100

Percent error = \frac{|50-67|}{67}*100

Percent error = \frac{|-17|}{67}*100=\frac{17}{67}*100

Percent error = \frac{1700}{67}

Percent error = 25.37%

There was 25.37% error in calculations.
