Step-by-step explanation:

Step 1: Define

Identify given.

[tex]\displaystyle f(x) = 3.55x - 4[/tex]

[tex]\displaystyle x = \{ 17, 21, 24, 34 \}[/tex]

Step 2: Find Profit

To find the profit the store makes each day, we input the number of customers that visited the store each day into our given function:

For the day that had 17 customers:

[tex]\displaystyle\begin{aligned}f(17) & = 3.55(17) - 4 \\& = 60.35 - 4 \\& = \boxed{56.35} \\\end{aligned}[/tex]

∴ the butcher store made $56.35 when 17 customers visited the store.

For the day that had 21 customers:

[tex]\displaystyle\begin{aligned}f(21) & = 3.55(21) - 4 \\& = 74.55 - 4 \\& = \boxed{70.55} \\\end{aligned}[/tex]

∴ the butcher store made $70.55 when 21 customers visited the store.

For the day that had 24 customers:

[tex]\displaystyle\begin{aligned}f(24) & = 3.55(24) - 4 \\& = 85.2 - 4 \\& = \boxed{81.2} \\\end{aligned}[/tex]

∴ the butcher store made $81.20 when 24 customers visited the store.

For the day that had 34 customers:

[tex]\displaystyle\begin{aligned}f(34) & = 3.55(34) - 4 \\& = 120.7 - 4 \\& = \boxed{116.7} \\\end{aligned}[/tex]

∴ the butcher store made $116.70 when 34 customers visited the store.

The exponential function is P = 5.63(1.0145)ⁿ. And the population of the city in 2018 is 6.1379 million, the number of the years when the population of the city is 10 million is 40 years, and the doubling time will be 49 years.

The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.

In​ 2012, the population of a city was 5.63 million. The exponential growth rate was 1.45​% per year.

Then the exponential function will be given as

P = 5.63 (1.0145)ⁿ

Where P is the population (in million) and n is the number of years.

Then the population of the city in 2018 will be

n = 2018 - 2012 = 6

Then we have

P = 5.63 (1.0145)⁶

P = 5.63 x 1.0902

P = 6.1379 million

The number of the years when the population of the city is 10 million.

    10 = 5.63 x (1.0145)ⁿ

1.776 = (1.0145)ⁿ

Taking log both sides, then we have

log 1.776 = n x log 1.0145

            n = 39.90

            n ≅ 40 years

Then the doubling time will be

2 = (1.0145)ⁿ

Taking log on both sides, then we have

log 2 = n x log1.0145

      n = 48.1489

      n ≅ 49 years

Step-by-step explanation:

you are "hiding" some more information (like how much they made together).

without that we cannot calculate the actual values.

all I can do is set up the equations expressing the given relations between the parts of the total :

a = amount Alberto made

b = amount Benjamin made

c = amount Carlota made

b = 3×a

c = 2×b = 2× 3×a = 6×a

that's it.

your see ? now we need something that "ties" all 3 together, an equation of all 3 variables, where we can use the first 2 equations (by substitution) and then solve for the remaining third variable.

and that is missing.

if it is something like "together they made x", then we would have

a + b + c = x

a + 3a + 6a = x

10a = x

a = x/10

b and c we get then from the first 2 equations by simply using the calculated value of a :

b = 3×(x/10) = 3x/10

c = 6×(x/10) = 6x/10 = 3x/5

5 is an rational number, not an irrational number.

The probability that exactly 1 doesn't grow will be 0.07

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15

Using the Bernoulli approximation:

P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵

P(n=1)=9x0.15¹.⁵x0.8⁸.⁵

P(n=1)=0.07

Hence the probability that exactly 1 doesn't grow will be 0.07

Formula for finding the 6 trigonometry functions

Finding opposite and adjacent angles

Hope this helps!

Step-by-step explanation:

The six trig functions are

[tex] \sin( \alpha ) = \frac{y}{r} [/tex]

[tex] \cos( \alpha ) = \frac{x}{r} [/tex]

[tex] \tan( \alpha ) = \frac{y}{x} [/tex]

[tex] \csc( \alpha ) = \frac{r}{y} [/tex]

[tex] \sec( \alpha ) = \frac{r}{x} [/tex]

[tex] \cot( \alpha ) = \frac{x}{y} [/tex]

Where

[tex]r = \sqrt{ {x}^{2} + {y}^{2} } [/tex]

[tex]r = \sqrt{ - 2 {}^{2} + {6}^{2} } [/tex]

[tex]r = \sqrt{40} [/tex]

[tex]r = 2 \sqrt{10} [/tex]

So we just plug in -2 for x, 6 for y, and our r value into these functions.

[tex] \sin( \alpha ) = \frac{6}{2 \sqrt{10} } = \frac{3}{ \sqrt{10} } = \frac{3 \sqrt{10} }{10} [/tex]

[tex] \cos( \alpha ) = \frac{ - 2}{2 \sqrt{10} } = \frac{ - 1}{ \sqrt{10} } = \frac{ - \sqrt{10} }{10} [/tex]

[tex] \tan( \alpha ) = \frac{6}{ - 2} = - 3[/tex]

Csc is the reciprocal of sine.

[tex] \csc( \alpha ) = \frac{ \sqrt{10} }{3} [/tex]

Sec is the reciprocal of cosine

[tex] \sec( \alpha ) = - \sqrt{10} [/tex]

Cot is the reciprocal of tan

[tex] \cot( \alpha ) = - \frac{1}{3} [/tex]

The function f(x) =  x² + 12x is a quadratic function, and the vertex of the function is (-6,-36)

The equation of the function is given as:

f(x) =  x² + 12x

Differentiate the function

f'(x) = 2x + 12

Set the function to 0

2x + 12 = 0

Add -12 to both sides

2x = -12

Divide both sides by 2

x = -6

Set x = -6 in the function f(x)

f(-6) =  (-6)² + 12(-6)

Evaluate

f(-6) =  -36

The value of d at the point of equilibrium, to the nearest whole number is 54

The equations are given as:

[tex]d = \frac{-5}{9}p + 94[/tex]

[tex]s = 3p - 160[/tex]

At the point of equilibrium, d = s.

So, we have:

[tex]\frac{-5}{9}p + 94 = 3p - 160[/tex]

Multiply through by 9

-5p + 846 = 27p - 1440

Collect like terms

27p + 5p = 1440 + 846

Evaluate the sum

32p = 2286

Divide through by 32

p = 71.4375

Substitute p = 71.4375 in [tex]d = \frac{-5}{9}p + 94[/tex]

[tex]d = \frac{-5}{9} * 71.4375 + 94[/tex]
