Answer:

B) L(x) = -x + 2

Step-by-step explanation:

To find the tangent at (1,1), we differentiate x² - ln(x/y) = 1 with resect to x.

So, x² - ln(x/y) = 1  

x² - (lnx - lny) = 1

x² - lnx + lny = 1

differentiating both sides with respect to x, we have

d{x² - lnx + lny]/dx = d1/dx

dx²/dx - dlnx/dx + dlny]/dx = d1/dx

2x - 1/x + 1/y(dy/dx) = 0

1/y(dy/dx) = 1/x - 2x

dy/dx = y(1/x - 2x)

dy/dx evaluated at (1,1) is

dy/dx = y(1/x - 2x)

= (1)(1/1 - 2(1))

= 1 - 2

= -1

This is the gradient of the tangent line.

To find the equation of the tangent line, we use (y - y')/(x - x') = m where y' = 1, x' = 1 and m = gradient of line = dy/dx = - 1

(y - y')/(x - x') = m

(y - y')/(x - x') = dy/dx

(y - 1)/(x - 1) = -1

cross-multiplying,

y - 1 = -1(x - 1)

expanding the bracket, we have

y - 1 = -x + 1

adding + 1 to both sides, we have

y -1 + 1 = -x + 1 + 1

y = -x + 2

So, L(x) = -x + 2

Answer:

IRR = 31.93%

Step-by-step explanation:

Depreciation = 570,000/5 = 114,000

Calculation of Operating cash flow

Operating income = 270000 - 114000 = 156,000

Tax = 156,000 * 35% = 54,600

Operating cash flow = Operating income + Depreciation - Tax = 156,000 + 114,000 - 54,600 = 215,400

Calculation of initial investment

CF0 = Initial investment - Working capital = 570,000 - 73,000 = 497,000

Calculation of the last year cash flow

CF5 = OCF + After tax salvage - Net working capital = 215,400 + 37,000 - 73,000 = 180,100

Calculation of IRR

IRR for the project = IRR(Cashflow from year0, 1, 2,3,4,5) "as attached below picture below"

IRR for the project = 31.93%

Answer:

x + (12x16) = 274

Step-by-step explanation:

each package = 12

16 packages

16x12= 192

x + 192 = 274

274-192=82

x =  82

The function to model the size of Sabrina’s collection is x + (12× 16) = 274.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Total cards =  cards

Each package = 12

let the size of Sabrina collection be x

Then, x + (12× 16) = 274

x + 192 = 274

x =  274- 192

x= 82

Hence, the function to model the size of Sabrina’s collection is x + (12× 16) = 274.

Answer:

slope equals 3

Answer:

1 1/2

Step-by-step explanation:

Given the improper fraction 3÷2, this can also be written as 3/2.

Writing as a mixed fraction means writing as a combination of a whole number and fraction e.g a b/c

a is the whole number

b/c is the fraction

3/2 = 1.5

1.5 = 1 + 0.5

1+0.5 = 1 + 5/10

3/2 = 1 + 1/2

Hence 3÷2 expressed as mixed fraction is 1 1/2

The mixed number representation of 3 ÷ 2 is 1 1/2.

To write the quotient of 3 ÷ 2 as a mixed number, we use the whole number part of the quotient as the whole number part of the mixed number.

We write the remainder (1) in the numerator of the fraction, and the divisor (2) in the denominator of the fraction.

As, the whole number part of the quotient is the number of times the divisor (2) can be divided into the dividend (3) evenly.

In this case, 2 can go into 3 once, with a remainder of 1.

To express this as a mixed number, we write 1 as the whole number part, and the remainder (1) as the numerator of the fraction. The divisor (2) is written in the denominator of the fraction.

Therefore, the mixed number representation of 3 ÷ 2 is 1 1/2.

Answer:

Step-by-step explanation:

From the given information:

The null and the alternative hypothesis can be well written as:

[tex]H_o:P=0.6[/tex]

[tex]H_1:P>0.6[/tex]

Given that:

n = 200

x = 135

Alpha ∝ = 0.05 level of significance

Then;

⇒ [tex]n \times p\times (1-P)[/tex]

= 200 × 0.6 × (1 -0.6)

= 200 × 0.6 × 0.4

= 48 ≥ 10

The sample proportion [tex]\hat P = \dfrac{x}{n}[/tex]

[tex]= \dfrac{135}{200}[/tex]

= 0.675

The test statistics [tex]Z = \dfrac{\hat P - P}{\sqrt{ \dfrac{P(1-P)}{n} }}[/tex]

[tex]Z = \dfrac{0.675 - 0.6}{\sqrt{ \dfrac{0.6 \times 0.4}{200} }}[/tex]

[tex]Z = \dfrac{0.075}{\sqrt{ \dfrac{0.24}{200} }}[/tex]

Z = 2.165

The P-value = P(Z > 2.165)

= 1 - P(Z < 2.165)

From the z tables

= 1 - 0.9848

= 0.0152

Reject the null hypothesis since P-Value is lesser than alpha. ( i.e. 0.0152 < 0.05).

Thus, there is enough evidence to conclude that the value of the population proportion is greater than 0.6

c₁₆ - a₁₆ = 12 - 10 = 2₁₆

7 < c = 12 in base 16, so borrow 1 from the next place value:

17₁₆ - c₁₆ = 23 - 12 = 11 = b₁₆

In the next place, we replace 5 with 4, but 4 < 6, so borrow 1 from the next place value again:

14₁₆ - 6₁₆ = 20 - 6 = 14 = e₁₆

Replace d with c, so that

c₁₆ - 7₁₆ = 12 - 7 = 5₁₆

and this gives

Answer:

A generic exponential function can be written as:

f(x) = A*e^(b*x)

Where A and b are real numbers, that we need to find.

We know that the points (3, 6) and (7, 18) are solutions to the equation, then we have that:

A*e^(b*3) = 6

A*e^(b*7) = 18

This is a system of equations, to solve this we can take the quotient between the two equations, so we remove the variable A.

(A*e^(b*7))/(A*e^(b*3)) = 18/6

e^(b*7)/e^(b*3) = 3

e^(b*7 - b*3) = 3

e^(4*b) = 3

Now we can apply the Ln(x) to both sides, because:

Ln(e^y) = y

then:

Ln(e^(4*b)) = Ln(3)

4*b = Ln(3)

b = Ln(3)/4

Then we have:

f(x) = A*e^(Ln(3)/4*x)

And we can use one of the equations to find the value of A. for example:

6 = A*e^(Ln(3)/4*3)

6/e^(Ln(3)/4*3) = 2.632

Then the exponential function is:

f(x) = 2.632*e^(Ln(3)/4*x)

Then we have that:

f(20) = 2.632*e^(Ln(3)/4*20) = 639.576

Rounding to the next integer, we have:

f(20) = 640

An exponential function can represent growth or decay.

The value of f(20) is 673

An exponential function is represented as:

[tex]y = ab^x[/tex]

At point (3,6), we have:

[tex]6 = ab^3[/tex]

At point (7,18), we have:

[tex]18 = ab^7[/tex]

Divide both equations

[tex]\frac{18}{6}= \frac{ab^7}{ab^3}[/tex]

[tex]3= b^4[/tex]

Take 4th roots of both sides

[tex]\sqrt[4]{3}= b[/tex]

Rewrite as:

[tex]b = \sqrt[4]{3}[/tex]

[tex]b = 1.32[/tex]

Substitute 1.32 for b in [tex]6 = ab^3[/tex]

[tex]a(1.32)^3 = 6[/tex]

[tex]2.30a = 6[/tex]

Divide both sides by 2.3

[tex]a = 2.61[/tex]

So, the function is:

[tex]y =2.61(1.32)^x[/tex]

When x = 20, we have:

[tex]y =2.61(1.32)^{20[/tex]

[tex]y =673[/tex]

Rewrite as:

[tex]f(20)=673[/tex]

Hence, the value of f(20) is 673
