Solve the exponential equation. Use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution.

Answers

Answer 1

Answer:

x = 3.58

Step-by-step explanation:

[tex]e^{4x - 5}[/tex] - 7 = 11243[tex]e^{4x - 5}[/tex] = 11250ln [tex]e^{4x - 5}[/tex] = ln 112504x - 5 = ln 112504x - 5 = 9.33 (rounded)4x = 14.33x = 14.33 / 4x = 3.58 (rounded)
Answer 2

Answer:

x = 3.58 (2 d.p.)

Step-by-step explanation:

Given equation:

[tex]e^{4x-5}-7=11243[/tex]

Add 7 to both sides:

[tex]\implies e^{4x-5}-7+7=11243+7[/tex]

[tex]\implies e^{4x-5}=11250[/tex]

Take natural logs of both sides:

[tex]\implies \ln e^{4x-5}=\ln 11250[/tex]

[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\implies (4x-5)\ln e=\ln 11250[/tex]

As ln(e) = 1:

[tex]\implies 4x-5=\ln 11250[/tex]

Add 5 to both sides:

[tex]\implies 4x-5+5=\ln(11250)+5[/tex]

[tex]\implies 4x=\ln(11250)+5[/tex]

Divide both sides by 4:

[tex]\implies \dfrac{4x}{4}=\dfrac{\ln(11250)+5}{4}[/tex]

[tex]\implies x=\dfrac{\ln(11250)+5}{4}[/tex]

Using a calculator:

[tex]\implies x=3.582030852...[/tex]

Therefore:

[tex]\implies x=3.58\:\: \sf (2 \: d.p.)[/tex]

Triangle 1 has known angles of 36° and 64º.
Triangle 2 has known angles of 64º and xº.
Select all the values of x that would make two triangles similar to each other

Answers

Answer:

so the three sides of same triangle have 36°,64° or 64°

we know the total sum of angles of triangle is 180 then

here to find x

so if we add all the 3 triangle and - (subtract) it with 180° = remaining side

now 36°+64°+64°= 164

now. x= 180-164= 16°

Shannon is purchasing a government bond with a par value of $800 and a price quote of 101.524%. What is the price of the bond?

Answers

Answer: $812.192

Step-by-step explanation:

The price of the bond will be gotten by multiplying the par value by the price quote. This will be:

Price of bond = Par value × Price quote

Price of bond = $800 × 101.524%

Price of bond = $800 × 1.01524

Price of bond = $812.192

Therefore, the price of the bond is $812.192.

All the equation of lines that are parallel to the given line are,

10y = 6x + 12

12x - 20y = 24

3x - 5y= 1

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Equation of parallel line is,

⇒ 3x - 5y = 8

Slope of parallel lines are,

⇒ m = 3/5

Now, We know that;

Slope of parallel lines are same ton each other.

For equation 1;

5x - 3y = 1

3y = 5x - 1

y = 5/3x - 1

dy/dx = 5/3

For equation 2;

9x - 10y = 16

10y = 9x - 16

y = 3/5x - 1

dy/dx = 3/5

For equation 3;

10y = 6x + 12

y = 6/10x + 12

dy/dx = 6/10 = 3/5

For equation 4;

12x - 20y = 24

20y = 12x - 24

y = 12/20x - 1

dy/dx = 12/20 = 3/5

For equation 5;

3x - 5y = 1

5y = 3x - 1

y = 3/5x - 1

dy/dx = 3/5

Thus, All the equation of lines that are parallel to the given line are,

10y = 6x + 12

12x - 20y = 24

3x - 5y= 1
