Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.
Aloiza [94]

Answer:

0.70275

Step-by-step explanation:

Data provided in the question:

4e²ˣ⁻¹ -1 = 5

now solving for 'x'

⇒ 4e²ˣ⁻¹ = 5 + 1

or

⇒ 4e²ˣ⁻¹ = 6

or

⇒ e^{(2x-1)} =\frac{6}{4}

or

⇒ e^{(2x-1)} =\frac{3}{2}

now,

taking natural log both sides, we get

⇒ 2x - 1 = \ln(\frac{3}{2})

also,

we know

⇒ \log(\frac{A}{B}) = \log(A)+\log(B)

thus,

⇒ 2x - 1 = ln(3) - ln(2)

or

⇒ 2x - 1 = 1.0986 - 0.6931

or

⇒ 2x - 1 = 0.4055

or

⇒ 2x = 0.4055 + 1

or

⇒ 2x = 1.4055

or

⇒ x = 0.70275

What is the quotient when 2x^3-1 is divided by x - 1?
andrey2020 [161]

Answer:

Step-by-step explanation:

Use synthetic division:

The coefficients of 2x^3 - 1 are {2, 0, 0, -1}.  Setting up synthetic division, we get:

1    /    2    0    0    -1

                2     2    2

    ---------------------------

          2     2    2     1

Note that the remainder is 1.  The same result would be obtained through long division.

The quotient is 2x^2 + 2x + 2 with a remainder of 1.

Hugh has the choice between investing in a city of heflin bond at 6.45 percent or a surething bond at 10.40 percent. assuming th
netineya [11]

Surething Inc. must give an interest rate of 17.33 percent to generate a 10.40 percent after-tax return and make Hugh indifferent between investing in the two bonds.

To solve for the pretax rate of return, we can use this formula:

<span> After-tax return = Pre-tax return x (1 – Marginal Tax Rate). </span>

10.40% = Pre-tax return x (1 – Marginal Tax Rate);

<span>Pre-tax return = 10.40% / (1 – Marginal Tax Rate) = 17.33%</span>
