log(x) - log (3) = 8 => x = 299916251.899, by properties of logarithm.

Now,

log (x) - log (3) = 8

=> log (x) = 8 + log (3) = 8 + 0.477

=> log (x) = 8.477

Since, generally the base of log is 10, raising them to 10.

=> [tex]10^{log_{10}x} = 10^{8.477}[/tex]

=> x = 299916251.899 (as  [tex]a^{log_a(x)} = x[/tex])

Hence, log(x) - log (3) = 8 => x = 299916251.899, by properties of logarithm.

Answer:

x = 30

Step-by-step explanation:

To find the x intercept, you need to substitute [tex]y = 0[/tex], as all points on the x axis's y-coordinate is 0.

[tex]0 = 30000 - 1000x\\ \\ \to 0 + 1000x = 30000 \cancel{- 1000x + 1000x} \\\\ \to 1000x = 30000 \\ \\\to \frac{1000x}{1000} = \frac{30000}{1000} \\ \\\to x = 30[/tex]

Option C: Samantha is correct because when using x=2, the resulting values in both expressions are equal.

Consider, 4x + 2

When x = 2,

=> 4x + 2 = 4*2 + 2

=> 10

Now consider, x + 17 + 3x - 15

When x = 2,

=> 2 + 17 + 3*2 - 15

=> 10

Therefore, Samantha is correct as both expressions equal 10 when x=2.

In other words, if we consider, x + 17 + 3x - 15

=> x + 17 + 3x - 15

=> x(1+3) + 17 - 15

=> 4x + 2

This shows that for any value of x, the expression x + 17 + 3x - 15, simplifies to 4x + 2.

Therefore, both the expressions, 4x + 2 and x + 17 + 3x - 15, are equal.

Answer:

Step-by-step explanation: 14 minutes

Expression as a single natural logarithm is ln 64/64 = ln 1.

ln 1 is the converted from 2 ln 8-3 ln 4 to a single natural logarithm.

We need to convert 2 ln 8-3 ln 4 as a single natural logarithm.

First apply power property

⇒ ln 8² - ln 4³

⇒ ln 64 - ln 64

Now, applying quotient property

⇒ ln 64/64 = ln 1

Here, we finally converted 2 ln 8-3 ln 4 to a single natural logarithm ln 1.

The inverse of an exponential function, the natural log is the logarithm to the base of the number e. Natural logarithms are unique varieties of logarithms that are employed in the treatment of time and growth-related issues.

The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).

Answer: 7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)

                              J(-3, 1) = J'(4, 0)

                              F(-2, 3) = F'(5, 2)

                              N(-2, 0) = N'(5, -1)

Step-by-step explanation:

If you want to translate a point 7 units right, you'll need to add 7 to its x-coordinate. If you want to translate a point 1 unit down, you'll need to subtract 1 from its y-coordinate. Do both of these things to perform a translation 7 units right and 1 unit down.

So, we can write,

            7 units right means add the +7

             1 unit down means subtract the -1

Then,

                  J(-3, 1) = J'(-3 + 7, 1 - 1)

                  J(-3, 1) = J'(4, 0)

                  F(-2, 3) = F'(-2 + 7, 3 - 1)

                  F(-2, 3) = F'(5, 2)

                  N(-2, 0) = N'(-2 + 7, 0 - 1)

                  N(-2, 0) = N'(5, -1)

Therefore,

These points to make sure they have shifted 7 units right and 1 unit down.

   7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)

                              J(-3, 1) = J'(4, 0)

                              F(-2, 3) = F'(5, 2)

                              N(-2, 0) = N'(5, -1)

The intercepts and the standard form of each polynomial are listed below:

In this case we need to find the intercepts of each quadratic equation and transform each quadratic equation into standard form. The x-intercept correspond with each of the roots of the polynomial and the y-intercept is found by evaluating the expression at x = 0.

Now we proceed to find each element:

Case 1

x-Intercept

x = - 4 or x = 6

Standard form

f(x) = (x + 4) · (x - 6)

f(x) = x² - 2 · x - 24

y-Intercept

f(0) = - 24

Case 2

x-Intercept

x = 1 / 4 or x = 3

Standard form

f(x) = (2 · x - 4) · (x - 3)

f(x) = 2 · (x - 2) · (x - 3)

f(x) = 2 · (x² - 5 · x + 6)

The standard form will be

Polynomials in standard form can also be referred to as the standard form of a polynomial which means writing a polynomial in the descending order of the power of the variable. To write a polynomial in a standard form, the degree of the polynomial is important as in the standard form of a polynomial, the terms are written in decreasing order of the power of x. The standard form of polynomial is given by, f(x) = anxn + an-1xn-1 + an-2xn-2 + ... + a1x + a0, where x is the variable and ai are coefficients.

A mathematical expression of one or more algebraic terms in which the variables involved have only non-negative integer powers is called a polynomial. The terms have variables, constants, and exponents. The standard form polynomial of degree 'n' is

aₙxⁿ+aₙ₋₁xⁿ⁻¹+aₙ₋₂xⁿ⁻²+.......

Answer:

C.

Step-by-step explanation:

C describes theta moving +5 units. In math, negative goes left, negative goes left. However, since there are no negative values involved, we can assume that theta will move 5 units to the left in terms of absolute value, which excludes the need for the negative to be moved left. Therefore, the answer is C due to this change.

The equation of the translated graph from the parent function is g(x) = |x + 2| + 1

The parent function is given as

f(x)= |x|

From the graph, we can see that the parent function f(x) is translated as follows:

The above sequence of translation is represented as

(x, y) = (x + 2, y + 1)

So, we have

g(x) = |x + 2| + 1

Answer:

50 meters

Step-by-step explanation:

Width is x

So length will be x + 20

Perimeter = 2 (W + L) = 2 (x + x + 20) = 2 (2x + 20) = 4x + 40

so 4x + 40 = 160

4x = 120

so length = x + 20 = 30 + 20 = 50

Given that Angles A and B are complementary to each other, the numerical value of x is 15.

Complementary angles are angles that sum up to 90 degrees.

Given the data in the question;

Since Angles A and B are complementary to each other, the sum of angle A and B is 90 degrees.

Measure of angle A + Measure of angle B = 90°

Plug in the given values and solve for x.

41 + (2x + 19) = 90

41 + 2x + 19 = 90

2x + 60 = 90

2x = 90 - 60

2x = 30

The domain and range of the function f(x) is [1, ∞) and (0, ∞) and g(x) is (0,∞) and [-1, ∞).

Domain of function f(x) :

So, we get that:

x ≥ 1

Range = (0, ∞) as square of a number is always positive.

Domain of function g(x):
