We can write the values of the function g(- 2) = 1/2 and

g(2) = 128.

An algebraic expression is a combination of terms both constants and variables. For example -

2x + 3y + z

3x + y

Given is the exponential function as -

f(x) = 8(1/4)ˣ

If the function f(x) is reflected across the {y} - axis, then the new function g(x) will be -

g(x) = f(-x)

So, we can write -

g(x) = 8(1/4)⁻ ˣ

Now, we can write -

g(- 2) = f(2) = 1/2

g(2) = f(-2) = 128

Therefore, we can write the values of the function g(- 2) = 1/2 and

g(2) = 128.

Answer:

[tex]15.6 \div 100 = .156[/tex]

Step-by-step explanation:

100 is 10 to the second power. Since you are dividing, move the decimal point in 15.6 two places to the left. So .156 is your answer.

Answer:0.156

Step-by-step explanation:

500 grams is equivalent to approximately 17.637 ounces.

Gram is a metric unit of weight equal to one thousandth of a kilogram.

Ounce is a unit of weight equal to one sixteenth of a pound or 16 drams or 28.349 grams.

Ounce is defined as exactly 28.349523125 grams and is equivalent to one sixteenth of an avoirdupois pound.

To convert 500 grams to ounces,

We can use the conversion factor that 1 ounce is equal to 28.3495 grams.

So, we can write:

500 grams = (500 ÷ 28.3495) ounces

500 grams = 17.637 ounces (rounded to three decimal places)

Therefore, 500 grams is equivalent to approximately 17.637 ounces.

Step-by-step explanation:

Set the equations. Let the variable x denote the amount of months that are needed.

Silver Gym:

In Silver Gym, the membership is a flat fee (constant) of $45, and training sessions are $25 for each session (25x, x denoting the amount of sessions).

Therefore, total cost is:

Total Cost (c) = Training session x Training cost per session + Flat Fee

or

c = 25x + 45

Fit Factor:

In Fit Factor, the membership is a flat fee (constant) of $75, and training sessions are $15 for each session (15x, x denoting the amount of sessions).

Therefore, the total cost is:

Total Cost (c) = Training session x Training cost per session + Flat Fee

or

c = 15x + 75

~

You are trying to solve for the amount of training sessions that have to be bought in which both prices will be the same. Note that both equations are equal to c. Based on the transitive property of equality, if a = b and b = c, then a = c. Therefore:

c = 25x + 45

c = 15x + 75

15x + 75 = c = 25x + 45

15x + 75 = 25x + 45

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 25x and 75 from both sides of the equation:

15x (-25x) + 75 (-75) = 25x (-25x) + 45 (-75)

15x - 25x = 45 - 75

-10x = -30

Next, divide -10 from both sides of the equation:

(-10x)/-10 = (-30)/-10

x = -30/-10 = 3

The slope of the line passing through the points (2, 8) and (2, -4) is undefined.

The slope of the line passing through the points (-7, 8) and (2, 8) is zero.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Substituting the given data points into the slope formula, we have the following;

Slope, m = (-4 - 8)/(2 - 2)

Slope, m = (-12)/0

Slope, m = undefined.

The condition for continuity of a function f(x) at x=a : limf(x) = f(a)

x→a

Before convincing the above condition, we have to examine that the limit is exit or not at x=a. To test the condition for existancy of a limit at x=a of a function

f(x), we have to fulfill the following condition: lim f(x) = lim f(x)

To find the minimum score you would need to be in the top 4%, we need to use the standard normal distribution and the given z-score.

First, we find the z-score corresponding to the top 4% using a standard normal distribution table or a calculator:

z = invNorm(1 - 0.04) = invNorm(0.96) = 1.7507 (rounded to four decimal places)

The minimum score needed to be in the top 4% is the score that corresponds to this z-score in the distribution of exam scores. We can use the formula for standardizing a normal random variable to find this score:

z = (X - μ) / σ

where X is the exam score, μ is the mean of the exam scores, and σ is the standard deviation of the exam scores.

Solving for X, we get:

X = zσ + μ = 1.75076.1 + 76.4 = 87.46
