The slope of the line tangent to the parabola's y-intercepty = [tex](x+2)^2-4[/tex] is 4.

We must first get the parabola's y-intercept in order to determine the slope of the line tangent to it.

We enter x=0 into the equation to obtain the y-intercept:

[tex]y = (x + 2)^2 - 4[/tex]

[tex]y = (0 + 2)^2 - 4[/tex]

y = 4 - 4

y = 0

Hence, the parabola's y-intercept is (0, 0).

The derivative of the parabola's equation must then be determined.

[tex]y = (x + 2)^2 - 4\\y = x^2 + 4x + 4 - 4\\y = x^2 + 4x[/tex]

dy/dx = 2x + 4

By adding x=0 to the derivative, we can now get the slope of the tangent line to the y-intercept:

dy/dx = 2x + 4

dy/dx = 2(0) + 4

dy/dx = 4

Hence, the slope of the line tangent to the parabola's y-intercepty = [tex](x+2)^2-4[/tex] is 4.

David has drawn a total of 177 cm of lines.

We can use the Pythagorean theorem, which tells us that in a right triangle, the square of the length of the hypotenuse (the diagonal line) is equal to the sum of the squares of the lengths of the other two sides (the lines along the long edge and the width).

In this case, the length of the hypotenuse is the distance from the starting corner to the end of the diagonal line, which we can calculate as follows:

d = √(77² + 36²) ≈ 85.99 cm

Therefore, David has drawn a total of 77 cm + 36 cm + 85.99 cm = 198.99 cm of lines. However, we should subtract the length of the starting corner to the end of the first line, which is 77 cm, since it was counted twice (once as part of the diagonal line and once as part of the line along the long edge).

So, the total length of lines that David has drawn is 77 cm + 36 cm + 85.99 cm - 77 cm = 177 cm.

Pythagoras' theorem is a fundamental theorem in mathematics that relates to the sides of a right triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

This can be expressed as:

a² + b² = c²

where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.

Pythagoras' theorem can be used to solve a variety of problems involving right triangles, such as finding the length of a missing side or determining whether a triangle is a right triangle. It is also the basis for the distance formula in two and three-dimensional Euclidean space.

Pythagoras' theorem has applications in many fields, including physics, engineering, and computer graphics, and it is one of the most important and widely used theorems in mathematics.

Answer:

$14,498.1

Step-by-step explanation:

To find the amount Rob will have in 5 years with compound interest, we can use the formula:

A = P (1 + r/n)^(nt)

where:

A = the future value of the investment

P = the principal amount invested

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = $7,869 (the principal amount)

r = 13% or 0.13 (the annual interest rate)

n = 1 (the interest is compounded annually)

t = 5 (the number of years)

Substituting these values into the formula, we get:

A = $7,869 (1 + 0.13/1)^(1*5)

A = $7,869 (1.13)^5

A = $14,964.92

Therefore, to the nearest cent, Rob will have $14,964.92 in 5 years.

John's purchasing power increased by 0.97%.

What is the inflation?

The definition of inflation in the field of economics is "mean increased money supply, but the general public often refer to a sustained increase in the general price level of goods and services in an economy over a period".

If the inflation rate was 3% and John's salary grew 4%, his salary increased more than the rate of inflation. However, his real increase in purchasing power depends on the difference between his salary growth rate and the inflation rate.

To calculate the change in John's purchasing power, we can use the following formula:

Change in purchasing power = (1 + Salary growth rate) / (1 + Inflation rate) - 1

Plugging in the values, we get:

Change in purchasing power = (1 + 0.04) / (1 + 0.03) - 1

Change in purchasing power = 1.01 / 1.03 - 1

Change in purchasing power = 0.0097 or 0.97%

The  single natural logarithm for the expression 4 + ln 2 - ln 4 is ln(2). So, correct option is A.

To express 4 + ln 2 - ln 4 as a single natural logarithm, we can use the properties of logarithms to combine the terms.

First, we can use the rule that ln(a) - ln(b) = ln(a/b) to simplify ln 2 - ln 4:

ln 2 - ln 4 = ln(2/4) = ln(1/2)

Now, we can rewrite the expression as:

4 + ln(1/2)

We can use another logarithmic property, ln(a) + ln(b) = ln(ab), to write this as:

4 + ln(2^(-1))

Simplifying further:

4 - ln(2)

Therefore, 4 + ln 2 - ln 4 can be expressed as a single natural logarithm of:

ln(2^2 / 2) = ln(2)

So, the answer is (a) ln 2.

In general, when simplifying expressions involving logarithms, it's helpful to remember the logarithmic properties and rules, such as the product, quotient, and power rules, as well as the fact that ln(e) = 1.

The correct option is A: A linear pair is two adjacent, supplementary angles.

Supplementary angles are a pair of angles whose measures add up to 180 degrees. In other words, if we place two angles side by side, and their measures add up to 180 degrees, then they are said to be supplementary.

For example, if we have an angle with a measure of 120 degrees, then its supplementary angle would have a measure of 60 degrees, since 120 + 60 = 180. It's important to note that the two angles in a pair of supplementary angles do not have to be adjacent, meaning they can be located anywhere in a figure, as long as their measures add up to 180 degrees.

Supplementary angles play an important role in geometry and mathematics, especially when it comes to solving problems involving angles. For instance, if we know that two angles are supplementary, and we know the measure of one of the angles, we can easily calculate the measure of the other angle by subtracting the known measure from 180 degrees.

In addition, supplementary angles are often used in real-life situations, such as when designing buildings, bridges, or other structures that require precise measurements of angles.
