The required value of x for the given figure is 2√7 units.

What is right angled triangle?

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangled triangle, is a triangle with one right angle, or two perpendicular edges. The foundation of geometry is the relationship between the sides and other angles of the right triangle.

According to question:

In the given figure we have two triangle big and small triangle.

To find the value of x;

first we use Pythagoras theorem in big triangle.

So; let base of big triangle is b

9² = 7² + b²

b² = 81 - 49

b = √32

Now in small triangle;

(√32)² = x² + 2²

32 = x² + 4

x² = 28

x = √28

x = 2√7 units.

Thus, required value of x is 2√7 units.

Part B
Interest can be calculated on money invested and money borrowed. Based on her four options, in which account should
Brianna choose to invest her summer earnings?
Use your answers from Part A to justify your response. Explain your reasoning using complete sentences.

Answers

Based on the four options, Brianna should choose to invest her summer earnings in the Account 4 (compounded continuously) because interest is at highest in the account after like 3 years.

Why is interest higher when compounded continuously is used?

Interest is higher in compounded continuously because it is calculated more frequently than in other compounding methods, such as annually or semi-annually. In continuous compounding, interest is calculated and added to the principal an infinite number of times over a given period, which results in a higher effective interest rate than other compounding methods.

This means that the amount of interest earned on an investment or loan increases more rapidly, which can result in greater returns for investors or higher costs for borrowers. Continuous compounding is often used in financial markets where small changes in interest rates can have significant impacts on returns, such as in the case of short-term bonds or options trading.

How many more saplings with a height of 27 1/4 inches or less were there than saplings with a height greater than 27 1/4 inches?

Answers

(Total saplings- Saplings with a height greater than 27 1/4 inches) = Number of saplings with a height of 27 1/4 inches or less.

How to find height of an object?

To find the height of an object in mathematics, you must first identify the shape of the object. Then, use the relevant formula for the shape to calculate the height. For example, if the object is a right triangle, the height can be found by using the Pythagorean Theorem. Additionally, if the object is a rectangle, you can use the formula for the area of a rectangle to calculate the height. Finally, if the object is a circle, you can use the formula for the circumference of a circle to find the height.

To solve this question, we will use the numerical approach. First, we need to subtract the number of saplings with a height greater than 27 1/4 inches from the total number of saplings. Then, we subtract the result from the total number of saplings. The result will be the number of saplings with a height of 27 1/4 inches or less.

Therefore, the equation is (Total saplings- Saplings with a height greater than 27 1/4 inches) = Number of saplings with a height of 27 1/4 inches or less.

Explain about the distance formula?The distance formula is still a formula used to determine how far apart two places are from one another. The dimensions of these points are unlimited. For instance, you could need to determine the separation between two points in space, a plane, or a line (1, 2, or 3 dimensions) .

Using the formula obtained from Pythagoras' theorem, distance can be computed.

The distance formula in coordinate geometry is:

(P, Q) = √ (x2 – x1)² + (y2 – y1)².

Given points: (5, 4) and (−3, −1)

d = √ (-3 - 5)² + (4 + 1)²

d = √ 64 + 25

d = √ 89

d = 9.43

The value of y, given that Triangle FEG is similar to Triangle IHJ is 10.

How to find the value of y ?

Seeing as Triangle FEG is similar to Triangle IHJ, we can assume that angle EGF is the same as angle HJ1.

This means that 5 y + 8 is equal to 58 degrees.

The value of y is therefore :

5 y + 8 = 58

5 y = 50 - 8

y = ( 50 - 8 ) / 5

y = 50 / 5

y = 10

In conclusion, given the two similar triangles and the angles EGF and HJI, the value of y can be found to be 10.

5,10,15,20,25 is this an arithmetic or geometric sequence

Answers

Because of the common difference of 5, this series is math because it has a common difference of 5.

What in mathematics is an arithmetic sequence?

An arithmetic series is one in which each term grows by adding or removing a certain number, k. In a geometric series, each term grows by dividing by or increasing by a certain constant k. For instance, a1 = 25 and a(n) Equals a(n-1) Plus 5.

This is a list of numbers.

Each term in an arithmetic series is created by adding a fixed difference to the term before it. The distance between successive words in this order is 5:

10 - 5 = 5

15 - 10 = 5

20 - 15 = 5

25 - 20 = 5

Therefore, this sequence has a common difference of 5, which means it is an arithmetic sequence.

5. What is your net pay, if you have Federal taxes taken out at 14%, State taxes at 4.5% and FICA at 6%?

Answers

Answer:

   1. Gross pay = hourly rate x hours worked

   Gross pay = $14 x 32 = $448

   2. Net pay = gross pay - deductions

   Federal taxes = 10% of gross pay = 0.1 x $448 = $44.80

   State taxes = 4.5% of gross pay = 0.045 x $448 = $20.16

   FICA = 6% of gross pay = 0.06 x $448 = $26.88

   Total deductions = $44.80 + $20.16 + $26.88 = $91.84

   Net pay = $448 - $91.84 = $356.16

   3. Gross pay = hourly rate x hours worked

   Gross pay = $17 x 40 = $680

   4. Regular pay = hourly rate x hours worked

   Regular pay = $20 x 40 = $800

   Overtime pay = (hourly rate x 1.5) x overtime hours

   Overtime pay = ($20 x 1.5) x 5 = $150

   Gross pay = regular pay + overtime pay

   Gross pay = $800 + $150 = $950

   5. Net pay = gross pay - deductions

   Federal taxes = 14% of gross pay = 0.14 x $950 = $133

   State taxes = 4.5% of gross pay = 0.045 x $950 = $42.75

   FICA = 6% of gross pay = 0.06 x $950 = $57

   Total deductions = $133 + $42.75 + $57 = $232.75

   Net pay = $950 - $232.75 = $717.25

Find the value of x.
Leg= 8
Leg=x-4
Hypotenuse=8

Answers

The value of x is 10 if Leg= 8 and Leg=x-4.

What is Pythagoras theorem?

This states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

In this scenario we were given

Leg= 8

Leg=x-4

Hypotenuse=x

Therefore : x² = 8² + (x-4)²

x² = 64 + x² - 8x + 16

x² -  x² = 80 - 8x

8x = 80

x = 80/8 = 10

Therefore hypotenuse is 10 and the length of the other side is (10-4) = 6.

What is Chain Rule?

The chain rule states that the derivative D of a composite function is given by a product, as D(f(g(x))) = Df(g(x)) ∙ Dg(x).

In other words, the first factor on the right, Df(g(x)), indicates that the derivative of f(x) is first found as usual, and then x, wherever it occurs, is replaced by the function g(x).

Given:

By chain rule we can write z= f(x, y) = f( x(t), y(t))

dz/ dt = df/ dx . dx/ dt + df/ dy. dy/dt

So, df/ dx = [tex]e^y[/tex]

df/dy =   [tex]e^y[/tex] + (x+ y)  [tex]e^y[/tex]
