ABDC is a quadrilateral with two non-parallel sides. It has two pairs of opposite sides which are parallel. It is also known as a trapezoid.

ABDC is a four-sided figure with two pairs of opposite sides that are parallel. This type of quadrilateral is also known as a trapezoid. A trapezoid has two non-parallel sides, while the other two sides are parallel to each other. In this case, the two parallel lines are L1 and L4, while L2 and L3 are the two non-parallel sides. We can see that the point C on L2 is a distance of 4cm from L1, and L4 is a line that is parallel to L1 and passes through C. Finally, L4 intersects L3 at the point D, which completes the trapezoid ABDC.

The length of AB can be determined by using the Pythagorean Theorem. We know that the length of L1 is 8 cm, so the length of AB is 3 cm.

example

AB = √(8^2 - 4^2) = √64 - 16 = √48 = 6 cm

The length of BD can also be determined by using the Pythagorean Theorem. We know that the length of L2 is 4 cm, so the length of BD is 3 cm.

BD = √(4^2 - 4^2) = √16 - 16 = 0 cm

The area of the shaded region in the rectangle is given as follows:

42 units squared.

The area of a rectangle of base b and height h is given by the multiplication of these dimensions, as follows:

Area = base x height.

For the shaded region in this problem, given by the image shown at the end of the answer, the area can be obtained as the subtraction of the area of the entire rectangle by the area of the non-shaded region.

The entire rectangle has base 11 and height 12, hence it's area is given as follows:

Ar = 11 x 12 = 132 units².

The non-shaded region has base of 9 units and height of 10 units, hence it's area is given as follows:

An = 9 x 10 = 90 units².

Then the area of the shaded region on the rectangle is calculated as follows:

As = Ar - An = 132 - 90 = 42 units².

The function is called an if/else statement function lets you test if something is true or false and then do different things depending on which result you get.

An if/else statement is a type of control flow statement that allows a program to execute different instructions depending on the result of a logical expression. The statement begins with an if condition, followed by a set of instructions to be performed if the condition is true. If the condition is false, the program executes the instructions after the optional else statement. The syntax for an if/else statement looks like this: if (condition) { // Instructions to execute if condition is true } else { // Instructions to execute if condition is false } By using an if/else statement, a program can make decisions and perform different actions based on the results of a logical expression.

The predicted value of the car in 2009, to the nearest dollar, is $14,800.

The value of an exponentially depreciating asset can be calculated using the equation:

V = V_0 × [tex]e^{(-r*t)}[/tex]

where V is the current value of the asset, V_0 is the initial value of the asset, r is the rate of depreciation, and t is the time elapsed since the asset was purchased.

In this case, the initial value of the car was $27,600, the value in 2004 was $8,300, and the time elapsed since the car was purchased is 4 years.

To determine the predicted value of the car in 2009, we can set t equal to 9 years and solve for V:

V = 27,600 × [tex]e^{(-r*9)}[/tex] = 8,300

Solving for r gives us:

r = ln(8,300/27,600) / -9

= -0.069

To determine the predicted value of the car in 2009, we can plug the value for r into the equation and solve for V:

iii)1 number followed by 5 letters : 10^1*26^5= 118,813,760

b)...

a) If Eddie repeat a digit or a letter:

i) The number of codes he can create with 6 numbers is 1,000,000.

ii) The number of codes he can create with 4 numbers followed by 2 letters is 67,600.

iii) The number of codes he can create with 1 number followed by 5 letters is 11,881,376.

b) If Eddie does not want to repeat a digit or a letter:

i) The number of codes he can create with 6 numbers is 15,120.

ii) The number of codes he can create with 4 numbers followed by 2 letters is 1,092,000.

iii) The number of codes he can create with 1 number followed by 5 letters is 7,893,600.

a) To calculate the number of codes Eddie can create for each scenario:

i) For a 6-digit code using only numbers, each digit can take on any value from 0 to 9 (10 options for each digit). So, the total number of codes is 10⁶ = 1,000,000.

ii) For a code with 4 numbers followed by 2 letters, there are 10 options for each digit and 26 options for each letter (assuming only uppercase letters). The total number of codes is 10⁴ * 26² = 67,600.

iii) For a code with 1 number followed by 5 letters, there are 10 options for the number and 26 options for each letter. The total number of codes is 10 * 26⁵ = 11,881,376.

b) If Eddie decides not to repeat a digit or a letter, the number of possibilities changes for each scenario:

i) Since he cannot repeat a digit, the first digit can be any of the 10 options. The second digit has only 9 options left, the third digit has 8 options, and so on. So, the total number of codes becomes 10 * 9 * 8 * 7 * 6 * 5 = 15,120.

ii) In this case, he cannot repeat any digit or letter. So, for the 4 numbers, there are 10 options for the first, 9 options for the second, 8 options for the third, and 7 options for the fourth. For the 2 letters, there are 26 options for the first and 25 options for the second (since no repetition is allowed). The total number of codes becomes 10 * 9 * 8 * 7 * 26 * 25 = 1,092,000.

iii) For the code with 1 number and 5 letters, the number has 10 options, and the first letter has 26 options. However, he cannot repeat any letter after the first, so the second letter has 25 options, the third has 24 options, and so on. The total number of codes becomes 10 * 26 * 25 * 24 * 23 * 22 = 7,893,600.

37°

Step-by-step explanation:

The outer quadrilateral in black is a rectangle because of the angles it has at the vertices.

Look at the upper green line. It intersects the vertical sides of the outer rectangle.

The upper green line intersects the left vertical segment of the outer rectangle at a 103° angle. That makes the top yellow box 77°.

The top yellow box is an angle of a quadrilateral.

360 - 77 - 66 - 114 = 103

The second yellow box is 103°.

The third yellow box is 77°.

The bottom yellow box is 180 - 66 - 77 = 37°

The length of p is 411 cm.

Every three-sided polygon having three edges and three vertices is referred to as a triangle in geometry. The most important attribute of a triangle is that its internal angles sum to 180 degrees. The triangle's angle sum attribute is what is known as.

As per the given data:

We are given a triangle, and we know 2 angles of the triangle and one side.

In ΔPQR:

r = 38 cm

∠P = 49°

∠Q = 127°

From the angle sum property for a triangle:

∠P + ∠Q + ∠R = 180°

49° + 127° + ∠R = 180°

∠R = 180° - 176°

∠R = 4°

By using the sine rule in a triangle:

sin(∠P)/p = sin(∠R)/r

p = [sin(∠P)/sin(∠R)] × r

p = [sin(49°)/sin(4°)] × 38

p = 411 cm

The length of p is 411 cm.

Hence, the length of p is 411 cm.

The sum of the three angles in any triangle is always 180°.

Knowing that the sum of the angles of triangle is 180° can help you to solve problems about triangles.

Angles

In this triangle, angle b is a right angle and angle c = 40°. What is the measure of angle a?

a + b + c = 180°

Since b is a right angle, b = 90°.

The problem states that c = 40°.

Therefore, a + 90° + 40° = 180°

a + 130° = 180°

a + 130° − 130° = 180° − 130°

a = 50°

The number of miles Joseph traveled in one hour is calculated to be 20.25 miles

Since Joseph drove 27 miles in 1 1/3 hours, we first convert 1 1/3 into simpler form as follows;

1 1/3 hours = 4/3 hours

Now we can determine how far he traveled in one hour if he drove at a constant rate by cross multiplication as follows;

4/3 hours = 27 miles

1 hour = x

Here x represents the number of miles traveled in one hour;

1 × 27 = 4/3x

27 = 4/3x

x = 27/(4/3)

x = 27 × 3/4

x = 20.25 miles

Hence Joseph travels 20.25 miles in one hour.

If the sales tax is 6. 35% then Claire's total is $15.63

In this questiion we have been given Claire buys a pair of earrings for $4, a necklace for $10, and a ring for $7.

So, her total purchase is:

4 + 10 + 7 = 21 dollars

She has a 30% off coupon for her whole transaction.

We find the 30 percent of 21

(30/100) * 21 = 6.3 dollars

So, she will get discount of 6.3 dollars.

So, the amount would be,

21 - 6.3 = $14.7

The sales tax is 6. 35%

Now we find 6.35 percent of 14.7

6.35% of 14.7
