Now, according to the opposite angle theorem,

Angle ABC is 31°.

And Angle ACB = 180° - 43° - 31° = 106°

Thus, Angle ACD = 180° - 106° = 74°.

Angle ADC= 180° - 107° =73°

Angle CAD(x) = 180° - 73°-74°

= 33°

A thief steals an ATM card and must randomly guess the correct pin code that consists of 4 digits (0 through 9) that must be entered in the correct order. Repetition of digits is allowed.
What is the probability of a correct guess on the first try?

Answers

Answer:

$\frac{1}{10000} = 0.0001$ probability of a correct guess on the first try.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Only one correct key, so $D = 1$

Total outcomes:

4 digits, each with 10 possible outcomes. So

$T = 10^4 = 10000$

What is the probability of a correct guess on the first try?

$p = \frac{D}{T} = \frac{1}{10000} = 0.0001$

$\frac{1}{10000} = 0.0001$ probability of a correct guess on the first try.

What is the inverse of the function f(x) = 169x2 when x ≥ 0?

A- f−1(x) = 13‾‾
B- f−1(x) = √13
C- f−1(x) = 13x
D- f−1(x) = 113

Answers

Answer:

$f^{-1}(x) = \frac{\sqrt{x}}{13}$

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse, we exchange the y and the x values, and then isolate y.

Function:

$f(x) = 169x^2$

That is:

$y = 169x^2$

Exchanging x and y:

$x = 169y^2$

Isolating y:

$y^2 = \frac{x}{169}$

$y = \sqrt{\frac{x}{169}}$

$y = \frac{\sqrt{x}}{13}$

$f^{-1}(x) = \frac{\sqrt{x}}{13}$

Which of the following is another way to label Plane J?
Select one: Plane h Plane
ABD Plane EFG Plane ADF
Check

Answers

Plane ADF is another way to label Plane J.

In order to determine which of the given options is another way to label Plane J, we need to first identify the key characteristics of Plane J.

These characteristics are its points, lines, and planes that it contains. We can then use these characteristics to compare and match them with the given options.

Here are the key characteristics of Plane J: Points: J, A, D Lines: JA, JD, AD Planes: Plane J Now let's examine each option to see which one matches the characteristics of Plane J: Option A: Plane h This option is not a match since Plane h is not one of the planes that contain the points J, A, and D.

Option B: Plane ABD This option is not a match since Plane ABD contains points A, B, and D but not point J.

Option C: Plane EFG This option is not a match since Plane EFG contains points E, F, and G but not point J.

Option D: Plane ADF This option is a match since Plane ADF contains points A, D, and F which are all points that are contained in Plane J.

Therefore, Plane ADF is another way to label Plane J.

the scale of a map says that 4 cm represents5 km.What distance on the map in centimeters represents an actual distance of 4 kilometers

Answers

Answer:

3.2 cm

Step-by-step explanation:

If we know that our ratio is 4 cm: 5 km. We can find the unit rate of the scale. Which would be 0.8 cm: 1 km. After we find the unit ratio we can then multiply both sides by 4. (4 * 0.8) : (4*1) After simplifying we get the ratio of 3.2cm: 4 km.

Y=2X squared -12 X +20 for quadratic formula

Answers

x = (12 ± √(-16)) / 4,The solutions would be complex numbers.

What is the quadratic formula?

To solve quadratic equations of the form ax2 + bx + c = 0, use the quadratic formula. For this situation, your condition is as of now as a quadratic condition, with a = 2, b = - 12, and c = 20.

The quadratic formula is:

x = (-b ± √$(b^2 - 4ac)$) / 2a

Plugging in the values for a, b, and c, we get:

x = (-(-12) ± √$((-12)^2 - 4(2)(20)))$ / 2(2)

Simplifying the expression inside the square root:

x = (12 ± √$(144 - 160)$) / 4

x = (12 ± √(-16)) / 4

Since the square foundation of a negative number is definitely not a genuine number, this condition has no genuine arrangements. Complex numbers would provide the answers.

In circle N with � ∠ � � � = 12 4 ∘ m∠MNP=124 ∘ and � � = 13 MN=13, find the area of sector MNP. Round to the nearest hundredth.

Answers

If circle with center N with m∠MNP=124 ∘ and MN=13, the area of sector MNP is approximately equal to 194.86 square units.

To find the area of a sector of a circle, we need to use the formula:

Area of sector = (central angle/360°) x πr²

Where r is the radius of the circle.

In this problem, we know that the central angle m∠MNP is 124° and MN, which is also the radius of the circle, is 13. So we can substitute these values into the formula:

Area of sector = (124/360) x π(13)²

Area of sector ≈ 194.86

Therefore, the area of sector MNP is approximately equal to 194.86 square units.

How to explain parallel lines

Parallel lines are two lines on a two-dimensional plane that, no matter how far they are extended, never collide. They always keep the same gap between them.

Parallel lines have the same slope, which means they have the same angle of inclination or steepness. In other words, they rise and fall at the same pace along their length.

Parallelogram

Opposite sides of a parallelogram are the same length, so ...

Additional comment

In a parallelogram, opposite sides are parallel and are the same length. Opposite angles have the same measure, and adjacent angles are supplementary. The diagonals bisect each other, but are usually different lengths and usually do not cross at right angles.

(If diagonals are the same length, it is a rectangle; if they cross at right angles, it is a rhombus. A rectangular rhombus is a square.)

Answer:

Infinitely many solutions

Step-by-step explanation:

(1) ---- 6x - 4y = 9

(2)---- 12x - 8y = 18

If you multiply (1) by 2 → 12x - 8y = 18 --- (3)

and then when you compare (2) and (3), you'll find that you still can't find the value of X and Y therefore, there's infinitely many solutions

Answer:

Infinitely Many Solutions!!

Step-by-step explanation:

You need to do elimination method!!

This is because we need to top the equation to cancel out and become negative.

6x−4y=9

12x−8y=18

You could do 6x and everything multiplied by -2. But 4y can do the same too!!

I rather do 4y x -2!

-12x+8y=-18

12x−8y=18

Everything cancels out!!

0=0

But 0 equals to 0 goes on forever so the answer is infinite solutions!!

**The reasoning behind the two other choices**

No solution would be like -3=0 which is not our case!!

One solution has something that goes into everything evenly!

The entire surface of a three-dimensional shape is referred to as its surface area. A cuboid with six rectangular faces has a surface area equal to the sum of the areas of each face. Alternatively, you can label the cuboid's length, width, and height (l, w, and h), then calculate its surface area (SA) using the formula: SA=2lw+2lh+2hw.
