Write the equation of the line that has an undefined slope and passes
through the point (-4. –5).

Answers

Answer:

x = -4

Step-by-step explanation:

If a line has an undefined slope, it is a vertical line.

If we want a vertical line to include (-4, -5), every x-value will be -4.

This means our equation is:

x = -4

A padlock's combination is four digits long.
Please show your work

Answers

Answer:

10,000

Step-by-step explanation:

Highest 4 digit number: 9999

Lowest possibility: 0000

9999-0000=9999

The 0000 is 1 number

9999+1=10,000

Answer:

1000 possible combinations

Step-by-step explanation:

For the padlock combination code, each number can be one of 10 (0-9).

This means there are 10 possibilities for the first digit, 10 for the 2nd, 10 for the 3rd, and 10 for the 4th.

If we combine all these possibilities between the different digits we get:

10 x 10 x 10 x 10 = 1000 different combinations.

What is the slope of the line that passes through the points (-2,-5) and (18, –5)?
Write your answer in simplest form.

Answers

Answer:

0

Step-by-step explanation:

Slope = [tex]\frac{y2-y1}{x2-x1}[/tex]

(-2,-5) = (x1,y1)

(18,-5) = (x2,y2)

Slope = [tex]\frac{-5+5}{18+2}[/tex]

          = [tex]\frac{0}{20}[/tex]

          = 0

On which line did Malik make his mistake? Explain Malik's mistake using the complete the square method in 1-3 complete sentences.

Answers

Completing the square method rearranges the equation to have the

square of linear equation and constant on both sides of the equation.

Responses:

The mistake is made in line 4The mistake is in not taking the square root of both sides

Which is the correct completing the square method?

The given equation is; x² - 10·x - 11 = 0

Line 1: p² - 10·p - 11 = 0

Which gives;

p² - 10·p = 11

Adding 25 to both sides gives;

Line 2: p² - 10·p + 25 = 11 + 25

11 + 25 = 36

Factorizing p² - 10·p + 25 = (p - 5)·(p - 5)  = (p - 5)²

Line 3: (p - 5)² = 36

Which gives;

p - 5 = ±√36

Line 4: p - 5 = √36 = 6 or p - 5 = -√36 = -6 (Line that has a mistake)

Line 5: p = 6 + 5 = 11, or p = -6 + 5 = -1

Line 6: p = 11 or p = -1

The line Malik made a mistake is on line 4

The mistake made is that in line 4, the root of both sides of the equation, rather than only the left side of the equation is to be taken.

The constant on the left and side is then subtracted from the positive

and negative value of the square root of the right hand side to give two

results.

Combined liked terms

you can see that there is X on both sides and the lowest one has a +10 and the highest has a +12 so it will always be greater by 2

Pythagorean theorem

in right angled triangles there is a relationship that governs the length of the tree sides. if we knows the length of any two sides, the third side maybe calculated by the use of the Pythagorean theorem.

At 12:15, the end of the minute hand of a clock is 8 feet above the ground. At 12:30, it is 6.5 feet off the ground How long is the minute hand of the clock? And How high is the center of the clock from the ground

Answers

Answer:

Length of minutes hand= 1.5 feet

Height of the center of the clock from the ground= 8 feet

Step-by-step explanation:

At 12:15, the end of the minute hand of a clock is 8 feet above the ground.

At 12:15 the minutes hand is making a radius along the diameter of the clock which means it is at the center of the clock. In other the center of the clock is 8 feet above the ground.

At 12:30, it is 6.5 feet off the ground .

This tells length of the minutes hand the clock which is the distance from the ground minus the distance off the ground

= 8-6.5= 1.5 feet

The center of the clock is 8 feet from the ground.

The length of the minute hand is 1.5ft, the distance of the center of the clock from the ground is 8ft

To solve this problem, we have to apply logical reasoning here.

Length of the Minute Hand

To calculate the length of the minute hand, we just have to subtract or find the difference between the minute and from the ground at 12:30 to the minute hand at 12:15.

This will give us

[tex]12:15 - 12:30 = 8 - 6.5 = 1.5ft[/tex]

Distance of the Center of the clock from the ground

The distance of the center of the clock from the ground can be gotten from the distance from the ground at 12:15. This is because at 12:15, the minute hand is at the same horizontal line with the center of the clock and this makes the distance of the center of the clock from the ground is 8ft.

From the above,

The length of the minute hand is 1.5ft The distance of the center of the clock from the ground is 8ft
