Step-by-step explanation:

Finding slopes of the lines to determine their relationship

1. J(1, 9), K(7, 4), L(8, 13), M(-2, 1)

Slope of JK

m = (4-9)/(7-1) = -5/6

Slope of LM

m = (1-13)/(-2-8) = -12/-10 = 6/5

These lines are perpendicular as slopes are negative reciprocal

2 J(13, -5), K(2, 6), L(-1, -5), M(-4, -2)

Slope of JK

m = (6-(-5))/(2-13) = 11/(-11) = -1

Slope of LM

m = (-1-(-5))/(-4-(-1)) = 4/(-3) = -4/3

Lines are neither parallel nor perpendicular

3. J(-10, -7), K(-4, 1), L(-3, 2), M(-6, -2)

Slope of JK

m = (1-(-7))/(-4-(-10)) = 8/6 = 4/3

Slope of LM

m = (-2-2)/(-6-(-3)) = -4/-3 = 4/3

These lines are parallel as slopes are same

a) 2/19
b) -19/2
c) -2/19
d) 19/2

Answers

Answer:

19/2

Step-by-step explanation:

This problem is a problem desgined to test your basic understanding of Trigonomic functions and there applictoins.

Sec theta is the inverse of cos theta, which means sec theta is equal to adjecent / opposite.

They already gave you cos theta which is 2/19

We should know that from 0 to 90 degrees, sec theta is postive.

so sec theta is 19/2

Answer:

The explicit formula that represents the amount of money left on the card

is a[tex]_{n}[/tex] = 53.25 - 3.25n

The value of the card after 12 lunches is $14.25

Step-by-step explanation:

The explicit formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where

a[tex]_{n}[/tex] is the nth terma is the first termd is the common difference between each 2 consecutive terms

In the question

∵ You have 50 dollars

∵ The money left after lunch on Monday is 46.75 dollars

∵ The money left after lunch on Tuesday is 43.50 dollars

∴ The terms of the sequence are 50, 46.75, 43.50

∵ 46.75 - 50 = -3.25

∵ 43.50 - 46.75 = -3.25

→ That means there is a common difference between each 2 terms

∴ d = -3.25

∵ a = 50

→ Substitute the values of a and d in the rule above

∴ a[tex]_{n}[/tex] = 50 + (n - 1)(-3.25)

→ Simplify it

∵ a[tex]_{n}[/tex] = 50 + -3.25(n) + -3.25(-1)

∴ a[tex]_{n}[/tex] = 50 - 3.25n + 3.25

→ Add the like terms

∴ a[tex]_{n}[/tex] = 53.25 - 3.25n

∴ The explicit formula that represents the amount of money left on the

   card is a[tex]_{n}[/tex] = 53.25 - 3.25n

∵ n is the number of lunches

∴ n = 12

→ Substitute n by 12 to find the amount of money left on the card

∵ a[tex]_{12}[/tex] = 53.25 - 3.25(12)

∴ a[tex]_{12}[/tex] = 14.25

∴ The value of the card after 12 lunches is $14.25

Tony hit 9 out of 15 pitches at baseball practice yesterday. The following day at practice 45 pitches were made. How many pitches did Tony miss?

Answers

Answer:

18 pitches.

Step-by-step explanation:

I'm assuming the "9 out of 15" is the fraction of pitches Tony hit at baseball practice.

Hence, Tony missed 6 out of 15 pitches.

6/15 * 45

= 6 * 3

= 18 pitches.

Hope this helped!

Answer:

18

Step-by-step explanation:

You have to start with how many he hit.

Let the number of pitches he hit = x

9/15 = x / 45            Cross multiply

15x = 9 * 45             Combine the right side

15x = 405                Divide by 15

x = 405/15

x = 27

===================

The number he missed is 45 - 27 = 18

Over the last week, the daily low temperatures in degrees Fahrenheit have been −2, 6.9, 17 1 2 , −5.1, 24, − 1 4 , and 1.45. List these numbers in order from greatest to least.

Answers

Answer:

24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

Step-by-step explanation:

Given the following temperature values :

2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.

Ordering the values above from greatest to least ; (descending order)

Expressing all temperature values in the same format :

Let's make sure all values are in decimal to make comparison easier :

2.0

6.9

17 1/2 = 35/2 = 17.5

-5.1

24.0

-1/4 = - 0.25

1.45

We begin from the temperature value which is highest :

24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1

Hence ;

24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Length of the Bus = 33.5 feet.

Length of the City train:

= Length of the Bus + 45.9

= 33.5 + 45.9

= 79.4 feet.

Thus,

The city train is 79.4 feet.

Answer:

x = 6

Step-by-step explanation:

Vertical angels are always equal, there fore angle A = angle B.

If angle A = angle B, and

angle A = 3x - 9 and angle B = x + 3, then

3x - 9 = x + 3

Now you can solve this like a regular inequality

Start by subtracting x by it's self then 3x to get both variables on one side.

2x - 9 = 3

Now you can add 9 to it's self and to 3 on the other side.

2x = 12

Finally, divide 2 by it's self and 12.

x = 6
