Write 2 expressions using trigonometric ratios that are equivalent to 40/41.

Mathematics

Whitepunk [10]2 years ago
7 0

Answer:

cos(F) = 40/41

sin(G) = 40/41

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

... Sin = Opposite/Hypotenuse

... Cos = Adjacent/Hypotenuse

In your triangle 41 is the hypotenuse, so these two ratios are appropriate ones to use. The side of length 40 is adjacent to angle F, so

... cos(F) = 40/41

and the side of length 40 is opposite angle G, so

... sin(G) = 40/41

​(A) How many ways can a 3​-person subcommittee be selected from a committee of 6 ​people? ​(B) How many ways can a president co
Zepler [3.9K]

Answer:

A) N = 20 ways

a 3​-person subcommittee can be selected from a committee of 6 ​people in 20 ways.

B)N = 120 ways

The president, vice president and secretary can be chosen from a committee of 6 ​people in 120 ways.

Step-by-step explanation:

A) the number of ways a 3​-person subcommittee be selected from a committee of 6 ​people N;

Since there is no given order for the selection, this means that the order of selection is irrelevant. Therefore, this is a combination problem where order is not considered.

N = nCr

N = 6C3

N = 6!/3!(6-3)! = 6!/3!3!

N = 720/(6×6)

N = 20 ways

a 3​-person subcommittee can be selected from a committee of 6 ​people in 20 ways.

B) the number of ways a president, vice president and secretary can be chosen from a committee of 6 ​people N;

In this case, there is a given order of selection for the 3 posts. This is a permutation.

N = nPr

N = 6P3

N = 6!/(6-3)!

N = 6!/3!

N = 120 ways

The president, vice president and secretary can be chosen from a committee of 6 ​people in 120 ways.

The expresion 14.42d + 12.24c can be used to find the total cost of d punds of almonds and c pounds of cashews how much does it
madam [21]

Answer:

Therefore the total cost of 3\frac{1}{2} pound of almonds and 3\frac{1}{2} pound of cashews is

y=\frac{36.05}{d}+\frac{30.6}{c}

[Where y is in $]

Step-by-step explanation:

[The unit of price is not given, I assume the unit of cost as $]

Given expression is 14.42 d + 12.24 c .

Where the amount of almond is denoted by d pounds.

and  the amount of cashews is denoted by c pounds.

The cost price of d pound of almond is $14.42.

The cost price of 1 pound of almond is \$\frac{14.42}{d}

Then the cost of 3\frac{1}{2} pound of almond is =\$\frac{ 14.42 \times3 \frac{1}{2} }{d}

                                                                 =\$\frac{36.05}{d}

Again from the given expression we get that,

The cost price of c pound of cashews is $12.24

The cost price of 1 pound of cashews is =\$\frac{12.24}{c}

Then the cost of 3\frac{1}{2} pound of cashews is =\$\frac{ 12.24 \times3 \frac{1}{2} }{c}

                                                                    =\$\frac{30.6}{c}

Therefore the total cost of 3\frac{1}{2} pound of almonds and 3\frac{1}{2} pound of cashews is

y = =\frac{36.05}{d}+\frac{30.6}{c}

[Where y is in$]
