Prove the following relations:
1) (1 - cos²A) (1 + tan²A) = tan²A​

Answers

Answer 1

Step-by-step explanation:

(1 - cos²A) (1 + tan²A) = tan²A

(sin²A)(sec²A) = tan²A

(sin²A)(1/cos²A) = tan²A

(sin²A)/(cos²A) = tan²A

tan²A = tan²A → Proved

Answer 2

Step-by-step explanation:

So, this way we can do. Thank you!

when multiplying 32 and 12 how many partial products will there be​

Answers

Answer:

12

Step-by-step explanation:

32*12  

twelve is the amount of products there will be

Multiplication is the process of multiplying. When multiplying 32 and 12, the number of partial products will there be​ 4.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The partial product technique is multiplying each digit of a number in turn with each digit of another, with each digit remaining in its original position.

The multiplication of the two given term 32 and 12 can be done as,

32 × 12

= (30 + 2) × (10 + 2)

= (30×10) + (30×2) + (2×10) + (2×2) {This are the partial products}

Hence, when multiplying 32 and 12, the number of partial products will there be​ 4.

A worker has job offers from two companies. The information below summarizes the job offer from each company.Company A:Starting salary of $31,000Raise of $3000 each yearCompany B:Starting salary of $38,000Raise of $2000 each yearPart A: Write an equation in terms of n years that can be used to determine the number of years when the salaries would be the same for both companies.Part B: Use the equation you wrote in part A to determine the number of years it would take for the salaries to be the same for both companies. Use mathematics to support your answer.

Answers

Using linear functions, we have that:

A.

For Company A: [tex]S_A(n) = 31000 + 3000n[/tex]

For Company B: [tex]S_B(n) = 38000 + 2000n[/tex]

B. The salaries will be the same after 7 years.

A linear function is given by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change.b is the y-intercept, which is the initial value.

Item a:

For Company A, the salary starts at $31,000, with a raise of $3,000 each year. Thus, [tex]b = 31000, m = 3000[/tex], and the salary after n years is given by:

[tex]S_A(n) = 31000 + 3000n[/tex]

For Company B, the salary starts at $38,000, with a raise of $2,000 each year. Thus, [tex]b = 38000, m = 2000[/tex], and the salary after n years is given by:

[tex]S_B(n) = 38000 + 2000n[/tex]

Item b:

They will be the same after n years, for which:

[tex]S_A(n) = S_B(n)[/tex]

Then

[tex]31000 + 3000n = 38000 + 2000n[/tex]

[tex]1000n = 7000[/tex]

[tex]n = \frac{7000}{1000}[/tex]

[tex]n = 7[/tex]

The salaries will be the same after 7 years.

SOLVE FOR X PLZZZZZZ

Answers

Answer:

x=5

Step-by-step explanation:

Since these angles are vertical angles formed by two parallel lines being intersected by another vertical line, you can set the 18x and 17x+5 equal to each other. Then you solve using algebra. I hope this helps!

Answer:

x=5

Step-by-step explanation:

Because they both equal 90°, you can use the equations, 18x=90 and 17x+5=90 to solve.

First, 18x= 90: (Divide by 18)

x=5

Now, 17x+5=90: (Subtract 5 from both sides)

17x= 85

Then divide by 17:

x= 5

“Devon is having difficulty determining if the relation given in an input-output table is a function.

Marco explains to him that in order to tell if the relation in the table is a function, Devon needs to check if any output values are reported. If they repeat and have different input values, the relation is not a function.

INSTRUCTIONS
If Marco is correct, respond to the following statement:
-Summarize Marco’s reasoning in your own words

If Marco is incorrect, respond to the following statement:
-Explain what is wrong with Marco’s reasoning and provide an example of a function.”

please help!!!!!

Answers

Marco is right. A function is a pattern that links in a unique way an input value with its output. So if we find different outputs for the same input, we can say that the relation is not a function.
