If sin (A + B) = 1 and cos (A - B) = 1, find A, B​

Answers

Answer 1

Step-by-step explanation:

sin (A + B) = 1 =sin 90

A+B=90 equation 1

cos (A - B) = 1=cos 0

A-B=0 equation 2

add 1 and 2

2A=90 A=45

2B=90 B=45

Solve T = M(7 + FG) for F
F =

(Answer quickly)

Answers

Answer:

F = (T - 7M) ÷ MG

Step-by-step explanation:

T = M(7 + FG)

T = 7M + MFG

T - 7M = MFG

(T - 7M) ÷ MG = F

F = (T - 7M) ÷ MG

Answer:

Step-by-step explanation:

Remove the brackets

T = 7M + FGM                    Subtract 7M from both sides

T - 7M = FGM                     Divide both sides by GM

T - 7M

======     =  F

GM

F = (T - 7M)/GM

The Solution of the Inequality is y> 2.1.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

We have,

Inequality: 2y + 7 > 15.2

Now, simplifying the inequality

2y > 15.2-7

2y > 8.2

y> 8.2 /2

y> 2.1

So, the solution is y>2.1

Answer: celsius = 5/9 (Fahrenheit - 32)

Step-by-step explanation:

Here, you want to start by looking at the fraction they give you. They say that the degrees celsius (C) are going to be equal to five ninths of (something.)

So, right now, your equation should look like this: C = 5/9 (?) because of stands for multiplication.

Next, you want to figure out what that something is. According to the reading, it'll be the degrees Fahrenheit (F) minus 32. So your something is going to look like this: (F-32)

You know that the equation is C = 5/9 (F - 32) and not C = 5/9 F - 32, because if the 32 were outside the parentheses, the prompt would be written "the temperature in degrees celsius is thirty two less than five ninths of the temperature in degrees Fahrenheit." Instead, the number 32 is explicitly included as part of the number that's being multiplied.

I hope that makes sense!

find the coordinates of each figure after the given transformation

Answers

Answer:

A'(-3, -2)

B'(-2, -1)

C'(-2, -2)

Step-by-step explanation:

The translation is (x - 7, y + 1).

That means subtract 7 from the x-coordinate and add 1 to the y-coordinate of each point.

Point A is (4, -3).

Subtract 7 from the x-coordinate 4 to get -3.

Add 1 to the y-coordinate -3 to get -2.

For point A, you get A'(-3, -2) after the translation.

Do the same with points B and C.

B(5, -2) ---> B'(5 - 7, -2 + 1) = B'(-2, -1)

C(5, -3) ---> C'(5 - 7, -3 + 1) = C'(-2, -2)
