Can any one help me with this question

Answers

The answer to your question is: Yes.

Now, would you like to actually see the solution ?

First, multiply the quantity out:

(sin + cos)² = sin²(t) + cos²(t) + 2sin(t)cos(t)

You need to know:
==> sin²(any angle) + cos²(the same angle) = 1
==> 2sin(any angle)cos(the same angle) = sin(double the angle)

So the equation becomes:

(sin + cos)² = 1 + sin(2t)
(sin\ t+cos\ t)^2=sin^2t+cos^2t+2\cdot sin\ t\cdot cos\ t=1+sin\ 2t

Bryan started to evaluate a decimal expression. 2.5(42 ÷ 3.2 – 10(0.2) + 3)– 5.2 2.5(16 ÷ 3.2 – 10(0.2) + 3) – 5.2 What should Bryan's next step look like?

Answers

The secondstep is

2.5 (42 ÷ 3.2 – 2 + 3) - 5.2

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,

Step 1:

2.5 (42 ÷ 3.2 – 10(0.2) + 3) - 5.2

Step 2:

2.5 (42 ÷ 3.2 – 2 + 3) - 5.2

Step 3:

2.5 (13.125 + 1) - 5.2

Step 4:

2.5 (14.125) - 5.2

Step 5:

35.3125 - 5.2

Step 6:

30.1125

Thus,

The value of the expression is 30.1125.

If Sarah orders a pizza worth of $48.25 and she wants to offer 20 percent of the bill, then she needs to calculate the 20 percent of the total bill. 20 percent of $48.25 = 9.65 That mean Sarah should give $9.65 tip to pizza delivery boy.

9.65 round it up to 10. the answers A.
