Answer:

3.4

Step-by-step explanation:

The opposite of a number is the same as the additive inverse of the number.

Two numbers are opposites, or additive inverses, if they add to zero.

For a positive or a negative number, just change its sign to find its opposite. For zero, its additive inverse is zero.

The opposite of -3.4 is 3.4.

Answer: 3.4

Select all of the given trigonometric equations that are true statements. sin(180°) = cos(0°) cos(74°) = sin(16°) sin(20°) = cos

lara [203]

Answer:

Cos 74°= Sin 16°

Sin 20°= Cos 70°

Sin A°=Cos (90°- A°)

Step-by-step explanation:

This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.

Complete the table by converting each decimal to a fraction. Show your work. Repeating decimals. 0.2, 0.5, 0.7

Part 1 = 2/9

Part 2 =5/9

Part 3 =7/9

<u>Explanation</u>

To convert the a repeating decimals this are the steps;

Part 1

Let x = 0.222222... (i)

10x = 2.222222... (ii)

Subtract equation (i) from equation(ii)

10x = 2.222222....

9x = 2.00000..

∴ 9x = 2

Divide by 9 both sides;

x = 2/9

Part 2

Let x = 0.5555...

10x = 5.5555...

subtract equation (i) from equation (ii).

10x = 5.5555..

9x = 5.0000..

∴ 9x = 5

x = 5/9

Part 3

Let x = 0.7777....

10x = 7.7777...

Subtracting equation (i) from equation (ii)

10x = 7.7777...

9x = 7.000..

∴ 9x = 7

x = 7/9

Pattern noted

When converting the repeating decimals to fraction only one number was repeating. This made the three decimals have the same fraction.
