Answer:

Increase by 100%

Step-by-step explanation:

To find the percent increase/decrease:

  1. Subtract the original value from the new value.
  2. Divide by the original value.
  3. Multiply the decimal by 100 to convert to a percent.

Follow these steps below. Notice the fractions 1/2 and 1/4 have been converted to decimals to more easily work with them. Remember 1/2 = 0.5 and 1/4 = 0.25.

1/2 - 1/4 = 0.5 - 0.25 = 0.25

0.25/0.25 = 1

1*100 = 100%

Use a calculator to find a decimal approximation for the following trigonometric function sin 28°48
Bumek [7]

The decimal approximation for the trigonometric function sin 28°48' is

Given the trigonometric function is sin 28°48'

The ratio between the adjacent side and the hypotenuse is called cos(θ), whereas the ratio between the opposite side and the hypotenuse is called sin(θ). The sin(θ) and cos(θ) values for a given triangle are constant regardless of the triangle's size.

To solve this, we are going to convert 28°48' into degrees first, using the conversion factor 1' = 1/60°

sin (28°48') = sin(28° ₊ (48 × 1/60)°)

= sin(28° ₊ (48 /60)°)

= sin(28° ₊ 4°/5)

= sin(28° ₊ 0.8°)

= sin(28.8°)

= 0.481753

Therefore sin (28°48') is 0.481753.
