If tan 0=3/4 find sin0
bija089 [108]

Answer:

sin O = \frac{3}{5}

Step-by-step explanation:

given tan O = \frac{3}{4} = \frac{opposite}{adjacent}

Then this is a right triangle with legs 3 and 4

Using Pythagoras' identity then the hypotenuse (h ) is

h = \sqrt{3^2+4^2} = \sqrt{25} = 5, hence

sin O = \frac{opposite}{hypotenuse} = \frac{3}{5}

To increase and decrease an amount by 7%, what single multiplier would you use?
Mila [183]

We will solve the problem for both cases:


Case 1:

If the amount increases by 7% we have the number for which we are going to multiply is given by:

x = (\frac{1}{100}) * (100 + 7)

x = (\frac{1}{100}) * (107)\\x = 1.07


Case 2:

If the amount decreases by 7% we have the number for which we are going to multiply is given by:

x = (\frac{1}{100}) * (100-7)

x = (\frac{1}{100}) * (93)\\x = 0.93


Answer:

single multiplier you would use for each case is:

x = 1.07 (increase)

x = 0.93 (decrease)
