Suppose sin(A) = 1/4. use the trig identity sin^2(A)+cos^2(A)=1 to find cos(A) in quadrant II. around to ten-thousandth.
larisa86 [58]

In quadrant II, \cos(A) will be negative. So

\sin^2(A) + \cos^2(A) = 1 \implies \cos(A) = -\sqrt{1 - \sin^2(A)} = -\dfrac{\sqrt{15}}4 \approx \boxed{-0.9682}

When you mix two colors of paint in equivalent ratios, the resulting color is
vredina [299]

Answer:

Step-by-step explanation:

From the given table,

To prepare a mixture of a paint, two paints of different shades have been added in the same ratio,

Since, 2 cups of blue paint are mixed with 10 cups of yellow paint

Therefore, ratio in which these shades have been added = \frac{\text{Pink}}{\text{Blue}}

                                                                                                = \frac{10}{2}

                                                                                                = \frac{5}{1}

                                                                                                = 5 : 1

For 1 cup of blue paint number of cups of yellow paint required,

\frac{x}{1}=\frac{5}{1}

x = 5 cups

For 3 cup of blue paint number of cups of yellow paint required,

\frac{x}{3}=\frac{5}{1}

x = 15 cups

Cups of blue paint                Cups of yellow paint

            2                                             10

            1                                               5

            3                                              15
