The sin of any angle = cos(90  -  the angle used for the sine)

Sin(64) = cos(90 - 64)

Sin(64) = cos(26)

Check

Sin(64) = 0.8988

Cos(26) = 0.8988

The total amount of deductions from an employee’s gross pay is $83.20. If the gross pay is $378.18, what percent of their gross
Masja [62]

Answer:

22%

Step-by-step explanation:

A percent of something can be thought of as part of that thing divided by the total amount of the same thing and multiplied by 100%.

In this case, the part of the thing is part of a paycheck. The total thing is the total paycheck.

Percent=\frac{Part}{Total} *100%%

Percent=\frac{83.20}{378.18} *100=0.2200*100=22.000%

Olenka [21]

Answer:

494018

Step-by-step explanation:

you are trying to find the diameter of the circle, it is usually half the length of a radius, but since 497 squared is how long a radius is (unless the question asked that the area if 497 inches squared), i can't really give you a clear answer, but the diameter is 247009 times 2 which is 494018

Determine the slope of the line passing through the points (5,6) and (-5,-1)m=____
EleoNora [17]

GIVEN:

We are given two points on a line and these are;

A=(5,6),\text{ }B=(-5,-1)

Required;

We are required to determine the slope of the line passing through these points.

Step-by-step solution;

The slope of a line is given by the formula;

m=\frac{y_2-y_1}{x_2-x_1}

The variables are;

\begin{gathered} (x_1,y_1)=(5,6) \\  \\ (x_2,y_2)=(-5,-1) \end{gathered}

We can now substitute these into the formula and then simplify;

\begin{gathered} m=\frac{-1-6}{-5-5} \\  \\ m=\frac{-7}{-10} \\  \\ m=\frac{7}{10} \end{gathered}

ANSWER:

The slope of the line passing through the given points is;

m=\frac{7}{10}
