8 0
So hmm notice the picture below

that's (0, -3)

now, keep in mind, adjacent is 0, opposite is -3, and hypotenuse, or radius, is 3

and recall  sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
\qquad \qquad 
% cotangent
cot(\theta)=\cfrac{adjacent}{opposite}
\\ \quad \\

% cosecant
csc(\theta)=\cfrac{hypotenuse}{opposite}
\qquad \qquad 
% secant
sec(\theta)=\cfrac{hypotenuse}{adjacent}

Been a while since I’ve needed to not use a calculator. Why is -2X10^-18 (3/16) = 4.09X10^-19?
Anestetic [448]

Answer:

see the explanation

Step-by-step explanation:

we have

2.18*10^{-18}(\frac{3}{16})

we have that

\frac{3}{16}=0.1875

Convert to scientific notation

0.1875=1.875*10^{-1}

substitute

2.18*10^{-18}(1.875*10^{-1}})

Remember that

To multiply two numbers in scientific notation, multiply their coefficients and add their exponents

2.18*10^{-18}1.875*10^{-1}}=(2.18*1.875)*10^{(-18-1)}=4.0875*10^{-19}

Round the number 4.0875 two decimal places

so

4.0875*10^{-19}=4.09*10^{-19}

Point B, located at (-5, -8), is rotated 360°. What are the coordinates of point B?
Natalka [10]
(-5,-8)
The coordinates are still the same because a rotation of 360° is a complete circle, therefore the points remain in the same spot.
