Draw a trapezoid and count the total lengths you have to get the answer
Exponent rule : a^-x = 1/a^x
x^-9 * x^-2 =
1/x^9 * 1/x^2 = (when multiplying exponents with same base, add exponents)
1/x^(9 + 2) =
1/x^11
Both A and B would be correct to use. You can use an example of your own to check it yourself. For example I did 10 emails all together and kept trying with the equations.
Answer:
Step-by-step explanation:
Divide 157 by 8 to see how many groups there are.
157/18=8r13. So you can round up to 9 groups of riders as there is a max of 18 at a time.
A = 225<span>°</span> in rectangular form
is written as x = cos (225) = -0.707
y = sin (225) = -0.707
The answer is y = x
This angle is in the third quadrant, x and y have the same amplitude and both are negative.
