Answer:
Your teacher messed up the question so just put the top right answer and ask your teacher if they did accidently miss-type.
Step-by-step explanation:
The first thing to do in this equation is look at the exponents. When multiplying a variable (or any number equal to itself with the same exponent) you only have to add the exponent. So for a, you would add the exponents to get 0, so a to the power of 0 is 1, because any number to the power of 0 is 1. For b, we would add the 3 and 1. (When no exponenet is present in a number then it is 1, so for this I added 3 and 1). So it would be 4. The correct answer is
Answer:
Length of the given arc AB = 7.33 in.
Step-by-step explanation:
Formula to calculate the arc length is,
Arc length =
Where θ is the measure of central angle subtended by the arc.
And 'r' = radius of the circle
By substituting the values given in the formula,
Length of arc AB =
=
=
= 7.33 in.
Therefore, length of the given arc AB = 7.33 in.
Given:
Line a passes through (2, 10) and (4, 13).
Line b passes through (4, 9) and (6, 12).
Line c passes through (2, 10) and (4, 9).
To find:
Which of the lines, if any are perpendicular.
Solution:
If a line passes through two points, then the slope of line is
Line a passes through (2, 10) and (4, 13). So, slope of this line is
Line b passes through (4, 9) and (6, 12). So, slope of this line is
Line c passes through (2, 10) and (4,9). So, slope of this line is
Product of slopes of to perpendicular lines is -1.
Therefore, any of these lines are not perpendicular to each other.
