First, find angle ECD using tan^-1(6/4), we get angle as 56.31
Now by proportionate, angle ECD and angle EBA are equal.
Hence you can use tan to find AB i.e, AB = 18/tan(56.31)= 12
Therefore, AB = 12
Answer:
<em>Regan sold </em>
<em> gallons of lemonade</em>
Step-by-step explanation:
<u>Operations with Fractions</u>
Mark sold 
gallons of lemonade.
Regan sold 
as much lemonade as Mark
We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:
Now we multiply:
Regan sold gallons of lemonade
8 + 0 = 8: identity- addition (any number + 0= that number)
<span>a(b + c) = ab + ac: distributive (multiplying a on the left-hand side of the equation by the numbers in parenthesis gives you the right-hand side of the equation) </span>
<span>b + a = a + b: commutative- addition (numbers can be added in any order and still produce the same answer) </span>
<span>If 2 = x, then x = 2: symmetric (if a = b then b = a) </span>
<span>x(10) to be written 10x: commutative- multiplication (numbers can be multiplied in any order and still produce the same result)</span>
Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for <u>all</u> exponential functions, including this one.
lmk if im incorrect about anything, hope this helps :)
