Answer:
Step-by-step explanation:
Without the variable x, your "f(x) = 3(18)*" is not a function. If you meant
f(x) = 3(18)^x, then the domain is "the set of all real numbers," and the range is (0, infinity).
the initial value is 3: f(0) = 3(18)^0 = 3(1) = 3
Answer: use socratic you take a picture of the problem and it does it.
<u>Question </u>
Select the three equations that this diagram could represent.
<u> </u>
<u>Answer</u>
<em>Well, we first have to find out what the diagram says.</em>
<em>So what the diagram says is that 18 + 18 + 18 = 54.</em>
<em>Given this information, we have to figure what other answers = 54.</em>
<em>Therefore the answers are </em>
(A) 18 * 3 = 54.
(D) 54/18 = 3
(E) 54/3 =18
Lines that overlap each other opposite like a T or +
Answer:
A = 222 units^2
Step-by-step explanation:
To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB (Call this point E). Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units. Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:
(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.
The area of this trapezoid is
A = (average vertical length)(width), which here is:
(21 + 16) units
A = --------------------- * (12 units), which simplifies to:
2
A = (37/2 units)(12 units) = A = 37*6 units = A = 222 units^2
