11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)
0.01 that should be your answer
This would be 4cm... Since all the sides are equal and you have the distance between CB you can calculate the distance of all other sides
Answer:
f(x) = -x is a reflection in the x-axis of f(x) = x
Step-by-step explanation:
f(x) = -x is a reflection in the x-axis of f(x) = x
By applying the definition of <em>exponential</em> function, we find that the function f(x) = 3 · 2ˣ match with the graph of the picture. (Correct choice: A)
<h3>What is the equation behind the exponential curve seen in the graph?</h3>
In this question we have the graph of a <em>exponential</em> function, whose expression have to be found based on the definition of <em>exponential</em> function:
y = a · bˣ (1)
Where:
- a - Initial value of the exponetial function.
- b - Base of the exponential function.
- x - Independent variable
- y - Dependent variable
Now we find the values for a and b:
Initial value (x = 0, y = 3)
3 = a · b⁰
a = 3
Base of the exponential function (x = 1, a = 3, y = 6)
6 = 3 · a
a = 6 / 3
a = 2
By applying the definition of <em>exponential</em> function, we find that the function f(x) = 3 · 2ˣ match with the graph of the picture. (Correct choice: A)
