This seems an exponential function.
Once you state that the function is exponential you can write is this form:
f(x) = A * b^x.
Then you need the y-intercept (i.e. x = 0) to find A
f(0) = A * b^0 = A
Once you have A, you can use the ordered pair (3,1) to find b
f(1) = A*b^2 = A*b = 3 => b = 3/A.
With that procedure you can find the function that represents the given graph.
Suppse the y-intercep is 0.1
Then f(0) = A = 0.1
And b = 3 / A = 3/0.1 = 30
And the function is f(x) = 0.1* 30^x
Answer: Line DE is the adjacent while line EF is the opposite.
Step-by-step explanation: This is a right angled triangle and the reference angle has been marked at point D. If you drew a line from that angle it would touch the triangle at line line EF. It’s facing the reference angle and that’s why it’s called the “opposite.”
The line that lies between the reference angle and the right angle is called the adjacent and that’s line DE in this triangle. The hypotenuse has already been identified for you, and that’s the line that’s opposite the right angle (it’s always the longest side).
**Please note that the opposite and adjacent ALWAYS depends on where the reference angle is positioned.
Let's call the number of members x. We have x + 10 people who each pay $5, resulting in a sum of $600.
5(x+10) = 600
5x + 50 = 600
5x = 550
x = 110
Answer:
Step-by-step explanation:
We have the two points (4,0) and (0,-2)
Find the slope
y-intercept is -2
Answer:
7:5 is the same as 21: 15
Step-by-step explanation:
21/7 = 3 and 3*5=15
i divided 21 by 7 to see how many times it was multiplied to get there, so i could do the same thing to the 5
I hope this helps :)
