Answer:
E. (The function is exponetial)
Step-by-step explanation:
We look at the output values and subtract them from their previous value to see it's slope.
6-2 = 4
12-6 = 6
4 ≠ 6, meaning that the slope is not constant.
4 < 6, meaning that the slope is increasing, meaning the function is exponential.
The greatest possible error is 0.5lb.
The GPE is one half of one unit, no matter which unit you're using or the margin of error you have.
Since we are using pounds in this case, the GPE is 0.5 pounds.
Answer:
78º
Step-by-step explanation:
<u>Note</u> : -
In mathematics, the reference angle is defined as the acute angle and it is measuring less than 90 degrees. It is always the smallest angle, and it makes the terminal side of an angle with the
x - axis.
<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>1</u> : -
Find where 192º lies in which quadrant.
192º lies in 3rd quadrant ( between
180º and 270º )
<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>2</u> : -
Subtract : 270 - 192
270 - 192 = 78º
( Since, 192º is greater than 180º, is subtracted from 270º )
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u> : -
78º is the reference angle for 192º.
Substitute the number for the appropriate variables and solve
(ab)^2
(4×3)^2
(12)^2
12×12
144
Your answer is B.144
Given:
f(x) is an exponential function.

To find:
The value of f(6.5).
Solution:
Let the exponential function is
...(i)
Where, a is the initial value and b is the growth factor.
We have,
. So, put x=-3.5 and f(x)=25 in (i).
...(ii)
We have,
. So, put x=6 and f(x)=33 in (i).
...(iii)
On dividing (iii) by (ii), we get





Putting b=1.03 in (iii), we get




Putting a=27.63 and b=1.03 in (i), we get

Therefore, the required exponential function is
.
