You can put 400/100 to get the fraction 4/1 or 4, it is not a mixed number though. So the final answer is 4
Answer:
$360
Step-by-step explanation:
I am pretty sure this is the answer i am not that sure. But $9,000 at 8% is 760
and 360 is half of 760
Answer:
125°
Step-by-step explanation:
Angle NMP and angle LMK are equal as they are vertical angles!
When straight lines intersect one another, the angles are the same.
Answer:
f(-3) = -20
Step-by-step explanation:
We observe that the given x-values are 3 units apart, and that the x-value we're concerned with is also 3 units from the first of those given. So, a simple way to work this is to consider the sequence for x = 6, 3, 0, -3. The corresponding sequence of f(x) values is ...
34, 10, -8, ?
The first differences of these numbers are ...
10 -34 = -24
-8 -10 = -18
And the second difference is ...
-18 -(-24) = 6
For a quadratic function, second differences are constant. This means the next first-difference will be ...
? -(-8) = -18 +6
? = -12 -8 = -20
The value of the function at x=-3 is -20.

The attachment shows using a graphing calculator to do a quadratic regression on the given points. The graph can then be used to find the point of interest. There are algebraic ways to do this, too, but they are somewhat more complicated than the 5 addition/subtraction operations we needed to find the solution. (Had the required x-value been different, we might have chosen a different approach.)
