Answer:
im not sure...cuz it says 50%
its either 11.625 or 5.8125
it is the 1st one if the question means all average but if not PROBABLY only PROBABLY the right one
Step-by-step explanation:
I added all the hours together and divided it by 24 to get 11.625 but if the ans is 5.1825 ill divide 11.625 over 2
You would get $26,880.
0.07*4000= 280; so $280 are added every month
There are 96 months in 8 years, so multiply 280*96 which =26,880
The possible problems of using graphs to find roots are:
- Having complex roots.
- Having irrational roots.
<h3>How to find the roots of a quadratic function with a graph?</h3>
First, the roots of a quadratic function are the values of x such that:
a*x^2 + b*x + c = 0
To find the roots using a graph, we need to see at which values of x does the graph of the parabola intercepts the horizontal axis.
<h3>What are the possible problems with this method?</h3>
There are two, the first one is having irrational roots, in that case, an analytical or numerical approach will give us a better estimation of the roots. Finding irrational values by looking at the intercepts of the graph can be really hard, so in these cases using the graph to find the roots is not the best option.
The other problem is if we <u>don't have real roots</u>, this means that the graph never does intercept the horizontal axis. In these cases, we have complex roots, that only can be obtained if we solve the problem analytically.

Answer:
317°
Step-by-step explanation:
The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.
(7x +1)° +90° +(9x -7)° = 180°
16x = 96 . . . . . divide by °, subtract 84
x = 6 . . . . . . . . divide by 16
Then angle AOD is ...
(7·6 +1)° = 43°
Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.
arc ACD = 317°
