Answer:
This function is a quadratic.
Explanation:
If you sketch a graph, you will see the points form a U, representing a quadratic function.
The slope is defined as
So, we have the follwing equation:
2/11
there’s 2 R’s and 11 total so
possible outcomes/ overall outcomes
Answer: the answer is $456.76
Step-by-step explanation: All you have to do is subtract 38.90 from 495.66 and get your answer
What we know is that the sum of a triangle's internal angles are 180º, and a straight angle makes 180º.
first, we have to find the third internal angle(let's call it n) so that we can use it to find the exterior angle.
(3x + 20) + (4x + 5) + n = 180
simplify:
7x + 25 + n = 180
7x + n = 155
n = 155 - 7x
Now we can add it to the external angle to find x.
(155 - 7x) + (8x + 15) = 180
simplify:
170 + 8x - 7x = 180
170 + x = 180
x = 10
Now we can substitute it to the external angle.
8 x 10 + 15 = 95
the exterior angle is 95º.
