Answer:
I will only give answer if you gave 100 points . will you give ?
Graph A because it has two stationary points. That is, if you differentiate and put dy/dx as 0 there will be two answers
Answer:
The answer would be C.) 2.12
Answer: a = 0
Step-by-step explanation:
ok we got
. Our task is to choose a value for
so that "the tangent line to
at
passes through
."
Well
, and
. So our tangent line looks like this:
![y - 3 = (4 + a)(x - 1)](https://tex.z-dn.net/?f=y%20-%203%20%3D%20%284%20%2B%20a%29%28x%20-%201%29)
![y = 4x + ax - a - 1](https://tex.z-dn.net/?f=y%20%3D%204x%20%2B%20ax%20-%20a%20-%201)
We know this must contain the point
, so
![2a + 7 = 4(2) + a(2) - a - 1](https://tex.z-dn.net/?f=2a%20%2B%207%20%3D%204%282%29%20%2B%20a%282%29%20-%20a%20-%201)
![a = 8 - 7 - 1\\\\\boxed{a = 0}](https://tex.z-dn.net/?f=a%20%3D%208%20-%207%20-%201%5C%5C%5C%5C%5Cboxed%7Ba%20%3D%200%7D)
Answer:
6.5%
Step-by-step explanation:
=
= 0.935
0.935 -------> move the decimal point 2 places to the right ----> 93.5%
The man received 93.5%, meaning the broker received the rest.
100% - 93.5% = 6.5%
The brokers commission percentage was 6.5%
