Answer:
5
Step-by-step explanation:
Finding the extreme point :
Now,
f''( x ) at x = 1/3 and -1 is :
Therefore, it is maximum at x = -1 and minimum at x = 1/3 .
Hence, this is the required solution.
Answer:
The value of the z is 12 .
Step-by-step explanation:
Definition of vertically opposite angle .
Vertically opposite angles is defines angles opposite to each other when two lines cross eachother .
Thus
(5z + 8)° = (4z + 20)°
(5z + 8) = (4z + 20)
Open the bracket
5z + 8 = 4z + 20
5z - 4z = 20 -8
z = 12
Therefore the value of the z is 12 .
(4x+28)+(x+19)+(3x+13)=180
8x+60=180( combine like terms)
8x+60-60= 180-60
8x=120
8/8x=120/8
x=15
The missing angles are 88°, 34° and 58°
