We are tasked to solve for the smallest angle using the law of cosines given that the three sides of the triangle are 4,5 and 6.
a=4 , b=5, c=6
Angle 1:
cosA = 5² + 6² - 4² / 2*5*6
A=41.41°
Angle 2:
cos B = 4²+6² -5² /2*4*6
B= 55.77°
Angle C:
C = 180° - 41.41° - 55.77°
C = 82.82°
The smallest angle is A which is equal to 41.41°.
Answer:
Lanier Lanier mean a stright line
All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.
This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x
Then combine like terms and line all the values in order from greatest exponent value to least to get
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6
Hope this helped :)
Answer: 0.8137
Step-by-step explanation:
As per given , we have
Sample size : n= 47
Let 
be the sample mean o.
Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :
[∵ 
]
[By using p-value calculator]
Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137
Answer:
B and C
(I'm not sure if b and e are supposed to be the same though) if they are then, b, c, and e
