Answer:
B. The other solution to function 
is 
.
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form 
has solutions of the form:
, where both are complex if and only if 
.
Hence, if one solution of the quadratic function is 
, then the other solution is . The correct answer is B.
Answer:
20079.05 cm^2,
Step-by-step explanation:
Surface area of the box without the lid
= 90*42 + 2(90*34) + 2(42*34) = 12756.
Now find Surface area of the half cylinder:
The diameter of the 2 half circles = 42 so the radius = 21.
The area of the lid
= 2 + 1/2 π (21)^2 + π r * 90
= 7323,052
Total = 20079.052
Answer:
B) 2.849
Step-by-step explanation:
Given: 2.85 which is rounded to the nearest hundredth place.
To find the number, the thousandth place must be greater than or equal to 5.
Here 2.849 has the thousandth place greater than 5
When we round off 2.849 to the nearest hundredth place, we get
2.85
Therefore, answer is B) 2.849
Hope this will helpful.
Thank you.
