Answer:
b. 
Step-by-step explanation:
The graph can be divided into 4 regions.
Region 1 is for 
Region 2 is for 
Region 3 is for 
Region 4 is for 
So, for the region 1, the values of 
goes on decreasing with increasing 
. Therefore, the function is decreasing in the interval 
.
Now, for the region 2, the values of increases with increasing . So, the function is increasing in the interval 
.
For the region 3, the the values of goes on decreasing with increasing . Therefore, the function is decreasing in the interval 
.
Now, for the region 4, the values of increases with increasing . So, the function is increasing in the interval 
.
Therefore, regions 2 and 4 are the regions when the function is increasing.
Hence, the correct option is b.
Answer:
31
Step-by-step explanation:
Here the trick is to perform the indicated operations in the correct order. Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.
Doing the work inside parentheses first:
(3 × 22) ÷ 6 + [28 – (4)2] => (66) ÷ 6 + [28 - 8], or
(66) ÷ 6 + [28 - 8] => 11 + [20], or 31
Answer: D and A
Step-by-step explanation:
Just took the apex quiz and it’s right
As soon as I read this, the words "law of cosines" popped
into my head. I don't have a good intuitive feeling for the
law of cosines, but I went and looked it up (you probably
could have done that), and I found that it's exactly what
you need for this problem.
The "law of cosines" relates the lengths of the sides of any
triangle to the cosine of one of its angles ... just what we need,
since we know all the sides, and we want to find one of the angles.
To find angle-B, the law of cosines says
b² = a² + c² - 2 a c cosine(B)
B = angle-B
b = the side opposite angle-B = 1.4
a, c = the other 2 sides = 1 and 1.9
(1.4)² = (1)² + (1.9)² - (2 x 1 x 1.9) cos(B)
1.96 = (1) + (3.61) - (3.8) cos(B)
Add 3.8 cos(B) from each side:
1.96 + 3.8 cos(B) = 4.61
Subtract 1.96 from each side:
3.8 cos(B) = 2.65
Divide each side by 3.8 :
cos(B) = 0.69737 (rounded)
Whipping out the
trusty calculator:
B = the angle whose cosine is 0.69737
= 45.784° .
Now, for the first time, I'll take a deep breath, then hold it
while I look back at the question and see whether this is
anywhere near one of the choices ...
By gosh ! Choice 'B' is 45.8° ! yay !
I'll bet that's it !
