A P E X
Answer 2
Answer:

Answer:

Step-by-step explanation:

Note that the highest power of x is 5, which is odd.  Also note that the sign of the coefficient of x^5 is negative.  Hence, the graph begins in Quadrant II, generally decreasing as x increases, and ends in Quadrant IV.

IMPOSSIBLE MATH QUESTION(1+tan (1))(1+tan (2))(1+tan (3))(1+tan (4))...(1+tan (45))=?
find the value

Answers

well u can also do this without a calculator
take tan 1=tan(45-44)=(1-tan44)/(1+tan 44) 
then 
(1+tan1)=(1+ (1-tan44)/(1+tan 44))=(2)/(1+tan 44)
therefore similarly
(1+tan 1)(1+tan 2)...(1+tan 22)= (2)/(1+tan 44) (2)/(1+tan 43)(2)/(1+tan 42)..(2)/(1+tan 23)
= (2^(22))/((1+tan 44)(1+tan 43)(1+tan 42)...(1+tan 23))
then (1+tan 1)...(1+tan 45)= (2^(22))/((1+tan 44)(1+tan 43)(1+tan 42)...(1+tan 23))(1+tan 23)(1+tan 24)...(1+tan 45)
=2^(22)(1+tan45)=2^(23)=8388608
(1+tan 1)(1+ tan 2)...(1+tan 45)=(1+0.017455)(1+0.03492)...(1+1)=8388608.11

How do I solve x^2 - 2x - 63 = 0 by completing the square? Like they showed me how here but I'm not sure how this appiles if there's already a c and it doesn't factor into something that can be perfectly squared.

Answers

maybe you can try graphing it if the graph does not have any x-intercepts than it has no real roots
Basically you add a square after the 2x and then another square by the 63. Then, you use (b/2)^2 to put the answer in the square. Take b which is -2 in this case and divide it by 2.  (-2/2= -1), then you square your answer (-1^2= 1). so after doing those calcualtions take the 1 that you got and put it in the first square. For the second square you will put the negative of that number which is -1. Then once you multiply the numbers by what is in the square you'll factor it and get your answer. This is really complicated and you may need to watch a video to get it.

A coconut tree has 12 coconuts on it. If 25% of the coconuts fell to the ground, how many fell to the ground?

Answers

3 coconuts fell to the ground which is 25% of 12 coconuts.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A coconut tree has 12 coconuts on it.

25% of the coconuts fell to the ground.

∴ The no. of coconuts fell to the ground is 25% of 12 which is,

= (25/100)×12.

= 3

He Quotient of 10 and f increased by 2

Answers

The "quotient" of two numbers means you have to divide them.  So, the quotient of 10 and f is 10/f.  "Increased by" means plus, so you must add 2 to 10/f.  The equation you get is (10/f)+2.  (Note: you put this in parentheses so that people know to divide 10 and f first.)

Answer: (10/f)+2
