Answer: f(3) =6

Step-by-step explanation:

Given: A sequence is defined by the recursive function

f(n+1)=f(n)-2

f(1)= 10

Then f(2) can be written as

f(2)=f(1+1)\\\\\Rightarrow f(2)=f(1)-2\\\\\Rightarrow f(2)=10-2\\\\\Rightarrow f(2)=8

Similarly, f(3) can be written as

f(3)=f(2+1)\\\\\Rightarrow f(3)=f(2)-2\\\\\Rightarrow f(3)=8-2\\\\\Rightarrow f(3)=6

Therefore, the value of f(3) =6.

Evaluate (-28) + 38 + (-12). EXPLAIN YOUR ANSWER, I KNOW IT’S -2, BUT WHY? How do I get -2? I am asking you to explain how you s
kipiarov [429]

Answer:

If the sign before the no. is same then they will get added and the resultant will have the same sign too.

Since before 28 and 12 , both of them have the negative sign , they will get added and the sign of their resultant will be negative too.

So , -28-12 = -40

Now, if the sign before the no.s are different then there will be subtraction, and the sign before the highest no. will be the sign of the resultant.

So,( -28)+38+(-12)

= -28+38-12

= -40+38

= -2

We know that 40> 38

sign before 40 is negative, therefore, their resultant i.e 2 will also get the negative sign

I hope this helps you...

2. What is the length of line segment CD? Show all your work! (4 points correct answer 6 points work shown)
pashok25 [27]
The answer 
to find the <span>length of line segment CD, we do the following method:
first, we must find the coordinates of vector CD
that is (xD-xC, yD-yC) =(-2-(-5), 1-(-3))=(-2+5, 1+3)=(3, 4)
next, computing the square root
CD=sqrt( 3² + 4²) = sqrt(9 +16) =sqrt(25)=5
so the value of CD=5</span>
