F(4) value is 6.
I believe it would work like this:
f(x) is being turned into f(4), so 4 would equal x. Put 4 into the equation 3x-6, and you get 12-6, which gives you 6. So the value of f(4) is 6. I hope this helps!
Answer:
- 508
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus
= - 28 + (- 6 × 80) = - 28 - 480 = - 508
Answer:
11. x = -16
12. k = 6
13. x = -19
14. x = -6
15. x = -20
16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?
17. x = 19
18. n = -10
19. b = 11
20. n = 4
21. r = -6
22. n = -4
Again super sorry about question 16 :(
Area of a semicircle =
r² / 2
r= 5/2 = 2.5
So: A= 3.14 x 2.5² / 2 A = 9.8125 so rounding to the nearest hundredth is A=9.81
I got it now!
(hold your applause)
Area of the rectangle is 12 to the power of 2 (or you can just say squared) and that equals 144cm squared
the area of the circle is pi radius squared (in this case radius is 3) and it equals 9 pi squared
to get the shaded area that is last over with the circles removed you would have to do (144)-(9pi) (this part is unachievable without a calculator that has the pi symbol to fill in instead of just writing 3.14) and after you get the answer of that which is 115.725666118
and that amount you must do the same with so it would be
(115.725666118)-(9pi) and that equals ...............
87.4513322357
(you may now applaud)
