Answer:
x = -5/2
Step-by-step explanation:
Answer: f(0)= -4, f(5)= 15, f(-3)= -7
Step-by-step explanation:
0 < 1, so plug into x-4. 0-4=-4
5> 1, so plug into 3(x). 3*5=15
-3<1, so plug into x-4. -3-4=-3+(-4)= -7
<span>The domain of the function can be obtained by pluging the values of the range into f(x), i.e domain = {k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64} = {k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}. Solving the two quadratic equations, we have that the range is {-9, -6, 4, 7}.I hope that my answer is helpful! Let me know if you need something more :)</span>
Answer:
10. 48 degrees 11. Use explanation below. 12. 25 degrees 13.Use explanation below. 14. 63 degrees 15. Use explanation below. 16. 130.5 17. A. 48 degrees B. 90 degrees and C. 42 degrees 18. Explain
Step-by-step explanation:
10. All triangles angles add up to 180 degrees, so 100+32=132 and 180-132=48
11. Use the explanation above.
12. Using the rule above 88+57=145 and 180-145= 25
13. Use explanation above.
14. Add the two answers from 10 and 12. 48+25= 63
15. Use explanation above.
16. Using the triangle 180 degrees rule add 90 degrees (Angle a is a right angle which is always 90 degrees) to 40.5 degrees. 40.5 + 90= 130.5
17. You have angle A (48) angle B is a right angle aka 90 degrees and using the rule 90+ 48= 138 and 180-138= 42
18. I think you can explain it now (I hope)
