Answer:
the angles s and r are supplementary so 180 - 40 = 140
Step-by-step explanation:
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9
vertex is at (5,-9)
the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever
verrtex is at (5,-9)
Answer:

Answer:
the answer is she had $4.40 left.
Step-by-step explanation:
1) 40x1.50=<u>60</u> 2) 40x0.89= <u>35.6</u> 3) 60+35.6= <u>95.6</u> 4) 100- 95.6= <u>$4.4</u> I hope this helps if not sorry. :)
Question: solve for r: 6 ^ (2r) = 800
Answer: 1.87
Step-by-step explanation:
6 ^ (2r) = 800
log(6 ^ (2r)) = log(800)
2r log(6) = log(800)
r = log(800) / (2 log(6))
r = 1.86537641979
round
r = 1.87
log can be any logarithm function.
6^(2×1.86) = 784.734328546
6^(2×1.87) = 813.365367336
