Answer:
A. 8.3
B.18.7
C. 10.4
D. 1.04
Step-by-step explanation:
p(x) = 0.03x² + 0.56x + 6.35
A. Determination of p(3)
p(x) = 0.03x² + 0.56x + 6.35
x = 3
p(3) = 0.03(3)² + 0.56(3) + 6.35
p(3) = 0.03(9) + 1.68 + 6.35
p(3) = 0.27 + 1.68 + 6.35
p(3) = 8.3
B. Determination of p(13)
p(x) = 0.03x² + 0.56x + 6.35
x = 13
p(13) = 0.03(13)² + 0.56(13) + 6.35
p(13) = 0.03(169) + 7.28 + 6.35
p(13) = 5.07 + 7.28 + 6.35
p(13) = 18.7
C. Determination of p(13) – p(3)
From A and B above,
p(13) = 18.7
p(3) = 8.3
p(13) – p(3) = 18.7 – 8.3
p(13) – p(3) = 10.4
D. Determination of p(13) – p(3) / 13 – 3
From C above,
p(13) – p(3) = 10.4
p(13) – p(3) / 13 – 3 = 10.4/ 13 – 3
= 10.4 / 10
= 1.04
Answer:
48 cm²
Step-by-step explanation:
Area
= (6 x 2) + (10 - 6) x 9
= 12 + 36
= 48 cm²
Answer:
10+8=8+5+5
Step-by-step explanation:
Given that <span>Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.
The number of days it takes him to finish the book is given by 400 / 25 = 16 days.
In 0 days, he has 400 pages remaining and in 16 days he has 0 pages remaining.
Therefore, the graph that represents the situation is a</span><span>
graph in the first quadrant containing a line segment. The x axis is
labeled Days and the y axis is labeled Pages remaining. The endpoints of
the line segment are (0, 400) and (16, 0).</span>
Answer:
30
Step-by-step explanation:
(5+2)=7
9x3=27
2^3=8
7^2 - 27 + 8 (evaluate)
7^2=49
49 - 27 + 8 (calculate)
=30
