Step-by-step explanation:
12.5
Split the second term in 6x^2 + x - 2 into two terms
6x^3 + 4x - 3x - 2/3x^2 + 14x + 8
Factor out the common terms in the first two term, then in the last two terms
2x(3x + 2) - (3x + 2)/3x^2 + 14x + 8
Factor out the common term 3x + 2
(3x + 2)(2x - 1)/3x^2 + 14x + 8
Split the second term in 3x^2 + 14x + 8 into two terms
(3x + 2)(2x - 1)/3x^2 + 12x + 2x + 8
Factor out common terms in the first two terms, then in the last two terms
(3x + 2)(2x - 1)/3x(x + 4) + 2(x + 4)
Factor out the common term x + 4
(3x + 2)(2x - 1)/(x + 4)(3x + 2)
Cancel 3x + 2
<u>2x - 1/x + 4</u>
Y-INT IS $100 since its the starting point. 20 is the slope so make graph counting by 20’s
Answer:
0.5 cm per 10 degrees
0.05 cm per one degree.
Step-by-step explanation:
For 30 degrees the bridge has a gap of 1.4 cm
For 40 degrees the bridge has a gap of 0.9 cm
The bridge expanded
1.4 cm - 0.9 cm = 0.5 cm per 10 degrees
Or, likewise
0.5/10 = 0.05 cm per one degree.
This means that for each degree that the temperature increases, the bridge will expand 0.05 cm
