Split the second term in 2x^2 - x - 6 into two terms
2x^2 + 3x - 4x - 6
Factor out common terms in the first two terms, then in the last two terms
x(2x + 3) - 2(2x + 3)
Factor out the common term 2x + 3
<u>(2x + 3)(x - 2) </u>
Answer:
The relation is not a function.
Step-by-step explanation:
The x-values of the relation are repetitive, making it not a function.
Answer:
2.4
Step-by-step explanation:
Irrational as 0.75 x 0.75 x 3.14......
We are given with the rate of change of the base, db/dt equal to 1 ft/ sec and the rate of change of the height of the triangle, dh/dt equal to 2 ft/sec. b is 10 ft and h is 70 ft. Area of triangle is equal to A= 0.5 bh The rate of change of the area is equal to dA/dt = 0.5 b dh/dt + 0.5 h db/dt. Substituting, dA= 0.5*10*2 + 0.5*70 * 1 equal to 45 ft2 / sec.
