f(x) = 5x − 1 and g(x) = 2x^2 + 1
(f × g)(x) = (5x − 1)(2x^2 + 1)
(f × g)(x) = 10x^3 - 2x^2 + 5x - 1
Substitute x = - 3
(f × g)(-3) = 10(-3)^3 - 2(-3)^2 + 5(-3) - 1
(f × g)(-3) = 10(-27) - 2(9) -15 - 1
(f × g)(-3) =-270 - 18 - 16
(f × g)(-3) = -236
Answer
- 236
Answer:
Plants are restrictive to flow of eroding agents, bind soil in their roots.
Step-by-step explanation:
Soil Erosion is the wearing away of the topmost fertile layer of soil. Topsoil gets eroded mainly due to wind, water agents.
Plants help to prevent soil from erosion in following ways :
- Plants act as restriction to the speed of air & water, which are the main soil erosion agents. It also lets rain water get soaked into the ground water.
- Plants roots also bind the soil tightly, & make soil stronger to be eroded by erosive agents - water, air. Eg : Shrubs , trees, grass & ground are important soil erosion preventive plants, because of their extensive root systems.

4(6x+4)-5(3x-6) First you distribute 24x+16-15x+30 then you add like terms so 24x-15x is 9x. 16+30 is 46. So the answer is 9x+46
Answer:
Step-by-step explanation:
Urn has 3 green and 4 yellow
we choose 2 balls randomly
so samples space for this selection is
![\left [ \left ( Y,G\right ),\left ( G,Y\right ),\left ( G,G\right ),\left ( Y,Y\right )\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%20%5Cleft%20%28%20Y%2CG%5Cright%20%29%2C%5Cleft%20%28%20G%2CY%5Cright%20%29%2C%5Cleft%20%28%20G%2CG%5Cright%20%29%2C%5Cleft%20%28%20Y%2CY%5Cright%20%29%5Cright%20%5D)
Event A is choosing differently colored ball form sample space
P(A)=Probability of event (G,Y)+Probability of event (Y,G)
