Answer: 5(x +1.5)^2
10(x +1)^2
1/4(x +2)^2
3(x +5/6)^2
Explanation: When your desired form is expanded, it becomes ...
a(x +b)^2 = a(x^2 +2bx +b^2) = ax^2 +2abx +ab^2
This tells you the overall factor (a) is the leading coefficient of the given trinomial. Factoring that out, you can find b as the root of the remaining constant.
a) 5x^2 +15x +11.25 = 5(x^2 +3x +2.25) = 5(x +1.5)^2
b) 10x^2 +20x +10 = 10(x^2 +2x +1) = 10(x +1)^2
c) 1/4x^2 +x +1 = 1/4(x^2 +4x +4) = 1/4(x +2)^2
d) 3x^2 +5x +25/12 = 3(x^2 +5/3x +25/36) = 3(x +5/6)^2
The answer is true. They work in conjunction with the bairn endothelial
cells to create a semi-permeable blood-brain
barrier with tight junctions that only allows certain elements to pass into the brain. They achieve this through astrocytic endfeet
in addition to the thick basement membrane.
The producers in a food web. Following the 10% rule, not only does the top carnivore get the least amount of calories from the food web, but is subject to dying based on one animal dying out, affecting the rest of the food chain. However, because the producers are autotrophic, they only rely on the sun, and therefore, are more likely to survive since they don't rely on any other living organism.
Answer:
A. will not change from generation to generation.
Explanation:
For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:
-The population is large enough.
-Individuals of the population exhibit random mating
.
-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.
Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".
