Mathematics
1 answer:
atroni [7]3 years ago
7 0

Answer:

The expression is not completely factored.

Step-by-step explanation:

The expression of {x}^{2} - 4 can be broken up into two binomials:

[x - 2][x + 2]

Together, you have this:

3[x - 2][x + 2]

** There is alot of missing information to this question, but at least you know how to work this out.

What is Segregation of alleles?

  • Allele pairs (several features of the same gene) are segregated during meiosis so that they can be transferred selectively to different gametes.
  • During meiosis, maternal and paternal alleles separate.

What is genotype vs phenotype ?

  • Genotype: An organism's genetic makeup.
  • Phenotype. physical characteristic that arises within an organism as a result of its genotype. Probability law.
  • Genotype - the set of alleles that make up an organism.

How does genotype influence phenotype ?

  • The alleles you have for a specific gene or collection of genes are referred to as your genotype.
  • The physical attribute itself, or phenotype, can be affected by both genotype and environmental variables.

The washer in the image has an inner diameter of 1/4 inch. The outer diameter measures 3/4 inch, and the washer is 1/4 inch thic
Talja [164]

Answer:

  0.14 lb . . .  closest choice is 0.11 lb

Step-by-step explanation:

The inside and outside radii are 1/8 in and 3/8 in, respectively. Then the area of the top of the washer is ...

  A = π(R² -r²) = π((3/8)² -(1/8)²) = π(9/64 -1/64) = π/8 . . . square inches

The height of the stack of 5 washers will be 5×(1/4 in) = 5/4 in. So, the volume of material in the stack of washers is ...

  V = Bh = (π/8)(5/4) = 5π/32 . . . cubic inches

The weight of material is the product of volume and density, so is ...

  W = (5π/32 in³)(0.285 lb/in³) ≈ 0.1399 lb ≈ 0.14 lb

_____

<em>Comment on the question</em>

Since this answer does not correspond to any of the offered choices, we suggest you ask your teacher to work this out for you. We suspect they will have difficulty justifying any of the answer choices shown here. (0.11 lb corresponds to 4 washers, not 5.)

How much fabric is needed to create the lateral faces of the tent?
jek_recluse [69]
Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40

40+89.6=129.6

the area of the bottom is 7*8=56

the total area is 129.6+56=185.6

I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice. 
I'd suggest 185.6, the total surface area.
