Answer:
Area = 200x - x², Max area is 10000m² with dimensions 100m × 100m
Step-by-step explanation:
Total fencing = perimeter
Let length of the sides be x and y,
2(x + y) = 400
x + y = 200
y = 200 - x
Area = x × y
= x(200 - x)
Area = 200x - x²
For max area, convert area into the completed square form
-(x² - 200x)
-(x² -2(x)(100) + 100² - 100²)
-[(x - 100)² - 10000]
-(x - 100)² + 10000
Max area is 10000 m²
Because the least value of (x - 100)² is 0.
That too when x = 100
When x = 100,
y = 200 - x = 200 - 100 = 100
Dimensions are 100m × 100m
If tall is completely dominant over short, then the mother's genotype is either TT or Tt. The father is short so his genotype is tt.
Crossing TT with tt produces only heterzygous offspring with genotype Tt. Then the genotypic and phenotypic ratios are 0 TT : 1 Tt : 0 tt and 1 tall : 0 short, respectively. As percentages, these would
• geno: 0% TT : 100% Tt : 0% tt
• pheno: 100% tall : 0% short
Crossing Tt with tt on the other hand produces offspring with genotype either Tt or tt with equal probability, so that the geno and pheno ratios are 0 TT : 1 Tt : 1 tt and 1 tall : 1 short. As percentages,
• geno: 0% TT : 50% Tt : 50% tt
• pheno: 50% tall : 50% short
Answer:
9.055
Step-by-step explanation:
Combine like terms.
3a + 2a = 5a
5a - 2b.
Plug in the values for a and b.
5(2) - 2(3)
10 - 6 = 4
Answer is B.
