Answer:
1/4
Step-by-step explanation:
The slope of a line is the steepness of a line.
The slope of a perpendicular line is always the negative reciprocal of the slope of the line it is perpendicular with.
Since line C has a slope of -4, the negative reciprocal of that is 1/4.
Reciprocals are two numbers that multiply together to get 1.
For example, -1/4*-4/1=1
Therefore the negative recipricol is 1/4
The cross of YyRr will produce 16 distinct genotypes.
If the two alleles are far enough on the same chromosome, then the Y and R alleles will be distributed independently of one another, so that the genotypic ratio among each allele would be 1:2:1 (YY:Yy:yy, and similarly for the R allele). Then the dihybrid cross will yield a genotypic ratio of 1:2:1:2:4:2:1:2:1 (YYRR:YYRr:YYrr:YyRR:YyRr:Yyrr:yyRR:yyRr:yyrr).
Now, assuming perfect Mendelian inheritance (complete dominance), the phenotypes exhibited by YY and Yy will be considered equivalent, and similarly for RR and Rr, so the phenotypic ratio would be 9:3:3:1 (YR:Yr:yR:yr).
Answer:
B) Domain: -2≤x≤2 Range: -2≤x≤3
Step-by-step explanation:
The domain is the x-values, in this case all the numbers between -2 and 2. The range is the y-values, which are the numbers between -2 and 3. So the answer is
B) Domain: -2≤x≤2
Range: -2≤x≤3
