what is your question then?
Answer:
d=12
Step-by-step explanation:
15-d/4+2=1/2
15-d/6=1/2
2(15-d)=6
30-2d=6
30-6=2d
24=2d
d=12
Answer:
two real roots
Step-by-step explanation:
y = -2x^2 + 9x - 7
This is in the form
ax^2 +bx+c
a = -2 b = 9 c = -7
The discriminant is
b^2 -4ac
(9)^2 - 4(-2) (-7)
81 - 56
25
Since the discriminant is greater than zero, there are two real roots
Answer:
The medium-sized can is the cheaper by the oz, and is $0.005 per oz. cheaper.
Step-by-step explanation:
Medium can: $0.92/(46 oz) = $0.020/oz
Large can: $3.60 / (144 oz) = $0.025/oz
Surprisingly, the medium can price per oz. is lower than that of the large can. The difference is $0.005 per oz.
Answer:
The phenotypic ratios are the ratios of visible characteristics. The genotypic ratios are the ratios of gene combinations in the offspring, and these are not always distinguishable in the phenotypes.
