Answer 1

Answer:

By using proportions, it is found that the better buy would be d. Brand D: $1.84 for 16 ounces.

What is a proportion?

A proportion is defined as the fraction of a total amount.

In the given problem, the better buy will be given by the lowest ratio of price to ounces.

Hence:

1.25/10 = 0.125

1.47/12 = 0.1225

1.68/14 = 0.12

1.84/16 = 0.115

Hence brand D is the better buy.

Geoff planted dahlias in his garden. Dahlias have bulbs that divide and reproduce underground. In the first year, Geoff’s garden produced 8 bulbs. In the second year, it produced 16 bulbs, and in the third year it produced 32 bulbs. If this pattern continues, how many bulbs should Geoff expect in the sixth year?A. 64
B. 512
C. 128
D. 256

1st = 8, 2nd = 16, 3rd = 32, doubling each time so 4th = 64, 5th = 128,

6th = 256

Someone you know is planning a wedding. They have still have decide on the place of the reception, the DJ, and the caterer. They have narrowed it down to 2 reception halls, 3 DJs, and 2 catering companies. How many arrangements are possible for this wedding?

Answers

So essentially, we have a choice of :

2 reception halls
3 DJs
2 catering companies.

In order to find the number of arrangements, you need to multiply those : 2*3*2=12- So they have 12 arrangements.

why?

Imagine those 3 Djs- they are three arrangements.
Now, they can play in one or the other hall -so in total it's 3 Djs in one hall and 3 in the other -that's 6.

And all of those 6 possibilities can be catered by one or the other company- making the possibilities twice as many, so it's 12 in total!

Given a polynomial f(x), if (x - 2) is a factor, what else must be true?f(2) = 0

f(-2) = 0

f(0) = 2

f(0) = -2

Answers

If a number is a root of a polynomial, then we substitute the number to x of the polynomial, the answer or y is equal to zero. Hence, in this situation, if (x - 2) is a factor, the root is equal to 2. This means then that upon substituting 2 to the function, y is equal to zero. Answer then is A. f(2) = 0
