Roberto got $30 for his birthday. He decides to save that
shutvik [7]

After 10 weeks, the boys will have same amount in savings.

Step-by-step explanation:

Given,

Roberto already have $30.

Amount saved each week = $5

Let,

x be the number of weeks.

R(x) = 30+5x

Amount saved by Jack each week = $8

J(x) = 8x

For same amount, the functions will be equal.

R(x) = J(x)

30+5x=8x\\30=8x-5x\\30=3x\\3x=30

Dividing both sides by 3

\frac{3x}{3}=\frac{30}{3}\\x=10

After 10 weeks, the boys will have same amount in savings.

What is the equation of a line with a slope of 1/2 and a point (3, 1) on the line?
dezoksy [38]
Pattern of the equation = y = mx+b
Here, m = 1/2
So, y = 1/2x + b
Now, calculating for b,
1 = 1/2 * 3 + b
b = 1 - 3/2 = -1/2

So, equation will be: y = 1/2x - 1/2

Hope this helps!

Consider the universal relation r = {a, b, c, d, e, f, g, h, i, j} and the set of functional dependencies f = { {a, b } → {c}, {
nekit [7.7K]

Answer:

relation of FDs are {a, b, d, h}. From these all but {h}

seem plausibly part of keys. Calculating the closures of likely candidates gives:

{a, b} + = {a b, c, i}

{b, d} + = {b, d, e, f}

{a, d} + = {a, d, g, h, i, j}

{a, b, d} + = {a, b, c, d, e, f, g, h, i, j}  

decompose r into 2nf and then 3nf relations shown in attachment.                    

Step- by-Step Explanation

Explanation is given in the attachment.
