Y is directly proportional to x.y is 30 and x is 6 work out the equation linking x and y

kap26 [50]

Answer:

y = 5x

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportionality

To find k use the condition that y = 30 when x = 6

k = $\frac{y}{x}$ = $\frac{30}{6}$ = 5

y = 5x ← equation of proportion

Identify the type of sequence shown in the table below and select the appropriate response. (5 points) n f(n) 1 540 2 500 3 460

Svetradugi [14.3K]

$\bf \begin{array}{ccll}
n&f(n)\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&540\\
2&\stackrel{540-40}{500}\\\\
3&\stackrel{500-40}{460}\\\\
4&\stackrel{460-40}{420}\\\\
5&\stackrel{420-40}{380}
\end{array}$

notice, the next term is obtained by subtracting 40 from the "current" one, meaning, is an arithmetic sequence, with a "common difference" of -40.

Which expression is equivalent to 10√5

mixer [17]

Answer:

A. √500

Step-by-step explanation:

Since 500 = 5·100 = 5·10² you can move the 10² out of the √ as 10.

Hence 10√5 = √500

So we're using these rules:

√a·b = √a·√b

and of course

√a² = a (a>0)
