Is there a direct proportion in 3y=1/2x? if there is one, what is the constant of proportionality?

kipiarov [429]

A direct proportion is any equation where y = mx+b. (i.e., a linear equation)

Each side of 3y = 1/2x can be divided by 3 to get y = 1/6x, satisfying the condition of y = mx+b. (b=0)

In this case, the constant of proportionality would be 1/6.

PLEASE ANSWER FAST What is the average of the following two numbers? 5.67 x 10^-21 and 7.24 x 10^-19

adell [148]

Answer: The average of two numbers is $3.64835\times 10^{-19}$ .

Explanation:

The first term is,

$5.67\times10^{-21}$

The second term is,

$7.24\times10^{-19}$

Average formula is,

$Average=\frac{\text{Sum of observations}}{\text{Number of observations}}$

$Average=\frac{5.67\times10^{-21}+7.24\times10^{-19}}{2}$

$Average=\frac{5.67\times 10^{-2}\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{0.0567\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{(0.0567+7.24)\times10^{-19}}{2}$

$Average=\frac{(7.2967)\times10^{-19}}{2}$

$Average=3.64835\times10^{-19}$

Therefore, the average of two numbers is $3.64835\times 10^{-19}$ .

VLD [36.1K]

Answer:

The common ratio is 5 and the 5th term is 1250

Step-by-step explanation:

The common ratio is given by

r=U(2)/U (1)

=10/2

The fifth term

U (n)=ar^n-1

U(5)=2(5)^5-1

=2×5^4

=2×625

=1250
