You can re-write this quotient this way :

\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\

What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))

In other word we must find x so that :

\frac{28(x-1)}{8x^{2}}\geq 0

at the end we get

28(x-1) ≥ 0

28x - 28 ≥ 0

28x ≥ 28

x ≥ 1

So the answer is B, x ≥ 1

Write the equation of the line in slope-intercept form that passes through the points
Bogdan [553]

Answer:

y = - 5x + 8

Step-by-step explanation:

(-8,48) and (-1,13)

m = (48-13)/(-8/- - 1) = 35/- 7

m = -5

y - 13 = - 5(x - - 1)

y - 13 = - 5(x+1)

y - 13 = -5x - 5

y = - 5x - 5 + 13

y = - 5x + 8

Population growth the population of knoxville is 500,000 and is increasing at the rate of 3.75% each year. approximately when wi
Shalnov [3]
Current population = 500,000
Populaton is
500,000 * (1.0375) after 1 year
500,000 * (1.0375)² after 2 years 
...
500,000 * (1.0375)ˣ after x years

Therefore when the population reaches a million,
500,000 * (1.0375)ˣ = 1,000,000
1.0375ˣ = 2
x ln(1.0375) = ln(2)
x = ln(2) / ln(1.0375) = 18.83 years

Answer:  18.8 years, or approximately 19 years.

What are two equivalent ratios for 8/10?
Varvara68 [4.7K]
To find this, multiply both the numerator and denominator by the same number. For example, 8 x 8 =64, and 10 x 8=80, so 64/80 would be an example of an equivalent ratio. Others could be 16/20 or 48/60. Hope this helps.

What’s a constant Proportionality
irina1246 [14]
In mathematics, two variables areproportional if there is always aconstant ratio between them. Theconstant is called the coefficient ofproportionality or proportionality constant. ... x and y are directlyproportional if the ratio yx is constant.

In other words, the constant of proportionality is also the slope, **m**, rate of change, etc.
