which of the following best describes 4^2/3? a. sq root of 16, b. cube root of 4, c. sq root of four, d. cube root of 16
son4ous [18]

Answer: D) cube root of 16

================================================

Explanation:

The rule we use is

x^{m/n} = \sqrt[n]{x^m}

In this case, x = 4, m = 2 and n = 3.

So,

x^{m/n} = \sqrt[n]{x^m}\\\\\\4^{2/3} = \sqrt[3]{4^2}\\\\\\4^{2/3} = \sqrt[3]{16}\\\\\\

Showing that the original expression turns into the cube root of 16.

What is the perpendicular distance from the line y= 2x-3 to the point (8,3)
Liula [17]
Find the perpendicular line then find the intersection then find the point

perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1

y=mx+b
m=slope
y=2x-3
2 is slope

2 times what=-1
what=-1/2


the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7

find intersection
at (4,5)
distance bwetweeen (8,3) and (4,5)
D=\sqrt{(8-4)^2+(3-5)^2}
D=\sqrt{(4)^2+(-2)^2}
D=\sqrt{16+4}
D=\sqrt{20}
D=2√5
distance= 2√5

In a spreadsheet create a function that generates for any value x the corresponding value y when y = 10x 7. what is the value y
bezimeni [28]

The value of y when the value of x is 8 is 87

<h3>Function and values</h3>

Functions are equation expressed in terms of variables. Given the expression below;

y = 10x + 7

If the value of x is 8, then on substituting, we will have:

y = 10(8) + 7

y = 80 + 7

Simplify

y = 87

Hence the value of y when the value of x is 8 is 87
