The equation y = 14x/z represents _____________ variation.

SpyIntel [72]

Answer:

D. joint variation

Step-by-step explanation:

y = 14x/z

y is directly proportional to x and inversely proportional to y

Constant of proportionality = 14

Direct variation is given as

y = kx

Where, k = constant of proportionality

Inverse variation is given as

y = k/z

Where, k = constant of proportionality

When they are jointly combined

y = kx/z

Find the distance between the pair of points. give an exact answer, and, where appropiate, and apporximation to two decimal plac

atroni [7]

Distance Formula: $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
Product rule of radicals: √ab = √a x √b

Using our two points, we can solve for the distance as such:

$\sqrt{(4-(-6))^2+(3-(-1))^2}\\ \sqrt{(10)^2+(4)^2}\\ \sqrt{100+16}\\ \sqrt{116}$

Now our exact answer may be √116, however using the product rule of radicals we can further simplify the radical as such:

√116 = √4 x √29 = 2√29.

Exact Answer: <u>√116 or 2√29</u>
Approximate Answer: <u>10.77</u>
