Answer:

x= -1, x=3

Step-by-step explanation:

The “zeros” of a quadratic function are where the parabola intersects the x axis. In that graph the parabola touches x=-1 and x=-3. Therefore that is the answer.

Looks like 14.4 because you have to add them all together and divide by the total numbers

Which expression is equivalent to 4√x^10<br><br>x^2(4√x^2) <br>x^2.2 <br>x^3(4√x)

kotykmax [81]

$\sqrt[n]{a^m}=\a^\frac{m}{n}$

$\sqrt[4]{x^{10}}=x^\frac{10}{4}=x^{2\frac{2}{4}}=x^2\cdot x^\frac{2}{4}=x^2\sqrt[4]{x^2}$

$Used:\\\\a^n\cdot a^m=a^{n+m}$

Solve for the distance between (522, 1322) and (9000, -1337) to the third decimal.

SSSSS [86.1K]

A pair of coordinate always in a form (x, y)
Let (522, 1322) be (x₁, y₁) and (9000, -1337) be (x₂, y₂)

The distance between two coordinates is given by
Distance = $\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
Distance = $\sqrt{(522-9000)^2+(1322--1337)^2}$
Distance = $\sqrt{(-8478)^2+(2659)^2}$
Distance = $\sqrt{78946765}$
Distance = 8885.200 (rounded to three decimal place)
