Answer:

<h3>On a coordinate plane, a cube root function goes through (negative 8, negative 2), has an inflection point at (0, 0), and goes thorugh (8, 2).</h3>

Step-by-step explanation:

f(x)=\sqrt[3]{x}\\\\f(-8)=\sqrt[3]{-8}=-2\to(-8,\ -2)\\\\f(0)=\sqrt[3]{0}=0\to(0,\ 0)\\\\f(8)=\sqrt[3]{8}=2\to(8,\ 2)\\\\\\\sqrt[3]{a}=b\iff b^3=a\\\\\text{Therefore:}\\\\\sqrt[3]{-8}=-2\ \text{because}\ (-2)^3=-8\\\sqrt[3]0=0\ \text{because}\ 0^3=0\\\sqrt[3]{8}=2\ \text{because}\ 2^3=8

What is the volume ,In cubic units ,of Anna’s figure ?
attashe74 [19]

The first column has 10 cubes.

The question states that the other two columns each have 4 fewer cubes than the first column.

10 - 4 = 6

This means that each of the other 2 columns have 6 cubes each.

Column 1: 10 Cubic units

Column 2: 6 Cubic units

Column 3: 6 Cubic units

10 + 6 + 6 = 22

Anna’s Figure has 22 Cubic Units

I need help answering this question 5/13t=-9
Lera25 [3.4K]
You divide by 5/13. Remember when dividing fractions you multiply by the reciprocal. 5/13 cancels on the left side, leaving t.

So here you have -9/(5/13), but we can put -9 as -9/1, then instead of dividing by 5/13, multiply by 13/5: 117/5. This evens out, when divided, to t=23.4

Factorise the polynomial x^3 - 5x^2 +2x +8, (x-4) is a factor.<br><br> Pllsss i need help ASAP! T^T
vfiekz [6]

Answer:

  x^3 - 5x^2 + 2x + 8

= (x^3 - 4x^2) - (x^2 - 4x) - (2x - 8)

= x^2(x - 4) - x(x - 4) - 2(x - 4)

= (x^2 - x - 2)(x - 4)

= [x(x - 2) + (x - 2)](x - 4)

= (x - 2)(x + 1)(x - 4)

Hope this helps!

:)
