Which graph represents y = RootIndex 3 StartRoot x minus 5 EndRoot? On a coordinate plane, a cubic function has a point of inflection at x = 0 and crosses the x-axis at x = 5. On a coordinate plane, a cubic function has a point of inflection at x = negative 5 and crosses the x-axis at x = 2. On a coordinate plane, a cubic function has a point of inflection at y = negative 5 and crosses the x-axis at y = negative 5. On a coordinate plane, a cubic function has a point of inflection at x = 5 and crosses the x-axis at x = 5.

On a coordinate plane, a cubic function has a point of inflection at x = 5 and crosses the x-axis at x = 5.

Step-by-step explanation:

y = (x - 5)^⅓

Cuts the x-axis at:

0 = (x - 5)^⅓

x = 5

Cuts the y-axis at:

y = (0 - 5)^⅓

y = cuberoot(5)

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
