Or, if your money is earning a 5 percent interest rate, you'll double it in 14.4 years (72 divided by 5 equals 14.4). If your money is earning a measly 1 percent interest rate, it will take you—yep, you guessed it—a whopping 72 years to double it.

Sketxh the graph of y=(x+3)^3 and state the points where the graph crosses the axes

gtnhenbr [62]

Answer: the graph crosses the x-axis at x = -3

Step-by-step explanation:

y = (x + 3)³

To find where the graph crosses the x-axis, let y = 0 and solve for x:

0 = (x + 3)³

0 = (x + 3) with a multiplicity of 3

-3 = x with a multiplicity of 3.

Since multiplicity is an ODD number, the graph CROSSES the x-axis at x = -3

Graph:

Leading coefficient is POSITIVE so right side goes to +∞
Degree of polynomial is ODD so left side goes to -∞

graph is attached

What is the completely factored form of 25x4 – 16y2?

jeyben [28]

Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)

so
25x^4=(5x^2)^2
16y^2=(4y^2)

(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
