Expand. Your answer should be a polynomial in standard form. (3c + 2)(c^2-6c-4)

evablogger [386]

Answer:

After expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

Step-by-step explanation:

We need to expand the polynomial $(3c + 2)(c^2-6c-4)$

Multiply the terms:

$(3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8$

So, after expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331.

deff fn [24]

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

$\text{ log } y = 3.331$

We need to find the value of 'y' when x = 4

$log_{10}y = 3.331$

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

$10^{log_{10}y} = 10^{3.331}\\\\\text{10 power log base 10 cancels, we get }\\\\y = 10^{3.331}\\\\y = 2142.89$

On rounding to nearest whole number, we get 2143

Thus Option D is correct
