Your mother has a new cell phone. It comes with 18 applications already installed. She uses only "2" /"3" of those applications.
ANEK [815]

So, out of 18, she only uses 2/3, so it will be 18*2/3, plus the additional 12 she downloaded.

You were given the polynomial f(x)=3x^3+13x^2+19x+k and you know that f(-2)=0find k
eduard

Answer:

k = 10

Explanation:

The initial polynomial is:

f(x)=3x^3+13x^2+19x+k

If f(-2) = 0, then when we replace x by -2, the result will be 0. It means that we can write the following equation:

\begin{gathered} f(-2)=3(-2)^3+13(-2)^2+19(-2)+k=0 \\ 3(-2)^3+13(-2)^2+19(-2)+k=0 \end{gathered}

Therefore, we can solve for k as follows:

\begin{gathered} 3(-8)+13(4)+19(-2)+k=0 \\ -24+52-38+k=0 \\ -10+k=0 \\ -10+k+10=0+10 \\ k=10 \end{gathered}

So, the value of k is 10

a right rectangular prism has a length of 2 1/2 feet and width of 3 feet and a height of 1 and 1/2 feet. Unit cubes with side le
anygoal [31]
The volume of the right rectangular prism is the product of all its dimensions, length, width and height. Since all these dimensions are given, therefore, we can directly calculate the volume of the right rectangular prism by substitution to the formula.

V = L*W*H
V = (2.5 ft)(3 ft)(1.5 ft)
<em>V = 3.375 ft³ or 3 and 3/8 ft³</em>
