Answer:

<u>sum</u><u> </u><u>is</u><u> </u><u>1</u><u>2</u><u>7</u><u>5</u>

Step-by-step explanation:

sum =  \frac{n}{2} [2a + (n - 1)d] \\  \\ sum =  \frac{50}{2} [(2 \times 1) + (50 - 1) \times 1] \\  \\ sum = 25(51) \\ sum = 1275

Select the correct word to describe the function. the equation y = startfraction 5 x cubed over 8 endfraction represents functio
balandron [24]

The functions and their descriptions are:

  • Polynomial: y = \frac{5x^3}{8} and y = 5x^3 + 8
  • Logarithm: y = 6 + 0.25\ln(x)
  • Exponential y = \frac{18}{1 + 6e^{-0.25x}}

<h3>How to describe the functions?</h3>

The functions are given as:

y = \frac{5x^3}{8}

y = 6 + 0.25\ln(x)

y = \frac{18}{1 + 6e^{-0.25x}}

y = 5x^3 + 8

The functions would be described based on the type of function they represent.

Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.

Multiply the polynomial 3x2+4x+4)(2x-4)​
Lorico [155]

Answer:

\large \boxed{6x^{3} - 4x^{2} - 8x -16}

Step-by-step explanation:

(3x² + 4x + 4)(2x - 4)

The easiest method is probably to use long multiplication.

3x²  + 4x   + 4

<u>2x   -  4             </u>

6x³ +  8x² +  8x

<u>       - 12x² - 16x - 16</u>

6x³ -  4x² -   8x -16

\text{The product of the polynomials is $\large \boxed{\mathbf{6x^{3} - 4x^{2} - 8x -16}}$}
