if we change 2½ years to an improper fraction, that'd be 5/2 years.

$\bf ~~~~~~ \textit{Simple Interest Earned Amount}\\\\A=P(1+rt)\qquad \begin{cases}A=\textit{accumulated amount}\\P=\textit{original amount deposited}\to& \$850\\r=rate\to 2\%\to \frac{2}{100}\to &0.02\\t=years\to &\frac{5}{2}\end{cases}\\\\\\A=850\left( 1+0.02\cdot \cfrac{5}{2} \right)\implies A=850(1.05)\implies A=892.5$

Find each function value. f(9) if f(x)=5x-16

andriy [413]

If f(x) = 5x - 16, then value of f(9) is 29

Solution:

Given function is f(x) = 5x - 16

We are asked to find the value of f(9)

To find the value of f(9), we have to substitute x = 9 in given function and solve the function

Therefore, substitute x = 9

f(x) = 5x - 16

f(9) = 5(9) - 16

Multiply 5 with 9 which gives 45

f(9) = 45 - 16

Subtract 16 from 45

f(9) = 29

Thus value of f(9) is 29

The area of a rectangle is given by 3x^3+14x^2-23x+6

dmitriy555 [2]

The length of the rectangle is defined by $(x-1)\cdot \left(x-\frac{1}{3} \right)$ .

Geometrically speaking, the rectangle area is equal to the product of its base and its length. According to the statement the area is represented by a third order polynomial and width by a first order polynomial and, thus, length must be a second order polynomial.

By factor the polynomial we get the following roots:

$A = 3\cdot x^{3}+14\cdot x^{2}-23\cdot x + 6$
