15=1/2+3/2x+10

enot [183]

Answer:

x = 1/3

Step-by-step explanation:

15 = 1/2 + 3/2x + 10

15 - 1/2 -10 = 3/2x

9/2 = 3/2x

9 x 2x = 3 x 2

18x = 6

x = 6/18

x = 1/3

Given the function f(x) = 4x - 2, explain and show how to find the average rate of change between x = 2 and x = 4.

zalisa [80]

Answer:

The average rate of change between x = 2 and x = 4 is of 4.

Step-by-step explanation:

Average rate of change:

The average rate of change of a function f(x) in an interval [a,b] is given by:

$A = \frac{f(b)-f(a)}{b-a}$

In this question:

$f(x) = 4x - 2, b = 4, a = 2$

Thus:

$f(b) = f(4) = 4(4) - 2 = 16 - 2 = 14$

$f(a) = f(2) = 4(2) - 2 = 8 - 2 = 6$

Average rate of change:

$A = \frac{f(b)-f(a)}{b-a}$

$A = \frac{14-6}{4-2}$

$A = \frac{8}{2}$

$A = 4$

The average rate of change between x = 2 and x = 4 is of 4.

What is the future value of 300000 with an interest rate of 17% per annum for 30 days?

Anvisha [2.4K]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$300000\\
r=rate\to 17\%\to \frac{17}{100}\to &0.17\\
t=years\to \frac{30}{365}\to &\frac{6}{73}
\end{cases}
\\\\\\
A=300000\left(1+0.17\cdot \frac{6}{73}\right)$
