Given polynomial :

f(x) = 2x³–5x² + 5x

Let the number to be subtracted be n

(x is already in equation so, n is better)

since, 2x – 3 factor given

→

$f ( \frac{3}{2} ) = 0$

So,

$2x {}^{3} - 5x {}^{2} + 5 {x}^{2} - n$

$2x {}^{3} - 5x {}^{2} + 5x - n = 0 \\ \\ 2( \frac{3}{2} ) {}^{3} - 5( \frac{3}{2} ) {}^{2} + 5( \frac{3}{2} ) - n = 0 \\ \\ 2 \times \frac{27}{8} - 5 \times \frac{9}{4} + 5 \times \frac{3}{2} - n \: = 0 \\ \\ \frac{27}{4} - \frac{45}{4} + \frac{15}{2} - \frac{n}{1} = 0 \\ \\ 27 - 45 + 30 - 4n = 0 \\ \\ 12 - 4n \: = 0 \\ \\n = \frac{ - 12}{ - 4} \\ \\ n = > 3$

Considere os logaritmos log3=0,477 , log4=0,602 e / log5=0.699 logaritmos determine o valor de log5 12.

anygoal [31]

Given that :

log3=0.477 , log4=0.602 and log5=0.699

Now , as you know that

$\log\text{MN}=\log M +\log N$

We have to find the value of

$\log_{5}12$

So, $\log_{5}12$ = $\frac{\log12}{ \log5}$

= $\frac{\log 4+\log 3}{\log 5}\\$

Now Putting the values of log3, log4 and log5 in the above expression

$\log_{5}12=\frac{0.477 +0.602}{0.699}$

=1.0079/0.699

=1.5436..

=1.544 (approx)

So, the value of $\log_{5}12$ is 1.544(approx).

Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3x + 3.

alexandr1967 [171]

Parallel lines have the same slope, but different y-intercepts

The slope of both lines is -2/3

To find the equation that passes through (7, 3) we can use the point-slope formula: y - y1 = m (x - x1)

y - (3) = (-2/3) (x - (7))

y - 3 = -2/3x + 4 and 2/3

y = -2/3x + 7 and 2/3

or

y = -2/3x + 7.67
