Help with this one because I do not know how to do perpendicular plz put explanation with steps worth 50!

Answer:

Therefore, equation of the line that passes through (16,-7) and is perpendicular to the line $2x-3y=12$ is $3x+2y=34$

Step-by-step explanation:

Given:

$2x-3y=12$

To Find:

Equation of line passing through ( 16, -7) and is perpendicular to the line

$2x-3y=12$

Solution:

$2x-3y=12$ ...........Given

$\therefore y=\dfrac{2}{3}\times x-4$

Comparing with,

$y=mx+c$

Where m =slope

We get

$Slope = m1 = \dfrac{2}{3}$

We know that for Perpendicular lines have product slopes = -1.

$m1\times m2=-1$

Substituting m1 we get m2 as

$\dfrac{2}{3}\times m2=-1\\\\m2=-\dfrac{3}{2}$

Therefore the slope of the required line passing through (16 , -7) will have the slope,

$m2=-\dfrac{3}{2}$

Now the equation of line in slope point form given by

$(y-y_{1})=m(x-x_{1})$

Substituting the point (16 , -7) and slope m2 we will get the required equation of the line,

$(y-(-7))=-\dfrac{3}{2}\times (x-16)\\\\2y+14=-3x+48\\3x+2y=34......Equation\ of\ line$

Therefore, equation of the line that passes through (16,-7) and is perpendicular to the line $2x-3y=12$ is

$3x+2y=34$

The first term of a geometric sequence is 6 and the common ratio is -4 find the 6th term

mart [117]

R = - 4
t1 = 6

tn = a1*r^(n - 1)
t6 = 6 * (-4)^(6 - 1)
t6 = 6 * (-4)^5
t6 = 6 * (-1024)
t6 = -6144

Logarithms are studied for which of the following reasons? A. To help in solving exponential equations when relating the bases

skad [1K]

Answer:

To help in solving exponential equations when relating the bases cannot be used

Step-by-step explanation:

Recall an equation of the form

$a^{x}=b\\$ from the expression $a^{x}\\$ , $a\\$ is the base and the power is ${x}\\$ .

$a\neq b\\$ it is impossible to carryout the operation since the bases are not equal.

This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below

$loga^{x}=logb\\x=\frac{logb}{loga} \\$ .

Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.
