HELP ASAP

Damm [24]

Answer:

He can make it with Max's audio goods

44.575 miles < 45 miles

Step-by-step explanation:

The angle of the truck driver = 180 - (60 + 69) = 51°

By using sin Rule:

40/sin51 = Max's auto goods/sin60 = Jimmy's car supply/sin69

∴ Max's auto goods = 40(sin60)/sin51 = 44.575 miles

∴ Jimmy's car supply = 40sin(69)/sin51 = 48.052 miles

∵ The truck driver can travel another 45 miles

∴ He can make it with Max's audio goods because 44.575 < 45

Write the equation of the line perpendicular to 2x+3y=9 that passes through (-2,5). Write your answer in slope-intercept form. S

Harman [31]

ANSWER

$y = \frac{3}{2} x + 8$

EXPLANATION

The line given to us has equation,

$2x + 3y = 9$

We need to write this equation in the slope intercept form to obtain,

$3y = - 2x + 9$

$\Rightarrow \: y = - \frac{2}{3}x + 3$

The slope of this line is

$m_1 = - \frac{2}{3}$
Let the slope of the perpendicular line be

$m_2$

Then
$m_1 \times m_2 = - 1$

$- \frac{2}{3} m_2= - 1$

This implies that,

$m_2 = - 1 \times - \frac{3}{2}$

$m_2 = \frac{3}{2}$

Let the equation of the perpendicular line be,

$y = mx + b$

We substitute the slope to get,

$y = \frac{3}{2} x + b$

Since this line passes through
$(-2,5)$
it must satisfy its equation.

This means that,

$5= \frac{3}{2} ( - 2)+ b$

$5 = - 3 + b$

$5 + 3 = b$

$b = 8$

Wherefore the slope-intercept form is

$y = \frac{3}{2} x + 8$
