Answer:

$\sf{\cos(30) = \frac{7 \sqrt{3} }{w} } \\ \sf{ \frac{ \sqrt{3} }{2} = \frac{7 \sqrt{3} }{w} } \\ \sf{w = \frac{7 \sqrt{3} \times 2 }{ \sqrt{3} } = 14}$

How do I solve this problem

densk [106]

You would put 6 in for k and 2 in for c, making it "5*6-20+8", which equals 18. Hope this helps! :)

Write a quadratic equation with roots of 3/4 and -4

Vaselesa [24]

A quadratic equation given roots is solved by using the relation

${x}^{2} - (sum \: of \: roots)x + product \: of \: roots$

from the question,

sum of the root will be

$\frac{3}{4} + ( - 4) = \frac{3}{4} - 4$

$= \frac{3 - 16}{4}$

$= \frac{ - 13}{4}$

and also, product of the roots will

$\frac{3}{4} \times ( - 4) = - 3$

now substituting the sum of roots and product of roots into the equation

${x}^{2} - ( - \frac{13}{4} )x - 3$

$= {x}^{2} + \frac{13}{4} x - 3$

as the quadratic equation for the root 3/4 and -4
