Using the quadratic formula to solve 5x=6x squared -3, what are the values of x?

1 answer:

7 0

Answer: 5+sqrt(97)/12, 5-sqrt(97)/12 or we write it as [5+/-sqrt(97)]/(12)

5x=6x^2-3

6x^2-5x-3=0

x=-b+/-sqrt(b^2-4ac)/2a

x=-(-5)+/-sqrt((-5^2-4(6)(-3))/2(6)

x= 5+/-sqrt(97)/12

And decimal form is;

x=1.237, -0.4041

If anyone has any questions please feel free to ask and I’ll reply ASAP. Thanks

Solve for c of the right triangle

Ede4ka [16]

In order to solve this triangle we must use cosine law:
$c^{2} = a^{2} + b^{2} - 2ab*cosC$

Now let's plug in the values we are given:
$c^{2} = 5^{2} + 8^{2} - 2(5)(8) * cos 67$
$c^{2} = 25 + 64 - 80*cos67$
$c = \sqrt{80-cos67}$

The following is the converse of a conditional statement. If it is not April 17th, then it is not Matt's birthday. What is the i

user100 [1]

The original statement would remove the two "not" values from the converse, giving "If it is April 17th, then it is Matt's birthday." Similarly, to find the inverse of the original conditional, simply flip the two statements. As such, the inverse would read "If it is Matt's birthday, then it is April 17th."
