The difference of the square of a number and 5 is equal to 4 times that number. Find the negative solution.

Alexeev081 [22]

Answer:

$x=-1 or x=5$

Step-by-step explanation:

let the number be 'x'.

According to the statement given above:

$x^2-5=4x$

or

$x^2-4x-5=0$

Factorizing the quadratic equation for 'x'

$x^2+x-5x-5=0$

Taking common from the equation:

$x(x+1)-5(x+1)=0\\(x+1)(x-5)=0\\(x+1)=0, (x-5)=0\\x=-1,x=5$

The solution of the equation is $x=-1 or x=5$

Find the common ratio, r, in the following geometric sequence. 27, 9, 3, 1,…

Shtirlitz [24]

To find the common ratio
divide by the previous numb/number beside it:
$\frac{9}{27}=\frac{1}{3},\:\quad \frac{3}{9}=\frac{1}{3},\:\quad \frac{1}{3}=\frac{1}{3}$

so $r=\frac{1}{3}$

Suppose f(π/3) = 3 and f '(π/3) = −7,

insens350 [35]

Et's give this a go:h(x) = cos(x) / f(x)
derivative (recall the quotient rule)h'(x) = [ f(x) * (-sin(x)) - cos(x)*f'(x) ] / [ f(x) ]^2
simplifyh'(x) = [ -sin(x)*f(x) - cox(x)*f '(x) ] / [ f(x) ]^2h'(π/3) = [ -sin(π/3)*f(π/3) - cox(π/3)*f '(π/3) ] / [ f(π/3) ]^2h'(π/3) = −(3–√/2)∗(3)−(1/2)∗(−7)/(3)2
h'(π/3) = (−33–√/2+7/2)/9

And you can further simplify if you want, I'll stop there.
