Work out the angle of x please answer ASAP!!

geniusboy [140]

Given:

The figure of a pentagon.

To find:

The value of the x.

Solution:

We know that, the sum of all interior angles of a pentagon is 540 degrees. So,

$(5x-25)+(6x+25)+(6x-3)+(9x)+(7x+15)=540$

$(5x+6x+6x+9x+7x)+(-25+25-3+15)=540$

$33x+12=540$

Subtract both sides by 12.

$33x+12-12=540-12$

$33x=528$

Divide both sides by 33.

$x=\dfrac{528}{33}$

$x=16$

Therefore, the value of the x is 16.

Please Help Mee!!! Write equations for the lines shown.

abruzzese [7]

A. Blue: y = -3x + 8
Black: y = 3x + 2
B. You find the ordered pair (x, y) that is a solution for both functions ( find the point where the two lines cross)
C. There’s two ways you can solve algebraically (using the equations); substitution and elimination. I don’t know which you need to use to answer but feel free to use my notes on how to do substitution for help. I don’t really have any on elimination ( it’s so easy you don’t even really need notes) or I would use them to explain.

Find y'' by implicit differentiation. 3x^3 + 4y^3 = 5

We first have to find the first derivative before we can find the second. First derivative with respect to x is $9x^2+12y^2 \frac{dy}{dx}=0$ so $12y^2 \frac{dy}{dx}=-9x^2$ and $\frac{dy}{dx}=- \frac{9x^2}{12y^2}=- \frac{3x^2}{4y^2}$ . That's the first derivative. Now for the second it's probably easiest to use the quotient rule, even though it's usually long and drawn out. That looks like this: $\frac{dy}{dx}= \frac{4y^2(-6x)-[-3x^2(8y \frac{dy}{dx})] }{(4y^2)^2}$ which simplifies a bit to $\frac{dy}{dx}= \frac{-24xy^2+24x^2y( \frac{dy}{dx}) }{16y^4}$ . We will multiply both sides by that denominator to get rid of it which leaves us with $16y^4 \frac{dy}{dx}=-24xy^2+24x^2y \frac{dy}{dx}$ . Get both dy/dx terms on the same side, and then factor it out. $\frac{dy}{dx}(16y^4-24x^2y)=-24xy^2$ . Divide to isolate the dy/dx: $\frac{d^2y}{dx^2}= \frac{-24xy^2}{16y^4-24x^2y}$ . There's no simplifying you could do after that that would make any significant difference.
