to find X you need to add up the other two angles inside the triangle which are 36 and 63, that equals 99 and then subtract that number from 180, which equals 81.

To find Z you will follow the 180 rule and subtract 180 from what you got for X(81), this will equal 99

To find Y you will add what you got for Z(99) plus 13 and then subtract that number from 180, which will give you 68

So X=81, Y=99, and Y=68

Which is the slope of the line that passes through the points (3,5) and (8,7)?

Hatshy [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

$m=\boxed{\frac{2}{5}}$

»»————-　★　————-««

Here’s why:

The formula for the slope of two given lines given is 'rise over run'.

⸻⸻⸻⸻

$\boxed{\text{Slope Formula:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\\rightarrow (x_1,y_1),(x_2,x_1) - \text{Two Points Given}$

⸻⸻⸻⸻

We are given the points (3,5) and (8,7).

⸻⸻⸻⸻

$\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{7-5}{8-3}\\\\\rightarrow \boxed{m=\frac{2}{5}}$

⸻⸻⸻⸻

Find a third-degree polynomial function with real coefficients and with zeros at -4 and -3 5i

Charra [1.4K]

If -3+5i is a solution, then by the conjugate root theorem, -3-5i is also a solution. We find the polynomial by multiplying together the factors. If x = -4, then x + 4 is the factor. If x = -3+5i, then (x-(-3+5i)) is a factor, and so is (x-(-3-5i)). Simplifying those down gives us as the first factor as (x+3-5i) and the second as (x+3+5i). We can FOIL those 2 together to get their product, and then FOIL in x+4. FOILing the 2 complex factors together gives us $x^2+3x+15ix+3x+9+15i-15ix-15i-25i^2$ . If we combine like terms and cross out things that cancel it's much easier than what it looks like there! It simplifies down to $x^2+6x-25i^2$ . Since i^2 = -1, it simplifies further to $x^2+6x-25(-1)$ and finally, to $x^2+6x+25$ . Now we will FOIL in x+4. $(x^2+6x+25)(x+4)=x^3+6x^2+25x+4x^2+24x+100$ . Our final simplified third degree polynomial is $x^3+10x^2+49x+100$
