Answer:

=> Apply law of cosine

$c^2=a^2+b^2-2abcos\left(C\right)$

=> input value

$z^2=6.5^2 + 9.4^2-\left(6.5\right)\left(9.4\right)\left(cos\left(131\right)\right)$

=> simplify

$z=\sqrt{\left(6.5^2+\:9.4^2\right)-\left(6.5\right)\left(9.4\right)\left(-0.65605902899\right)}$

=> calulcation

$z=\sqrt{-61.1\cos \left(131^{\circ \:}\right)+130.61},\:z=-\sqrt{-61.1\cos \left(131^{\circ \:}\right)+130.61}$

=> apply rule: Distance must be greater than 0

which is about 14.51828

4p+6-3 combine like terms?

amm1812

Answer:

4p+3

Step-by-step explanation:

Because 4 has the variable p next to it, 4 can not be the same as 6 or 3 because they are whole numbers. So the only thing you can do here is 6-3, which is 3.

Serjik [45]

Answer:

m=2-2

m=0

Step-by-step explanation:

U need to do substitution

So u carry both 2 from that side to cross the equal to sign. One becomes positive because it is carrying a negative sign at the other side

Slope of -5 2). (3,9)

podryga [215]

Answer:

The slope of the given two points is $m=\frac{7}{8}$

Step-by-step explanation:

Given two points are (-5,2) and (3,9)

To find the slope with these two points

Let $(x_{1},y_{1})$ and $(x_{2},y_{2})$ be the given points

By using Slope Formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{9-2}{3-(-5)}$

$m=\frac{9-2}{3+5}$ ( subtracting and adding the corresponding terms)

$m=\frac{7}{8}$

Therefore slope is $m=\frac{7}{8}$

The slope of the given two points is $m=\frac{7}{8}$
