GrogVix [38]1 year ago
8 0

Explanation

Step 1:

Given data

\theta\text{ = 45}

Step 2:

Write the equations relating polar to rectangular coordinates are

\theta\text{= arc}\tan (\frac{y}{x})\text{ or }\tan (\theta)\text{ = }\frac{y}{x}\text{ and r = }\sqrt[]{x^2+y^2}

Since your polar equation has no "r" we will not need the last equation.

Step 3:

\text{Substitute the value of }\theta\text{ = 45}

Therefore

\begin{gathered} \tan 45\text{ = }\frac{y}{x} \\ \tan \text{ 45 = 1} \\ 1\text{ = }\frac{y}{x} \\ \text{Cross multiply} \\ y\text{ = x} \end{gathered}

Final answer

y = x

How to solve for -3x squared + 2y squared + 5xy - 2y + 5x squared - 3y squared when x = 0.5 and y = -1/10??
Pani-rosa [81]

Answer:

0.44

Step-by-step explanation:

-3x^2 + 2y^2 + 5xy - 2y +5x^2 - 3y^2

Combine like terms

-3x^2 + 5x^2 = 2x^2 2y^2 - 3y^2 = -1y^2

2x^2 - 1y^2 + 5xy - 2y

Now plug in the solutions Note: it is easier if you have all decimals or all fractions (-1/10=-.1

2(0.5)^2 - 1(-0.1)^2 + 5(0.5)(-0.1) - 2(-0.1)

Simplify:

0.5 - 0.01 - 0.25 + 0.2

0.5 + 0.2 - 0.01 - 0.25

0.7 - 0.26

0.44

I need some help with this, I am supposed to solve for x
liq [111]

They are the same measurements, because:

from 10x + 5, first do vertical angle.

then, alternate interior angle,

then vertical angle again,

and another alternate interior angle.

For each vertical and alternate interior angles, the measurements stay the same.


Set them equal to each other, isolate and solve for x.

10x + 5 = 11x - 1

First, isolate the x. Subtract 10x from both sides, and add 1 to both sides

10x (-10x) + 5 (+1) = 11x (-10x) -1 (+1)

Simplify

5 + 1 = 11x - 10x

6 = x

x = 6

6 is your answer for x.

hope this helps
