Its 2.59%. i mean i figured it out and i got 2.59%
Answer:
E' (3, 1)
F' (-2, -1)
G' (-1, 4)
Step-by-step explanation:
The rule for rotating 180° is (x, y) ⇒ (-x, -y)
E is at (-3, -1). When the rule is applied, E' is at (3, 1)
F is at (2, 1). When the rule is applied, F' is at (-2, -1)
G is at (1, -4). When the rule is applied, G' is at (-1, 4)

Answer:
The width is 64.3 inches
Step-by-step explanation:
Given
--- diagonal
--- height
Required
Determine the width (w) of the TV
To do this, we make use of Pythagoras theorem which is illustrated as:
![d^2 = h^2 + w^2](https://tex.z-dn.net/?f=d%5E2%20%3D%20h%5E2%20%2B%20w%5E2)
So, we have:
![90^2 = 63^2 + w^2](https://tex.z-dn.net/?f=90%5E2%20%3D%2063%5E2%20%2B%20w%5E2)
Evaluate all squares
![8100 = 3969 + w^2](https://tex.z-dn.net/?f=8100%20%3D%203969%20%2B%20w%5E2)
Collect like terms
![w^2 = 8100 - 3969](https://tex.z-dn.net/?f=w%5E2%20%3D%208100%20-%203969)
![w^2 = 4131](https://tex.z-dn.net/?f=w%5E2%20%3D%204131)
Take positive square roots of both sides
![w = \sqrt{4131](https://tex.z-dn.net/?f=w%20%3D%20%5Csqrt%7B4131)
-- approximated
6/10 = 0.6
A decimal number that has digits that do not go on forever.
Answer:
Step-by-step explanation:
9x - 4 + 5x + 16 = 180
14x + 12 = 180
14x = 168
x = 12
