Answer:
Rational
Step-by-step explanation:
If you can write it as a fraction (=ratio), it is rational.
-6/10 = -0.6
Answer:
8x-5y=-20
Step-by-step explanation:
First you have to collect it like terms (5y-8x=20
Then reorder the terms (-8x+5y=20)
Next is to change the signs (8x-5y=-20)
Then you have your answer
The values are vx =
, vw =
and m∠x = 45°, for the given right angle diagram.
Step-by-step explanation:
The given is,
Right angled triangle XVW,
XW = 14
m∠V = 90°
m∠W = 45°
Step:1
Given diagram is right angle triangle,
Trigonometric ratios for right angle is,
∅
............................(1)
∅
.........................(2)
∅
..........................(3)
Step:2
For the value of VX,
∅ 
From given,
∅ = 45°
XW = 14
Above equation becomes,
45 
Where, Sin 45 =
,

Step:3
For the value of VW,
∅ 
From given,
∅ = 45°
XW = 14
Above equation becomes,
45 
Where, cos 45 =
,

Step:4
For the value m∠x = a,
a 
From given,
VX = 
VW = 
Above equation becomes,
a 
a = 1
a =
(1)
a = 45°
m∠x = a = 45°
Step:5
Check for solution,
m∠v = m∠w + m∠x
= 45° + 45°
90° = 90°
Result:
The values are vx =
, vw =
and m∠x = 45°, for the given right angle diagram.
Answer:
√2 x √2 = 2
Step-by-step explanation:
Square roots that aren't perfect squares are irrational.
For Ex: √2 is irrational.
But √2 x √2 = √4 = 2. 2 is rational
Ex. 2 : √8 x √2 = √16 = 4. 4 is rational
Answer: <em>is it 4, maybe?</em>
