Answer:
Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
Therefore, we have:
This equation has already been factored as far as possible. To find the roots m, first let 2m+3=0 and then solve for m: -3/2. Next, let 4m-3=0 and solve for m.
Step-by-step explanation:
multiply ,1 st x 2 and 2nd x 3
so,
10 X2 + 6y2 = 136
12 X2 - 6y2 = - 48
________________
22 X 2 = 8 8
X 2 = 88 / 22
X2 = 44
X= ± 2✓ 11
y 2= 96
y = ± 4✓ 6

Explanation:
We let 0.63 (63 being repeated) be
x
.
x
=
0.6363
...
Since
x
is recurring in 2 decimal places, we multiply it by 100.
100
x
=
63.6363
...
Next, we subtract them.
100
x
−
x
=
63.6363
...
−
0.6363
...
99
x
=
63
The recurring digits '63' cancel off and the result is that
99
x
is non-recurring.
Lastly, we divide both sides by 99 to get
x
as a fraction.
x
=
63
99
=

14.347 rounded to the nearest tenth would be 14.300. It would lie in the middle of 14.200 and 14.400 on a number line.
