Step-by-step explanation:
| v − 455 | < 23
Writing this without absolute values:
-23 < v − 455 < 23
Solving for v:
432 < v < 478
In interval notation: (432, 478)
This interval is within the range of blue wavelengths, so the fireworks will be blue.
Answer:
16+28÷2-6=26
10-4x2=2
Step-by-step explanation:
16+28÷2-6
=16+16-6
=32-6
=26
10-4x2
=10-8
=2
Answer:
Therefore the measure of∠ A is 60.07.
Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠ B = 90°
BC = 13 ....Side opposite to angle A
AC = 15 .... Hypotenuse
To Find:
m∠A = ?
Solution:
In Right Angle Triangle ABC ,Sine Identity,
Substituting the values we get
Therefore the measure of∠ A is 60.07
The answer to your question above, I will just illustrate it down.
<span>sqrt(3 x +7 ) = 1 - sqrt(x + 2 )
</span><span>square both sides:
3x + 7 = 1 -2sqrt(x = 2) + x + 2
Then it would become like this,
</span><span>2x + 4 = -2sqrt( x + 2 )
</span>Divide both sides by -2 to eliminate the -2 on the left side with sqrt.
Then <span>square both sides:
x^2 + 4x + 4 = x + 2
</span><span>x^2 + 3x + 2 = 0
</span><span>(x + 2) (x + 1) = 0
</span><span>x=-2, -1 there is no sqrt for-1
</span>so the answer is -2
