Hello from MrBillDoesMath!
Answer:
x = 0, +\-3
Discussion:
x^3 = 9x => subtract 9x from both sides
x^3 - 9x = 0 => factor x from both terms
x(x^2-9) = 0 => x = 0 or x^2 - 9 = 0
x = 0, +\-3
Thank you,
MrB
Answer:
70%
Step-by-step explanation:
Since it can't go over 100%, and our numbers are 7 and 3, they are 70% and 30%, which add up to 100%.
Answer:
Step-by-step explanation:
y=mx+c
So in this case, m is (-3/7), which is the slope.
(-3/7)(another slope)=-1
Another slope=3/7
A. The slope is -7/3
B. The slope is 3/7
C. The slope is -7/3
D. The slope is -3/7
Thus, the answer is the bottom of the left hand side, which is 3x-7y=14
Hope it helps!!! Good luck!!
Answer:
<em>The correct option is: C. 
</em>
Step-by-step explanation:
The two angles of the triangle are given as 60° and 60°
As the sum of all three angle in any triangle is always 180°, so the measure of the third angle will be: 180°-(60°+60°) = 180° - 120° = 60°
Now each angle of the triangle is 60°, it means the triangle is equilateral.
The base of the triangle is given as 12. So, the length of each side will be 12.
That means, the value of 
Now in the left right triangle.....
So, the value of 
Answer:
A=ε*l*c
A= 2- log₁₀ % T
Step-by-step explanation:
There is a linear relationship between the concentration of a sample and absorbance according to Beer-Lambert Law.
A=ε*l*c
where;
A=absorbance
ε=absorption coefficient
l=path length
c=concentration
Because % transmittance is transmittance value multiplied by 100 then, the equation that will allow us calculate absorbance from % transmittance value will be;
A= 2- log₁₀ % T where T is transmittance.
