The only difference between the two following expressions is
their exponent though it’s equal. If you would analyze carefully, the two
expressions are equal since 2/4 is just equal to ½. The two expressions are
equal in value so the presentation of the exponent is their only difference.
Answer:
2-7i is the correct option.
Step-by-step explanation:
We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:
2+7i
And the conjugate means in the complex number is opposite sign of imaginary part that is in general:
a+ib will have conjugate a-ib
So, the conjugate of 2+7i is 2-7i
Hence, Option d is correct.
The number of bottles in the full box by solving the equation is 12.
<h3>How to form an equation?</h3>
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of bottles in the full box = x
Initial bottles = 9
Bottles in 3 full box = 3x
Bottles in 2 box in which number of bottles is x - 1 = 2(x-1)
Now,
Total bottles in refrigerator is 67
So,
9 + 3x + 2(x - 1) = 67
9 + 3x + 2x - 2 = 67
5x = 60
x = 12
Hence "The number of bottles in the full box by solving the equation is 12".

Answer:
Step-by-step explanation:
Write a proportion comparing the Oliva Oil to Vinegar = Oliva Oil to Vinegar.
3/4 ? = 2(1/2)
3/4? = 1
? = 1 ÷ 3/4
? = 1 × 4/3
? = 4/3
For a cylinder we want the area of the base times the height for a volume.
That's a radius of 5.
A = 6 ( π 5² ) = 150π mm³
