Answer:
the value in the present of a sum of money, in contrast to some future value it will have when it has been invested at compound interest.
Step-by-step explanation:
Diameter of the larger gear х см
1/4х = 16 - 2.5
1/4x = 13.5
x = 13.5 * 4
x = 54 cm - diameter of the larger gear /
Hello!
To solve this equation, we need to isolate the variable on one side of the equation to see what it equals.
As you can see, 2.7 is added. To get it onto the other side and cancel it from the one side, you will subtract it from both sides as shown below. Note that because of the commutative property, we can switch the places of 2.7 and x.
x+2.7-2.7=17-2.7 (Note that 2.7=2.7 is 0 in this equation.
x=14.3
Our solution is x=14.3
I hope this helped you learn how to solve equations a bit better!

Step-by-step explanation:
<u>Roots of a polynomial</u>
If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula

Where a is an arbitrary constant.
We know three of the roots of the degree-5 polynomial are:

We can complete the two remaining roots by knowing the complex roots in a polynomial with real coefficients, always come paired with their conjugates. This means that the fourth and fifth roots are:

Let's build up the polynomial, assuming a=1:

Since:


Operating the last two factors:

Operating, we have the required polynomial:
