Answer:
52 dollars.
Step-by-step explanation:
2 ounces = 6.50
÷2 ÷2
1 ounce = 3.25
3.25 x 16 = 52 dollars.
Answer:
(0,0)
Step-by-step explanation:
(0, 3) + 4 = (0,7)
(0, 7) - 7 = (0,0)
Answer:
4n²+2n as a factorial is given as:
![= (2n+1)!/(2n-1)!](https://tex.z-dn.net/?f=%3D%20%282n%2B1%29%21%2F%282n-1%29%21)
Step-by-step explanation:
We are given an expression which has to be converted into factorial form.
The expression is as follows:
![4n^{2} + 2n\\ = 2n(2n+1)\\ = (2n+1)2n\\](https://tex.z-dn.net/?f=4n%5E%7B2%7D%20%2B%202n%5C%5C%20%3D%202n%282n%2B1%29%5C%5C%20%3D%20%282n%2B1%292n%5C%5C)
Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.
Hence, multiplying and dividing by '(2n-1)!'; we get:
![= ((2n+1)(2n)(2n-1)!)/(2n-1)!](https://tex.z-dn.net/?f=%3D%20%28%282n%2B1%29%282n%29%282n-1%29%21%29%2F%282n-1%29%21)
we know that x(x-1)(x-2)! = x!, so:
![= (2n+1)!/(2n-1)!](https://tex.z-dn.net/?f=%3D%20%282n%2B1%29%21%2F%282n-1%29%21)
It is more effective if I explain using examples. So, for multiplication, you just have to multiply the magnitude, then add the exponents of the base 10. For example, when you multiply 5.2×10³ and 1.6×10², the solution would be:
(5.2)(1.6)(10³⁺²) = 8.32×10⁵
Now, for division, you will have to divide the magnitudes, and subtract the exponents by numerator minus denominator. The solution is as follows:
(5.2/1.6)(10³⁻²) = 3.25×10¹
Answer:
y = 2/3
Step-by-step explanation:
first, you have to get y by itself. you do that by adding 2 to both sides, making the equation
3y = 2. next, you divide both sides by 3, to finish getting y by itself, making the equation y = 2/3
