Answer:
![\sqrt{2} (3\sqrt{2} +\sqrt{14})=6+2\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%20%283%5Csqrt%7B2%7D%20%2B%5Csqrt%7B14%7D%29%3D6%2B2%5Csqrt%7B7%7D)
Step-by-step explanation:
Given : ![\sqrt{2} (3\sqrt{2} +\sqrt{14})](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%20%283%5Csqrt%7B2%7D%20%2B%5Csqrt%7B14%7D%29)
Solution:
![\sqrt{2} (3\sqrt{2} +\sqrt{14})](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%20%283%5Csqrt%7B2%7D%20%2B%5Csqrt%7B14%7D%29)
![3*2+\sqrt{28})](https://tex.z-dn.net/?f=3%2A2%2B%5Csqrt%7B28%7D%29)
![6+2\sqrt{7}](https://tex.z-dn.net/?f=6%2B2%5Csqrt%7B7%7D)
Thus , ![\sqrt{2} (3\sqrt{2} +\sqrt{14})=6+2\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%20%283%5Csqrt%7B2%7D%20%2B%5Csqrt%7B14%7D%29%3D6%2B2%5Csqrt%7B7%7D)
Thus the solution is irrational since square root 7 does not have a perfect square and equal to 6+2square root of 14
Answer:100B + 50M ? 25000
Step-by-step explanation: CZ 75B has a firing pin block which makes for a longer SA trigger pull. CZ 75 has the superior trigger. Aren't the magazines different (and not interchangeable) as well? IIRC, the older 75 mags are not easy to find, and can be expensive.Apr 22, 2011
Answer:
Does not factor; domain = -∞<x<∞, range = f(x) ≤ 2.
Step-by-step explanation:
Assuming your end goal is to factor the polynomial
![y=-x^{2} +2x+1](https://tex.z-dn.net/?f=y%3D-x%5E%7B2%7D%20%2B2x%2B1)
If we use the guess and check method we can see that there is no way to factor this polynomial.
However, if you are looking for a domain and range we can graph it on a graphing calculator. Just by looking at the graph, we can see that the domain is all real numbers, or -∞<x<∞, and the range is f(x) ≤ 2.
I hope this helped!
Answer: the company should invest $12191 each week
Step-by-step explanation:
The amount that the company needs is $5,400,000
We would apply the periodic interest rate formula which is expressed as
P = a/[{(1+r)^n]-1}/{r(1+r)^n}]
Where
P represents the weekly payments.
a represents the amount that the company needs
r represents the rate.
n represents number of weekly payments. Therefore
a = 5,400000
There are 52 weeks in a year
r = 0.079/52 = 0.0015
n = 52 × 14 = 728
Therefore,
P = 5400000/[{(1+0.0015)^728]-1}/{0.0015(1+0.0015)^728}]
5400000/[{(1.0015)^728]-1}/{0.0015(1.0015)^728}]
P = 5400000/{2.98 -1}/[0.0015(2.98)]
P = 5400000/(1.98/0.00447)
P = 5400000/442.95
P = $12191
