Answer:
The value of function at x = 2 is 8.
Step-by-step explanation:
Given : Function ![f(x)=2x^2+5\sqrt{x-2}](https://tex.z-dn.net/?f=f%28x%29%3D2x%5E2%2B5%5Csqrt%7Bx-2%7D)
We have to find the value of given function at x = 2 , that is f(2)
Consider the given function ![f(x)=2x^2+5\sqrt{x-2}](https://tex.z-dn.net/?f=f%28x%29%3D2x%5E2%2B5%5Csqrt%7Bx-2%7D)
To find the value f(2) put x = 2 in given function ,
We have,
![f(2)=2(2)^2+5\sqrt{2-2}](https://tex.z-dn.net/?f=f%282%29%3D2%282%29%5E2%2B5%5Csqrt%7B2-2%7D)
Simplify, we have,
![f(2)=8+5\sqrt{0}](https://tex.z-dn.net/?f=f%282%29%3D8%2B5%5Csqrt%7B0%7D)
Simplify further, we have,
![f(2)=8](https://tex.z-dn.net/?f=f%282%29%3D8)
Thus, the value of function at x = 2 is 8.

Answer:
(x+6)(x+2)
Step-by-step explanation:
x^2+8x+12= x^2+6x+2x+12
=x(x+6)+2(x+6)
=(x+6)(x+2)
Answer: $4,800
Step-by-step explanation:
(Assuming the interest is calculated monthly)
1. 6% of $40,000 = $2,400
2. $2,400 x 2 months = $4,800
3. Total value of account = $44,800; $4,800 is from interest
Answer:
B. (0, 4)
Step-by-step explanation:
so we need to find the value of m and n, and luckily we have 2 equations that'll help. (I'm going to use the substitution method for this instead of the Elimination method because I am lazy)
first we need to solve for m, but we already have an equation that tells us what m is equal to, m = n - 4.
now we just need to plug in our new m into the other equation and solve for n. (we are using m + 5n = 20 for that)
so now we get
(n - 4) + 5n = 20
so we solve for n
n + 5n = 24
6n = 24
n = 4
now that we know that n is 4, we can plug that into our m equation (m = n - 4)
m = 4 - 4
m = 0
now we have our m and n, and we can make our ordered pair.
(m, n)
(0, 4)
