Answer:
12+2√6+2√10
Step-by-step explanation:
(√2+√3)² + (√5+√2)²=2+3+2√6+5+2+2√10=12+2√6+2√10
We are given the functions:
f(x) = 4 x – 5 --->
1
g(x) = 3 x + 7 --->
2
To find for the value of f(x) + g(x), all we have to do is
to add equations 1 and 2:
f(x) + g(x) = 4 x – 5 + 3 x + 7
f(x) + g(x) = 7 x + 2 = y
In this case, for any real number value assign to x, we get
a real number value of y. This is because the function is linear.
Therefore the domain of the function is all real numbers.
So for this you will be using an exponential equation, which is
with a=initial value, b=growth/decay, y = total balance, and x = # of years
In this case, a = 500, and since with this problem the initial value is growing, you will add 100% to 6% to get 106%, or 1.06. The equation will be formed as such: ![y=500(1.06)^x](https://tex.z-dn.net/?f=%20y%3D500%281.06%29%5Ex%20)
With this problem, just plug in 15 into x and solve for y: ![y=500(1.06)^{15}\\ y=1198.28](https://tex.z-dn.net/?f=%20y%3D500%281.06%29%5E%7B15%7D%5C%5C%20y%3D1198.28%20)
In short, after 15 years Tom will have $1198.28 in his account.
Answer:
9800000
Step-by-step explanation:
X*94 +688*6 = 267*100
94x+4128=26700
94X=22572 /94
X=240.128
