Remember to round your number
THE ANSWER IS 8.10
Answer:
117.2
Step-by-step explanation:
Rounding a number to the nearest tenth:
A number rounded to the nearest tenth will have one decimal place.
To do this, we look at the second decimal digit.
If it is less than 5, the first decimal digit is kept.
Otherwise, one is added to the first decimal digit.
In this question:
117.22666
The second decimal digit is 2, which means that we keep the first decimal digit which is also 2.
So, the number rounded to the nearest tenth is 117.2.
Answer:
1. x=3 x=1
2. x=0
Step-by-step explanation:
We want f(x) to equal g(x)
f(x)=g(x)
1/(x-2) = (x-2)
Using cross products
1 = (x-2) * (x-2)
1 = x^2 -2x-2x+4
Subtract 1 from each side
1-1 = ^2 -2x-2x+4-1
0 = x^2 -4x+3
Factoring
What number multiplies to 3 and adds to -4
-3*-1 = 3
-3+-1 = -4
0= (x-3) (x-1)
Using the zero product property
x-3 =0 x-1=0
x=3 x=1
2. f(x)=x^2+4x+2
g(x)=(1/2)^ x+1
From the graph,we can see they intersect at x=0
First we divide 102 by 12.75 to get the hours which is 8 hours. So it would take 8 hours
The addition of the function is:
(f+g)(x)= f(x)+g(x)
So, (f+g)(5)= f(5)+g(5)
To find f(5) and g(5), plug in 5 for x in both the functions.
So, f(5)= 8(5)-13 = 40-13 = 27
g(5)= 5-9= -4
Now we can add f(5) and g(5) to get the answer.
So, (f+g)(5)= 27 +(-4) = 27-4= 23
Hence, (f+g)(5)= 23
