Answer:
39
Step-by-step explanation:
This weird notation just means we are going to put one equation inside the other, and then solve.
Makes more sense when you write it like this:
g ( f ( x ) )
To solve, we are going to take the 3, plug it into the f ( x )
g ( f ( 3 ) )
^ This makes it a lot easier to understand what we have to do.
----------------------------------------------------------------------------------------------------------
Ok, so now we evaluate f ( x ) at 3.
4 ( 3 ) - 2
f( x ) = 10
Then we plug it into g ( x )
4 ( 10 ) - 1
= 39
Here's how it looks in total:
4 ( 4 ( 3 ) - 2 ) - 1 = 39
Slightly more complicated, but that's why i broke it down step by step.
Answer:
7/12 feet
Step-by-step explanation:
5/6 - 1/4
LCD is 12... 10/12 - 3/12 = 7/12
You want to calculate the interest on $2000 at5.8% interest per month after six years?
Here is your formula: I =p*r*t
P is the principal amount which is $2000
R is the rate of interest which is 5.8% per month
T is the time involved whihc is six years
You’re interest is 8352.00
The equation of parabola becomes y = -2/25(x-3)^2 + 4.
According to the statement
we have given a graph and from this graph we have to find the equation of parabola in the general form.
So,
we know that the equation of parabola in general form is
y = a(x-h)^2 +k - (1)
From the graph we have:
a point on the graph is (x,y) = (-2,2)
the vertex of the graph is (h,k) = (3,4)
Now, substitute these values in the equation number (1)
Then
y = a(x-h)^2 +k
2 = a(-2-3)^2 +4
2 = a(-5)^2 +4
2 = a(25) +4
25a = -2
a = -2/25.
Now put a = -2/25 and (h,k) = (3,4) in the equation(1).
Then
the equation of parabola becomes y = -2/25(x-3)^2 + 4
So, The equation of parabola becomes y = -2/25(x-3)^2 + 4.
