Answer:

The value of f(g(3) =  1,008

Step-by-step explanation:

<u>Step:-1</u>

Given f(x) =3 x ^ 2 + 2 x

and g(x) = 3x+9

      h(x) = 12+x

Given g(x) = 3x+9

  put x =3

      g(3) = 3(3)+9

      <u>  g(3) = 18</u>

<u>Step :-(2)</u>

f(g(3)) = f(18)

f(g(3) = 3(18)^2 +2(18) (since f(x) =3 x ^ 2 + 2 x)

        = 1,008

<u>Final answer</u>:-

The value of f(g(3) =  1,008

laiz [17]

9514 1404 393

Answer:

  78.71 mph

Step-by-step explanation:

You're looking for the solution to ...

  d = 88

  0.0015r^2 +r = 88

  0.0015r^2 +r -88 = 0

Using the quadratic formula*, we find ...

  r = (-1 +√(1² -4(0.0015)(-88)))/(2×0.0015)

  r = (-1 +√1.528)/0.003 = 0.236123/0.003 = 78.7077

The speed of the car was about 78.71 mph.

_____

* The quadratic formula will also give a negative answer of about -745 mph, which is not relevant to the situation.

Gannon has deposited $742 in a savings account that earns interest at a rate of 3.4% compounded monthly. What will the account b
marta [7]
Firstly, solve the effective annual interest (ieff) with the equation,
 
                          ieff = (1 + i/m)^m -1

where i is the interest rate and m is the number of times the interest is compounded in a year. In this problem, m is 12

Substituting the values, 
                            ieff = (1 + 0.034/12)^12 - 1 =0.03453

To solve for the future (F) amount of the present investment (P), 
                                       
                                        F = P x (1 + ieff)^n

where n is number of years.
 
                                        F = ($742) x (1 + 0.03453)^15

Thus, the answer is $1234.76.
