Let h(x) = (g o f)(x) = sqrt{x+3}

Debora [2.8K]4 years ago

I am assuming you meant to write the following options

A. f(x)=x+3; g(x)=√x
B. f(x)=x; g(x)=x+3
C. f(x)=√x; g(x)=x+3
D. f(x)=3x; g(x)=√x

You need to find a fucntion f(x) that once evaluated in g(x) gives us as a result h(x)

h(x) =  g(f(x))

Looking at the options, the answer is A.

g(f(x)) = sqrt(f(x)) = sqrt (x + 3) = h(x)

Pita has 12 coins in her bag.
Allushta [10]

Answer:27/220

Step-by-step explanation:

She must have 2 �1 coins and 1 50p coin.

She can choose the 2 �1 coins 3C2 = 3 ways.

For each of those 3 ways she can choose the

50p coin 9C1 or 9 ways.

That's 3�9=27 ways to get �2.50.

She can choose any 3 coins in 12C3 = 220 ways.

The desired probability is 27 ways out of

220 ways,or 27/220, or 13.5% of the time.

Jack is investing $3,000 into an account
marin [14]

Answer:

Step-by-step explanation:

I think this is the equation for annual compunt interest

FV = PV(1 + int)^time        PV is present value    FV is the future value

PV + Interest  =  FV

FV - PV = Interest

                           FV                   -      PV

Interest  = [3000(1 + 0.03)^30]   -   3000

              =    3000(1.03)^30    -   3000

              =    3000(2.4272)   -   3000

              =    7281.79   -   3000

              =    $4282     to the nearest dollar    <------------    Fianl Answer

When Julio cracked open his piggy bank, he
jok3333 [9.3K]

Answer:

52 quarters, 42 dimes

Step-by-step explanation:

Let's call the number of quarters q, and the number of dimes d.

q+d=94

0.25q+0.1d=17.20

Subtract q from both sides of the first equation to isolate d:

d=94-q

0.25q+0.1(94-q)=17.20

0.25q+9.4-0.1q=17.20

0.15q=7.8

q=52

d=94-q=42

Hope this helps!
