Answer 1

Answer:

1.  144  2. 16 3. 1   4. 3x-6  

Step-by-step explanation:

So think of this as a function in a function.  So you work from the inside to the outside.  So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).  

Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]

so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)

So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144

Elaina charged $83 on her credit card to buy groceries. If the
balance is now $294, what was the balance before she bought
groceries?

Answers

Answer:

211?

Step-by-step explanation:

I'm not sure if this is correct, but:

294-83=211.

Hope this helps! :)

The balance before she bought the groceries was $277.

What are mathematical operations?In mathematics, an operation is a function which takes zero or more input values (also called "operands" or "arguments") to a well-defined output value.There are five fundamental operations in mathematics: addition, subtraction, multiplication, division, and modular forms

Given is that Elaina charged $83 on her credit card to buy groceries. The balance is now $294.

The balance before she bought the groceries is -

294 + 83

277

Therefore, the balance before she bought the groceries was $277.

Write the equation of a parabola in factored form if the x-intercepts are (3,0) and (-5,0) with a maximum point at ( -1,8)

Answers

Answer:

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)

Step-by-step explanation:

Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are

(x - 3) and (x + 5)

The equation is the the product of the factors, that is

y = a(x - 3)(x + 5)  ← a is a multiplier

To find a substitute (- 1, 8) into the equation

8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )

- [tex]\frac{1}{2}[/tex] = a

Then

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form
