Hello!

Input, is another name for the domain of a function, or an x-value. Since we are given the equation, y = 7x² + 3, we can substitute the x-value of 4, into the equation, and solve for the output, the range, or a y-value of a function.

y = 7(4)² + 3 (simplify the exponent)

y = 7(16) + 3 (use the distributive property)

y = 112 + 3 (simplify)

y = 115

Therefore, you are correct! The answer is 115. :)

Answer:

$6.03

Step-by-step explanation:

Let's begin by listing out the given variables:

height (h) = 12 cm, diameter (d) = 8 cm, r = d ÷ 2  ⇒ r = 4 cm, cost of coconut oil (c) = $0.01 /cm³

The formula of cylinder is given by:

V = πr²h = π * 4² * 12 = <u>603.1858 cm³</u>

cost of filling the tin can with coconut oil = cost of coconut oil * Volume of cylinder

Cost = c * V = 0.01 * 603.1858

Cost = $<u>6.03</u>
