General Formulas and Concepts:

<u>Algebra I</u>

  • Functions
  • Function Notation
  • Expand by FOIL

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = x²

k(x) = 2x + 1

(k × f)(x) = k(x)f(x)

<u>Step 2: Find</u>

  1. Substitute in functions:                                                                                     (k × f)(x) = x²(2x + 1)
  2. Expand [FOIL]:                                                                                                  (k × f)(x) = 2x³ + x²

Aliun [14]

Answer:

The perimeter of the p triangle = 38.4 cm

Step-by-step explanation:

Given

The perimeter of a triangle z be = 48 cm

The triangle is dilated by a scale factor of 0.8

To determine

What is the perimeter of the triangle after it is dilated by a scale factor of 0.8?

  • As the scale factor < 1, it means the new perimeter will be reduced.

The new perimeter of the triangle p can be calculated by multiplying the perimeter of the original triangle z by 0.8

i.e.

Perimeter of triangle p = 48 × 0.8 = 38.4 cm

Therefore, the perimeter of the triangle p is = 38.4 cm

yKpoI14uk [10]

Answer:

Result = 0.0045

Step-by-step explanation:

Given

0.09 * 0.05

Required

Determine the result

Following Charlie's steps:

0.09 is a 2 decimal placed digit

and

0.05 is a 2 decimal placed digit

So, the product is as follows:

9 --------- 2 decimal place

5 --------- 2 decimal place

------------------------------------------

45 --------- 4 decimal place

Shifting the decimals in 45 to 4 decimal places will give us: 0.0045

<em>Hence, the final answer is 0.0045</em>
