Answer:

93.3 miles

Step-by-step explanation:

Since there are 60 minutes in an hour and 20/60 = 1/3, you can divide 280 by 3 to get the amount of miles travelled in 20 minutes.

Find the composite function (please help)
anastassius [24]

Answer:

(f o h)(x) = -10x + 32

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Composite Functions

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x³ + 8

h(x) = ∛(12 - 5x)

(f o h)(x) is f(h(x))

<u>Step 2: Find Composite Function</u>

  1. Substitute:                         (f o h)(x) = 2(∛(12 - 5x))³ + 8
  2. Evaluate:                            (f o h)(x) = 2(12 - 5x) + 8
  3. Distribute 2:                       (f o h)(x) = 24 - 10x + 8
  4. Combine like terms:         (f o h)(x) = -10x + 32

And we have our final answer!

Uche is a cartographer. He picks a scale to fit a map of India onto a page of an atlas. The page is 121212 by 121212 inches, wit
julsineya [31]

The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is: 10.5k= 3214

The page dimension is:

Length = 12

Width = 12

The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square

The margin of 0.75 on either sided means the usable dimension is:

Length = 12 - 2 * 0.75 =10.5

The dimension of India is:

Length = 3214

Width =2933

The longest side in India's dimension is:

Longest = 3214

From Uche's book, the longest dimension is:

Longest = 10.5

So, the scale equation is:

k * longest length of Uche's book = longest side of India

This gives:

k * 10.5 =3214

10.5k =3214
