Answer:

Domain is A

Range is D

Step-by-step explanation:

it's all x because the line will go up and down on both directions infinitely hitting every x coordinate. The range is all y because it will also extend infinitely upwards and downwards. This is not a parabola so there i no limitation

devlian [24]

Answer:

A = 3W² + W + 1/8πW²

Step-by-step explanation:

rectangular window is L x W

semicircle is 1/2 πr²

r = 1/2 W

L = 3W + 1

A = W(3W + 1) + 1/2 π(1/2W)²

A = 3W² + W + 1/8πW²

Marisol rode her bicycle each day for five days. estimate how far she biked in all. round each number to the nearest whole numbe
o-na [289]

Marisol biked a total of 71 miles. On the other hand, she biked about 10 more miles on Wednesday than on Thursday.

<h3>How to round numbers?</h3>

The general rule is to move the decimal number to its nearest tenth. For example, 5.6 should be rounded as 6 but 5.1 should be rounded as 5.

Now, let's round the distance covered by Marisol each day:

  • Monday: 12.3 = 12
  • Tuesday: 14.1 = 14
  • Wednesday: 17.7= 18
  • Thursday: 11.8 = 12
  • Friday: 15.2 = 15

<h3>What distance did Marisol covered?</h3>

To know this just add the distance every day:

  • 12 + 14 +18 + 12 + 15 = 71 miles

<h3>How much more did she bike on Wednesday than on Thursday?</h3>

Distance covered on Wednesday - distance covered on Thursday

  • 18 - 12 = 6 miles

Note: This question is incomplete; here is the missing information:

  • Monday 12.3
  • Tuesday 14.1
  • Wednesday 17.7
  • Thursday 11.8
  • Friday 15.2

  • Distance Formula: \displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point A(3, 8)

Point B(-1, 1)

<u>Step 2: Find distance </u><em><u>d</u></em>

  1. Substitute in points [Distance Formula]:                                                         \displaystyle d = \sqrt{(-1 - 3)^2 + (1 - 8)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                   \displaystyle d = \sqrt{(-4)^2 + (-7)^2}
  3. [√Radical] Evaluate exponents:                                                                       \displaystyle d = \sqrt{16 + 49}
  4. [√Radical] Add:                                                                                                 \displaystyle d = \sqrt{65}

Explain why the ential value of any function of the form f(x)=a (b^×) is equal to a
EastWind [94]
Initial value is when x=0

that is
f(0)=a(b^0) or
f(0)=a(1) or
f(0)=a

remember that x^0=1 for all values of x
