Answer:

  • figure the areas of the rectangle and semicircle
  • add them together

Step-by-step explanation:

The area of the rectangle is given by ...

  A = LW

  A = (20 m)(14 m) = 280 m²

__

The area of the semicircle is ...

  A = (1/2)πr²

  A = (1/2)π(7 m)² = 24.5π m² ≈ 77 m²

__

Then the total area is ...

  280 m² +77 m² = 357 m²

_____

The width of the rectangle is the diameter of the circle, which is twice its radius. The area of a semicircle is 1/2 the area of a circle.

a) We kindly invite to check the image attached below to see a detailed graph of the <em>piecewise</em> function.

b) The <em>piecewise</em> function is continuous.

<h3>How to understand a piecewise function</h3>

A <em>piecewise</em> function is a <em>conditional</em> combination of two or more functions, whose expression depends on which value of the domain is the function evaluated at.

a) The <em>piecewise</em> function described in the question is plotted on a graphing tool (i.e. <em>Desmos</em>), whose result is presented in the image attached below.

b) A function is <em>continuous</em> if and only if there is one value from range for every value of domain. The <em>piecewise</em> function is continuous as <em>linear</em> functions are continuous and the two functions of the <em>conditional</em> combination have the same value for x = 30.

AVprozaik [17]

Answer:

(41/12)g+-23/12

Step-by-step explanation:

3(5g−1) /4 - (2g+7)/6

(15g-3)/4 - (2g+7)/6---> distributive property

3(15g-3)/12 - 2(2g+7)/12--->make the denominators same

(45g-9)/12 - (4g+14)/12---distributive property

AlexFokin [52]

Answer:

A is the correct answer.

By definition, a function is a relation where each input has exactly one output. In letter A, the inputs 0, 1, 2, and 3 all have exactly one output.

In B, the input 1 has two outputs.

In C, the input 2 has two outputs.

In D, the input 2 also has two outputs.

Please said thanks

Jenny recorded the number of basketball shots she made for each game. The histogram below shows her data. How many times did Jen
Harrizon [31]

Answer:

Answer choice a is correct, the answer would be 4.

Step-by-step explanation:

The histogram shows that the bin from 1-3 has a height of 4 shots, and all of the bins to the right include values of ≥4.

The question asks for the number of games that had less than 4 shots, which means that and number of shots greater than or equal to 4 would not be counted. Thus, only the first bin is included in the answer.
