<h2><u>
Answer:</u></h2>
The area of the poster would be <u>20ft².</u>
<h2><u>
Step-by-step explanation:</u></h2>
- First, double both the length and the width.
LENGTH : 2 x 2 = 4
WIDTH : 2.5 x 2 = 5
- Use these new dimensions to work out the area
4 x 5 = <u>20ft²</u>
Answer:
105
Step-by-step explanation:
Assuming A^2 + B^2 = C^2:
C^2 = 4 + 3 = 7
So,
C^2 * 15 = 49(15) = 105
Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.
32x^3+4x^2+41x-35

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.
