Can someone pls explain this?

ryzh [129]

Answer:

A piecewise function.

Step-by-step explanation:

The problem you showed is a piecewise function.

In this problem, you have to plug in 3 for the value x.

However, if you take a look at the conditions that value x has, it never says that x can equal 3. Thus, this function cannot be true.

Way to check this input is undefined:

Plug in 3 for the variable x. On the first function, your output will be 4. On the second function, your output will be 8.

According to the definition of a function, a function can have many inputs but only one output. In this case, this function has one input, that is 3, but produces two outputs.

A group of students is given a 10 by 10 grid to cut into individual unit squares. The challenge is to create two squares using a

givi [52]

Answer:

8 is the side length of the greater square. 100=x^2+(x-2)^2

Step-by-step explanation:

64+36=100

8 squared plus 6 squared equals 10 squared

8 is 2 more than 6

100=x^2 +y^2

x-y=2

100=x^2+(x-2)^2

$-7a-10=20-3a$

Combine like terms:
$-4a -10 = 20$
$-4a = 30$

Solve for a:
$a = -\frac{30}{4} = -7.5$

Your answer: a = -7.5

Felicia places a rectangular rug that measures 10 feet by 11 feet in a triangular room with a base of 30 feet and height of 22 f

arsen [322]

Answer:

1. Area of rectangular rug is $110 ft^{2}$

2. Area of triangular room is $330ft^{2}$

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, rectangle and triangle.

step one

let us start by solving for the area of the rectangular rug

given data

Area A = ?

Length l = 11 ft

Width w= 10 ft

we know that the area of a rectangle is expressed as

$Area=Length * Width$

substituting our given data we have

$Area= 11*10\\Area= 110 ft^{2}$

step two

let us solve for the area of the triangular room

given data

Area A = ?

base b = 30 ft

height h= 22 ft

we know that the area of a triangle is expressed as

$Area= \frac{1}{2} *base* height\\$

substituting our given data we have

$Area= \frac{1}{2} * 30* 22\\Area=\frac{660}{2} \\Area= 330 ft^{2}$
