Answer:

21.068 rounded to the nearest 10th is 21.1

Step-by-step explanation:

To round a number to the nearest tenth , look at the next place value to the right . If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.

If f(x) = 3x - 1 and g(x) = x + 2, find (f+g)(x).

kirill115 [55]

Answer:

$\boxed {\boxed {\sf A. \ 4x+1}}$

Step-by-step explanation:

We are asked to find (f+g)(x). The question is essentially asking us to find the sum of f(x) and g(x).

$(f+g)(x)=f(x)+g(x)$

We know that f(x) equals 3x-1 and g(x) equals x+2. Substitute the values of the functions in.

$(f+g)(x)=(3x-1)+(x+2)$

Combine the like terms.

3x and x are like terms (both have the variable "x"
-1 and 2 are like terms (both without variables, also known as constants)

$(f+g)(x)=(3x+x)+(-1+2)$

$(f+g)(x)=(4x)+(1)=4x+1$

(f+g)(x) is equal to <u>4x+1</u> and the correct answer is A.

The first step is to find the area of the figure amd then multiply it by the weight of per metre...

<h3>Step 1</h3>

Area of figure⤵️

$\sf \: area = length \times width$

Length = 60 cm = 0.6 metre
Width = 200 cm = 2 metre

$\bf \: area = 0.6 \times 2$

$\bf \: area = 1.2 \: {m}^{2}$

<h3>Now,</h3>

Weight of 1 metre² = 0.9 kg

<h3>So, The weight of 1.2 m² is; </h3>

$\tt \: 1.2 \:{m}^{2} = 1.2 \: kg$

The framework is made up of 5 rods, So the weight will be

1.2 × 5 = 6kg
