<u>Answer (1):</u>

Coefficient of any term  means the number multiplied in that term including sign.

ab^2 is same as 1ab^2.

Hence required coefficient is 1.



<u>Answer (2):</u>

4(3-7)^2+102


=4(-4)^2+102


=4(16)+102


=64+102


=166


Hence final answer is 166


<u>Answer (3):</u>

\sqrt{\frac{49}{25}}


=\frac{\sqrt{49}}{\sqrt{25}}


=\frac{7}{5}


Hence final answer is \frac{7}{5}

<u>Answer:</u>

1. Coefficient is 1

2. 166

3. \frac{7}{5} or 1\frac{2}{5}

<u>Step-by-step explanation:</u>

1. Since there is no number mentioned before the term ab^2 therefore its coefficient is 1. (1ab^2)


2. 4(3 – 7)^2 + 102

Using the order of operations, we will start by solving in the brackets first to get:

4(-4)^2+102

4(16)+102

64+102

166


3. \sqrt{\frac{45}{25}  }

SInce both the numerator and the denominator are under the square root so we can write them as:

\frac{\sqrt{49}} \sqrt{25}

\frac{7}{5}

\frac{7}{5} is an improper fraction so we can write it in mixed form as 1\frac{2}{5}

Answer:

\huge\boxed{\sf V = 56.5 \ in.^3}

Step-by-step explanation:

Radius = r = 3 in.

Height = h = 2 in.

<u>Volume:</u>

\sf Volume \ of \ the \ cylinder = \pi r^2 h\\\\V = (3.14)(3)^2(2)\\\\V =(3.14)(9)(2)\\\\V = (3.14)(18)\\\\V = 56.5 \ in.^3\\\\\rule[225]{225}{2}
