Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

Diameter ( d ) = 15 in
Pi ( π ) = 3.14

$\underline{ \underline{ \text{To \: find}}} :$

Circumference ( C )

$\underline{ \underline{ \text{Solution}} }:$

$\boxed{ \sf{Circumference \: of \: a \: circle ( C ) = \pi \: d}}$

⇢ $\sf{3.14 \times 15}$

⇢ $\sf{47.1 \: in.}$

$\red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{47.1 \: in.}}}}}}}$

Answer:

See Below

Step-by-step explanation:

I'm not going to do the homework for you, but I will complete three of the problems to help you understand the process.

We are converting between different units of measurement.

Here are the conversions to know:

12 inches = 1 foot

3 feet = 1 yard

1760 yard = 1 mile

5280 feet = 1 mile

We need to convert 7 feet into inches.

7 feet * 12 inches per foot = 84 inches

Now we know:

84 inches = 7 feet

What's the difference is between 84 inches, and 18 inches?

84 inches - 18 inches = 66 inches

We need 66 more inches to get a length of 7 feet.

We need to convert 2 miles into yards.

2 miles * 1760 yards per mile = 3520 yards.

Now we know:

3520 yards = 2 miles

What's the difference between 3520 yards and 2000 yards?

3520 yards - 2000 yards = 1520 yards

We need 1520 more yards to make 2 miles

We need to convert 108 inches into feet.

108 inches / 12 inches per foot = 9 feet

Since there is no remainder,

9 feet = 108 inches.

Hopefully you can see what is going on here and do the rest yourself.

Answer: 116.12

Explanation:

13 x 7 = 91

13 - 5 = 8

8 / 2 = 4

3.14(4)^2 = 50.24

50.24 / 2 = 25.12

91 + 25.12 = 116.12

I hope this helped!

$\large\underline{\rm Solution }:-$

Given function to us is ,

$\implies f(x) = 3x^3 - 5x + 1$

The domain of the expression will be all real numbers except where the given expression is not defined . Therefore , the domain is ,

$\underline\text{ In Interval Notation :- }$

$\implies \boxed{ Domain : ( -\infty , +\infty ) }$

$\underline\text{ In Set Builder Notation :- }$

$\implies \boxed{ Domain : \{ x | x \in \mathbb{R} \}}$

Answer:

substitution is distributive for letters

ie) when we work out for 2x + 5 and 3x -4

we can set = to each other distribute to find x then plug in.

plug in means substitute.

Step-by-step explanation:

transitive is distributive for values for same coefficients in problem solving like Pythagoras a + b = c. but that is not equation checking unless equation replaces it. Answer is substitution for distributive letters.
