Answer:

-3\frac{9}{10} ft

Step-by-step explanation:

Given that the change is -13/10 in 10 seconds

Here, you can write this statement as;

10s = -13/10

30s=?----------------perform cross-multiplication

(-13/10 * 30 ) /10

=\frac{-13}{10} *\frac{30}{10} =\frac{-39}{10} \\\\\\=-3\frac{9}{10}

5(2x – 3) = 5 Part A: How many solutions does this equation have? (4 points) Part B: What are the solutions to this equation? Sh
Maru [420]

ANSWER

a) One Solution

b) the solution is x=2

EXPLANATION

The given equation is:

5(2x - 3) = 5

We expand to get;

10x - 15 = 5

Group similar terms;

10x = 15 + 5

This implies that,

10x = 20

Divide both sides by 10 to obtain,

x = 2

Use set-builder notation to describe the following sets: (a) {1,2,3,4,5,6,7} (b) {1, 10, 100, 1000, 10000} (c) {1,1/2, 1/3, 1/4,
Alja [10]

Answer:

A) The set builder notation is: {n | n∈Z, 1≤n≤7}.

B) The set builder notation is: \{10^x | x=0,1,2,3,4\}

C) The set builder notation is: \{\frac{1}{n} | n\in z\}

D) The set builder notation can be: \{x\ \in R | x=x^3\ and\ x\neq 1\}

Step-by-step explanation:

Consider the provided information,

We need to use set-builder notation to describe the following sets.

(a) {1,2,3,4,5,6,7}

Here, the number are integer starting from 1 to 7.

Thus, the set builder notation is: {n | n∈Z, 1≤n≤7}.

(b) {1, 10, 100, 1000, 10000}

The above set can be written as:

\{1, 10, 100, 1000, 10000\}=\{10^0, 10^1, 10^2, 10^3, 10^4\}

Thus, the set builder notation is: \{10^x | x=0,1,2,3,4\}

(c) {1, 1/2, 1/3, 1/4, 1/5, ...}

Here the numerator is 1 for each term but denominator is natural number.

Thus, the set builder notation is: \{\frac{1}{n} | n\in z\}

(d) {0}

The set builder notation can be: \{x\ \in R | x=x^3\ and\ x\neq 1\}
