Answers

The number 143 is a composite number due to having more than two factors.

The factors of the number 143 are 1, 11 and 13.

What is the difference between a prime number and a composite number?

Prime number has only two factors i.e. 1 and the number itself while composite numbers can have more than two factors.

143 = 1*11*13

Since the number 143 has 3 factors i.e. 1, 11, and 13.

So, The number 143 is a composite number.

Therefore, The number 143 is a composite number due to having more than two factors.

2^x+5 = 3^1-x use logarithms to solve the exponential equation. round answer to 3 decimal places.

Answers

2^(x+5)=3^(1-x)\ \ \ \ \ /log_2()\n\nlog_22^(x+5)=log_23^(1-x)\n\nx+5=(1-x)log_23\n\nx+5=log_23-xlog_23\n\nx+xlog_23=log_23-5\n\nx(1+log_23)=log_23-5\ \ \ \ /:(1+log_23)

x=(log_23-5)/(1+log_23)\n-------------\nlog_23\approx1.5849625\n----------------\nx\approx(1.5849625-5)/(1+1.5849625)\approx-1.321
2^x+5 = 3^1-x
take log on both sides
(x+5)log2=(1-x)log3
0.3010(x+5) = (1-x)0.4771
0.3010x + 1.5050 = 0.4771 - 0.4771x
0.7781x= -1.0279
x=-1.320

Write the equation of the line that contains the given point and has the given slope. (–1, 4), slope is –3

Answers

\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{4})~\hspace{10em}slope = m\implies -3\n\n\n \begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\n\cline{1-1}\ny-y_1=m(x-x_1)\n\n\cline{1-1}\end{array}\implies y-4=-3[x-(-1)]\n\n\ny-4=-3(x+1)\implies y-4=-3x-3\implies y=-3x+1
Y = -3x + 4. This is because the y value is -4 so that would be the y intercept and -3 is the slope as said in the question

Roger has a nail that is 12 centimeters long. He measures and records the length of the nail as 15 centimeters. What is the percent error in Roger's measurement? 15% 17% 20% 25%

Answers

First, calculate the difference between 15 and 12. The operation, subtraction, will give us the answer of 3. Then, divide the calculated value by 12 since this it the theoretical length of the nail. Multiply the quotient by 100% to arrive to the final answer. That is (3/12)(100%). The final answer to this item is 25% which is the last choice.

The percent error in Roger's measurement is :25%.

Percent of error

Using this formula

Percent of error=Length-Centimeters long/Centimeters long×100

Let plug in the formula

Percent  error=15-12/12

Percent error=3/12×100

Percent error=25%

The percent error in Roger's measurement is :25%.
