Answer:

The sum of coefficients = 9

Step-by-step explanation:

The given expression is,

3x⁴ + 5x² + x

There are three terms in the given expression. All the terms contains variable x.

<u>To find the coefficients of each terms </u>

term        coefficients

3x⁴            3

5x²            5

x               1

<u>To find the sum of coefficients </u>

sum = 3 + 5 + 1 = 9

Therefore the sum of coefficients = 9

<h2>Hello!</h2>

The answer is: 9

<h2>Why?</h2>

To find the sum of the coefficients of the polynomial we have, we need to evaluate x=1

So,

3(1)^4+5(1)^2+1=9

The sum of the coefficientes of the expression is 9

For a person who has a mass 60 kg , calculate the weight in Newton if 1 In equals 4.45 N , then what is the person's weight in p
wel

Answer:

The answer to your question is  a) 588.6 N   b) 132.3 N

Step-by-step explanation:

Data

mass = 60 kg

weight = ?

Process

1.- Write the formula of weight

     Weight = mass x gravity

gravity = 9.81 m/s²

2.- Substitution

     Weight = 60 x 9.81

3.- Result

     Weight = 588.6 kg m/s² = 588.6 N

4.- Convert Newtons to Pounds

                     1 pound -----------  4.45 N

                     x            ----------- 588.6 N

                     x = (588.6 x 1) / 4.45

                     x = 132.3 pounds

The choices are in the slope-intecept form: y = mx + b, where m is the slope and b is the y-intercept. Looking at the graph, the y-intercept is the point at which it intersects the y-axis. That would be -1. So, the answer is either  the 1st or 2nd choice. Next, we find the slope. Take 2 points that lie along the line. For example, points (1,2) and (2,5). Calculate for the slope.

m = (y2-y1)/(x2-x1)
m = (5-2)/(2-1)
m = 3

Hence, the graph is y = 3x - 1

Consider the following sets:
bagirrra123 [75]
U = {points on the coordinate plane}
A = {solutions to the equation y = 2x + 5}
B = {points on the line y = mx}

Value of the slope m so that  {2x + 5} ∩ {mx} =Ф
This means that {2x + 5} never intersects with {mx}
To that end m=2 (same slope), if so the 2 linear functions:

y = 2x+5 and y = 2x are PARALLEL
