Write an equation in the form y = mx + b for the line which contains the points (8, 25) and (1, 4).

1 answer:

8 0

$\frac{25-4}{8-1}= \frac{21}{7} =3$ . So the slope is 3 which you can plug in one of the points and get the final equation which is : $y=3x+1$

Three odd-shaped blocks of chocolate have the following masses and center-of-mass coordinates: (1) 0.310kg , ( 0.200 m, 0.320m )

Katarina [22]

Answer:

The x coordinate is 0.047m while y coordinate is 0.081 m

Step-by-step explanation:

The coordinates of the center of the mass of the system are given as follows

$x_c=\dfrac{\sum_{i=1}x_im_i}{\sum_{i=1}m_i}\\y_c=\dfrac{\sum_{i=1}y_im_i}{\sum_{i=1}m_i}$

So from the data

m1=0.310, x1=0.20,y1=0.320

m2=0.410,x2=0.110,y2=-0.380

m3=0.210,x3=-0.300,y3=0.630

Now by substitution of the values in the above equation

$x_c=\dfrac{\sum_{i=1}x_im_i}{\sum_{i=1}m_i}\\x_c=\dfrac{x_1m_1+x_2m_2+x_3m_3}{m_1+m_2+m_3}\\x_c=\dfrac{0.310*0.2+0.410*.110+0.210*-0.3}{0.310+0.410+0.210}\\x_c=0.047m\\\\\\y_c=\dfrac{\sum_{i=1}y_im_i}{\sum_{i=1}m_i}\\y_c=\dfrac{y_1m_1+y_2m_2+y_3m_3}{m_1+m_2+m_3}\\y_c=\dfrac{0.310*0.320+0.410*-0.380+0.210*.630}{0.310+0.410+0.210}\\y_c=0.081m$

So the x coordinate is 0.047m while y coordinate is 0.081 m

A statement we accept without proof is called:

Snowcat [4.5K]

The correct answer is C. A statement we accept without proof is called a postulate. It is also known as an axiom. These are rules which are accepted to be true without any evidence that will prove these. For instance, the postulates in the kinetic molecular theory.

Can someone help out?

Crank

Answer:

b ≥ 5,000.

Step-by-step explanation:

1. Use the information given in the problem to write the inequality... such as box tops & the amount of 5,000 box tops.

2. b represents the number of box tops for the fundraiser. Therefore, based on the information provided, the value of b must be greater than or equal to 5,000 box tops. So, you get the inequality is:

b ≥ 5,000

3. Then you graph it, you must use a closed circle for ≥.

~~(the graph is different, but you should be able to understand it.)

hopefully my answer helps! ♡
