Just think about starting with one matchstick laid down and then think about how many more you'd have to add to finish the square. Since we have to add three more each time you can take 55 - 1 (this one in the first matchstick) and then divide by 3. 54/3 = 18

Equation for ( 6, 13) ( 7900, 5 )

tia_tia [17]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

$y=mx+b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

$(x_ {1}, y_ {1}) :( 6,13)\\(x_ {2}, y_ {2}): (7900,5)$

We find the slope of the line:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5-13} {7900-6} = \frac {-8} {7894} = - \frac {4} {3947}$

Thus, the equation of the line is of the form:

$y = - \frac {4} {3947} x + b$

We substitute one of the points and find b:

$13 = - \frac {4} {3947} (6) + b\\13 = - \frac {24} {3947} + b\\13+ \frac {24} {3947} = b\\b = \frac {51335} {3947}$

Finally, the equation is:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

Answer:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

If an orbiting satellite has a diameter of 60 cm, what is the total surface area of the satellite? (HINT: surface area = 4ℼr²)

grin007 [14]

Answer:

SA = 3,600π cm²

Step-by-step explanation:

You are given the formula, and the diameter. The formula uses radius, which is 1/2 of the diameter. In this case, r = 30. Plug that into the formula and simplify...

SA = 4π(30²)

SA = 4π(900)

SA = 3,600π
