We know that
the equation of the line in point-slope------------> <span> (y – y1) = m(x – x1)
</span>the equation of the line in slope intercept forms. -----> y =mx+b
find the slope m
point <span>(8,-2) & (7,-4).
m=(y2-y1)/(x2-x1)---------> </span>(-4+2)/(7-8)=-2/-1----------> m=2
Part A)
find the equation of the line in point-slope using <span>(8,-2)
</span>(y – y1) = m(x – x1)---------> (y-(-2)) = 2*(x – 8)-------> y+2=2x-16
<span>y=2x-16-2--------> y=2x-18
</span>Part B)
find the equation of the line in point-slope using (7,-4)
(y – y1) = m(x – x1)---------> (y-(-4)) = 2*(x – 7)-------> y+4=2x-14
y=2x-14-4--------> y=2x-18<span>
</span>Part C)
find the equation of the line in slope intercept forms
using (7,-4)
y=mx+b--------> -4=2*7+b----------> -4=14+b-----------> b=-18
then
y=2x-18
Part D)
find the equation of the line in slope intercept forms
using (8,-2)
y=mx+b--------> -2=2*8+b----------> -2=16+b-----------> b=-18
then
y=2x-18
0.03 compare to 0.003
While comparing decimals we write the decimals one below the other according to the place value of each digits in place value chart
ones -- point -- Tenths -- Hundredths -- Thousandths
0 . 0 3
0 . 0 0 3
Now we compare each digit left to right. We have 3 in hundredths and 0 in hundredths place. 3 is greater
So 0.03 is greater than 0.003
0.03 > 0.003
4^0=1
1-1=0
10*0=0
since when something is brought to the power of 0, it equals 1. Then when put into the equation the brackets = 0 therefore the whole equation equals 0
Notice, the third decimal place is 9 in 3.469644...
and after the 469 there's a 6, that means we can round that 469 to a 470
3.470.
Hello!
To solve this exercise, we must use the formula below:
Knowing these values, let's replace them in the formula to obtain r:
So, the radius of this circle is 10cm.
Hope this helps!
