n = 5.33→
Step-by-step explanation:
Answer:
Step-by-step explanation:
formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x2 = 2
x1 = - 7
y2 = -6
y1 = - 6
Solution
d = sqrt( (2 - - 7)^2 + (-6 - - 6)^2 )
d = sqrt( 9^2 + (-6 + 6)^2 )
d = sqrt(9)^2
d = 9
Use Y=-2/3x + b
and then plug in (-7,-4)
-7 is x, so plug that in for x
Y=-2/3(-7) + b
and plug in y, -4
-4=-2/3(-7) +b
plug into calculator and then solve algebraically!
b doesn’t mean anything, it’s just what i used for the y axis, really you could use any letter
Since the roots are 2,3i, and -3i, you can write it as
(x-2)(x-3i)(x+3i)=(x-2)(x^2+9)=x^3-2x^2+9x-18.
Part A:
The circumference of the circle is 197.92.
Explanation:
The formula for circumference of a circle is C=2 πr. If you insert the numbers, it would be C=2 x 3.14 x 31.5. Hence, the answer is 197.92.
Part B:
The area is 3117.25 square cm.
Explanation:
The formula for area of a circle is A= πr ². Inserting the numbers, it is A=3.14 x 31.5 ². Therefore the answer is 3117.25 cm ².
