Answer:
(-1)ⁿ(3)ⁿ/10
Step-by-step explanation:
The first term a = 0.3, the second term, ar = 0.9. The common ratio r = ar/a = 0.9/-0.3 = -3.
From the general term of a geometric series,
U = arⁿ⁻¹
= (0.3)(-3)ⁿ⁻¹
= (3/10)(-3)ⁿ⁻¹
= (-1)ⁿ⁻¹(3)(3)ⁿ⁻¹/10
= (-1)ⁿ(3)ⁿ/10
Answer:

Step-by-step explanation: yee yee
B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>
Answer:
11/21.
BG has a total of 11 points (when you include 0), and there are 21 points total. 11/21 cannot be simplified, your final answer is 11/21.
By definition, the equation of a circle, centered at point (a, b) is
Where r is the radius of the circumference, and is calculated as the distance from the center to any point belonging to the circumference.
We have the center (5, -4) and the point through which the circumference passes (-3, 2), then:
Finally, the equation of the circumference is:
