Answer:
First one is uh a basement lol
Second one is a doorbell?
Step-by-step explanation:
The common ratio of the given terms in the geometric sequence is that number which is the answer derived from dividing the second term by the first term and the third term by the second term. In this item, the value of r (common ratio) is as calculated below.
In this item, we should be mindful that i = sqrt (-1). The ratio is,
r = (√-1)(√-1)/(√-1) = -1 (√-1)/-1 = √-1
For the next three terms,
n₄ = (-1)(√-1) = -i
n₅ = (-i)(√-1)) = 1
n₆ = (1)(√-1) = i
Thus, the next three terms are -1, 1, and i, respectively.
Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
Here is my answer. I hope this is helpful.
<u>Given:</u>
A larger circle consisting of two circles with radii of 4 cm and 8 cm each.
<u>To find:</u>
The area of the shaded region.
<u>Solution:</u>
The centers of the circles with radii 4 cm and 8 cm lie on the same line as the center of the larger circle.
So the diameter of the outer circle cm.
If the diameter is 24 cm, the radius is cm.
The area of the shaded region is obtained by subtracting the areas of the two inner circles from the outer circle.
The area of a circle
The area of the circle with radius 12 cm square cm.
The area of the circle with radius 8 cm square cm.
The area of the circle with radius 4 cm square cm.
The area of the shaded region square cm.
Rounding this off to the nearest tenth, we get the area of the shaded region as 201 square cm.
