Determine whether the infinite geometric series converges or diverges. If it converges, find the sum, and if it diverges then explain why.
48 + 36 + 27 + 81/4 + ...
Geometric series means
|r|<1Lets spot out common ratio
36/48=3/427/36=3/4Its less than 1
Hence series converges
Sum:-
a/1-r48/(1-3/4)48/1/4192Answer:
Series converges
Sum = 192
Step-by-step explanation:
General form of geometric series: [tex]a_n=ar^{n-1}[/tex]
where:
a is the initial termr is the common ratioGiven series: 48, 36, 27, 81/4, ...
[tex]\implies a = 48[/tex]
[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{36}{48}=\dfrac34[/tex]
Geometric series converges when |r| < 1
Geometric series diverges when |r| ≥ 1
[tex]\textsf{As }r=\dfrac34\ \implies|\dfrac34| < 1\:\implies\:\textsf{series converges}[/tex]
Sum of an infinite geometric series:
[tex]S_\infty=\dfrac{a}{1-r}\quad\textsf{for}\:|r| < 1[/tex]
Substituting values of a and r:
[tex]\implies S_\infty=\dfrac{48}{1-\frac34}=192[/tex]

What is special about the triangle that forms the yield sign ?
Answer:
Step-by-step explanation:
Just as the “stop sign” uses its 8 sides to communicate about “sharing the stop in all directions”, the yield sign’s 3 sides communicate as well. That triangle communicates that things’ll get tighter and tighter for you, as you move up. It’s sort of implicit - your space is going away. You need to stop and yield to others whose space hasn’t gone away.

a sphere has a volume of 2304pi mm^. find the diameter of the sphere
Answer:
My answer is The diameter is 24
please please help me
Answer:
A. 36
Step-by-step explanation:
Right triangle angles in degrees always add up to 180° degrees. In addition, it must have a right angle (hence the name right triangle), which is 90 degrees.
Given the angle in degrees is 54, we can add 90 and 54 and subtract it from 180 to find the missing angle.
[tex]54+90=144[/tex]
Now, subtract from 180.
[tex]180-144=36[/tex]
Therefore, the degrees of the missing angle is 36.

Answer:
The answer is D
Step-by-step explanation:
I just did this
The figure which has rotational symmetry is figure A.
What is rotational symmetry?It is the property of a shape that it looks same after some rotation by a partial turn.
How to identify shape?In the figure given first shape has equal length of sides at each direction which means that if we rotates this figure then we will get same looking figure.
In the second figure when we rotates the figure vertically the it will look like a tower.
When we rotates the third figure they also look different.
In the graph figure are shown after some rotation.
Hence among all the figures given first figure has rotational symmetry.

Answer:
36 in²
Step-by-step explanation:
Area of the figure
Area (small rectangle) left + Area (big rectangle) right3 x (6 - 4) + 5 x 63 x 2 + 306 + 3036 in²Answer:
The answer is 36 ft²
Step-by-step explanation:
Let us divide this whole figure into 2 rectangle, a big and a small.
Rectangle 1: (Small)
Length (l) = 2 ftBreadth (b) = 3 ft(Area 1) = l × b
A = 2 × 3 = 6 square ft
Rectangle 2: (Big)
Length (l) = 6 ftBreadth (b) = 5 ft(Area 2) = l × b
A = 6 × 5 = 30 square ft
Now,
Total Area of figure = Area of Rectangle 1 + Area of Rectangle 2.
Total Area = 6 + 30 = 36 square ft.
Thus, The area of the figure is 36 ft².
2. Which ordered pair is a solution of the equation y =

a. (0,-7)
b. (-1,-7)
c. (1, -7)
d. (2,26)
Answer:
c. (1, -7).
Step-by-step explanation:
Substitute the given values to see which set fits:
y = -11x + 4
Try (0, -7):
-11(0) + 4 = 4 . Not this one as we are looking for the result -7.
Try (-1, -7):
-11(-1) + 4 = 11+4 = 15. Not this one as we are looking for the result -7.
Try (1, -7):
-11(1) + 4 = -11+4 = -7. This is correct.

Circle A and B
Assume the following parameters:
The center of circle A is (2,3) with a radius of 2The center of circle B is (3,2) with a radius of 3To start with;
The circle A must be reflected across the line y = x with the following transformation rule:
(x,y) -> (y,x)
So, we have:
(2,3) -> (3,2)
Next, the radius of A must be dilated by 3/2 as follows:
New Radius = 3/2 * 2 = 3
After the transformations, we have the following parameters:

To figure out how many __ hours were spent on the bus.Let's set up an equation,
-we'll assume that 'x' are the unknown hours spent on the bus.
The unknown hours spent on the bus plus the hours spent both on walking/and the train will equal a total of 39 hours.
So,
14 + x = 39

x = 25, the hours Jerry spent riding on the bus is 25 hours.
Answer:
25 hours
Step-by-step explanation:

Which inequality would result in the shaded solution on the unit circle to the right?
Explanation:
Cosine is positive in quadrants I and IV, but quadrant IV isn't shaded in so we can rule out choice A.
Sine is positive in quadrants I and II. So far it looks like choice B could work. In fact, it's the answer because sin(pi/6) = 1/2 and sin(5pi/6) = 1/2. So if 0 ≤ sin(x) < 1/2, then we'd shade the region between theta = 0 and theta = pi/6; as well as the region from theta = 5pi/6 to theta = pi.
Choice C is ruled out because tangent is positive in quadrants I and III, but quadrant III isn't shaded.
Choice D is ruled out for similar reasoning as choice A. Recall that [tex]\sec(x) = \frac{1}{\cos(x)}[/tex]
Answer:
0 ≤ sin x < 1/2.
Step-by-step explanation:
sin π6 = 1/2
sin 5π/6 = 1/2
sin 0 and sin 180 = 0
The dotted line indicates that the value of the sine is less than 1/2 and the solid line indicates that value is greater or equal to zero.
So the inequality is 0 ≤ sin x < 1/2

Answer:
327.5 feet²
Step-by-step explanation:
Let's divide the figure into multiple shapes (Refer to image). To determine the area of the figure, we need to find the area of the divided shapes, then sum it up to obtain the area of the figure.
Determining the area of the triangle:
Given dimensions:
Height = 11 feetDetermining the base of the triangle:
[tex]22 + b + 5 = 7 + 8 + 17[/tex]
[tex]27 + b = 32[/tex]
[tex]b = 32 - 27[/tex]
[tex]b = 5 \ \text{ft}[/tex]
Substituting the base and the height:
[tex]\text{Area of triangle} = \frac{1}{2} \times \text{Base} \times \text{Height}[/tex]
[tex]\text{Area of triangle} = \frac{1}{2} \times 5\times11[/tex]
Simplifying the R.H.S to determine the area:
[tex]\text{Area of triangle} = 5\times5.5[/tex]
[tex]\text{Area of triangle} = 27.5 \ \text{ft}^{2}[/tex]
Determining the area of rectangle₁
Given dimensions:
Length = 17 feetBreadth = 5 feetSubstitute the length and the breadth:
[tex]\text{Area of rectangle}_{1}} = LB[/tex]
[tex]\text{Area of rectangle}_{1}} = (5)(17)[/tex]
Simplify the R.H.S to determine the area:
[tex]\text{Area of rectangle}_{1}} = 85 \ \text{feet}[/tex]
Determining the area of rectangle₂
Given dimensions:
Length = 5 + 7 feetBreadth = 8 feetSubstitute the length and the breadth:
[tex]\text{Area of rectangle}_{2} = LB[/tex]
[tex]\text{Area of rectangle}_{2} = (7 + 5)(8)[/tex]
Simplify the R.H.S to determine the area
[tex]\text{Area of rectangle}_{2} = (7 \times 8) + (5 \times 8)[/tex]
[tex]\text{Area of rectangle}_{2} = 56+ 40[/tex]
[tex]\text{Area of rectangle}_{2} = 96 \ \text{feet}^{2}[/tex]
Determining the area of rectangle₃
Given dimensions:
Length = 17 feetBreadth = 7 feetSubstitute the length and the breadth:
[tex]\text{Area of rectangle}_{2} = LB[/tex]
[tex]\text{Area of rectangle}_{2} = (17)(7)[/tex]
Simplify the R.H.S to determing the area:
[tex]\text{Area of rectangle}_{2} = 119\ \text{feet}^{2}[/tex]
Determining the area of the figure:
A (Figure) = A (Triangle) + A (Rectangle₁) + A (Rectangle₂) + A(Rectangle₃)
= 27.5 + 85 + 96 + 119
= 327.5 feet²
