enario. Which statement is true about an accurate graph of this data?
The data is discrete, so the points are connected with a line.
The data is discrete, so the graph is a series of unconnected points.
The data is continuous, so the graph is a series of unconnected points.
The data is continuous, so it does not matter whether or not the points are in a line.

What would be the volume of (a) air (b) plastic in a ball with 25cm diameter made from plastic 2mm thick?
morpeh [17]

Answer:

Part a) The volume of the air is V=7,794.78\ cm^{3}

Part b) The volume of the plastic is V=386.45\ cm^{3}

Step-by-step explanation:

we know that

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

step 1

Find the volume of the complete ball (air +plastic)

we have

r=25/2=12.5\ cm ------> the radius is half the diameter

substitute

V=\frac{4}{3}\pi (12.5)^{3}

V=8,181.23\ cm^{3}

step 2

Find the volume of the air

we have that

The plastic is 2 mm thick

Convert to cm

2 mm=2/10=0.2 cm

so

The radius of the interior of the ball is

r=12.5-0.2=12.3\ cm

substitute

V=\frac{4}{3}\pi (12.3)^{3}

V=7,794.78\ cm^{3} -----> this is the volume of the air (interior of the ball)

step 3

Find the volume of the plastic

we know that

The volume of the plastic is equal to the volume of the complete ball minus the volume of the air

so

8,181.23\ cm^{3}-7,794.78\ cm^{3}=386.45\ cm^{3}

Identify a1 r and n for the sum of the geometric sequence. 1/2 + 3/8 + 9/32 + 27/128 + 81/512
Bess [88]

Answer:

a1=1/2


r=3/4


n=5

Step-by-step explanation:

a1 is the first term in the geometric series


a1=1/2  


r is the common ratio of the first and second term


r=(3/8)/(1/2)


r=3/4



where n is the no of the term in the geometric series

In algebra, the polynomial remainder theorem or little Bézout's theorem is an application of Euclidean division of polynomials. It expresses that the rest of the division of a polynomial by a direct polynomial is equivalent to. Specifically, is a divisor of if and just if a property known as the factor hypothesis.

The number multiplied at each stage of a geometric sequence is called its common ratio.

The sum of the measures
marin [14]

Answer:

x = 44°

Step-by-step explanation:

The sum of the three angles is 180°.

So, x + x + 5 + 2x -1 = 180

4x + 4 = 180

4x = 176

x = 44°
