Answer:

971 km/h

Step-by-step explanation:

The length of a planet's orbit around a star is approximately 16,540,000 km and it takes the planet about 710 Earth days to complete a full orbit.

Average speed is given as total distance traveled divided by time taken. That is:

S = D / t

Where t is in hours.

We have to convert 710 days to hours:

1 day = 24 hrs

710 days = 710 * 24 = 17040 hours

Therefore, the planet's speed is:

S = 16540000 / 17040 = 971 km/h (to 3 sf)

Simulate randomly planting 25 seeds using the randomly generated numbers  7 seeds for white flowers are planted.

To simulate randomly planting seeds using the given digits, we need to count the number of occurrences of digits 1, 2, 3, and 4 in the sequence. Each occurrence of digits 1 or 2 represents planting a seed for a white flower.

Let's count the occurrences:

19862: 1 white seed (digit 2)

28864: 2 white seeds (digits 2 and 4)

96403: 1 white seed (digit 3)

88695: 1 white seed (digit 4)

87816: 2 white seeds (digits 2 and 1)

Total white seeds: 1 + 2 + 1 + 1 + 2 = 7

Therefore, out of the 25 randomly planted seeds, 7 are for white flowers.

V = 2,560 m^3

Step-by-step explanation:

The formula for the volume of a pyramid is...

[tex]V=\frac{1}{3}Bh[/tex]

B is the area of the base, which in this case is a rectangle. We need to find the area of the rectangle to plug in for B.

The formula for the area of a rectangle is...

[tex]l*w[/tex]

We can plug in the numbers.

[tex]16*24[/tex]

= 384

Now that we have B, we can plug that into the volume formula along with the height.

[tex]V=\frac{1}{3}(384*20)[/tex]

[tex]V=\frac{1}{3}*7,680[/tex]

V = 2,560 m^3

Answer: [tex]176units^3[/tex]

Step-by-step explanation:

We have a composite figure. Find the volume of each figure individually and then add them.

Cube.

[tex]V=a^3\\V=(4units)^3\\V=64units^3[/tex]

Rectangular prism.

[tex]V=w*h*l\\V=(4units)(4units)(7units)\\V=112units^3[/tex]

-----------------------------------------------------

[tex]112units^3+64units^3=176units^3[/tex]

The volume of the figure is 176 cubic units.

The volume of a cube is given by;

[tex]\rm Volume \ of \ cube =a^3\\\\[/tex]

The volume of the figure above if a = 4 units and b = 7 units.

The volume of a cube is;

[tex]\rm Volume \ of \ cube =a^3\\\\ \rm Volume \ of \ cube =4^3\\\\ \rm Volume \ of \ cube =64[/tex]

The volume of a rectangular prism is;

[tex]\rm Volume \ of \ prism =Length \times width \times height \\\\Volume \ of \ prism =4\times 4\times 7\\\\Volume \ of \ prism= 112[/tex]

The volume of the figure = Volume of cube + Volume of a rectangular prism

The volume of the figure = 64 + 112

The volume of the figure = 176

Hence, the volume of the figure is 176 cubic units.

If you raise a cube root of -2 to the third power, the resulting number will have a congruent argument. We have

-2 = 2(cos 180º + i sin 180º)

Pick a number from the 4 given options, and raise it to the third power using DeMoivre's theorem. For example,

[tex]\left(\sqrt[3]{2}\left(\cos90^\circ+i\sin90^\circ\right)\right)^3=2\left(\cos(3\cdot90^\circ)+i\sin(3\cdot90^\circ)\right)=2(\cos270^\circ+i\sin270^\circ)=-2i[/tex]

so the first option is not a cube root of -2 because the argument 270º is not congruent to 180º. Similarly, the second and fourth options are also not cube roots of -2.

On the other hand,

[tex]\left(\sqrt[3]{2}(\cos60^\circ+i\sin60^\circ)\right)^3=2(\cos180^\circ+i\sin180^\circ)[/tex]

so the third option is a cube root of -2.

Your answer would be B. [tex]30[/tex]%

Step-by-step explanation:

To figure out the decrease, you would first subtract the two numbers.

[tex]1053 - 737.1 = 315.9[/tex]

Next, you would multiply the number by [tex]1053[/tex].

[tex]\frac{315.9}{1053} = .3[/tex]

Then, you would multiply that by [tex]100[/tex].

[tex].3 * 100 = 30[/tex]

The answer would be [tex]30[/tex]%.

[tex]1053 * .3 = 315.9[/tex]

[tex]1053-315.9 = 737.1[/tex]

As both of the values are equal to each other.

A square root of a number is a value that, when multiplied by itself, gives the number.

Here, given that,

6^(1/2) and √6

Now, we know that both have same value.

6^(1/2)=√6 ≈2.45

Hence, they are equal.

Answer:

Step-by-step explanation:

You read a graph from left to right, just like you would read words on a page in a book.  At the left-most "side" of this graph, we are way up at positive infinity.  As we move from left to right, the graph begins to drop in y values.  A drop in y values indicates a decreasing graph.  So it's decreasing, we have that part.  As the graph grows up into y values that increase forever, it will also grow in the x direction to negative infinity.  As the graph decreases in y values from left to right, the x values increase into positive infinity.  So your choice is the second one: The function is decreasing on the interval (-∞, ∞).

Step-by-step explanation:

Variable b is 7 more than variable c:

b = c + 7

Variable b is also 1 less than variable c:

b = c - 1

Answer:

B:

b = c + 7

b = c - 1

Step-by-step explanation:

"Variable b is 7 more than variable c" can be expressed mathematically as

b = c + 7

"Variable b is 1 less than variable c" can be expressed mathematically as

b = c - 1

So the second pair,

b = c + 7

b = c - 1

best models the relationship between b and c
