Answer:

Distance = 21.0049 inches

Step-by-step explanation:

Given the following data;

Speed = 3.395 inches per minute.

Time = 6.187 minutes

To find the distance;

Distance = speed * time

Substituting into the equation, we have;

Distance = 3.395 * 6.187

Distance = 21.0049

Answer:

≈1130.97336 yd

Step-by-step explanation:

the formula to find the surface is A= 2 π r h + 2 π r 2

where r is the radius and h the height. you subsitute it with your value.

r = 9 yd and h = 11 yd

so, A= 2 π r h + 2 π r 2 = 2 x π x 9 x 11 + 2 x π x 9^2 ≈ 1130.97336 yd

Answer:

Please check the explanation.

Step-by-step explanation:

1) Writing the equation of the pattern

Figure 1 has 4 circles.

Figure 2 has 7 circles.

Figure 3 has 10 circles.

Thus, the sequence becomes

4, 7, 10,...

Finding the common difference between the adjacent terms

d = 7 - 4 = 3, d = 10 - 7 = 3

As the common difference is the same, so this represents the Arithmetic sequence.

so

d = 3

as

a₁ = 4

Thus, the nth term of the Arithmetic sequnce is

aₙ = a₁ + (n-1)d

aₙ = 4 + (n-1)3

aₙ = 4 + 3n - 3

aₙ = 1 + 3n

2) Determining the circles in the 23rd figure

As the nth term is given by

aₙ = 1 + 3n

putting n = 23

a₂₃ = 1 + 3(23)

a₂₃ = 1 + 69

a₂₃  = 70

3) Determining the figure having 82 circles

As the nth term is given by

aₙ = 1 + 3n

Given

aₙ = 82

To determine

n=?

Thus,

aₙ = 1 + 3n

82 = 1 + 3n

3n = 82-1

3n = 81

Dividing both sides by 3

n = 27

Therefore, 27th figure will have 82 circles.

Step-by-step explanation:

distance from the sun makes how hot or cold it is

^2 = SQUARED( to the second power)

Answer:

2. 2x times 2x equals 4x^2 since x times x equals x^2(and 2 times 2 equals 4. then positive i times negative i equals -i^2 which can transfer to be 1.

Step-by-step explanation:

2. 2x * 2x = 4x^2

   +i * -i = -i^2

   -i^2 can be transferred into positive 1.

   i is a variable. if you divide -i^2 by -i, then that equals i, which is 1.

3. The same thing as 2.^

   1 squared is 1. i squared is i^2. i^2 divided by i is i. i is 1. 1+1 is 2. Now put the 2 infront of the i to make 2i.

Answer:

Its C I just did this

Step-by-step explanation

Answer:

First side = 12 units

Second side = 24 units

Third side = 16 units

Step-by-step explanation:

First, we can assign variables for each side of the triangle to make it easier:

A = side 1

B = side 2

C = side 3

The length of the second side of the triangle is twice the length of the first side, so we know that B is twice the length of A. We can represent this in an equation like this:

B = A * 2

The length of the third side is 4 units more than the first side. This tells us that C is going to be 4 more than A:

C = A + 4

And finally, the perimeter of the triangle is 52 units. Since the perimeter is just all the sides added together, we can create this equation:

A + B + C = 52

To start solving for lengths, I'm going to plug in the first two equations we got into the third equation:

A + B + C = 52

A + (A * 2) + (A + 4) = 52

1A + 2A + 1A + 4 = 52

4A + 4 = 52

4A = 48

A = 12

Now that we know what A is, we can solve for the other two variables:

B = A * 2

B = 12 * 2

B = 24

C = A + 4

C = 12 + 4

C = 16

Now we have all three variables, just don't forget what the variables represent (first side, second side, third side).

Answer:

Yes, they do.

Step-by-step explanation:

They both pass through the same points of -2 on the x and y axis.

Answer:

There is no distance between them

Step-by-step explanation:

For a 30 ft electric line to be placed between two 20ft electric poles, it would take 15 ft of the electric line to go down to about 5 ft above the ground and another 15 ft of the line to go to the top of the second electric pole. This means that a total of 30ft (15 ft + 15 ft) electric line would be needed which is all the cable we have.

For this to be possible then the poles must be adjacent to each other (i.e. no distance between them).

Answer:

- 2

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 2, - 1 ] , then

f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )

f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus

average rate of change = [tex]\frac{5-7}{-1-(-2)}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

Answer:

The coordinates of the images are P' (-4, -1), Q' (2, -1), R' (2, -4)

Step-by-step explanation:

If the point (x, y) is translated horizontally h units and vertically k units, then its image is (x + h, y + k) and the rule of translation is T (x + h, y + k)

∵ The vertices of the polygons are P (-5, 4), Q (1, 4), R (1, 1)

∵ The rule of translation is (x, y) → (x + 1, y - 5)

→ That means add each x-coordinate by 1 and subtract each

   y-coordinate by 5

∴ P' = (-5 + 1, 4 - 5)

∴ P' = (-4, -1)

∴ Q' = (1 + 1, 4 - 5)

∴ Q' = (2, -1)

∴ R' = (1 + 1, 1 - 5)

∴ R' = (2, -4)

∴ The coordinates of the images are P' (-4, -1), Q' (2, -1), R' (2, -4)
