the account was first opened. Determine the average rate of change of the account value from t=0 to t=5. Express your answer to the nearest cent.

Answer: x = 2

Step-by-step explanation:

3x - 5 = 1

add 5 to both sides

3x - 5 (+5) = 1 (+5)

3x = 6

divide by 3 on both sides

3x/3 = 6/3

x = 2

Step-by-step explanation:

The number of miles in the taxi ride is 10

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

Dalvin took a taxi from his house to the house. The taxi company charged a pick-up fee of $4.80;

The fare per mile is $2

The total fare was $30.80, not including the tip;

Let the number of mile is x

Total fare = pick up fee + fee per mile

30.80 = 4.80 + 2x

2x = 26

x = 13

Therefore, the number of miles by algebra Dalvin took a taxi will be 13

y = 4 is the equation of the line that represents Saturn Avenue given that Christopher decides that another road to be named Saturn Avenue is needed that will go past the cleaners and be perpendicular to Planet Drive. This can be obtained by using the formula for finding the equation of the line.

Equation of a line can be determined using the formula,

y = mx + c

where m is the slope of the line and c is the y - intercept.

m = rise/run = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

Here in this question draw the line passing through cleaners and perpendicular to Planet Drive.

The point where x = 0 is (0, 4)

This means that y - intercept is 4

By considering two points on the line we can find the slope of the equation,

Consider the points (8, 4) and (16, 4)

m = rise/run = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

m = (4 - 4)/(16 - 8) = 0/8 = 0

So we got that,

Putting in the equation of line we get,

y = mx + c

⇒ y = (0)x + 4 ⇒ y = 4

Hence y = 4 is the equation of the line that represents Saturn Avenue given that Christopher decides that another road to be named Saturn Avenue is needed that will go past the cleaners and be perpendicular to Planet Drive.

The correlation coefficient r between the two data sets is 0.33

From the table of values, we make use of the following representations:

Using the above representations, we can now plot our data values in the Excel software

From the Excel application, we have the following summary:

X Values

∑ = 424

Mean = 21.2

∑(X - Mx)2 = SSx = 101.2

Y Values

∑ = 151.8

Mean = 7.59

∑(Y - My)2 = SSy = 8.238

X and Y Combined

N = 20

∑(X - Mx)(Y - My) = 9.54

R Calculation

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

This gives

r = 9.54 / √((101.2)(8.238))

Evaluate

r = 0.3304

The maximum height of the ball after its third bounce is equal to 3.568 feet.

In this question we are aware that the maximum height reached by the ball decreases linearly after each bounce. To determine that height, we must take advantage of the recursive formula described in statement:

n = 0

a₀ = 10 ft

n = 1

a₁ = 0.85 · 10 - 1

a₁ = 8.5 - 1

a₁ = 7.5 ft

n = 2

a₂ = 0.85 · 7.5 - 1

a₂ = 5.375 ft

n = 3

a₃ = 0.85 · 5.375 - 1

a₃ = 3.568 ft

Loc and Reza together will finish the entire mowing process on the lawn at 1:14 p.m.

Loc mow the total area in 20 mins.

So, his pace is 1 lawn / 20 minutes or 1/20th of a lawn each minute.

Reza's pace is 1 lawn / 30 minutes, or 1/30th of a lawn each minute because he can mow the grass in that amount of time.

Reza joins Loc after he has been mowing for 5 minutes. He can mow 1/20th of the grass in these 5 minutes, which is 5/20th of the lawn =1/4th lawn

There is currently just

1-1/4=3/4 of the lawn left to complete.

We may construct the following equation by assuming that they mow together for x mins:

1/20x + 1/30x = 3/4 [amount done by Loc + Reza = total amount]

⇒(3x+2x)/60x = 3/4

⇒5x/60 = 3/4

⇒x/12= 3/4

⇒4x=36

⇒x= 9 mins

So, when they collaborate, they can complete the lawn in 9 minutes.

Hence, Loc mows alone for 9+5 mins = 14 mins

Therefore, it is concluded that starting at 1 p.m they finish the mowing at 1:14 p.m.

Answer:

2400 mm^2.

Step-by-step explanation:

The ratio of their areas = ratio of the squares of their sides.

So x / 7350 = 40^2 / 70^2   where x is area of smaller hexagon.

x = 7350 * 40^2 / 70^2

= 2400 mm^2.

The area of the smaller hexagon is found to be 2,400 mm², given the two hexagons are similar. Hence, 4th option is the right choice.

The areas of two similar figures are in the ratio which is equal to the square of the ratio of their corresponding sides.

If we have two figures A and B, and they are similar, then we can say that:

(Area of A)/(Area of B) = {(Side of A)/(Side of B)}².

In the question, we are informed that the two hexagons are similar in shape.

We are asked to find the area of the smaller hexagon, given the larger hexagon has an area of 7350 mm².

As the two hexagons are similar, we can show that:

(Area of the smaller hexagon)/(Area of the larger hexagon) = {(Side of the smaller hexagon)/(Side of the larger hexagon)}².

The side of the smaller hexagon is given to be 40mm, whereas the corresponding side of the larger hexagon is given to be 70 mm.

Thus, we can show that:

(Area of the smaller hexagon)/7350 = {40/70}²,

or, Area of the smaller hexagon = (16/49)*7350 = 16*150 mm² = 2400 mm².

Thus, the area of the smaller hexagon is found to be 2,400 mm², given the two hexagons are similar. Hence, 4th option is the right choice.

The coordinate pair that represents the volume and cost of the extra-large size is (24, 8).

A coordinate plane is a plane that can be used to represent the position of a point. The plane consists of x-axes and y-axes. The position of a point is referenced from the origin.

The small size of a pizza is represented by the coordinate pair (8, 4) ⇒ (volume, cost)

Since the volume of the extra-large size will have three times the volume of the small size, hence:

Volume of extra-large size = 8 * 3 = 24

The cost of an extra large is twice as much as the small size, hence:

Cost of extra large = 4 * 2 = 8

Let the number of hours after 1pm at which faster train will overtake slower train be x.

At overtaking point,

Distance travelled by slower train = Distance travelled by faster train

Given :

On equating distances we get

40 x ( x + 20) = 60 x (x)

40x + 80 = 60x

To form the first 18 terms, we must combine the following two sequences:

Any combination of these two sequences will yield a valid case in which no two 0's and no three 1's are adjacent

So we will combine identical 2-term sequences with identical 3-term sequences to yield a total of 18 terms, we get:
