What is the question?????

Answer:

b

Step-by-step explanation:

The average rate of change in the value of the account for the first 3 years is,  $3.15/year. So Option C  is correct.

Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.

So formula for the rate is,

m = change in one quantity/change in another quantity = Δy/Δx

The average rate of change in the value of the account for the first 3 years can be calculated as follows:

Let t = 0 be the time when the account is opened,

and t = 3 be the end of the third year.

The value of the account at t = 0 is V(0) = 30,

and the value of the account at t = 3 is

V(3) = 30(1.05)³

The average rate of change in the value of the account over the first 3 years is given by the formula:

⇒ (V(3) - V(0)) / (3 - 0)

⇒ (30(1.05)³ - 30) / 3

⇒  $3.15/year

Hence, the average rate of change in the value of the account over the first 3 years is approximately $3.15/year

Answer:

5yards

Step-by-step explanation:

Area of the parallelogram = Base * Height

Given

Area = (5x+20)yd²

Base = (x+4)yd

Required

height

Substitute into the formula

5x+20 = x+4 * Height

Height = 5x+20/x+4

Height = 5(x+4)/x+4

X+4 cancels out to have;

Height = 5

Hence the height of the parallelogram is 5yards

Answer:

X=5

15x=75

Step-by-step explanation:

Answer:

x=35

Step-by-step explanation:

Volume = rule area × height

__________________________

The rule is circle and the area of the circle finds using following formula :

Circle area = pi × radius^2

Circle area = 3.14 × 1^2

Circle area = 3.14

___________________________

Volume = 3.14 × 10

Volume = 31.4 in^3

The volume of cylinder having diameter 1 inches and height be 10 inches be 31.4 cubic inches.

Volume is amount of substance a container can hold in its capacity. Volume of cylinder is π[tex]r^{2} h[/tex] in which r is radius and h is height of cylinder.

We have been given that the diameter of cylinder be 2 inches and height be 10 inches.We have to find the volume of cylinder.

Volume of cylinder=π[tex]r^{2} h[/tex]

Radius=2/2

=1 inch

Now put the value of radius and height in the formula of volume.

Volume=3.14*1*10

=31.4 cubic inches.

Hence the volume of cylinder is 31.4 inches.

Answer:

Hooverville

Step-by-step explanation:

The Hooverville has lower median temperature.

A box and whisker plot is a method for abstracting a set of estimated data using an interval scale. Another name for it is simply a box plot. Most of the time, these are used to interpret data. It is one kind of graphical method that shows how the data in the dataset changes. The histogram can also be used to show the data. However, the histogram provides an adequate display. Since multiple sets of data can be displayed in the same graph, a box and whisker diagram will provide additional information, making it superior to a histogram.

Given Box and Whisker Plot of two cities which show's the  noon temperature each day,

From the graph Median of Hooverville is 36 and

median of Deeson City is 38

we can say that Hooverville has lower median temperature.

Hence the lower median temperature is of Hooverville.

Step-by-step explanation:

Just did it on edge 2021

The translation rule will be (x+8 , y+4).

A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

When we scale a triangle by some factor, neither its shape nor size change. The image corresponds to the previous image.

The horizontal translation of x coordinate is either horizontally right or horizontally left depending on the positive or negative value of x - coordinate.

Depending on the positive or negative value of the y - coordinate, the y coordinate is translated vertically up or down.

Here (8 ,4) shows there is shifting Horizontally right (x+ 8) and there is shifting Vertically up (y + 4).

Can you solve for x and answer?

The value of expression sin C - cos C is,

⇒ r - s

Triangle is a three sided polygon, which has three vertices and three angles and which has sum 180 degrees.

Given that;

In right triangle ABC,

⇒ m∠ B ≠ m∠ C.

Let us assume that,

⇒ sin B = r

And, cos B = s.

Now, We get;

sin B = rh / h

        = r

And, cos B = sh / h

                 = s

Hence, We can formulate;

sin C = sh / h = s

cos C = rh / h = r

Thus, We get;

⇒ sin C - cos C

⇒ r - s

Therefore, The value of expression sin C - cos C is,

⇒ r - s
