NO JOKE 70 POINTS!!!!!!!! I WILL GIVE BRANLIEST AND RATE!!!! MATH EXPERTS COME HELP!!! AT LEAST TAKE A LOOK!!! LIKE WHERE ARE TH

E GENIUSES!!EASY I AM JUST DUMBREAD THIS AND THEN ANSWER THE QUESTION
READ THIS THEN ANSWER THE QUESTION:
There are so many items for sale in our world! Some of the items you can buy will appreciate in value. This means that as time passes, the value of the item increases. If you decide to sell the item at a later time, you should be able to sell it for more than you paid. Some common examples of items that appreciate in value include houses, stocks, and some types of art.
Other items you can buy will depreciate in value. This means that as time passes, the value of the item decreases. If you decide to sell the item at a later time, you will likely have to sell it for less than you paid for it. Cars, game systems, and jewelry are examples of items that usually depreciate as time passes. The majority of items that depreciate never reach a value of $0. Their worth attains some minimum, positive value that is greater than $0 and then their price stabilizes.
In 1981, IBM manufactured and sold one of the first personal computers. The machine was called the IBM Personal Computer (PC) 5150 and the full model retailed for $3,000. Similar to modern technology, the value of this item depreciated over time. The function that models how the PC 5150 depreciated as time passed is , where x is the number of years after 1981 and f(x) is the value of the PC 5150.

3. Which method: graphing, factoring, special patterns, or using the quadratic formula, is best for finding the zeros of the depreciation function? Explain.

4. use your answer from question 3 to find the exact values of the zero of the description function. if your initial plan from question 3 is not successful try a different method and adjust your respone to question 3, show your work

The width of a rectangle measures (3v-3w) centimeters, and its length measures (5v-9w) centimeters. Which expression represents
Alex17521 [72]

Answer: The Perimeter of the rectangle, P= 16v −24w

Step-by-step explanation:

Perimeter of a rectangle  = 2( L +W) =   2L + 2W

The width of a rectangle is given as  (3v-3w) centimeters,

its length is given as (5v-9w) centimetres

The Perimeter,P will now be  = 2L + 2W

P=2( 3v-3w) + 2( 5v-9w)

P=6v  −6w + 10v  - 18 w

 adding like terms

P=6v + 10v  −6w −18 w

P= 16v −24w

Two boys on bicycles, 45 miles apart, began racing directly toward each other. The instant they started, a fly on the handle bar
BlackZzzverrR [31]

Complete question is: Each bicycle have speed 10 mi/h and fly flies at 21 mi/h. How far the fly flies?

Answer:

47.25 mi

Step-by-step explanation:

The relative velocity of the bicycles is 10+10 = 20 mi/h

Time in which the two bicycles meet:

t=\frac{45}{20} = 2.25 h

Distance covered by fly:

d=vt\\d=21mi/h\times 2.25h \\d=47.25 mi

11.<br>The domain of f(x) is [4, 5, 6]. If f(x) = 3x + 2, what is the range?​
grigory [225]

Answer:

The range of the function is:

Range R = {14, 17, 20}

Step-by-step explanation:

Given the function

f(x) = 3x + 2

We also know that range is the set of values of the dependent variable for which a function is defined.  

In other words,  

  • Range refers to all the possible sets of output values on the y-axis.

We are given that the domain of the function is:

Domain D = {4, 5, 6}

Now,

substituting x = 4 in the function

f(4) = 3(4) + 2

f(4) = 12 + 2

f(4) = 14

substituting x = 5 in the function

f(5) = 3(5) + 2

f(5) = 15 + 2

f(5) = 17

substituting x = 6 in the function

f(6) = 3(6) + 2

f(6) = 18 + 2

f(6) = 20

Thus, we conclude that:

at x = 4, y = 14

at x = 5, y = 17

at x = 6, y = 20

Thus, the range of the function is:

Range R = {14, 17, 20}

The volume of a cone is 1540cm³. If its radius is 7cm, calculate the height of the cone. (Take pi = 22/7)
Ann [662]

Answer:

h=30

Step-by-step explanation:

Volume of a cone=1540cm^{3}, Radius=7cm.

The height of a cone=h

When we need to find the height of a cone, we can use the formula of the volume of a cone, which is \frac{1}{3} \pi r^{2} h to find the height of a cone.

1540cm^{3} =\frac{1}{3}\pi r^{2}  h

Put the pi value=22/7 and the value of radius which is 7 cm into the formula.

1540cm^{3}=\frac{1}{3}*\frac{22}{7}  7^{2}h

1540cm^{3} =\frac{154}{3}h

Move \frac{154}{3} to another side. 1540 divided by  \frac{154}{3} to calculate what is the value of h, h is the height of a cone. Like this.

\frac{1540cm^{3} }{\frac{154}{3} } =h

30=h

Rearrange the h.

h=30

I hope you will understand my solution and explanation. If you still cannot get the point, you can ask me anytime! Thank you!

a square dance set requires 4 couples 8 dancers with each couple standing on one side of a square. There are 250 people at a squ
sveta [45]

Given:

1 set requires 4 couples 8 dancers.

Total number of people at a square dance = 250.

To find:

The greatest number of sets possible at the dance.

Solution:

We have,

Total people = 250

1 set = 8 people.

\text{Number of possible sets}=\dfrac{\text{Total people}}{\text{People required for 1 set}}

\text{Number of possible sets}=\dfrac{250}{8}

\text{Number of possible sets}=31.25

Number of possible sets cannot be a decimal or fraction value. So, approx. the value to the preceding integer.

\text{Number of possible sets}\approx 31

Therefore, the number of possible sets at the dance is 31.
