The number of camera phones shipped globally can be modeled by the function y = 1.28e 1.31x where x is the number of years since 1997 and y is the number of camera phones shipped (in millions). How many camera phones were shipped in 2002?

Answers

Answer 1

Answer: 895 phones

Step-by-step explanation:

Given that :

The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997

y = number of camera phones ; x = number of years since 1997

The number of camera phones shipped in the year 2002 can be obtained thus ;

x = 2002 - 1997 = 5 years

y = 1.28e^(1.31 * 5)

y = 1.28e^6.55

y = 1.28(699.24417)

y = 895.03254

y = 895 phones

Step-by-step explanation:

Length, Area, and Volume Scale Factors

If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is [tex]a^2:b^2[/tex] and the scale factor of their volumes is [tex]a^3:b^3[/tex].

We are given the scale factor of the surface areas of two similar containers A and B as 4:25.

The length scale factor is

[tex]\sqrt{4}:\sqrt{25}=2:5[/tex]

The volume scale factor is: [tex]5^3:2^3[/tex] = 125:8 = 15.625

Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

An item is regularly priced at $58. It is now priced at a discount of 80% off the regular price

Answers

Answer: The discount price is $11.60. The discount is $46.40. (I didn't know which answer you wanted)

Step-by-step explanation: First, you need to find the discount. To do that, all you need to do is multiply 58 by 80/100 (this is still equal to 80%). You should get 46.40 (you might get 46.4 but it's the same thing), Then, subtract 46.40 form 58. You should get 11.60. So your final answer should be $11.60.

Use the drawing tool(s) to form the correct answer on the provided graph.
Consider the system of equations.



The first equation in the system is graphed below. Graph the linear equation on the coordinate plane and use the Mark Feature tool to place a point at the solution(s) of the system.

Answers

Answer:

(-7, 0) and (0, -7)

Step-by-step explanation:

Draw the graph of x = - y - 7.

Convert to the slope-intercept form (y = mx + b):

x = -y - 7      add y to both sides

x + y = -7     subtract x from both sides

y = -x - 7

This is the straight line equation. We only need two points to plot the graph.

Choose any value of x, put to the equation and calculate the value of y.

for x = 0:

y = -0 - 7 = -7 → (0, -7)

for x = -7:

y = -(-7) - 7 = 7 - 7 = 0 → (-7, 0)

Mark points in the coordinate system and draw a line.

The intersection points of the circle and the line are the solution.

Answer:

(-7, 0) and (0, -7)

Step-by-step explanation:

Draw the graph of x = - y - 7.

Convert to the slope-intercept form (y = mx + b):

x = -y - 7      add y to both sides

x + y = -7     subtract x from both sides

y = -x - 7

This is the straight line equation. We only need two points to plot the graph.

Choose any value of x, put to the equation and calculate the value of y.

for x = 0:

y = -0 - 7 = -7 → (0, -7)

for x = -7:

y = -(-7) - 7 = 7 - 7 = 0 → (-7, 0)

Mark points in the coordinate system and draw a line.

The intersection points of the circle and the line are the solution.

Three friends order a pizza for $14, a two-liter bottle of soda for $2.75, and a bag of chips for $2.15 They want to evenly split the total cost. Determine how much each person owes.

Answers

Answer:

$6.3

Step-by-step explanation:

Given that:

There are 3 friends who have ordered some eatables.

Price of one pizza = $14

Price of two-liter soda bottle = $2.75

Price of a bag of chips = $2.15

The price of all the items is split evenly.

To find:

How much each person owes i.e. the amount of money each person will have to pay?

Solution:

First of all, let us find the total amount to be paid for all the three items.

Total amount to be paid = $14 + $2.75 + $2.15 = $18.9

Now, this total amount is evenly split i.e. equally divided in three parts.

Let us divide the total amount by 3.

Therefore, share of each friend = [tex]\frac{\$18.9}{3} = \bold{\$6.3}[/tex]

Answers

In order to drive 643 miles at 65 mph, I believe it would take 9.9 hours. (It is 9.8923 not rounded to the nearest tenth btw lol) I hope this is right! :)

Answer:

9.9 hours, rounded to the nearest tenth hour.

Step-by-step explanation:

To calculate the time of travel, we must first divide the distance by the speed. Why, you ask? Because of this equation:

[tex]Speed\=\ \frac{distance}{time}[/tex]

Therefore, with a little bit of arrangement, we get:

[tex]Time\=\ \frac{distance}{speed}[/tex]

So, let's get on with it.

[tex]Time\=\ \frac{643 \ miles}{65 \ mph}[/tex]

[tex]Time\=\ 9.9 \ hours [/tex]

Finally, we have our answer: 9.9 hours, rounded to the nearest tenth.

An observational study of suburban towns reveals that towns with more dedicated park land tend to have higher median home prices. A real estate agent suggests that a town’s crime rate is a more accurate predictor of median home price.

What is the confounding variable in this study?

the median home price
the crime rate
the distance from a large city
the median home size

Answers

Answer:

the median home size.

Step-by-step explanation:

In this scenario, the confounding variable would be the median home size. This is because this factor is both a cause and effect of the median home prices. A bigger house would obviously be worth more than a smaller house so the house size affects the prices of the homes in the market. At the same time, the median home sizes can also cause an increase or decrease in crime rates as criminals are more likely to target homes that seem as though they have more valuables inside.

Given: tangent A = negative StartRoot 15 EndRoot What is the value of Tangent (A minus StartFraction pi over 4 EndFraction)?

Answers

Answer:

( √15 + 8)/7

Step-by-step explanation:

TanA = -√15

.we are to find tan(A-π/4).

In trigonometry

Tan(A-B) = TanA - TanB/1+ tanAtanB

Hence:

tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4

Substitute tan A value into the formula

tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4

tan(A-π/4) = -√15-1/1-√15

Rationalize

-√15-1/1-√15 × 1+√15/1+√15

= -√15-√225-1-√15/(1-√225)

= -2√15-15-1/1-15

= -2√15 -16/(-14)

= -2(√15+8)/-14

= √15 + 8/7

Hence the required value is ( √15 + 8)/7

Tim incorrectly says
that the solution of the system of equations is
x= -9, y= -4.

System of equations:
6x - 2y = -6
11 = y - 5x


a. What is the correct solution?
b. What error might Tim have made?

Answers

Answer:

a)First, solve and regroup

11=y-5x

y=11+5x.

Plug in:

6x-2(5x+11)=-6

6x-10x-22=-6

-4x-22=-6.

-4x=16

x=-4.

Plug it:

y=11+5(-4)

y=11-20

y=-9.

x,y=-4,-9.

b) The error Tim made is that he confused the x and y.

The correct answer is -4,-9.

He said it was -9,-4.

Hope this helps plz hit the crown ;D

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

6x-2y = -6...1

11= y-5x...2

(a) Rearranging the 2 equation;

11=y-5x

y=11+5x.

substituting in first equation;

6x-2(5x+11)=-6

6x-10x-22=-6

-4x-22=-6.

-4x=16

x=-4.

Now putting the value of x in second equation;

y=11+5(-4)

y=11-20

y=-9.

x,y=-4,-9.

(b) The error Tim made is; he confused the x and y.

The correct answer will be -4,-9.
