Find f(0), f(3), and f(5) for the following function: f(x) = 3x + 1
f(0) =
f(3) =
f(5) =

Answers

Answer:

1, 10, 16

Step-by-step explanation:

Substitute the given values of x into f(x)

f(0) = 3(0) + 1 = 0 + 1 = 1

f(3) = 3(3) + 1 = 9 + 1 = 10

f(5) = 3(5) + 1 = 15 + 1 = 16

The U.S. population in 1910 was 92 million people. In 1990, the population was 280 million. This could either be a linear or exponential model. You will create both and then look at the true population increase and decide which model is closer the the true growth.

The actual U.S. population data (in millions) was:

Which model provides a better forecast for the U.S. population for the year 2030, linear or exponential or neither?

Question 5 options:

Linear model


Exponential model


Neither

Answers

Answer:

The linear model means that there is a uniform increase and in this case of US population from  92  million people in  1910  to  250  million people in  1990 .  

This means an increase of  250 − 92 = 158  million in  1990 -1910 = 80  years or   158 80 = 1.975  million per year and in  x  years it will become   92 + 1.975 x  million people. This can be graphed using the linear function  1.975 ( x − 1910 ) + 92 ,

graph{1.975(x-1910)+92 [1890, 2000, 85, 260]}

The exponential model means that there is a uniform proportional increase i.e. say  p %  every year and in this case of US population from  92  million people in  1910  to  250  million people in  1990 .  

This means an increase of  250 − 92 = 158  million in  1990 − 1910 = 80  years or  

p %  given by  92 ( 1 + p ) 80 = 250  which gives us  ( 1 +p ) 80 = 250 92  which simplifies to  p = ( 250 92 ) 0.0125 − 1 = 0.0125743  or  1.25743 % .  

This can be graphed as an exponential function  92 × 1.0125743 ( x − 1910 ) , which gives population in a year  y  and this appears as graph{92(1.0125743^(x-1910)) [1900, 2000, 85, 260]}

help me im having trouble on slopes

Answers

Answer:

The slope-intercept form of an equation looks like this: y=mx+b

The m stands for the slope and the b stands for the y-intercept.

We need two points from the line to write out this equation.

For example (-2,0) and (1,2)

Now that we have the slope, we can plug it into our equation: y= 2/3x + b

To get b, our y-intercept, we just need to plug in one of the points found and solve. For example (-2,0)

Now that we have both our m and b values, we can plug them in to get our equation: y=2/3x + 4/3

Step-by-step explanation:

[tex]m= \frac{y1-y2}{x1-x2} = \frac{0-2}{-2-1}[/tex]

[tex]m=\frac{-2}{-3} = \frac{2}{3}[/tex]

[tex]0=\frac{2}{3}(-2)+b[/tex]

[tex]0=-\frac{4}{3}+b\\ 0+\frac{4}{3}=-\frac{4}{3}+\frac{4}{3}+b\\ 0+\frac{4}{3}=b\\ \frac{0*3}{3}+\frac{4}{3}=b\\ \frac{4}{3}=b[/tex]

The perimeter of the rectangle below is 65 inches.
a. What is the value of x?
b. What are the dimensions of the rectangle?

Answers

Answer:

A :-) Given -

perimeter = 65 inches

Side ‘a’ = 2x

Side ‘b’ = 3 1 by 4x + 1

Solution -

Perimeter = 65

= a + b = 65

= 2x + 3 1 by 4x + 1 = 65

( 3 1 by 4 = 4 x 3 + 1 = 12 + 1 by 4

= 13 by 4 )

= 2x + 13 by 4x + 1 = 65

= 2x + 13 by 4x = 65 - 1

= 2x + 13 by 4x = 64

= 15 by 4 x = 64

= x = 64 x 4 by 15

= x = 256 by 15

= x = 17.06

.:. The value of x = 17.06.

X+2x-5+6= 0 How would you picture model this to solve for x?

Answers

Hey there!

x + 2x - 5 + 6 = 0

1x + 2x - 5 + 6 = 0

3x + 1 = 0

SUBTRACT 1 to BOTH SIDES

3x + 1 - 1 = 0 - 1

CANCEL out: 1 - 1 because that gives you 0

KEEP: 0 - 1 because that helps solve for the x-value

0 - 1 = -1

NEW EQUATION: 3x = -1

DIVIDE 3 to BOTH SIDES

3x/3 = -1/3

CANCEL out: 3/3 because that gives you 1

KEEP: -1/3 because it gives you the value of x

SIMPLIFY IT

x = -1/3

Therefore, your answer is: x = - 1/3

Read the article "Voyages of Discovery:"Centuries ago, countries sponsored explorers to set sail for parts unknown and return with tales of new lands. These explorations led the Europeans to discover North America. The ocean journey from England, France, or Spain to North America was 3,000 miles of unknown dangers, but it led to discoveries. Explorers made these treacherous voyages for three main reasons: religion, wealth, and competition. These voyages of discovery began in the eleventh century.Historical records indicate that Leif Eriksson, a Viking explorer, was the first man to reach North America around 1000. Leif is credited with landing along the coastline of present-day Newfoundland. A Viking settlement was established and occupied for several years before Eriksson left to return to his homeland. He died around 1020.Much later, Christopher Columbus left his homeland in 1492 to seek wealth in the form of trade items. The Italian explorer was destined for China but erred in direction and arrived on Watling's Island in the Bahamas. It was a long and dangerous journey. Upon arrival, Columbus dedicated the newly discovered land to the Spanish King and Queen of Aragon. Then, Columbus made three more voyages to North America in 1493, 1498, and 1502. To the very end, Christopher Columbus was adamant that he discovered a trade route to China. He denied ever being to North America.Credited with sailing around the southern tip of Florida, Spanish explorer Juan Ponce de Leon had several adventures in the New World. His journey around Florida occurred in 1513. At the time, he thought Florida was an island. When he returned to Florida in 1521, he was wounded by a poisoned arrow, which ultimately ended his life.Afterward, Hernando De Soto, a Spanish adventurer, left to explore present-day Florida in 1538. He and his men traveled thousands of miles through the South. They were the first Europeans recorded to have crossed the Mississippi River in 1541.Sir Walter Raleigh was a soldier, a writer, and a friend of the Queen of England. Around 1587, he sent English colonists to a region later called Virginia. The colony is believed to have been located in North Carolina. Since the people arrived together, their previous lifestyle and beliefs were transplanted to the New World.Finally, Rene Robert de La Salle was French. Historical data credits de La Salle as being the first explorer to traverse the Mississippi to its mouth at the Gulf of Mexico. He claimed the land that bordered the Mississippi River (about a third of present-day United States) for France on April 9, 1682. He built numerous forts along the route, but the settlers were often terrorized by the natives.These brave explorers from England, France, and Spain have left their legacy. As a result of their adventures, many people now enjoy North America's religious diversity, natural resources, and independence.What is the overall structure of this text?
