HELP PLEASEEE!!!!!!! The population in Smalltown in 2010 was 56,382 people and is growing exponentially at a rate of 1.2 percent. Which of the following equations defines the population t years after 2010?

a. P= 56,382(1+0.12)^t
b. P= 56,382(1+0.012)^t
c. P= 56,382e^0.012t
d. P= 56382e^1.2t

Answers

Answer:

b. P = 56,382(1+0.012)^t

The equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

The population P after 2010 is an exponential growth function of the form:

[tex]P = P_{0} (1 + r)^t[/tex]

where P₀ is the initial population,

r is the annual growth rate as a decimal, and

t is the time in years.

Byu given information P₀ = 56,382,

r = 0.012, and

t is the number of years after 2010.

The equation that defines the population in Smalltown t years after 2010 is:

[tex]P = 56,382(1 + 0.012)^t[/tex]

Hence, equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

35. The distance between two cities on a map is 3.5 centimeters. The map uses a scale

in which 1 centimeter represents 20 kilometers. What is the actual distance

between these two cities in kilometers?

Answers

Answer:

The distance between two cities is 70 km.

Step-by-step explanation:

Given that,

The distance between two cities on a map is 3.5 centimeters.

It is also mentioned that the map uses a scale  in which 1 centimeter represents 20 kilometers.

We need to find the actual distance  between these two cities in kilometers.

1 cm = 20 km

3.5 cm = (3.5 × 20) km

= 70 km

Hence, the distance between two cities is 70 km.

1. The scale of a map is 1:1000. What are the actual dimensions of a
rectangle which appears as 4 cm by 3 cm on the map? What is the area
on the map in cm2 ?What is the actual area in m2?

Answers

Answer:

Step-by-step explanation:

4 cm × 1000 = 4000 cm = 40 meters

3 cm × 1000 = 3000 cm = 30 meters

A 4 cm by 3 cm  section on the map represents 40 m by 30 m.

area = 40 m × 30 m = 1200 m²

Given log34≈1.262 and log37≈1.771, what is the value of log3(167)?



Enter your answer in the box.

Answers

Answer:

0.753

Step-by-step explanation:

I just took the test lol

The value of log₃(⁷/₁₆) when log₃4 = 1.262 and log₃7 = 1.771 is;

log₃(⁷/₁₆) = -0.753

We are given;

log₃4 = 1.262

log₃7 = 1.771

We want to find log₃(⁷/₁₆)

Now, from properties of logarithm too, we have;

logₐ(x/y) = logₐx - logₐy

Thus;  log₃(⁷/₁₆) =  log₃7 -  log₃16

Also, we know that; logₐx² = 2logₐx

Thus; log₃16 =  log₃4²

log₃16 = 2log₃4

Thus; log₃(⁷/₁₆) = log₃7 - 2log₃4

Plugging in the relevant values gives;

1.771 - 2(1.262) = -0.753

Answers

Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack

number of packs of regular cards =r and the number of packs of foll cards = f

Cost of Regular card = 3.50

Cost of 'r' packs of regular card = 3.50r

Cost of Foil card = 4.50

Cost of 'f' packs of Foil card = 4.50f

Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20

The inequality becomes

3.50r + 4.50f <= 20

Name the steps of solving 5x+4=40

Answers

Answer:

Step-by-step explanation:

Simplifying

5x + -4 = 40

Reorder the terms:

-4 + 5x = 40

Solving

-4 + 5x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 5x = 40 + 4

Combine like terms: -4 + 4 = 0

0 + 5x = 40 + 4

5x = 40 + 4

Combine like terms: 40 + 4 = 44

5x = 44

Divide each side by '5'.

x = 8.8

Simplifying

x = 8.8
