Solve for F.

f divided by 22.3=6.6

Answers

Answer 1
Answer: so if you have x/y=z then you multiply both sides by y then you get
(xy)/y=zy
x(y/y)=zy
x(1)=zy
x=zy and cancel the fraction so


f/22.3=6.6
multiply both sides by 22.3 to get rid of fraction
f=147.18

Answers

Answer:

slope is 3 and -1

Step-by-step explanation:

Answer:https: y+3x-8

Step-by-step explanation: first: put your first point at -8

second: then from the point at -8, go up three times, and over to your right one time

now do that however many times you need to

explanation:

- the y-intercept is the initial value which is -8. the line must pass through -8 so you would start your line at -8

- your slope is 3x. slope is  so you rise 3 time and over 1 time

y = -x – 4 -4.0

y-intercept = -4/1 = -4.00000

What is linear equation in one variable and how to solve such equations?

Linear equation are the equation in which degree of the variable is one and only one variable is present in the equation. To solve is to find the value of the variable and to do that we first separate the variable from the constant and then find the value of the variable

We are given an equation

√(x+20) =9

To solve the equation is to find the value of the variable x and to do that  first we take is to square the equation both sides

We get

x + 20 = 81

Now we separate the variable and the and the constant to find the value of the variable we get

x = 61

Hence the correct answer is 61 and correction option is option b)

Answer:

x=61

Step-by-step explanation:

There's a website called "symbolab.com" that I use to figure out problems like this easily. :) It has a bunch of math-related calculators and graphing stuff.

John, Sally, and Natalie would all like to save some money. John decides that itwould be best to save money in a jar in his closet every single month. He decides
to start with $300, and then save $100 each month. Sally has $6000 and decides
to put her money in the bank in an account that has a 7% interest rate that is
compounded annually. Natalie has $5000 and decides to put her money in the
bank in an account that has a 10% interest rate that is compounded continuously.

How much money will sally have in 10 years?

What type of exponential model is Natalie’s situation?

Write the model equation for Natalie’s situation

How much money will Natalie have after 2 years?

How much money will Natalie have after 10 years

Answers

Answer:

Part 1) John’s situation is modeled by a linear equation (see the explanation)

Part 2)  y=100x+300

Part 3) \$12,300

Part 4) \$2,700

Part 5) Is a exponential growth function

Part 6) A=6,000(1.07)^(t)

Part 7) \$11,802.91

Part 8)  \$6,869.40

Part 9) Is a exponential growth function

Part 10) A=5,000(e)^(0.10t)    or  A=5,000(1.1052)^(t)

Part 11)  \$13,591.41

Part 12) \$6,107.01

Part 13)  Natalie has the most money after 10 years

Part 14)  Sally has the most money after 2 years

Step-by-step explanation:

Part 1) What type of equation models John’s situation?

Let

y ----> the total money saved in a jar

x ---> the time in months

The linear equation in slope intercept form

y=mx+b

The slope is equal to

m=\$100\ per\ month

The y-intercept or initial value is

b=\$300

so

y=100x+300

therefore

John’s situation is modeled by a linear equation

Part 2) Write the model equation for John’s situation

see part 1)

Part 3) How much money will John have after 10 years?

Remember that

1 year is equal to 12 months

so

10\ years=10(12)=120 months

For x=120 months

substitute in the linear equation

y=100(120)+300=\$12,300

Part 4) How much money will John have after 2 years?

Remember that

1 year is equal to 12 months

so

2\  years=2(12)=24\ months

For x=24 months

substitute in the linear equation

y=100(24)+300=\$2,700

Part 5) What type of exponential model is Sally’s situation?

we know that    

The compound interest formula is equal to  

A=P(1+(r)/(n))^(nt) 

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

P=\$6,000\n r=7\%=0.07\nn=1

substitute in the formula above

A=6,000(1+(0.07)/(1))^(1*t)\n  A=6,000(1.07)^(t)

therefore

Is a exponential growth function

Part 6) Write the model equation for Sally’s situation

see the Part 5)

Part 7) How much money will Sally have after 10 years?

For t=10 years

substitute  the value of t in the exponential growth function

A=6,000(1.07)^(10)=\$11,802.91 

Part 8) How much money will Sally have after 2 years?

For t=2 years

substitute  the value of t in the exponential growth function

A=6,000(1.07)^(2)=\$6,869.40

Part 9) What type of exponential model is Natalie’s situation?

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^(rt) 

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

P=\$5,000\nr=10\%=0.10

substitute in the formula above

A=5,000(e)^(0.10t)

Applying property of exponents

A=5,000(1.1052)^(t)

 therefore

Is a exponential growth function

Part 10) Write the model equation for Natalie’s situation

A=5,000(e)^(0.10t)    or  A=5,000(1.1052)^(t)

see Part 9)

Part 11) How much money will Natalie have after 10 years?

For t=10 years

substitute

A=5,000(e)^(0.10*10)=\$13,591.41

Part 12) How much money will Natalie have after 2 years?

For t=2 years

substitute

A=5,000(e)^(0.10*2)=\$6,107.01

Part 13) Who will have the most money after 10 years?

Compare the final investment after 10 years of John, Sally, and Natalie

Natalie has the most money after 10 years

Part 14) Who will have the most money after 2 years?

Compare the final investment after 2 years of John, Sally, and Natalie

Sally has the most money after 2 years
