A mercury thermometer records a temperature of 8 degrees Fahrenheit at 10:00am.If the Temperature drops by 3 degrees Fahrenheit every hour,what will be the Temperature by 2:00pm of the same day
Given:
Temperature at 10:00 am = 8 degrees Fahrenheit
Temperature drops by 3 degrees Fahrenheit every hour.
To find:
The temperature by 2:00pm of the same day.
Solution:
Let y be the temperature after x hour after 10:00 am.
The temperature at 10:00 am is the initial temperature.
So, y-intercept of the linear function is 8.
Temperature drops by 3 degrees Fahrenheit every hour.
So, slope of linear function is -3. Here, negative sign represents the decrease in the temperature.
Slope intercept form of a linear function is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
Substitute m=-3 and y=8 in the above equation.
[tex]y=-3x+8[/tex]
Difference between 2:00pm and 10:00 am is 4 hours. So, substitute x=4 in the above equation.
[tex]y=-3(4)+8[/tex]
[tex]y=-12+8[/tex]
[tex]y=-4[/tex]
Therefore, the temperature by 2:00pm of the same day is -4 degrees Fahrenheit.
determine the rate of change (slope) and starting point (y-intercept)
Answer: slope = 1, y intercept = 3
Step-by-step explanation:
The line crosses the y axis at 3 and when you calculate rise over run, you get 1, so the slope is 1.
A parking garage charges a 3.50$ base fee plus an hourly rate of 7.00$. If you have at most 21.50$ to pay for parking, how long can you park?
Answer:
You get a total of two hours of parking.
Step-by-step explanation:
First, you subtract the base fee of $3.50, which gives you $18.00. Then you subtract as many sevens there are in 18, which is two. And then your answer is shown, as two. Hope this helps!

5/6(−8/15)=
Answer:
-4/9
Step-by-step explanation:
I used a calculator.
5/6(−8/15) in simplest form is -4/9.
What is a fraction ?A fraction is written in the form of a numerator and a denominator.There are two types of fractions. One is proper fraction in which numerator is less than the denominator and another one is improper fraction in which denominator is less than the numerator.All fractions can be written in the form of p/q, where q ≠ 0 cause anything divided by 0 is undefined.
According to the given questions we have to multiply two fractions (5/6)(-8/15) which is
= -40/90.
= -4/9.

What is the complete factorization of the polynomial function over the set of complex numbers?
f(x)=x3−5x2+4x−20
Enter your answer in the box.
Answer:
[tex]x^3-5x^2+4x-20=(x-5)(x+2\mathbf{i})(x-2\mathbf{i})[/tex]
Step-by-step explanation:
Factorization of polynomials
Factor:
[tex]f(x)=x^3-5x^2+4x-20[/tex]
There are several techniques to factor polynomials. We'll use algebraic manipulation and common factor:
Separate in groups:
[tex](x^3-5x^2)+(4x-20)[/tex]
Factor out 4 from 4x-20:
[tex]=(x^3-5x^2)+4(x-5)[/tex]
Factor out [tex]x^2[/tex] from [tex]x^3-5x^2[/tex]
[tex]=x^2(x-5)+4(x-5)[/tex]
Factor out x-5:
[tex]=(x-5)(x^2+4)[/tex]
The roots of
[tex]x^2+4=0[/tex]
Are two complex numbers:
[tex]x=2\mathbf{i}, x=-2\mathbf{i}[/tex]
The complete factorization is:
[tex]\boxed{x^3-5x^2+4x-20=(x-5)(x+2\mathbf{i})(x-2\mathbf{i})}[/tex]

The winner of an election received 1 more than 3 times as many votes as his opponent received. Let w represent the number of votes the winner received. Let x represent the number of votes his opponent received. Which question could be used to find the number of votes the winner received if the number of votes his opponent received is known?
Answer:
w=3x+3Step-by-step explanation:
Given that the winners vote is represented by w
and that the opponents vote is represented by x
the question states that "The winner of an election received 1 more than 3 times as many votes as his opponent received"
Translated to mathematical expression we have
w=3(x+1)
w=3x+3
therefore the equation to find the number of votes his opponent received is known is
w=3x+3

The ratio of money in Terry's bank account to Faye's bank account was 3:5. Terry then put £220 in his account and Faye withdrew £300 from her account. They now had the same amount in their accounts. How much did they initially have altogether?
Answer:
Let the common ratio be x then
The amount of money in Terry' S Bank account will be 3x and that in Faye's Band Account will be 5x. So
According to question:
3x+£220=5x-£300
£220+£300=5x-3x
£520=2x
x=£210
Balance of Terry:3x
3×£210
£630
Balance of Faye=5x
5×£210
£1050
Money Altogether=£1050+£630
= £1680
Money Altogether in their account is £1680

((a^2b^2))/2ab
(ab)(ba)(ab)
Answer:
A. ((a^2)b)((b^2)a)
Step-by-step explanation:
A. ((a^2)b) ((b^2)a)
Open parenthesis
(a^2b)(b^2a)
a^3b^3
B. (a^4)b^4−ab
a^4b^4 - ab
C. ((a^2b^2))/2ab
(a^2b^2) / 2ab
D. (ab)(ba) (ab)
(a^2b^2)(ba)
Therefore,
a^3b^3 = ((a^2)b) ((b^2)a)
