Answer:

f(0) = 4 g(-4) = - 2

Step-by-step explanation

This is what I think the answer is. Pls, let me know if it is correct or not!

Whenever you see f(x), g(x), m(x) literally anything with a letter then (x) think of it as y.

So when you see f(0) think y, but the only difference between f(x) and y is that f(x) is telling you what the x value is.

In that case, when you see f(0) it is basically asking when x=0 what is the Y value.

So then you would look on your graph at the f(x) graph, which is the linear graph (the straight-line graph), and look for x=0 (which is the origin point

(0,0)) after you find x=0 go straight up until you find where the line intersects. in this case, it is 4.

Then you would do the same for g(-4).

So then you would look on your graph at the g(x) graph, which is the graph that looks like a v shape, and look for x=-4 (which is to the left 4 spaces) after you find x=-4 go straight down until you find where the line intersects. in this case, it is -2.

The resquest of the y'+6y=e^4t, y(0)=2

kotegsom [21]

This is a linear differential equation of first order. Solve this by integrating the coefficient of the y term and then raising e to the integrated coefficient to find the integrating factor, i.e. the integrating factor for this problem is e^(6x).
Multiplying both sides of the equation by the integrating factor: 

(y')e^(6x) + 6ye^(6x) = e^(12x) 

The left side is the derivative of ye^(6x), hence 

d/dx[ye^(6x)] = e^(12x) 

Integrating 

ye^(6x) = (1/12)e^(12x) + c where c is a constant 

y = (1/12)e^(6x) + ce^(-6x) 

Use the initial condition y(0)=-8 to find c: 

-8 = (1/12) + c 
c=-97/12 

Hence 

y = (1/12)e^(6x) - (97/12)e^(-6x)

Is 1/3 greater than 5/6

Harman [31]

1/3 or 5/6

Lets make the fractions into decimals. To make a fraction into decimal you have to divide the numerator by the denominator. The numerator is the top part of a fraction and the denominator is the bottom part of the fraction.

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

Calculations

1/3
1 ÷ 3 = 0.3333....

5/6
5 ÷ 6 = 0.83333...

0.83333... is greater then 0.3333.....
Therefore 5/6 is greater then 1/3
1/3 is smaller then 5/6

A skyscraper has 49 floors there are 26 offices on each of the bottom 31 fours the top 18 floors each have 38 officers about how

Anettt [7]

Answer:

903 offices

Step-by-step explanation:

Total number of officers in the sky scraper

= 26 + 31 + [(49-2)×18]

= 26 + 31 + 846

= 903 offices

Find all values of t such that t+4/t+5 = t-5/2t

ivolga24 [154]

Answer:

t cannot be -5 or 0 because these cause a 0 in the denominator and you cant divide by 0 that I'm aware of

What are the correct intermediate steps of the following data set when it is being sorted with the bubble sort? 15, 20, 10, 18

love history [14]

Answer:

A. 15,10,20,18 -- 15,10,18,20 -- 10,15,18,20

Step-by-step explanation:

Bubble sorting can be defined as a technique or methodology whereby numbers that are not in their proper order are sorted into proper order that is from smallest to highest( increasing to decreasing order).

The method of bubble sorting involves the shuffling or swapping of adjacent numbers until the numbers are well sorted or arranged.

In the above question, we were given, a set of numbers:

15, 20, 10, 18

Step 1

20 is adjacent to 10

20 > 10

hence we swap

= 15,10,20,18

Step 2

From, 15,10, 20,18

20 is adjacent to 18

20 > 18

hence we swap

= 15,10,18,20

Step 3

From step 2, which gave us 15,10,18,20

15 us adjacent to 10

15 > 10

We swap

= 10,15,18,20

Hence,

15, 20, 10, 18 -- 15,10,20,18 -- 15,10,18,20 -- 10,15,18,20

Therefore, Option A is the correct option.
