I need help on question 1 of symbolic representation

Mathematics

Step-by-step explanation:

Symbolic representation here means defining the function using variables such as x and y (or f(x)).

An example would be f(x) = 4x+3.

Here, we are given two points on the linear function (which is a line), namely

f(4)=5,  which implies P1(4,5) is a point P1 on the line, and

f(-7)=5, which implies P2(-7,5) is another point P2 on the line.

With the usual notation that

P1 has the coordinates (x1,y1)

P2 has the coordinates (x2,y2),

we see that

x1=4, y1=5

x2=-7, y2=5

which can be used in the standard equation for a line given two points P1 and P2:

m = slope = (y2-y1)/(x2-x1) = (5-5)/(-7-(4)) = 0/11 = 0

equation of the line

y = m(x-x1) + y1, which simplifies to

y = 0(x-4) + 5, which further simplifies to

y=5   (which is a horizontal line).

Answer:

f(x) = 0x + 5

Step-by-step explanation:

Lets use the slope formula to determine the slope of this graph:

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1} } \\\\m=\frac{5-5 }{4-(-7)} \\\\m=0

SO we know the slope is zero.

If we know the slope is zero, then the y intercept must be at 5.

So the equation would be:

f(x) = 0x + 5

Choose all options that apply. Which of the following are equal to 20%? | a) .25 b) 1/5 Oc) 1/10 d) .20
zloy xaker [14]

Answer:

b. and d.

Step-by-step explanation:

20 =  \frac{20}{100}  \\ 0.25  =  \frac{25}{100} \\  \frac{1}{5}  =  \frac{20}{100} \\  \frac{1}{10}  =  \frac{10}{100}  \\ 0.20 =  \frac{20}{100}

Gravano Engineering co has the following items appearing in its statement of financial position at the year end:
professor190 [17]

Based on the items appearing in Gravano Engineering's Statement of Financial Position at the year-end, the totals for the following are:

1. Non-current Assets = $192,000

2. Current Assets = $64,000

<h3>What is a Statement of Financial Position?</h3>

A Statement of Financial Position is a financial statement that shows an entity's assets, liabilities, and equity.

Assets are items owned by an individual or entity that generate current, future, or potential economic benefits.

Liabilities are financial obligations that an individual or entity owes creditors.

Equity is the difference between assets and liabilities, which refers to the financial benefits accruing to the stockholders.

<h3>Data and Calculations:</h3>

1. Trade payables                                    $39,000

2. Cash at bank                                         14,000

3. Motor vans                                           25,000

7. Trade receivables                              43,000            

8. Plant and equipment                        26,000            

9. Trademarks                                        28,000

10.   Fixtures and fittings                        17,000

11.   Mortgage on property                   45,000​

<h3>Current Assets:</h3>

2. Cash at bank                                          14,000

4. Inventories                                              7,000

7. Trade receivables                                43,000            

Total current assets =                           $64,000

<h3>Non-Current Assets:</h3>

3. Motor vans                                          25,000

6. Property                                              96,000

10.   Fixtures and fittings                         17,000

Total non-current assets =                $192,000

Thus, the total non-current assets are $192,000 and the current assets total $64,000.

Use the formula SA=6s2 , where SA is the surface area and s is the edge length of the cube, to solve this problem.
Irina-Kira [14]
Using the SA formula you'll have to substitute in the edge length for s.

SA = 6(312)²
SA = 584064

The surface area is 584,064 feet²

Hope this helps :)
