Which equation is not a quadratic equation?

Mathematics
1 answer:
BabaBlast [244]3 years ago

A quadratic equation is usually in the form:

ax^{2} +bx +c

where a, b and c are the coefficients of the expression and a ≠ 0. 

If a = 0, the equation becomes a linear expression and is no longer quadratic.

Hence, in the above options; y = 5x -2 is the only one that is not a quadratic equation.

Answer:

<h2>Angle X; 39</h2><h2>Angle Y; 129</h2>

Step-by-step explanation:

180-90

90

This gives us the measurement of 51+x.

90-51

39

This is x as well as the angle that is across from it.

x+90=y

39+90=129

y=129.

to find the last angle, we add 90 to 51. This gives us 141.

So, now we add up all of the angles to double check everything. If they all add up to 360 then we are correct.

39+39+51+90+141=

360.

This means that we have solved everything correctly and that these are the correct answers.

I know that this is really confusing but the answers that you need are at the top so hopefully this helped!

Tema [17]

The preparation of the Sales section of the income statement for Blue Spruce Corp. is as follows:

BLUE SPRUCE CORP.

<h3>Income Statement</h3>

For the year ended October 31, 2022

Sales Revenue                         $908,400

Sales Returns and Allowances  (20,900)

Sales Discounts                           (14,700)

Net sales revenue                  $872,800

<h3>How makes up the net sales revenue?</h3>

The net sales revenue represents the gross revenue minus sales returns and allowances and sales discounts.

In most jurisdictions, the sales discount account is reported on the income statement as a contra revenue account.  This implies that sales discounts are directly deducted from the gross sales and do not appear in the expense section nor the notes to the sales or revenue.

<h3>Data and Calculations:</h3>

Sales Revenue $908,400

Freight-Out $12,600

Sales Returns and Allowances $20,900

Sales Discounts $14,700

Thus, the preparation of the sales section of the income statement for Blue Spruce Corp. shows a net sales revenue of $872,800.

Special air bags are used to protect scientific equipment when a rover lands on the surface of Mars. On Earth, the function appr
Tema [17]
The acceleration due to gravity on earth is g = 32.174 ft/s².
Therefore on Mars, 
g = (2/3)*32.174 = 21.45 ft/s²

When an object falls from rest over a distance h, the final velocity, v, obeys the equation
v² = 2gh
or
v = √(2gh)

Therefore, given h = 15 ft, the impact velocity on Mars is
v = √(2*21.45*15) = 25.367 ft/s
The closest given answer is 25.3 ft/s

Answer:  B) 25.3 ft/s
