Is xsquare+1/xsquare equal5 is quadratic or not

Mathematics
1 answer:
MAXImum [283]3 years ago
5 0

Answer:

Yes, it is a quadratic equation.

Step-by-step explanation:

<em>Let's solve it to make it a quadratic equation:</em>

=> \frac{x^2+1}{x^2} =5

=> x²+1 = 5x²

=> 5x²-x²-1 = 0

=> 4x²-1 = 0

<em>Comparing it with the standard form of quadratic equation i.e. </em>

ax^2+bx+c = 0

So, we get

a = 4 , b = 0 and c = -1

<u><em>So, yes. It is a quadratic equation and it is a pure quadratic equation since b is equal to 0.</em></u>

A is more because 1/4 is equal to 2/8 and 2/8 is less than 7/8 so you would have more than a minute
B is three minutes 2/8 goes into 7/8 three times

Brian bought a new air conditioning unit on his credit card. The unit had a base price of $435. Brian made no other purchases on
Svetlanka [38]

Answer:

D is the correct answer

Step-by-step explanation:

Given:

Unit base price: $435

Credit Card interest rate, i = 9.4% compounded monthly; i = 0.00783/month comp monthly

n = 1.5 years = 18 months

sales tax = 8.51%

First, determine the actual price of the unit by adding the sales tax to the base price of the unit:

$435 * (1 + 0.0851)

Actual price = $472.0185

So, the total amount paid by Brian should be higher than the actual price since he used his credit card. Use the formula from economics:

F = P (1+i)^n

F = $507.96

Therefore, the total amount paid by Brian is $507.96.

(Hope this helps can I pls have brainlist (crown) ☺️)

hi

5 000 * X ^(8) =  10 000

             x^(8) =  10 000 / 5000

             x ^(8)=  2

            x =  2^(1/8)

            x≈ 1.09

intrest rate must be  9%

Let the function f be defined as f(x)= 5x^2 - 7(4x+3). What is the value of f(3)
Katen [24]

Answer:

f(x) = -60 is your answer

Step-by-step explanation:

Plug in 3 for x

f(x) = 5x² - 7(4x + 3)

f(x) = 5(3²) - 7(4(3) + 3)

Follow PEMDAS. First, solve the parenthesis

3² = 9

4(3) + 3 = 12 + 3 = 15

f(x) = 5(9) - 7(15)

Multiply

f(x) = 45 - 105

Simplify. Subtract

f(x) = 45 - 105

f(x) = -60

f(x) = -60 is your answer
