Determine the number of real solutions of -2x^2+5x-3=0

Mathematics
1 answer:
Tema [17]3 years ago
8 0

Answer:

Two distinct real solutions.

Step-by-step explanation:

Given the equation in the form ax^2+bx+c=0, you need to find the Discriminant with this formula:

D=b^2-4ac

For the equation -2x^2+5x-3=0 you can identify that:

a=-2\\b=5\\c=-3

Then, substituting these values into the formula, you get that the Discriminant is:

D=5^2-4(-2)(-3)

D=1

 Since D>0, then -2x^2+5x-3=0 has two distinct real solutions.

salantis [7]

Complete question

<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented </em>

<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a </em>

<em>variable, write an equation, and solve the problem.</em>

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16

Let the cost of green fees per person be y

If Luis and three friends went golfing, this means that 4 people went golfing.  The total cost of green fees for all of them will be $4y

If two of the friends rented clubs for $6 each, total amount spent will be $2(6)

The equation that models the statement will then be expressed as;

4y + 2(6) = 76\\

Solve for y

4y + 2(6) = 76\\4y+12 = 76\\4y = 76 - 12\\4y = 64\\y =\frac{64}{4}\\y = 16

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.

what trigonometric expression can be used to find the value of x? replace a and b with the correct values.
Margaret [11]

The trigonometric function that can be used to find the value of x is 12 / tan ( 25 ) . The correct values of a and b will be 12 and 25 resp . .

Given :

A right angle triangle , one angle = 25 ° and side opposite given angle = 12 units .

Trigonometric Formula for Tan θ

tan θ = perpendicular / base , tan θ = ( sin θ / cos θ ) , tan θ = ( 1 / cot θ ) .

where θ = 25 , perpendicular = 12 , base = x .

Substituting values in above first formula ,

tan 25 = 12 / x

Therefore , x = 12 / tan ( 25 ) .

Hence , a = 12 and b = 25 .
