Gwar [14]3 years ago
3 0

Answer:

see the explanation

Step-by-step explanation:

<u><em>The correct question is</em></u>

Use the discriminant to determine how many solutions are possible for the following equation (show  work).

5x^2-3x+4=0

we know that

The discriminant for a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

D=b^2-4ac

If D=0 then the equation has only one real solution

If D>0 then the equation has two real solutions

If D<0 then the equation has no real solutions (two complex solutions)

in this problem we have

5x^{2} -3x+4=0  

so

a=5\\b=-3\\c=4

substitute

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

D=-71

so

The equation has no real solutions, The equation has two complex solutions

therefore

I know there are___No____

real solutions to the equation in problem 4 because  ___the discriminant is negative___

Mattie is making a collar for her dog. She needs to buy some chain,a clasp, and a name tag. She wants the chain to be 40 centime
Fantom [35]

Answer:the total cost of the collar is $5.11

Step-by-step explanation:

To make a collar for her dog, she needs to buy some chain,a clasp, and a name tag.

The length of the chain that she wants to buy is 40 centimeters.

1000 centimeters = 1 meter

40 centimeters = 40/1000 = 0.04 meters.

One meter of chain costs $9.75. Therefore, 0.04 meters of chain would cost

0.04 × 9.75 = $0.39

The clasp is $1.29 and the name tag is $3.43. Therefore, the total cost of the collar would be

0.39 + 1.29 + 3.43 = $5.11

The perimeter, P, of a rectangle is the sum of twice the length and twice the width.
LekaFEV [45]
The answer is P = 2(l+w) units.

This is because when you let the perimeter of the rectangle be P, the length of the rectangle be l and the width of the rectangle be w.

The information above can be expressed as the following equation,
P = 2l + 2w

You can then factorise out the common factor, 2.
P = 2(l+w)

Thus, the answer is P = 2(l+w) units.

How to solve a quadratic problem
Ivenika [448]
Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring.
