what are the solution(s) to the quadratic equation 50 – x2 = 0? x = ±2 x = ±6 x = ±5 no real solution

Answers

Consider the given quadratic equation 50-x^2=0

x^2-50=0

Comparing the given quadratic equation to the general equation ax^2+bx+c=0, we get a= 1, b=0 and c= -50

So, the solution to the quadratic equation is given by:

x = (-b \pm √(b^2-4ac))/(2a)

x = (-0 \pm √(0^2-4(1)(-50)))/(2)

x = (\pm √(200))/(2)

x = \pm \sqrt2 (5)

x = \pm 5\sqrt2

So, the solutions to the given quadratic equation are x = \pm 5\sqrt2.

c

Natalie wants to buy a shirt that costs $24. It is on sale for 20% off the original price. How much does she pay for the shirt? $19.20 $21.60 $26.00 $28.80

Answers

Answer:

She pays $19.20

Step-by-step explanation:

Given,

The cost price of the shirt = $ 24,

There is a 20% off,

So, the selling price of the shirt = cost price - 20% of cost price

=24-20\%\text{ of }24

=24-(20* 24)/(100)

=24-(480)/(100)

=24-4.8

=\$ 19.2
24*.2=4.8
24-4.8=         $ 19.20
