A=2 b=4 c=1
the answer the the discriminant is 8 which is positive meaning there are 2 real number solutions
Alinara [238K]3 years ago
6 0

Answer:

8

There are two real solutions

Step-by-step explanation:

We have the following quadratic equation

2x^2+4x+1=0

a refers to the coefficient next to x^2

b refers to the coefficient with x

c refers to the number without x

This means that

a=2\\b=4\\c=1

We now can plug these variables into the discriminant formula

b^2-4ac\\\\(4)^2-4(2)(1)\\\\16-8\\\\8

As our answer is positive, we can determine that this quadratic equation has two real solutions.

At the beginning of a snowstorm, Grayson had 10 inches of snow on his lawn. The snow then began to fall at a constant rate of 0.
maxonik [38]

Answer:

  • Grayson had 10 inches of snow in his lawn
  • the snow falls at a constant rate of 0.5 inches per hour
  • no snow was melting
  • the snow has fallen for 3 hours  

Let y be the height of the snow in the lawn

Grayson had 10 inches at the beginning (at t=0) so y= 10

3 hours passed so y= 10 + 3*0.5 = 11.5 inches

Grayson had 11.5 inches after three hours

Assuming that the snow continued to fall for an unkhown time t

y = 0.5*t + 10

we had 10 at the beginning so we add 10 (+10)

the snow is growing by 0.5 inches in the single hour so we multiply by 0.5

t is the time and it can 4, 5, 6 ...... hours

Just like a function :

  • 0.5 is the slope
  • t is the variable
  • 10 is the y-intercept
