How many complex roots does the equation below have? X^6+x^3+1=0
gladu [14]
If you find the discriminant it will tell you the number and types of roots. The discriminant is the value b^2 -4ac.
a = 1
b = 1
c = 1
1^2 - 4*1*1
1-4 = -3
Since this is a negative number there will be 2 complex roots.

The bull’s-eye on a target has diameter 2 in. What is the area of the bull’s-eye to the nearest tenth? Use 3.14 for π
777dan777 [17]

Answer:

20.3cm^2

Step-by-step explanation:

Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2

Díameter is 2 inches = 5. 08cm

But radius = diameter /2

Radius = 5.08cm /2

Radius = 2.54cm

Hence Area of bulleyse = 3.14 x (2.54) ^2

= 3.14 x 6. 451 cm^2

= 20.256 cm^2

=20.3cm^2 (to nearest tenth)

a store is having a sale on walnuts and chocolate chips. for 3 pounds of walnuts and 5 pounds of chocolate chips, the total cost
Step2247 [10]

Answer:

  • Walnuts - $1.25, chocolate chips - $3.25

Step-by-step explanation:

Let walnuts = x, chocolate chips = y

<u>Set a system and solve:</u>

  • 3x + 5y = 20
  • 6x + 2y = 14

<u>Double the first equation and subtract the second one from it:</u>

  • 6x + 10y - 6x - 2y = 40 - 14
  • 8y = 26
  • y = 26/8
  • y = 3.25

<u>Find the value of x:</u>

  • 6x + 3.25*2 = 14
  • 6x = 14 - 6.5
  • 6x = 7.5
  • x = 7.5/6
  • x = 1.25
