Answer:
pift^2(or your third option) is the area of a circle with a radius of 1.
Hi there!
When we have an equation standard form...

...the formula of the discriminant is
D = b^2 - 4ac
When
D > 0 we have two real solutions
D = 0 we have one real solutions
D < 0 we don't have real solutions
1.) Find the value of the discriminant and the the number of real solutions of
x^2-8x+7=0
Plug in the values from the equation into the formula of the discriminant

D > 0 and therefore we have two real solutions.
2.) Find the value of the discriminant and the number of real solutions of
2x^2+4x+2=0
Again, plug in the values from the equation into the formula of the discriminant.

D = 0 and therefore we have one real solution.
~ Hope this helps you.
Answer:
the total cost of the laptop with tax is 958.45
Step-by-step explanation:
Answer - 8
explanation -
6/3 = 2, meaning each “fourth” is 2. the whole team, (4/4) would be 4x2, which is 8
<h2>Volume of Sphere</h2>
1. What is the radius of the stone sphere?
- To know what is the radius divide is by 2.
Therefore, the radius of the stone sphere is 3in
2. What is the volume of the stone sphere?
- Using the formula in finding the Volume of Sphere
to get the answer. Where the volume of the sphere is
multiplied by the cube of the radius.
Therefore, the volume of the stone sphere is 113.04in³
3. Another stone sphere for the garden has a diameter of 10 inches. What is the volume of the stone sphere? Use 3.14 for <em>π</em>, and round to the nearest hundredth.
- Using the formula in finding the Volume of Sphere
to get the answer. Where the volume of the sphere is
multiplied by the cube of the radius.
<h3>Explanation</h3>
Therefore, the volume of the stone sphere is 523.33in³
