2x=8(x^2)
What is the solution of this maths equation?
Answers
Answer:
x=0,x=1/4
Step-by-step explanation:
2x=8(x^2)
Subtract 8(x^2) from both sides
2x-8x^2=8x^2-8x^2
Simplify
2x-8x^2=0
Factor 2x-8x^2;
2x-8x^2
=-8xx+2x
Rewrite 8 as 2*4
=-2*4xx+2x
Factor out common term -2x
=-2x(4x-1)
-2x(4x-1)=0
x=0 or 4x-1=0
Solve 4x-1=0;x=1/4
4x-1=0
Add 1 to both sides
4x-1+1=0+1
Simplify
4x=1
Divide both sides by 4
4x/4=1/4
Simplify
x=1/4
The solutions to the quadratic equation are;
x=0,x=1/4

Step-by-step explanation:
A 256- gallon barrel of radioactive Urikium is spilled at a factory. The entire area is evacuated. Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is to toxic for any clean-up efforts, so residents will just have to wait for the Urikium to evaporate. Fortunately, Urikium has a half-life of only three hours. That means that half of the Urikium will evaporate every three hours
Answers
Answer:
21 hours
Step-by-step explanation:
Since 2^8 = 256, that means it will take 7 half-lives to become two gallons
7 half-lives * 3 hours = 21 hours
256, 128, 64, 32, 16, 8, 4, 2
Answer:
Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is too toxic for any clean-up efforts. She residents will
Step-by-step explanation:
To solve half-life problems, you use the equations:
f(t) = T0 (1/2)^(t/t1/2). where T0 is the initial mass and T1/2 is the half-life.
So we get f(20)= 5 = T0•(1/2) ^ 20/11
T0 = 17.63 mg
For the second part of the question, we plug 0.5 mg into the equation:
0.5 = 17.63 • (1/2)^ t/11
t = 56.5 days
3. Suppose the radius of the larger circle is r. What is its diameter?
d2 =
R2
Answers
Answer:
2r
Step-by-step explanation:
You suppose that the radius of a larger circle = r
so diameter = r*2 = 2r
aint really sure tho
Answer:
2R
Step-by-step explanation:
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
