Based on the given problem of -7x⁴ = 36, the solution to the equation is x = -1.5.
<h3>What is the solution to this problem?</h3>
The equation to find x is given as:
-7x⁴ = 36
Solving it gives:
-7x⁴ = 36
x⁴ = 36/-7
x⁴ = -36/7
x = ⁴√(-36/7)
x = -1.5
In conclusion, x is -1.5.

Answer:
y = 3(x+1)^2 - 4
Step-by-step explanation:The general form of the equation of a quadratic function whose vertex is (h,k) and whose leading coefficient is a is:
y - k = a(x-h)^2, or
y = a(x-h)^2 - k
Substituting the coefficients of the vertex (-1, -4), we get:
y = a(x + 1)^2 - 4
Substituting the coordinates of the given point, (1,8), we get:
8 = a(1+1)^2 - 4, which simplifies to:
8 = a(2)^2 - 4, or
8 = 4a - 4. Then 4a = 12, and a = 3.
Thus, the desired equation is y = 3(x+1)^2 - 4 (answer j).
Answer:
1/3x
Step-by-step explanation:
Subtract x by x and y by y to find the distance/difference

Step-by-step explanation:
93-12=81
<span>As the age of the U-235 sample is 2.631 billion years, and the half-life of U-235 is 713 million years, the sample has undergone 2.361 X 1,000,000,000 / 713 X 1,000,000 = 3.69 half lives. In each half-life the sample reduces to half its original weight according to the radioactive Half-Life Formula:
ln (Nt /N0) = -kt, where N0 = mass of the original weight of radioactive material, Nt = mass of radioactive material at time t, k = decay constant and t = time interval . We have to put Nt/N0 = 1/2 for time interval = half-life.</span>
