Step-by-step explanation:

$log \frac{4x^2}{3yz}=log {4x^2}-log {3yz}\\=log 4+log x^2-(log 3+log y+log z)\\=log 4+2 log x-log 3-log y- log z$

Find the equation of the sphere centered at (2,−9,1) with radius 2. 4 = (x-2)+(y+9)+(z-1). Give an equation which describes the

Answer:

See explanation

Step-by-step explanation:

The equation of the shpere canterd at point $(a,b,c)$ with radius $R$ is

$(x-a)^2+(y-b)^2+(z-c)^2=R^2$

The center of the sphere is (2,-9,1), the radius is 2, then the equation is

$(x-2)^2+(y+9)^2+(z-1)^2=2^2\\ \\(x-2)^2+(y+9)^2+(z-1)^2=4$

Now, find the intersection of this sphere with the plane z=2. Substitute 2 instead of z into the sphere equation:

$(x-2)^2 +(y+9)^2+(2-1)^2=4\\ \\(x-2)^2+(y+9)^2+1=4\\ \\(x-2)^2+(y+9)^2=3$

This is the equation of the circle lying in the plane z=2 with center at (2,-9,2) and radius $\sqrt{3}.$

A group of scientists studied the effect of a chemical on various strains of bacteria. Strain A started with 6000 cells and decr

forsale [732]

After 3 hours each strain will have been depleted completely to 0 cells. Given the numbers 6000 and 2000, you will find that a decrease of 33.33333% for strain A and a 50% decrease for strain B will not intercept on the same hour. Strain B will have been depleted for an hour at the time that strain A is gone.
