The bottom surface of the glass container will be covered a quarter of the way on March 8th.

Step-by-step explanation:

The bacteria covering the bottom surface of the glass container doubles every day. If the surface is completely covered on March 10th, then one day earlier, on March 9th, half of the surface is covered.

Similarly, if half of the surface is covered on March 9th, then one day earlier, on March 8th, a quarter of the surface is covered.

Therefore, the bottom surface of the glass container will be covered a quarter of the way on March 8th.

The bottom surface of the glass container will be covered a quarter of the way on March 8th.

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = b^x is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

The microorganism protecting the lowest floor of the glass box doubles each day. If the floor is absolutely protected on March 10th, then in the future earlier, on March 9th, 1/2 of the floor is protected.

Similarly, if 1/2 of the floor is protected on March 9th, then in the future earlier, on March 8th, 1 / 4 of the floor is protected. Therefore, the lowest floor of the glass box can be protected 1 / 4 of the manner on March 8th.

Therefore, the bottom surface of the glass container will be covered a quarter of the way on March 8th.

Answer:

Step-by-step explanation:

3×2k=????

3×5=??

6×k=??

6×4=??

then put all those together in a 2 step equation and then add 9 to the answer

The equation 3(2k-5)=6(k-4)+9 has infinitely many solutions.

Two or more expressions with an Equal sign is called as Equation.

3(2k-5)=6(k-4)+9

In the given equation k is the variable

Now apply distributive property to the RHS and LHS wherever it is required

6k-15=6k-24+9

6k-15=6k-15

Shift all terms to one side

6k-15-6k+15=0

0=0

Hence the equation 3(2k-5)=6(k-4)+9 has infinitely many solutions.

Answer: K = -6

Step-by-step explanation:

When you add or subtract on one side, you have to do the same to the other side. You also have to get all the numbers with vairables on one side, and the ones without on the other side.

When you have a positive number, if you want to bring it to the other side, you have to subtract it. For example, if you want to bring 8k from the left side onto the right side, you have to subtract 8k from a number on the right side.

For this equation, lets bring all the numbers with vairables onto one side, and the ones without vairables on the other side. The ones with vairables will be on the left, and the numbers without will be on the right.

To bring 10k from the right side to the left, we have to subtract 10k from 8k. 8k - 10k = -2k.

Now we have to bring the -6 from the left side onto the right side. Since -6 is a negative number, we have to make it into a positive number to swap it to the other side. So it because 6. We add 6 to -6, and 6 to 6. The leaves the left side to be -2k, and the right side to be 12.

Now we have to divide. 12 ÷ -2 = -6. Therefore, k = -6. I hope this helps, and good luck on whatever you're doing :D

Answer:

Step-by-step explanation:

4,800 mcg × 0.5^t = 300 mcg

0.5^t = 1/16 = (1/2)⁴

t = 4

Answer:

[tex]4,800\left(\frac{1}{2}\right)^{t} \, = \, 300; \ 3 \ \text{hours}[/tex]

Step-by-step explanation:

Every hour, the research assistant is removing half the mass from the original 4,800 micrograms of the bacteria culture. So, the mass remaining after t hours can be represented by an exponential expression, a(b)t, where a is the initial mass of the bacteria culture and b is the base of the exponent that represents the decay factor. Since half of the mass of bacteria is being removed every hour, half of the mass remains. So, b = [tex]\frac{1}{2}[/tex]. The exponential expression for this situation is [tex]4,800\left(\frac{1}{2}\right)^{t}[/tex].

The research assistant will stop removing half the mass from the original bacteria culture after the original bacteria culture has a mass of 300 micrograms. Hence, set the expression for the mass remaining after t hours equal to 300.

[tex]4,800\left(\frac{1}{2}\right)^{t} \, = \, 300[/tex]

In order to solve this equation for t, the base needs to be isolated. Divide both sides of the inequality by 4,800.

[tex]\begin{array}{rclC40C40} 4,800\left(\frac{1}{2}\right)^{t} &=& 300\\ \left(\frac{1}{2}\right)^{t} &=& \frac{1}{16} \end{array}[/tex]

Next, rewrite the base of [tex]\frac{1}{16}[/tex] as a power of [tex]\frac{1}{2}[/tex]. Then, set the exponents equal to each other to solve for t.

[tex]\begin{array}{rclC40C40C30} \left(\frac{1}{2}\right)^{t} &=& \frac{1}{16} \\ \left(\frac{1}{2}\right)^{t} &=& \left(\frac{1}{2}\right)^{4} \\ t &=& 4 \end{array}[/tex]

So, after 4 hours the research assistant will stop removing half the mass of the bacteria culture.

Answer:

722.57cm²

Step-by-step explanation:

Below, we have listed six basic equations that can be used to derive the explicit formulas of radius of a cylinder:

Volume of a cylinder: V = π * r² * h ,

Base surface area of a cylinder: A_b = 2 * π * r² ,

Lateral surface area of a cylinder: A_l = 2 * π * r * h ,

Total surface area of a cylinder: A = A_b + A_l ,

Surface Area of Cylinders. To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.
