M1= 5 , M2=1

Explanation:

12-3m-4-5/m=0
8-3m-5/m=0
(8-3m-5/m=0) * m
8m-3m^2-5=0
8m-3m^2=5
m(8-3m)=5
m1=5
m2=> (8-3m)=5
3m=3
m2= 1

Answer:

$m=1\\m=\frac{5}{3}$

Step-by-step explanation:

$12 - 3m = 4 + \frac{5}{m}$

$8=\frac{5}{m} +3m$

Multiply the whole thing by m

$8m = 5 +3m^{2}$

$3m^{2} -8m + 5 = 0$

$(3m^{2} -3m) + (-5m +5)$

$3m(m-1)-5(m-1)=0$

$3m-5=1\\m-1=0$

$m=1\\m=\frac{5}{3}$

a circular oil slick is expanding at a rate of 2m^2/h. Find the rate at which it's diameter is expanding when it's radius is 1.5

aleksandrvk [35]

Answer: $\frac{4\pi}{3} \text{ meter per hour}$

Step-by-step explanation:

The circular oil slick is expanding at a rate of $2 m^2/h$

Let A be the area of the circular oil slick,

So, the changes in A with respect to time (t),

$\frac{dA}{dt} = 2$

$\frac{d(\pi r^2)}{dt} = 2$

$2\pi r\frac{dr}{dt} = 2$

$\frac{dr}{dt} = \frac{1}{\pi r}$

Also, the change in diameter with respect to time(t),

$\frac{d}{dt} (2 r) = 2 \frac{dr}{dt}$

$\frac{d}{dt} (2 r) = 2 \times \frac{1}{\pi r}$

$\frac{d}{dt} (2 r) = \frac{2}{\pi r}$

For r = 1.5 m,

$\frac{d}{dt} ( 2 r)]_{r=1.5} = \frac{2}{\pi \times 1.5}=\frac{20}{\pi \times 15}=\frac{4\pi }{3}\text{ meter per hour}$

Hi are you able to solve it by using a step called exponential equations?

andriy [413]

Given the equation:

$6^{2-3x}=6^{-2x-2}$

since both bases are 6, we can equate both exponents to get the following equation:

$2-3x=-2x-2$

solving for x, we get:

$\begin{gathered} 2-3x=-2x-2 \\ \Rightarrow-3x+2x=-2-2=-4 \\ \Rightarrow-x=-4 \\ \Rightarrow x=4 \end{gathered}$

therefore, the solution of the equation is x = 4
