Answer: a) 3 sqdroot (2) B) 12

Explanation: Explanation is in the picture. There is an easier way to solve this which is to factor the 6. The factors would be 3 and 2. Because there are two pairs of 3s (sqdroot 3 x sqdroot 3x2), 3 will go out of the sqdroot while 2 stays in it.

For the equation ae^ct=d, solve for the variable t in terms of a,c, and d. Express your answer in terms of the natural logarithm

saveliy_v [14]

We have been given an equation $ae^{ct}=d$ . We are asked to solve the equation for t.

First of all, we will divide both sides of equation by a.

$\frac{ae^{ct}}{a}=\frac{d}{a}$

$e^{ct}=\frac{d}{a}$

Now we will take natural log on both sides.

$\text{ln}(e^{ct})=\text{ln}(\frac{d}{a})$

Using natural log property $\text{ln}(a^b)=b\cdot \text{ln}(a)$ , we will get:

$ct\cdot \text{ln}(e)=\text{ln}(\frac{d}{a})$

We know that $\text{ln}(e)=1$ , so we will get:

$ct\cdot 1=\text{ln}(\frac{d}{a})$

$ct=\text{ln}(\frac{d}{a})$

Now we will divide both sides by c as:

$\frac{ct}{c}=\frac{\text{ln}(\frac{d}{a})}{c}$

$t=\frac{\text{ln}(\frac{d}{a})}{c}$

Therefore, our solution would be $t=\frac{\text{ln}(\frac{d}{a})}{c}$ .

Hi
let me help u with that

you can only change some numbers to mixed fractions
you can change this question

this is how you change 9/8 to a mixed number (fraction)

8+1 = 9
1 1/8 is the answer
1 times 8 = 8
8 + 1 = 9

PLEASE HELP! ASAP! Thanks! In the system -9x-10y=17 and -10x-10y=10. What is the value of 2x?

Arisa [49]

Answer:

2x=14

Step-by-step explanation:

multiply the second equation by -1 and then when you add, the y's cancel out when you add and you are left with 1x=7. so multiply it by 2 and you get 14
