ohaa [14]

Answer:

He has 42 more minutes to drive and 44 miles to cover to arrive at the university

Step-by-step explanation:

If he drives 63 miles in 1 hr

he would drive 107 miles in

107/ 63 = 1.7 hours

to convert 0.7 to time, multiply by 60 = 42 minutes

his total travel time is 1 hr 42 minutes

He has 42 more minutes to drive and 44 miles to drive

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

The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the near

svet-max [94.6K]

Explanation:

Formula to calculate pH of a chemical or solution is as follows.

pH = $-log [H^{+}]$

Therefore, calculate the pH of given chemicals as follows.

1). Oven cleaner

pH = $-log [H^{+}]$

= $-log [10^{-13}]$

= 13

2). Water

pH = $-log [H^{+}]$

= $-log [7 \times 10^{-7}]$

= 6.15

3). Blood

pH = $-log [H^{+}]$

= $-log [4 \times 10^{-8}]$

= 7.40

4). Vinegar

pH = $-log [H^{+}]$

= $-log [63 \times 10^{-4}]$

= 2.20
