Answer:

C

Step-by-step explanation:

A = $\pi$ r²

so we do

5² = 25 * $\pi$

25 * $\pi$

= 78.5 square units

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

What is -3.75 in the simplest form

NARA [144]

There is no simplest form for a decimal. You can only simplify equations and fractions, not decimals. For example, could you simplify 1? I don't think you could. Well, it's the same concept for -3.75.
Hope that answered your question.

The American Water Works Association reports that the per capita water use in a single-family home is 74 gallons per day. Legacy

Lunna [17]

Answer:

Reject H0 since test statistic <-2.492

Step-by-step explanation:

Given that the American Water Works Association reports that the per capita water use in a single-family home is 74 gallons per day.

n = 25

x bar = 69

s= 8.3

std error = s/sqrt n = $\frac{8.3}{5} \\=1.66$

H0: $\bar x = 74$

Ha: $\bar x$

(Left tailed test at 5% significance level)

a) Reject H0 if t $\leq$ -2.492

b) Test statistic = mean difference/std error

= $\frac{69-74}{1.66} \\=-3.012\\$

=-3.01

df =24

c) Reject H0
