Answer:

z=44/3

Step-by-step

Subtract the numbers 52-12=40

3z-4=40

Add 4 to both sides

3z-4+4=40+4

SImplify

3z=44

Divide both sides by 3

3z/3 = 44/3

z=44/3 or decimal form= 14.66

Expanding Logarithmic Expressions In Exercise, use the properties of logarithms to rewrite the expression as a sum, difference,

aev [14]

Answer:

The simplified expression is:

$\ln{x} + \frac{\ln{(x-1)}}{2}$

Step-by-step explanation:

We have those following logarithmic properties:

$\ln{\frac{a}{b}} = \ln{a} - \ln{b}$

$\ln{a*b} = \ln{a} + \ln{b}$

$\ln{a^{n}} = n\ln{a}$

In this problem, we have that:

$\ln{x^{2}(x-1)}^{1/2}$

Applying these properties

$\frac{1}{2}*(\ln{x^{2} + \ln{(x-1)})$

$\ln{x} + \frac{\ln{(x-1)}}{2}$

Calculate the distance between points (-8,-2) and (4,3)

Kamila [148]

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\\\\ \mathsf{d=\sqrt{(4-(-8))^2+(3-(-2))^2}}\\\\ \mathsf{d=\sqrt{(4+8)^2+(3+2)^2}}\\\\ \mathsf{d=\sqrt{(12)^2+(5)^2}}\\\\ \mathsf{d=\sqrt{144+25}}\\\\ \mathsf{d=\sqrt{169}}\\\\ \underline{\mathsf{d=13}}$

The answer is 13 uc.

Use simple interest to find the ending balance

Elena-2011 [213]

Answer: 7788.50

Solving steps:
P = 7400, R = 10.5%, T = 6

F = P + P rt
P = 7400
R = 10.5%
T = 6

F = 7400 + 7400rt

7400 x (12 + 6 x 0.105/12

7400 x (12 + 0.63)/12

7400 x 12.63/12

93462/12

15577/12

15577/2 0.01
7788.50

Read the problem and decide whether it has too much or too little

Likurg_2 [28]

Answer:

The correct option is B) Too much

Step-by-step explanation:

Consider the provided information.

We need to find the How many people attended the Boxerville Carnival on the weekend?

Workweek is from Monday to Friday and the weekend is Saturday and Sunday,

It may be different for different countries.

In order to find the number of people attended the Boxerville Carnival on the weekend we need to add the number of people attended the carnival on Saturday and Sunday.

On Saturday at the Boxerville Camival 800 people attended. On Sunday, 650

Therefore total number of people attended the carnival are:

800+650=1450

Hence, 1450 people attended the carnival.

In the provided problem we have given too much information.

Hence, the correct option is B) Too much
