Write each expression as an equivalent expression with a single logarithm. Assume xx, yy, and zz are positive real

Alekssandra [29.7K]

Answer:

$\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$

Step-by-step explanation:

Given:

1/2(ln(xx + yy) − ln(zz))

Now,

From the properties of log function,

1) n × ln(x) = ln(xⁿ)

and,

2) ln(A) - ln(B) = $\ln\frac{A}{B}$

applying the properties in the given equation

we get the above equation as:

$\frac{1}{2}(\ln\frac{xx + yy}{zz})$

( using the property 2 we get (ln(xx + yy) − ln(zz) = $\ln\frac{xx + yy}{zz}$

or

⇒ $\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$ ( using the property 1 i.e n × ln(x) = ln(xⁿ) )

expression as an equivalent expression with a single logarithm is $\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$

PLEASE HELP ASAP!!!!!

Answer:

B = (3, 3)

Step-by-step explanation:

Since the line segment is fifteen units long, from the looks of it, chopping ⅓ of A's side, led to the ordered pair of (3, 3).

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.

when you subtract a negative integer from another, will your answer be greater than or less than the integer you started with? e

BlackZzzverrR [31]

It depends if the negative number is bigger than the positive number your answer will be a negative number/answer for example -9 - 4 your answer would be -5 since the negative number is bigger it will be the other way around for a positive number if the positive number is bigger than the negative number your answer will be positive for example 5 - -2 = 3 or positive 3.

PLEASE HELP !!!!!!! Jordan got a new money bank for his birthday with $20 inside. He puts part of his weekly allowance in his ba

kupik [55]

Answer:

Slope of the function is $=3.75$ ,Y-intercept $=20$ .

The function is $y=3.75(x)+20$ with initial value $=20$ ,Jordan puts $\$3.75$ each week andthe amount saved by Jordan after $52$ week $=215\$$ .

Step-by-step explanation:

To understand the slope and y-intercept lets assign $x$ as number of weeks and $y$ as the money saved by Jordan.

Jordan is already having a sum of $\$20$ inside the money bank so in $0$ week the amount is $\$20$ can be written as $(x,y) =(0,20)$ in coordinate form.

SImilarly

We have $(x,y) =(0,20)$ and $(x_1,y_1) =(25,113.75)$

Part A:

The function is $y=m(x)+b$

From point-slope form,we have slope (m)

and $m=\frac{y_1-y}{x_1-x}$ ,plugging the values of the points.

$m=\frac{113.75-20}{25-0}=3.75$

Y-intercept of this function is the constant term or the money of $\$20$ that is already inside the money bank.

We can also calculate y-intercept by arranging the function as $b=y-m(x)$ choosing any $(x_1,y_1) = (25,113.75)$ coordinate and here $b$ is the y-intercept.
