Pls expand this logarithmic equation!
[tex]ln(x^9*y^8)[/tex]
Answer:
ln([tex]x^{9}[/tex] * [tex]y^{8}[/tex])
Step-by-step explanation:
property: ln( A * B ) = ln(A) + ln(B) :)
ln([tex]x^{9}[/tex]) + ln([tex]y^{8}[/tex])
property: ln([tex]A^{x}[/tex]) = xln(A)
9*ln(x) + 8*ln(y) ;)
the next model of a sport car will cost 14.9% more than the current model. The current costs $43,000. how much will the price increase in dollars ? what will be the price of the next model
Answer:
The price of the new model will be $49,407.
Step-by-step explanation:
Percentages
The current model of a sports car costs $43,000. The new model is expected to cost 14.9% more than the current model.
The increase is:
14.9% of $43,000
=14.9/100 * $43,000
=$6,407
The cost of the new model is:
$43,000 + $6,407 = $49,407
The price of the new model will be $49,407.
Simplify (4ab^2)^3
Any help is appreciated
Answer:
[tex]64a^{3} b^{6}[/tex]
Step-by-step explanation:
1) Distribute the exponent outside of the parentheses to the terms inside the parentheses. In this case, multiply the 3 outside the parentheses with the exponent of each of the terms inside:
[tex](4ab^{2} )^3[/tex]
[tex]4^{3}[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]
2) The variables are fine - you can't simplify them further. All you need to do now is multiply the [tex]4^{3}[/tex] out. Remember that it's kind of like asking, "what is 4 × 4 ×4?"
[tex]4[/tex] · [tex]4[/tex] · [tex]4[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]
[tex]16[/tex] · [tex]4[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]
[tex]64a^{3} b^{6}[/tex]
Therefore, [tex]64a^{3} b^{6}[/tex] is the answer.

There are 4 quarts in 1 gallon. A restaurant orders 112 quarts of milk to use 3 points as an ingredient in holiday baking. How many gallons of milk did they order?
Answer:
The restaurant ordered 28 gallons of milk.
Step-by-step explanation:
We have 4 quarts in 1 gallon:
[tex] \frac{1 G}{4 Q} [/tex]
Since the restaurant orders 112 quarts we have:
[tex] \frac{1 G}{4 Q}*112 Q = 28 G [/tex]
Hence, the restaurant ordered 28 gallons of milk.
I hope it helps you!

Answer:
Option A
Step-by-step explanation:
Domain of a function is a set of x-values (input values).
Range of a function is a set of y-values (output values).
Since, input and output values of the function given in the graph vary from negative infinity to positive infinity
Domain of the function given in the graph will be,
(-∞, ∞)
And range of the function is,
(-∞, ∞)
Option (A) will be the correct option.
What is the formula for a quadratic function?

[tex]f(x)=ax^2+bx+c \qquad\text{standard form of a quadratic function}\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a} \qquad\text{formula for finding $x$ such that $f(x)=0$}[/tex]
(6-8)(9-10)-(4+2)(6+3) simplified in steps
Answer:
- 56
Step-by-step explanation:
First solve the parenthesis,
(6 - 8) = 2
(9 - 10) = -1
(4 + 2) = 6
(6 + 3) = 9
The equation now looks like; (2)(-1) - (6)(9).
Now solve the parenthesis again,
(2 x -1) - (6 x 9)
2 x -1 = -2
6 x 9 = 54
Now, complete the last equation,
-2 - 54 = -56
-56 is the answer!
Hope this helps!!!
______________________________
1.) Subtract all the parenthesis:[tex](6-8)=-2[/tex][tex](9-10)=-1[/tex]
- We do this because we have to get rid of the parenthesis.
Equation at the end of Step 1:
[tex]-2(-1)-(4+2)(6+3)[/tex]2.) Add all the parenthesis:[tex](4+2)=6[/tex][tex](6+3)=9[/tex]- We do this because we have to get rid of the parenthesis.
Equation at the end of Step 2:
[tex]-2(-1)-6[/tex] × [tex]9[/tex]3.) Now Multiply each side:[tex]-2(-1)=2[/tex][tex]6[/tex] × [tex]9=54[/tex]- We do this to get 1 number on each side left over, and the only way to do so is multiply the remaining numbers.
- Also, the reason we got 2 instead of -2 is because when multiplying 2 negatives by each other the quotient then turns out to be positive.
Equation at the end of Step 3:
[tex]2-54[/tex]4.) Subtract 54 from 2:[tex]2-54=-52[/tex]______________________________
Which expression is equivalent to 1/3b - 7?
Answer:
[tex]\dfrac{1}{3}(b-21)[/tex]
Step-by-step explanation:
We need to find an equivalent expression for [tex]\dfrac{1}{3}b-7[/tex]
The denominator of first fraction is 3 and that of other is 1.
[tex]\dfrac{1}{3}b-7\\\\=\dfrac{b-21}{3}[/tex]
or
[tex]=\dfrac{1}{3}(b-21)[/tex]
Hence, the equivalent expression is [tex]\dfrac{1}{3}(b-21)[/tex].
The answer Is 1/3(b-21)

Step-by-step explanation:
The area of a square is always greater than its perimeter. Which of the following side-lengths for a square provides a counterexample that disproves the statement above?A. 2TT.B. 4.C. 7.5.D. 10.E. 125.
Answer:
a. 2
Step-by-step explanation:
Area of a square is calculated as:
[tex]Area = Length * Length[/tex]
And the perimeter is
[tex]Perimeter = 4 * Length[/tex]
For (a):
[tex]Length = 2[/tex]
[tex]Area = 2 * 2 = 4[/tex]
[tex]Perimeter = 4 * 2 = 8[/tex]
For(b):
[tex]Length = 4[/tex]
[tex]Area = 4 * 4 = 16[/tex]
[tex]Perimeter = 4 * 4 = 16[/tex]
For (c):
[tex]Length=7.5[/tex]
[tex]Area = 7.5 * 7.5-56.25[/tex]
[tex]Perimeter = 4 * 7.5 = 30,[/tex]
For (d):
[tex]Length = 10[/tex]
[tex]Area = 10 * 10 = 100[/tex]
[tex]Perimeter = 4 * 10 = 40[/tex]
For (e):
[tex]Length = 125[/tex]
[tex]Area = 125 * 125 =15625[/tex]
[tex]Perimeter = 4 * 125 = 500[/tex]
From (a) to (e), only side length 2 has a higher perimeter.
Hence, it disproves the statement

fill in the three blanks using three of those answers please!!
Answer:
m + (m + 15) + (m + 2)
Step-by-step explanation:
Even thought we don't know the value of m, we can use expressions to represent it.
Hope this helps.
The required expression is m + (m + 15) + (m + 2) which represents the total number of miles Marla, Lawrence, and Jerry drove in all.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.
Let's represent Marla drove "m" miles.
Since Lawrence drove 15 more miles than Marla.
So, this means the expression m + 15
Then Jerry drove 2 more miles than Marla.
So, this means the expression m + 2
Now, the total number of miles = m + (m + 15) + (m + 2)
This expression represents the total number of miles Marla, Lawrence, and Jerry drove in all.

What is the answer to -12=x+8divided by -3
[tex] - 12 = x + \frac{8}{ - 3} [/tex]
[tex] - 12 - ( \frac{8}{ - 3} ) = x[/tex]
[tex] - 12 - \frac{8}{3} = x[/tex]
[tex] \frac{ - 36}{3} - \frac{8}{3} = x[/tex]
[tex] \frac{ - 36 - 8}{3} = x[/tex]
[tex] \frac{44}{3} = x[/tex]
