Answer: [tex]\ln\left(\frac{a^2}{y^4}\right)[/tex]
============================================================
Explanation:
I'll be using these log rules
Blog(A) = log(A^B)log(A) - log(B) = log(A/B)which I'll refer to as "rule 1" and "rule 2" respectively. There are other log rules, but we only need to use these two for this particular question.
Here's how the steps could be laid out:
[tex]2\ln\left(a\right)-4\ln\left(y\right)\\\\\ln\left(a^2\right)-\ln\left(y^4\right) \ \text{ ... use rule 1}\\\\\ln\left(\frac{a^2}{y^4}\right) \ \text{ ... use rule 2}\\\\[/tex]
Side note: The first letter of "ln" is a lowercase L, and not an uppercase i

Can any one please help me under this? I need to know which option indicates that 3 goes after 5and between 7,12and 5 then how that goes before 12 and between7 and 3. I’ve been reading this forever and I don’t understand her wording. Help please! Ayuda porfavor!
"3 va después de 5 y entre 7 y 12" = "3 goes after 5, and between 7 and 12"
This eliminates A and D (3 is not between 7 and 12 in either choice).
"5 va antes de 12 y entre 7 y 3" = "5 goes after 12, and between 7 and 3"
This eliminates C (5 is not between 7 and 3).
So the correct sequence is B.

-4x - 2y =-18 x + 3y = 8
Answer:
Elimination:
-4x - 2y = -18 -4x - 2y = -18
x + 3y = 8 | ×4 ------> 4x + 12y = 32 +
10y = 14
y = 1,4
x + 3y = 8
x + 3(1,4) = 8
x + 4,2 = 8

Then the number of the seconds is taken by the fourth team will be
Let x be the number of the second taken by the fourth team.
Then we have
x + 46.685 + 48.869 + 49.33 = 190.729
x + 144.884 = 190.729

The price of petrol goes up 10%, by how much percent must a motorist reduce the consumption of petrol so that the expenditure on it remains unchanged ?
[tex]\large{\sf \boxed{ \sf 9.09 \ \%}}[/tex]
Explanation:
Let the price be p,
When the price is increased by 10%,
Increased price = (100% + 10%) × p = 1.1p
So reduction percentage:
[tex]\rightarrow \sf \dfrac{1.1p - p}{1.1p} \ x \ 100[/tex]
[tex]\rightarrow \sf \dfrac{0.1p}{1.1p} \ x \ 100[/tex]
[tex]\rightarrow \sf 9.090909091 \% \quad \approx \quad 9.09 \% \quad (rounded \ to \ nearest \ hundredth)[/tex]

Answer:
40, 42 and 44Step-by-step explanation:
An Integer is even, if it's divisible by two. it's also a multiple of two.let first integer= Y note : Y is an even number.
second integer= (Y+2)
third integer = (Y+4)
from the question,
Y+Y+2+Y+4= 126
3Y+6 = 126
3Y = 126-6
3Y = 120
dividingbothsides by (3)
3Y/3 = 120/3
Y= 40
therefore, the even integers are:
40
(Y+2)= 40+2= 42
(Y+4) =40+4= 44

n
m∥n, find the value of x and y.
If m is parallel to n then value of x and y is X = 41° and Y = 41°.
What are Angles?An angle is formed when two straight lines or rays meet at a common endpoint.
Given that line m and n are parallel lines.
Parallel lines are those straight lines that are always the same distance apart from each other.
As y is vertically opposite to the angle 41° . So the value of y is also 41° and angle x is equal to angle y because they are alternate angles. So the value of y is also 41°.
Therefore X = 41° and Y = 41°.

A storage tank is in the shape of a cylinder with a hemisphere on the top. The highest point on the inside of the storage tank is 13 meters above the floor of the storage tank, and the diameter inside the cylinder is 8 meters. Determine and state, to the nearest cubic meter, the total volume inside the storage tank.
The volume of the tank of water is 653.12 cubic meters.
How to get the volume?
For a cylinder of height H and diameter D, the total volume is given by:
[tex]V = 3.14*(D/2)^2*H[/tex]
In this case, we know that:
D = 8m
H = 13m
Replacing that in the above equation:
[tex]V = 3.14*(8m/2)^2*13m = 653.12 m^3[/tex]
So the volume of the tank of water is 653.12 cubic meters.

-----------------------------------------------------------------------------------------
Parent function: [tex]f(x)=|x|[/tex]
(with vertex at the origin)
From inspection of the graph, the vertex of the transformed function is at (4, 7). Therefore, there has been a translation of:
4 units right7 units up[tex]\implies f(x-4)+7=|x-4|+7[/tex]
From inspection of the graph, we can see that it has been stretched parallel to the y-axis:
[tex]\implies a\:f(x-4)+7=a|x-4|+7[/tex]
The line goes through point (0, 9)
Substituting this point into the above equation to find [tex]a[/tex]:
[tex]\implies a|0-4|+7=9[/tex]
[tex]\implies 4a=2[/tex]
[tex]\implies a= \dfrac{1}{2}[/tex]

Answer:
None of the choices are correct
Stefofp-by-step explanation:
Simplify the following:
(-6 x^3 y^4 + 9 x^8 y^2)/(3 x y)
Factor 3 x^3 y^2 out of -6 x^3 y^4 + 9 x^8 y^2:
(3 x^3 y^2 (-2 y^2 + 3 x^5))/(3 x y)
(3 x^3 y^2 (-2 y^2 + 3 x^5))/(3 x y) = 3/3×(x^3 y^2 (-2 y^2 + 3 x^5))/(x y) = (x^3 y^2 (-2 y^2 + 3 x^5))/(x y):
(x^3 y^2 (-2 y^2 + 3 x^5))/(x y)
Combine powers. (x^3 y^2 (-2 y^2 + 3 x^5))/(x y) = x^(3 - 1) y^(2 - 1) (-2 y^2 + 3 x^5):
x^(3 - 1) y^(2 - 1) (-2 y^2 + 3 x^5)

Two similar squares have matching sides whose lengths are in the ratio 7:5 Find the ratio of their areas.
Answer:
49:25
Step-by-step explanation:
When you have a side length ratio given, the area ratio will be the side length ratio squared.
This can be thought of quite easily, say you have 1 square with a side length of 7 and another square with a sidelength 5.
Of course the squares have a side length ratio of 7:5
The area of the first square is 7*7 = 49
The area of the second square is 5*5 = 25
Then clearly the ratio of the areas is 49:25
