Answer: [tex]\dfrac{1}{16}x^{-5}y^{-2}z^{4}[/tex]
Step-by-step explanation:
Given
Expression is [tex]\left(4xy^3z^{-2}\right)^{-2}\cdot x^{-3}y^4z^0[/tex]
using the Exponent property that is
[tex][(a)^b]^c=a^{b\cdot c}\\a^x\cdot a^y=a^{x+y}[/tex]
Applying the above property
[tex]\Rightarrow \left(4xy^3z^{-2}\right)^{-2}\cdot x^{-3}y^4z^0=4^{-2}x^{-2}y^{-6}z^{4}\cdot x^{-3}y^4z^0\\\\\Rightarrow \left(4xy^3z^{-2}\right)^{-2}\cdot x^{-3}y^4z^0=4^{-2}x^{-2-3}y^{-6+4}z^{4+0}\\\Rightarrow 4^{-2}x^{-5}y^{-2}z^{4}=\dfrac{1}{16}x^{-5}y^{-2}z^{4}[/tex]

Pamela is shopping for bottled water at the supermarket. Which is the best buy?
A 1 2-liter bottle for $0.89
B 3 1-liter bottles for $1.50
C 24 0.5-liter bottles for $5.25
D 36 0.25-liter bottles for $4.75
Explain correctly. No nonsense, please.
Thank you
Answers
First, add up how many full liters are in each answer
a - 2 liters
b - 3 liters (3 + 1 = 3)
c- 12 liters (24 x 0.5 = 12)
d - 9 liters (36 x 0.25 = 9)
So now you know how many liters of water you’re getting for what price which is
a. 2 liters for .89
b. 3 liters for 1.50
c. 12 liters for 5.25
d. 9 liters for 4.75
Now, you must divide the price by how many liters you’re getting to know how much each liter cost by itself.
a- .89 divided by 2 = .45 cents a liter
b- 1.50 divided by 3 = .50 cents a liter
c- 5.25 divided by 12 = about .44 cents a liter
d- 4.75 divided by 9 = -about .52 cents a liter
So by the information, the cheapest and best deal would be answer C because it cost the least for 1 liter (.44 cents)

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is studying the change in the amount of money in two accounts, A and B, over time.
The amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 10,125(1.83)x
Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer. (5 points)
Part B: The table below shows the amount g(r), in dollars, of money in account B after r years:
r (number of years) 1 2 3 4
g(r) (amount in dollars) 9,638 18,794.10 36,648.50 71,464.58
Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer. (5 points)
Answers
Answer:
It looks like your first account increases linearly,
unless you have a typo and meant:
f(x) = 10,125(1.83)^x
the second
exponential and can be written as
g(r) = 9,638(1.95)^r
clearly g(r) has a higher percentage change since 1.95 > 1.83
a more interesting question might have been: When will the amount be the same?
10,125(1.83)^x = 9,638(1.95)^x
10,125(1.83)^x = 9,638(1.95)^x
(1.83)^x = .951901...(1.95)^x
take log of both sides and use log rules
xlog1.83 = log .951901... + log 1.95
x(log 1.83 - log 1.95) = log .951901...
x = .776..
check:
f(.776..) = 10,125(1.83)^.776.. = 1618410
g(.776..) = 9,638(1.95)^.776... = 16184.10

PQ is tangent to the circle and m
Answers
Answer:
x = 78°
Step-by-step explanation:
m<P = 12°
Since PQ is tangent to the circle at point Q, therefore m<Q = 90° (tangent theorem)
x + m<P + m<Q = 180° (sum of triangle theorem)
Substitute
x + 12° + 90° = 180°
x + 102° = 180°
Subtract 102° from each side
x = 180° - 102°
x = 78°

Find the area of the shaded region. Round to the nearest hundredth where

Answers
Answer:
look at the picture i have sent
The area of the shaded region is 192.325 m².
What is area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
We have,
Outer radius = 21/2 = 10.5 m
Inner radius = 10.5 - 3.5 = 7 m
So, Area of shaded region
= π( R² - r²)
= 3.14 (10.5² - 7²)
= 3.14 (110.25 - 49)
= 192.325 m²
