Answers
Answer:
29 years
Step-by-step explanation:
Given the function [tex]f(x)= 200(0.5)^{\frac{x}{50} }[/tex], where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.Another way of doing this is to change the function to [tex]f(x)=200(0.5^{\frac{1}{50} })^{x}[/tex] which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate. I'll use the 1st function because the question doesn't ask for the rate[tex]f(x)= 200(0.5)^\frac{140}{50}}[/tex]

Find a28 of the arithmetic sequence given a1=1 and d=-9
Answers
The a28th term of a arithmetic sequence is -242.
According to the statement
We have given that :
a1 = 1 and d = -9. And by use of it we have to find the value of the a28th term in the arithmetic sequence.
So, arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
And the formula is
an = a1 +(n-1)d
here put the values in it
an = a28 , n = 28, d =-9, a1 =1
then
an = a1 +(n-1)d
a28 = 1 +(28-1)(-9)
a28 = 1 +(27)(-9)
a28 = 1 -243
a28 = -242.

Dina's mother is four times older than Dina. Dina is 35 years younger than her father. Dina's father was 5 years older than Dina's mother when Dina was born. How old is Dina now?
Answers
Answer:
10 years old
Step-by-step explanation:
Let m = mother's age
Let f = father's age
Let d = Dina's age
m = 4d d = f-35 f = m+5
Substitute the middle equation in to the first equation
m = 4(f - 35) Use the distributive property
m = 4f - 140 subtract 4f from both sides
*m -4f = -140
In equation 3 above, subtract m from both sides to get
f = m+5
f - m = 5 rearrange so that the m term is first
*-m + f = 5
Now add the equations together that have *
m -4f = -140
-m + f = 5
-3f = -135 Divide both sides by -3
f = 45 This is the father's age. To find Dina's age, plug 45 into the second equation above:
d = f -35
d = 45 -35
d = 10.
To find the mom's age, use the third equation:
f = m+5
45 = m + 5
40 = m
You can check this by plugging the answers you found and you can see that all three equations are solved.
m = 4d d = f - 35 f = m + 5
40 = 4(10) 10 = 45 - 35 45 = 40 + 5
40 = 40 10 = 10 45 = 45

What is meant by stretching vertically and flipping?A function change called a stretch or compression makes a graph bigger or narrower without moving it horizontally or vertically.
Vertical stretching: A function's graph is stretched or compressed vertically in proportion to the graph of the original function when we multiply it by a positive constant. We obtain a vertical stretch if the constant is bigger than 1, and a vertical compression if the constant is between 0 and 1.flipped over the x-axis: In order to reflect over the X axis, one must negate the value of each point's y-coordinate while maintaining its x-value.

A square garden has sides of length 10 ft. If topsoil costs $5 / cubic foot, how much will it cost to put a 0. 5 ft layer of topsoil on the entire garden?
Answers
Cost to put a 0. 5 ft layer of topsoil on the entire garden is $1000.
The quantity of square units required to completely fill a square is known as the area of a square. The region that lies inside the confines of a flat item or a two-dimensional figure is generally referred to as the area. Measurements are made in square units, with square meters serving as the reference unit
Area of a Square = Side × Side.
Therefore, the area of square = Side square units.
Side of a square garden= 10 ft.
Area of a square garden= Side × Side= 10 × 10 =100 square ft.
Cost of the whole garden = 100×$5 =$500
Cost to put a 0. 5 ft layer of topsoil on the entire garden =$500/0.5

The cost need to put a 0. 5 ft layer of topsoil on the entire garden is $1000
According to the given statement
we have given that the
side length of the square garden is 10ft.
topsoil cost per foot is $5
And we have to find the cost which required to put a 0. 5 ft layer of topsoil on the entire garden.
So,
The side length of the square garden is 10ft.
Now, the volume of the cube is (a)^2
And
Total volume of cube = 10*10
Total volume of cube = 100 per square foot.
Now, we find the cost required for a topsoil.
Cost required to put a topsoil of 1 foot in the total volume of cube = volume*cost
So,
Cost required to put a topsoil of 1 foot in the total volume of cube = 1000*5
Cost required to put a topsoil of 1 foot in the total volume of cube = $5000
if we put a topsoil of 0.5 feet then
The cost required = $5000/0.5
The cost required = $1000.

If Dwayne drinks 48 bottles of water in 12 days, how many bottles of water will he drink in 4 days?
Answers
Dwayne will drink 12 bottles of water in 4 days.
To find out how many bottles of water Dwayne will drink in 4 days, we can set up a proportion based on the information given:
Let x be the number of bottles of water he will drink in 4 days.
The number of bottles of water consumed per day remains constant, so we can set up the following proportion:
48 bottles / 12 days = x bottles / 4 days
Now, solve for x:
48 / 12 = x / 4
4x = 48
x = 48 / 4

Answers
Step-by-step explanation:
Let S be the set of all the stores in the sample, A be the set of stores dealing with Asian companies and E but the set of stores dealing with European companies
i. The set of stores that deal with European or Asian companies is A ∪ E. The inclusion-exclusion principle states that |A ∪ E| = |A| + |E| - |A ∩ E| = 266 + 308 - 103 = 471. So P(A ∪ E) = 471/500 = 0.942
ii. E' = S - E. |S-E| = 500 - 308 = 192. So P(E') = 192/500 = 0.384
iii. |A - E| = |A| - |A ∩ E| = 266 - 103 = 163. So P(A - E) = 163/500 = 0.326
iv. Stores that do not deal with only one type of company, must deal with both Asian and European companies. We are given that |A ∩ E| = 103. So P(A ∩ E) = 103/500 = 0.206
