Question 3 V (t) 30(1.05), where t is the time, in years, since opening the account Connie deposits $30 into an account. The value of the account, in dollars, can be modeled as To the nearest cent, what is the average rate of change in the value of the account for the first 3 years? A $0.63/year B $1.58/year С $3.15/year thing D $4.73/year
Answer:
b
Step-by-step explanation:
The average rate of change in the value of the account for the first 3 years is, $3.15/year. So Option C is correct.
What is the rate?Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.
So formula for the rate is,
m = change in one quantity/change in another quantity = Δy/Δx
The average rate of change in the value of the account for the first 3 years can be calculated as follows:
Let t = 0 be the time when the account is opened,
and t = 3 be the end of the third year.
The value of the account at t = 0 is V(0) = 30,
and the value of the account at t = 3 is
V(3) = 30(1.05)³
The average rate of change in the value of the account over the first 3 years is given by the formula:
⇒ (V(3) - V(0)) / (3 - 0)
⇒ (30(1.05)³ - 30) / 3
⇒ $3.15/year
Hence, the average rate of change in the value of the account over the first 3 years is approximately $3.15/year

How much sand do you need to add to 3.2m^3 of soil with 40% sand in order to make a soil with 60% sand
Answer:
[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]
Step-by-step explanation:
From the question we are told that:
Total soil [tex]N=3.2m^3[/tex]
Initial sand percentage [tex]S_1=40\%[/tex]
Final sand percentage[tex]s_2=60\%[/tex]
Generally the sand and other particles division is mathematically given by
[tex]40\% of 3,2=1.28[/tex]
and
[tex]60\% of 3.2=1.92[/tex]
Generally what will make 60\% of 3.2 40\% is mathematically given by
[tex]x=1.92*0.4\\x=4.8[/tex]
Generally the sand to be added is mathematically given by
[tex]4.8sand-3.2sand =1.6m^3[/tex]
Therefore

The rule is circle and the area of the circle finds using following formula :
Circle area = pi × radius^2
Circle area = 3.14 × 1^2
Circle area = 3.14

What is volume?Volume is amount of substance a container can hold in its capacity. Volume of cylinder is π[tex]r^{2} h[/tex] in which r is radius and h is height of cylinder.
How to calculate volume?We have been given that the diameter of cylinder be 2 inches and height be 10 inches.We have to find the volume of cylinder.
Volume of cylinder=π[tex]r^{2} h[/tex]
Radius=2/2
=1 inch
Now put the value of radius and height in the formula of volume.
Volume=3.14*1*10

Sherry and Karl both started their hike with a small bottle filled with water. Tia started her hike with a larger that was 1/2 full. At the end of the hike, Sherry and Tia’s bottles were each half filled with water. Karl’s bottle was filled 1/3 filled with water. Who has the most water left? Construct a math argument to support your answer.
Answer:
The person with the most water left is;
Tia
Step-by-step explanation:
The parameters given in the question are;
The volume of water Sherry and Karl both started their hike with = 1 small bottle each
The volume of water Tia started her hike with = 1/2 of a larger bottle of water
The volume of water Sherry had at the end of the hike = 1/2 of the small bottle of water
The volume of water Tia had at the end of the hike = 1/2 of the large bottle of water
The volume of water Karl had at the end of the hike = 1/3 of the small bottle of water
Let 'x' and 'y' represent the sizes of the bottles of water with Sherry and Karl respectively and let 'Z' represent the size of the bottle of water Tia started the hike with, we have;
The volume water with Tia at the end of the hike = 1/2·x
The volume water with Karl at the end of the hike = 1/2·y
The volume water with Tia at the end of the hike = 1/2·Z
Given;
Z > x
Z > y
∴ 1/2·Z > 1/2·x
1/2·Z > 1/3·y
Therefore, Tia with half of the larger bottle of water at the end of the hike, 1/2·Z has the most water left.

The straight line PQ with P(1,6) and Q(-6, 1). PQ is mapped onto P'Q' by a reflection in the line = 2. What are the coordinates of P
Answer:
[tex]P' = (1,-2)[/tex]
Step-by-step explanation:
Given
[tex]P = (1.6)[/tex]
[tex]Q = (-6,1)[/tex]
Reflection over: [tex]y = 2[/tex]
Required
Determine the coordinates of P'
From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2
Since we are to reflect over y = 2, only the y coordinate of P will be affected.
The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]
So, what to do is:
First, calculate the difference between the y coordinates of P and the line of reflection.
The y coordinate of P is 6 and the line of reflection is at y = 2.
So, the difference is: 6 -2 = 4
Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'
y coordinate of P' = 2 - 4 = -2
Hence, the coordinate of P' is: (1,-2)

Answer:
Please find below. Fill in the table with the values of y given below.
Step-by-step explanation:
For question 5, you should substitute the different values of x into the equation y =x^2 +4
So, when
x = -3, y = (-3)^2 +4 = 9+4 = 13
x = -2, y = (-2)^2 +4 = 4+4 = 8
x = -1, y = (-1)^2 + 4 = 1+4 = 5
x = 0, y = 0^2 + 4 = 4
x = 1, y = 1^2 +4 = 1+4 = 5
x = 2, y = 2^2 +4 = 8
x = 3, y = 3^2 + 4 = 13
x = 4, y = 4^2 + 4 = 20
For question 6, you need to find the nth term or a formula of y in terms of x.
For this, find the common difference between each of the consecutive values of y.
This is 5
So, the start if our equation is going to be ‘y = 5x’
Now, to find the ‘+c’ part, can be calculated by substituting the value of y when x = 1 into the y = 5x
So,
y = 5x + c
13 = 5 + c
Rearrange the find that c = 8
Therefore, the nth term formula = 5x + 8

A bag contains 55 coins of $1 and ¢50 denominations. Find the number of coins of each denomination, if the total amount in the bag is $40.
Answer:
Number of $1 coins are 25 and number of 50 cent coins are 30.
Step-by-step explanation:
Let's set up the equations.
Let there are x number of $1 coins
There are y number of 50 cent coins
So, x+y =55
1 x+0.50 y =40
Solve the equations for x and y.
Solve the first equation for y.
y=55-x
Substitute y as 55-x into the second equation.
1 x+0.50(55-x)=40
Solve the equation for 'x'.
Distribute the 0.50 to get rid the ( ).
1 x+27.5-0.50 x= 40
Combine like terms
0.50 x +27.5=40
Subtract both sides 27.5
0.50 x =12.5
Divide both sides by 0.50
x=25
Now, plug in x as 25
y=55-25
y=30
So, number of $1 coins are 25 and number of 50 cent coins are 30.

Of the marbles in a bag, 5 are blue, 2 are white, and 2 are yellow. Sandra will randomly choose one marble from the bag.
Answer:
[tex]\dfrac{2}{9}[/tex]
Step-by-step explanation:
Given that,
A bag contains 5 blue, 2 white and 2 yellow marbles.
We need to find the probability of choosing a white marble from the bag.
Total no. of outcomes = 5+2+2
= 9
No. of white marbles = 2
Required probability,
[tex]P=\dfrac{2}{9}[/tex]
So, the probability of choosing a white marble is equal to [tex]\dfrac{2}{9}[/tex].

What is Transformation?A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
When we scale a triangle by some factor, neither its shape nor size change. The image corresponds to the previous image.
The horizontal translation of x coordinate is either horizontally right or horizontally left depending on the positive or negative value of x - coordinate.
Depending on the positive or negative value of the y - coordinate, the y coordinate is translated vertically up or down.
Here (8 ,4) shows there is shifting Horizontally right (x+ 8) and there is shifting Vertically up (y + 4).
