A ball is dropped from a height of 20 feet. It hits the ground and bounces up half as high as it fell. This is true for each successive bounce. What height does the ball reach on the fourth bounce
Answers
Answer:
1.25 m
Step-by-step explanation:
Given that :
Initial height of drop = 20 meters
Rebound after each drop = 1/2 of height
Height after 4th rebound = 5th term of a geometric series
An = a1 * r^(n-1)
a1 = first term = initial drop height
r = common ratio = ratio of rebound per drop = 1/2 = 0.5
A5 = 20 * 0.5^(5 - 1)
A5 = 20 * 0.5^4
A5 = 20 * 0.0625
A5 = 1.25 m
Hence height after 4 reboubd = 1.25 m
Using another method :
1st bounce height = 20 * 0.5 = 10
2nd bounce height = 10 * 0.5 = 5
3rd bounce height = 5 * 0.5 = 2.5
4th bounce height = 2.5 * 0.5 = 1.25

Answers
Answer:
x = 24°
Step-by-step explanation:
the sum of the interior angles in a triangle = 180°
so:
(2x + 5°) + 64° + 3x - 9° = 180°
combine like terms:
5x + 60° = 180°
subtract 60° from each side of the equation:
5x = 120°
x = 24°
5. Write an equivalent expression to 1/4 (24x + 7 – 12x).
Answers
Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses: (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7). This is an acceptable answer. There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.

The function f(x) = 34,000(1.05)* can be used to
determine Noah's cost of living in Houston over time.
What does the 1.05 represent?
A The cost of living will increase by approximately 1% each year
B The cost of living will decrease by approximately 1% each year
C The cost of living will increase by approximately 5% each year
D The cost of living will decrease by approximately 5% each year
Answers
9514 1404 393
Answer:
C The cost of living will increase by approximately 5% each year
Step-by-step explanation:
If we assume your function is ...
[tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]
Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.
Noah's cost of living is increasing about 5% per year.
Find the mean and the standard deviation of the data set {5, 8, 1, 2, 10}.
Answers
5 + 8 + 1 + 2 + 10 = 26 (divided by) 5 = 5.2
The mean and the standard deviation of the data set is 5.2 and 3.429.
What is Arithmetic Mean?The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.
We have,
Data: {5, 8, 1, 2, 10}.
So, the mean of data
= (5+ 8 + 1 + 2 +10)/ 5
= 5.2
Then, the Value of Deviations
-0.2, 2.8, -4.2, -3.2, 4.8
So, the variance is
= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5
= 11.76
And, Standard deviation is

A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees and totaled $411
Answers
Answer:
Cost of 1 bushes = a = $9
Cost of 1 tree = b = $73.5
Step-by-step explanation:
Given:
13 bushes and 4 trees cost = $411
Missing;
6 bushes and 2 trees cost = $201
Find:
Value of bushes and tree
Computation:
Cost of 1 bushes = a
Cost of 1 tree = b
So,
13a + 4b = 411 ...........eq1
6a + 2b = 201 ................eq2
From Eq1 and Eq2
Cost of 1 bushes = a = $9
From eq 1
13a + 4b = 411
13(9) + 4b = 411
Cost of 1 tree = b = $73.5
A stock can go up, go down, or stay unchanged. How many possibilities are there if you own 3 stocks?
Answers
Answer:
There are 27 different possible outcomes.
Step-by-step explanation:
Assuming that you have 3 different stocks:
First, we need to find the number of events and the number of possible outcomes for each event.
Here we can assume that each one of the stocks is a event, and the number of possible outcomes for each one are:
Stock 1: 3 options (up, down, stay)
Stock 2: 3 options (up, down, stay)
Stock 3: 3 options (up, down, stay)
The total number of possible outcomes is equal to the product of the numbers of options for all the events.
Then the total number of possibilities is:
C = 3*3*3 = 27
A new laptop costs $1100 and has a new book value of $375 after 2 years. Find the linear model V(t)=Mx+b
Answers
Answer:
- 362.5t + 1100
Step-by-step explanation:
Given :
Value, = v ; time, = t
t1, v1 = (0, 1100)
t2, v2 = (2, 375)
Slope, m = v2 - v1 / t2 - t1
m = (375 - 1100) / (2 - 0)
m = - 725 / 2
m = - 362.5
v - v1 = m(t - t1)
v - 1100 = - 362.5(t - 0)
v - 1100 = - 362.5t
v = - 362.5t + 1100
