Answer:
Step-by-step explanation:
the 1st number of this series is x
because this series has 384 consecutive odd integers => this is a arithmetic sequence with d = 2
=> the sum of this series = \(384x+384(384-1) =384x+147072\)
but this series has a sum that is the perfect fourth power of a positive integer
=> 384x + 147072 = k^4 ( k is a positive integer)
to have the smallest sum => x must be the smallest odd integer.
+) with the sum = 104 976 => x isnt a integer => unreasonable
+) with the sum = 20 736 => x = -329
+) with the sum = 10000 =>x isnt a integer => unreasonable
+) with the sum = 1296 => x isnt a integer => unreasonable
+) with the sum = 38 416 => x isnt a integer => unreasonable
=> the smallest sum is 20 736
Answer:
The smallest sum is 20 736!

Answer:1/9
Step-by-step explanation:
Any number to the power of 0 will equal 1, and -3 to the power of 2 is 9
whats 2+2 pls i have a test tomorrow i need to pass it
2x-9
X =
X +5
Use the triangle shown above to solve for x.
A
The value of x is 14.
We know in an isosceles triangle an isosceles polygon is a polygon with at least two sides of equal length.
We have two sides measured 2x-9 and x+ 5.
From the figure the length of sides are equal then
2x-9 = x+ 5
2x- 9- x = 5
x-9 = 5
Add 9 to both sides of the equation:
x - 9 + 9 = 5 + 9
x= 14
Thus, the value of x is 14.

Mrs. Liu is mixing glue and shaving cream to make snowman puff paint for her art class. The ounces of glue to ounces of shaving cream must have a ratio of 7:15. If she is mixing 56 ounces of glue, how much shaving cream does she need?
The ounces of shaving cream will be 230 ounces.
How to illustrate the ratio?Ratio in Mathematics simply demonstrates how many times one number can be able to fit into another number. It should be noted that ratios contrast two numbers by dividing them. In this case, A/B will be the formula if one is comparing one variable (A) to another variable (B).

Marissa decides to save AND invest for retirement. She makes an initial deposit of $2000 in her savings account which earns 1.5% annually. Her contributions are $150 a month. Then, she makes an initial deposit of $1,000 in the US stock market through an index fund contributing $300 a month with a 6.8% return annually. What is the balance of Marissa’s retirement account after 30 years?
Using compound interest formula, her balance after retirement is $430797.77
What is Marissa's BalanceTo calculate the balance of Marissa's retirement account after 30 years, we need to determine how much her savings account and index fund will be worth after 30 years, taking into account the interest earned and her monthly contributions.
First, we'll calculate the balance of her savings account:
Initial deposit: $2000
Interest rate: 1.5%
Monthly contribution: $150
Number of months: 30 years * 12 months/year = 360 months
Using the compound interest formula, the balance of her savings account after 30 years will be:
2000*(1+0.015/12)^360 + 150*(((1+0.015/12)^360-1)/(0.015/12))
A = $71280.33
Next, we'll calculate the balance of her index fund:
Initial deposit: $1000
Interest rate: 6.8%
Monthly contribution: $300
Number of months: 30 years * 12 months/year = 360 months
Using the compound interest formula, the balance of her index fund after 30 years will be:
A = 1000*(1+0.068/12)^360 + 300*(((1+0.068/12)^360-1)/(0.068/12))
A = $359517.44
Then we can add the balance of both the savings account and the stock market to get the total balance of Marissa's retirement account.
Her balance = $71280.33 + $359517.44 = $430797.77
Please note that the above answer is an estimation, in reality there are other factors such as taxes, inflation, fees, and market conditions that should be considered in a real-world scenario.

Question 8(Multiple Choice Worth 2 points)
(Writing Two-Step Equations MC)
A new gaming chair costs $455.95. You have already saved $155.95 and earn $37.50 each week babysitting. Write and solve an equation to determine how many weeks, w, you must babysit to earn enough money to buy the new gaming chair.
37.5 + 155.95w = 455.95; w = 8
37.5w + 155.95 = 455.95; w = 8
37.5w − 155.95 = 455.95; w = 16
37.5w − 455.95 = 155.95; w = 16
37.5w + 155.95 = 455.95; where w = 8; signifies the number of weeks required to babysit the business in order to purchase the gaming chair.
How do equations work?A mathematical formula that connects two expressions with the equals sign (=) expresses the equality of the two expressions. For instance, in English, an equation is any properly stated formula that consists of two expressions linked by the equals sign, whereas in French, an equation is described as containing one or more variables. To solve a variable equation, identify the values of the variables that cause the equality to hold true. The answer is known as the values of the variables that must satisfy the equality.
Equations can be categorized as identities or conditional equations.
w = (455.95-155.95)/(37.50)
=300/37.50
=8
So, number of weeks = 8
As a result, w = 8 and 37.5w + 155.95 = 455.95 is the solution.

The average rate of change for the interval from x = 7 to x = 8 is 35.
To calculate the average rate of change for the interval from x = 7 to x = 8, we need to find the difference in y- values and divide it by the difference inx-values within that interval.
Let's calculate it step by step using the given table
For the interval from x = 7 to x = 8 x1 = 7, y1 = -37 x2 = 8, y2 = -2 Difference in y- values Δy = y2- y1 = -2-(- 37) = 35
Difference inx-values Δx = x2- x1 = 8- 7 = 1
Average rate of change = Δy/ Δx = 35/ 1 = 35
Thus, the average rate of change for the interval from x = 7 to x = 8 is 35. Note: It's important to mention that the values calculated then are grounded solely on the given data. Please insure you corroborate the delicacy of the handed data and environment before using the answer in any important or critical operations.

(06.05 MC)
a Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is
seeds she planted. The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks.
Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks. (4 points)
Part B: What are the units of measurement for the composite function in Part A? (2 points) (2
Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)
A) Composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks is f[s(w)] = 50w + 25.
B) The unit of measurement for the composite function is flowers.
C) Number of the flowers for 30 weeks will be 1525.
What is a composite function?A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is f[s(w)] = 50w + 25. and the number of flowers for 30 weeks is 1525.
Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks.
From the given data we will find the function for the number of flowers with time.
f(s) = 2s + 25
We have s(w) = 25w
f[(s(w)]=2s(w) + 25
f[(s(w)] = 2 x ( 25w ) +25
f[s(w)] = 50w + 25.
Part B: What are the units of measurement for the composite function in Part A
The expression f[s(w)] = 50w + 25 will give the number of the flowers blooming over a number of the weeks so the unit of measurement will be flowers.
Part C: Evaluate the composite function in Part A for 30 weeks.
The expression f[s(w)] = 50w + 25 will be used to find the number of flowers blooming in 30 weeks put the value w = 30 to get the number of the flowers.
f[s(w)] = 50w + 25.
f[s(w)] = (50 x 30) + 25.
f[s(w)] = 1525 flowers.
Therefore the composite function is f[s(w)] = 50w + 25. unit will be flowers and the number of flowers in 30 weeks will be 1525.
