PLEASE SHOW WORK
Answers
The expression [tex]\sqrt{\sqrt{x1\⁰} }\sqrt{\sqrt{x\³ }}[/tex] is equivalent to 10 for [tex]x = 10^{(8/15)}[/tex].
What are exponents?In mathematics, an expοnent (alsο called pοwer οr index) is a shοrthand nοtatiοn used tο represent the repeated multiplicatiοn οf a number by itself.
We can simplify the given expressiοn using the prοperties οf expοnents and rοοts.
First, we can simplify the expression inside the first square root as:
√√x1⁰ = [tex]\rm \sqrt{(x^{10})^{(1/4)} }= (x^{10})^{(1/8)} = x^{(10/8)} = x^{(5/4)}[/tex]
Next, we can simplify the expression inside the second square root as:
[tex]\sqrt{(\sqrt{x\³})} = \sqrt{(x^3)^{(1/4) }}= (x^3)^{(1/8)} = x^{(3/8)[/tex]
Therefore, the entire expression becomes:
[tex]\sqrt{(\sqrt{x1\⁰)}} (\sqrt{(\sqrt{x\³})} = x^{(5/4)} * x^{(3/8) }= x^{(15/8)}[/tex]
Now, we need to find the value of x that makes this expression equal to 10.
[tex]x^{(15/8) }= 10[/tex]
Taking the eighth power of both sides:
[tex]x^{15} = 10^8[/tex]
Taking the 15th root of both sides:
[tex]x = (10^8)^{(1/15)}[/tex]
[tex]x = 10^{(8/15)}[/tex]
the equivalent expression is:
[tex]\sqrt{\sqrt{x1\⁰} }\sqrt{\sqrt{x\³ }}= x^{(5/4) }* x^{(3/8)} = x^{(15/8)} = (10^{(8/15)})^{(15/8)} = 10[/tex]
Therefore, the expression [tex]\sqrt{\sqrt{x1\⁰} }\sqrt{\sqrt{x\³ }}[/tex] is equivalent to 10 for [tex]x = 10^{(8/15)}[/tex].

We are given that angle theta 1 (θ1) is 45 degrees, angle theta 2 (θ2) is 60 degrees, and the height of the column BC is 95.62 meters. We want to find the height of the house AB, which we'll call "h".
First, we can use trigonometry to find the length of segment CD. Since we know angle θ2 and the length of BC, we can use the tangent function:
tan(θ2) = opposite / adjacent
tan(60°) = d / 95.62
d = 95.62 * tan(60°)
d ≈ 165.30 meters
Now we can use the fact that angles ABD and CBD are complementary to find the length of segment AD:
tan(θ1) = opposite / adjacent
tan(45°) = h / (d + 165.30)
h = (d + 165.30) * tan(45°)
h ≈ 165.30 meters
Therefore, the height of the house is approximately 165.30 meters.

A high school in a small town always has its homecoming day and parade on the first Saturday in October. From historical records, it has been determined that the probability of rain during the parade is 0.16. Amina will attend the high school for the next four years and plans to play in the marching band in the parade.(a) What is the probability that it will not rain on the homecoming parade in Amina's first year?(b) What is the probability that it will not rain on any of the homecoming parades during Amina's four years at the school? (Round your answer to three decimal places.)(c) What is the probability that it will rain on Amina's parade at least once during her four years of attendance? (Round your answer to three decimal places.)
Answers
a) The probability that it will not rain on the homecoming parade in Amina's first year is 0.84. b) The probability that it will not rain on any of the homecoming parades during Amina's four years at the school is 0.49. c) The probability that it will rain on Amina's parade at least once during her four years of attendance is 0.51.
We can solve this problem as:
a) This can be calculated by subtracting the probability of rain during the parade (0.16) from 1.
So, the probability is,
1 - 0.16 = 0.84.
b) This can be calculated by taking the probability of no rain (0.84) and multiplying it by itself four times.
So, the probability is,
0.84^4 = 0.49.
c) This can be calculated by subtracting the probability of no rain (0.49) from 1.
So, the probability is,
1 - 0.49 = 0.51.
In conclusion, the probability that it will not rain on the homecoming parade in Amina's first year is 0.84, the probability that it will not rain on any of the homecoming parades during Amina's four years at the school is 0.49, and the probability that it will rain on Amina's parade at least once during her four years of attendance is 0.51.

Answers
The exponential function of the line that goes through points (0, 20) and (2, 180) is y = 20 × 3ˣ.
What is the exponential function of a line that goes through the points (0,20) and (2,180)?To find the exponential function of a line that goes through two points, we need to use the general form of the exponential function:
y = a × bˣ
where a is the initial value, b is the base, and x is the independent variable (usually time).
We can use the two points given to find the values of a and b.
Let's start with the point (0, 20):
y = a × bˣ
Plug in x = 0 and y = 20
20 = a × b⁰
20 = a × 1
a = 20
Next, let's use the point (2, 180):
y = a × bˣ
Plug in x = 2 and y = 180
180 = 20 × b²
b² = 180/20
b² = 9
b = 3
Now, plug these values into y = a × bˣ
Therefore, the exponential function y = 20 × 3ˣ

Explain how the amount of a down payment affects your monthly mortgage payments.
Nick found his dream home that has a purchase price of $192,000. Nick earns $3,325 a month and wants to spend no more than 30% of his income on his mortgage payment. He has saved up $35,000 for a down payment. Nick is considering the following loan option: 20% down, 30 year at a fixed rate of 6. 25%. What modification can be made to this loan to make it a viable option, given Nick’s situation?
Answers
This modification will reduce the amount he needs to borrow from the lender and thus lower his monthly mortgage payments.
The down payment is the amount of money that the buyer pays upfront towards the purchase price of the property. The more significant the down payment, the less money the buyer has to borrow from the lender, and this can have a significant impact on the monthly mortgage payments.
In the case of Nick, he has saved up 35,000 for a down payment, which is approximately 18% of the purchase price of the house. If he decides to go with the 20% down payment option, he will need to pay 38,400 upfront, which is 20% of 192,000. The remaining 153,600 will be the amount he borrows from the lender.
Now, let's assume that Nick has taken a 30-year fixed-rate mortgage at 6.25% interest. If he decides to pay 20% down payment, his monthly mortgage payments would be approximately 940. However, Nick wants to spend no more than 30% of his income on his mortgage payment, which is 997.50 per month (30% of 3,325). Therefore, the modification that can be made to this loan to make it a viable option is to reduce the loan amount.
If Nick reduces the loan amount to 153,000, his monthly mortgage payment will be approximately 910, which is within his budget. To achieve this, he will need to increase his down payment to 39,000, which is 20.3% of the purchase price. This modification will reduce the amount he needs to borrow from the lender and thus lower his monthly mortgage payments.
In summary, a larger down payment reduces the amount borrowed from the lender and, consequently, lowers the monthly mortgage payments. To make the loan option viable, Nick needs to increase his down payment to reduce the loan amount and meet his budget.

Answers
We will thus require 62 cubοid bricks tο create the wall, tο the clοsest whοle brick.
What shape dοes a brick have?A nοrmal brick is a cubοid, a three-dimensiοnal structure with six rectangular faces.
We need tο have at minimum 42/18 = 2.33 rοws mοre bricks because the wall is 42 inches tall, and each brick is 18 inches tall. We require three rοws οf bricks since we can't have a half rοw.
We require 144/7 = 20.57 bricks each rοw because the wall is 144 inches lοng and each brick is 7 inches lοng. There must be 21 bricks each rοw because we cannοt have half bricks.
The first rοw requires 21 whοle bricks. If a brick is sliced in half, the οther half can be used οn the οther end οf the identical rοw.
21 whοle bricks are alsο required fοr the secοnd rοw. Fοr the remainder οf the rοw, we need οnly 20 full bricks since we can utilise the half-brick we cut during the initial rοw just at start οf the secοnd rοw.
The third rοw requires 21 whοle bricks. We have a spare half-brick that we may utilize at the cοnclusiοn οf the third rοw since we utilized οne in the first rοw.
Hence, 62 cοmplete bricks are needed, which equals 21 + 20 + 21.

Rowan is taking his siblings to get ice cream. they can't decide whether to get a cone or a cup because they want to get the most ice cream for their money. if w = 4 in, x =6 in, y = 6 in, z = 2 in, and the cone and cup are filled evenly to the top with no overlap, which container will hold the most ice cream? use 3.14 for π, and round your answer to the nearest tenth.
Answers
The cup will hold more ice cream than cone since volume of cup is 169.6 cubic inches which is greater than volume of 25.1 cubic inches.
The volume of a cone is given by the formula:
V= 1/3.π[tex]r^{2}[/tex]h
where r is the radius of the circular base and h is the height.
The volume of a cylinder is given by the formula:
V= π[tex]r^{2}[/tex]h
where r is the radius of the circular base and h is the height.
Assuming that the height of both the cone and the cup is the same, we can compare their volumes by comparing their radii.
For the cone, the radius r is equal to half the diameter of the circular base, which is equal to w/2 = 2 in.
The height of the cone is equal to y, which is 6 in.
V= 1/3.π[tex]r^{2}[/tex]h= 1/3.π[tex]2^{2}[/tex]6
For the cup, the radius r is equal to x/2 = 3
The height of the cup is equal to y, which is also 6 in.
Using these values, we can calculate the volume of the cup as:
[tex]V_cup[/tex]= π[tex]r^{2}[/tex]h=π[tex]3^{2}[/tex]6
Therefore, the cup will hold more ice cream than the cone.

What are the values of a and b?
Answers
The values of a and b are a = 0 and b = -3, and the quadratic equation of the curve is y = (x - 8)² - 3.
What is a quadratic function?
A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.
The vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
In this case, the vertex is (8, -3).
So we have -
y = a(x - 8)² - 3
To find the value of a, we need one more point on the parabola.
Let's use the fact that the curve is symmetric about the vertex, so there must be another point with the same y-value, but reflected across the vertex.
Since the vertex is at (8, -3), the reflection would be at (8 - 2a, -3).
So we have -
-3 = a(8 - 2a - 8)² - 3
Simplifying -
0 = a(2a)²
0 = 4a³
So either a = 0 or a is undefined (i.e. the parabola is a horizontal line). But we know the curve has a minimum, so it can't be a horizontal line.
Therefore, a must be 0.
Substituting this into our equation, we get -
y = 0(x - 8)² - 3
y = (x - 8)² - 3
Therefore, a = 0 and b = -3, and the equation is y = (x - 8)² - 3.

John invest R500, at 12% per annum using simple interest for 4 years. How much money will John have at the end of 4 years?
Answers
Simple Interest = (Principal x Rate x Time)
where:
Principal = R500 (the amount invested)
Rate = 12% per annum = 0.12 (expressed as a decimal)
Time = 4 years
So, the simple interest earned by John over 4 years is:
Simple Interest = (500 x 0.12 x 4) = R240
To find the total amount of money John will have at the end of 4 years, we need to add the simple interest to the principal:
Total amount = Principal + Simple Interest = 500 + 240 = R740
Therefore, John will have R740 at the end of 4 years.
Answer:
The total amount he has at the end is ₹740.
Step-by-step explanation:
Simple Interest = [tex]\frac{PRT}{100}[/tex]
= [tex]\frac{500 * 12 * 4}{100}[/tex] = ₹240
Total amount he has at the end of 4 years = Principal + Interest
= ₹500 + ₹240
= ₹740
When Hector found a rare coin a few years ago, it was worth $190. Since then, it has been increasing in value by the same percentage each year. One year after
Hector found the coin, it was worth $209.
If c(n) represents the value in dollars of the coin n years after Hector found it, which expression is equal to c(n)?
190 (0.01^n)
190 (0.1^n)
190 (1.01^n)
190 (1.1^n)
Answers
The required expression represents the value in dollars of the coin n years after Hector found is [tex]$c(n) = 190 \times (1.1)^n$[/tex].
How to find the function of time?Let's call the percentage increase in value each year "r". We know that after one year, the coin was worth $209, which is 209/190 = 1.1 times what it was worth when Hector found it. So we can set up an equation:
[tex]$190 \times (1 + r)^1 = 209$[/tex]
Simplifying this equation,
[tex]$1 + r = \sqrt[1]{\frac{209}{190}}$[/tex]
1 + r = 1.1
r = 0.1
So the percentage increase in value each year is 10%. To find the value of the coin "n" years after Hector found it, we can use the formula:
[tex]$c(n) = 190 \times (1 + r)^n$[/tex]
Substituting the value we found for "r", we get:
[tex]$c(n) = 190 \times (1.1)^n$[/tex]
So the expression for the value of the coin "n" years after Hector found it is:
[tex]$c(n) = 190 \times (1.1)^n$[/tex]
Thus, required expression represents the value in dollars of the coin n years after Hector found is [tex]$c(n) = 190 \times (1.1)^n$[/tex].

b. what type of single transformation maps triangle A onto Triangle A''?
Answers
Answer:
90° CCWy = 0 (x-axis)reflection in the line x+y=-1Step-by-step explanation:
You want to know the parts of the composition of transformations that will map triangle A to A', then to A''. You also want to know what single transformation accomplishes the same thing.
A. Rotation, ReflectionThe long side of triangle A points "south". In triangle A', it points "east". To transform a segment pointing south to one pointing east requires a rotation of +90°, or 90° CCW.
The long side of triangle A' lies along the line y=1. In triangle A'', it lies on the line y=-1. The line of reflection is halfway between these values, at ...
y = (1 +(-1))/2 = 0/2 = 0
The line of reflection is y=0, the x-axis.
B. Single transformationWe know the transformation involves a reflection. The line of reflection can be found by finding the midpoints of the original and final vertices of the triangle.
The midpoint of the largest acute angle's vertex is ...
((2, -3) +(2, -3))/2 = (2, -3)
The midpoint of the right angle vertex is ...
((0, -3) +(2, -1))/2 = (1, -2)
The line through these two points is ...
x +y = -1
The transformation of A to A'' is a reflection in the line x+y=-1.
