Answer:
1.75 miles
Step-by-step explanation:
Zeno's friend's house is two miles away. He travels half the distance in one hour.
0.5 × 2 = 1
The second hour, his horse travels half the remaining distance.
0.5 × 1 = 0.5
The third hour, his horse travels half the remaining distance.
0.5 × 0.5 = 0.25
1 + 0.5 + 0.25 = 1.75
Zeno travels 1.75 miles in three hours.

Step-by-step explanation:
In order to calculate the debt ratio of LotsofDebt, Inc and LotsofEquity, Inc. we would have to make the following calculations:
Debt Ratio = Debt/Assets
According to the given data we have the following:
LotsofDebt, Inc Debt=$30 million
LotsofDebt, Inc Asset=Debt + Equity = $30 million + $2 million = $32 million
Therefore, LotsofDebt, Inc Debt Ratio =$30 million/$ 32 million
LotsofDebt, Inc Debt Ratio= 93.75%
LotsofEquity, Inc. Debt=$2 million
LotsofEquity, Inc Asset= Debt + Equity = $2 million + $30 million
LotsofEquity, Inc Debt Ratio = $2 million/$32 million
LotsofEquity, Inc Debt Ratio = 6.25%
In order to calculate the equity multiplier of LotsofDebt, Inc and LotsofEquity, Inc. we would have to make the following calculations:
equity multiplier =Assets/Equity
equity multiplier LotsofDebt, Inc.=$32 million/$2 million
equity multiplier LotsofDebt, Inc= 16
equity multiplier LotsofEquity, Inc=$32 million/$30 million
equity multiplier LotsofEquity, Inc = 1.0666666667
In order to calculate the debt-to-equity of LotsofDebt, Inc and LotsofEquity, Inc. we would have to make the following calculations:

Write the equations after translating the graph of y = |x|: one unit up,
Answer:
[tex]g(x) = |x| + 1[/tex]
Step-by-step explanation:
Given
[tex]y = |x|[/tex]
Required
Translate 1 unit up
Start by replacing y with f(x)
[tex]f(x) = |x|[/tex]
To translate an the graph of an absolute function upward, you make use of the formula;
[tex]g(x) = f(x) + k[/tex]
Where k is the number of units
In this case; [tex]k = 1[/tex]
Hence;
[tex]g(x) = f(x) + k[/tex]
Substitute [tex]k = 1[/tex]
[tex]g(x) = f(x) + 1[/tex]
Substitute [tex]f(x) = |x|[/tex]
[tex]g(x) = |x| + 1[/tex]
Hence, the resulting equation is [tex]g(x) = |x| + 1[/tex]
Evaluate the following integrals
Answer:
a. (24 ln 2 − 7) / 9
b. x tan x + ln|cos x| + C
Step-by-step explanation:
a. ∫₁² x² ln x dx
Integrate by parts.
If u = ln x, then du = 1/x dx.
If dv = x² dx, then v = ⅓ x³.
∫ u dv = uv − ∫ v du
= (ln x) (⅓ x³) − ∫ (⅓ x³) (1/x dx)
= ⅓ x³ ln x − ∫ ⅓ x² dx
= ⅓ x³ ln x − ¹/₉ x³ + C
= ¹/₉ x³ (3 ln x − 1) + C
Evaluate between x=1 and x=2.
[¹/₉ 2³ (3 ln 2 − 1) + C] − [¹/₉ 1³ (3 ln 1 − 1) + C]
⁸/₉ (3 ln 2 − 1) + C + ¹/₉ − C
⁸/₉ (3 ln 2 − 1) + ¹/₉
⁸/₃ ln 2 − ⁸/₉ + ¹/₉
⁸/₃ ln 2 − ⁷/₉
(24 ln 2 − 7) / 9
b. ∫ x sec² x dx
Integrate by parts.
If u = x, then du = dx.
If dv = sec² x dx, then v = tan x.
∫ u dv = uv − ∫ v du
= x tan x − ∫ tan x dx
= x tan x + ∫ -sin x / cos x dx
= x tan x + ln|cos x| + C

1. What do you notice about how the angles fit together around a point?
2. What is the measure of a straight angle?
3. Describe the relationship amoung the measure of the angles of ∆ABC
4. The triangle sum theorem states that forma ∆ ABC, m<A + m<A = 180°. Is this true? Explain
1. The angles form a straight angle
2. A straight angle is defined to be 180 degrees
3. The three angles of any triangle always add to 180, as the diagram shows.
4. This is false. We need to add the three different angles A,B,C to get 180. Adding angle A to itself may not lead to 180. A+A = 180 only happens when angle A is a right angle (90 degree angle).
Ricardo has a square hot tub. He wants to build a square pool next to it that is a dilation of the hot tub using a scale factor of 5. Point Q is the center of dilation. Square A B C D is dilated to created square A prime B prime C prime D prime. The length of B prime C prime is 24 feet. If the pool is to be 24 ft on each side, what is the length of one side of the hot tub? 4 ft 4.8 ft 6 ft 7.2 ft
Answer:
[tex]\boxed{Side \ Length \ of \ hot \ tub = 4.8\ ft.}[/tex]
Step-by-step explanation:
Scale Factor = 5
Also,
B'C' = 24 feet
Since both are squares so both have all sides equal.
Sqaure A'B'C'D' is dilated by a scale factor of 5
So,
AB = BC = CD = DA = 24/5 = 4.8 ft.
The length of one side of the hot tub is 4.8 feet and this can be determined by using the concept of dilation.

In a random sample of 500 handwritten zip code digits, 464 were read correctly by an optical character recognition (OCR) system operated by the U.S. Postal Service (USPS). USPS would like to know whether the rate is at least 90% correct.
Required:
Do the data provide evidence that the rate is at least 90% at a 0.05?
Answer:
z= 2.38
P = 0.008656
Step-by-step explanation:
Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072
We formulate our null and alternate hypothesis as
H0 = 0.9 ; H0 > 0.9
The degree of confidence = 90%
z₀.₀₅ = 1.645 for α= 0.05
We use the test statistic
z= x- np/√npq
z= 466-500 *0.9/ √500 * 0.9(1-0.9)
z= 466- 450/ √45
z= 16/6.7082
z= 2.38
As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.
If H0 is true the P value is calculated as
P = 1- Ф( 2.38)
P = 1-0.991344=0.008656
Gravel is being dumped from a conveyor belt at a rate of 20 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. How fast is the height of the pile increasing when the pile is 11 ft high
Answer:
0.0526ft/minStep-by-step explanation:
Since the gravel being dumped is in the shape of a cone, we will use the formula for calculating the volume of a cone.
Volume of a cone V = πr²h/3
If the diameter and the height are equal, then r = h
V = πh²h/3
V = πh³/3
If the gravel is being dumped from a conveyor belt at a rate of 20 ft³/min, then dV/dt = 20ft³/min
Using chain rule to get the expression for dV/dt;
dV/dt = dV/dh * dh/dt
From the formula above, dV/dh = 3πh²/3
dV/dh = πh²
dV/dt = πh²dh/dt
20 = πh²dh/dt
To calculate how fast the height of the pile is increasing when the pile is 11 ft high, we will substitute h = 11 into the resulting expression and solve for dh/dt.
20 = π(11)²dh/dt
20 = 121πdh/dt
dh/dt = 20/121π
dh/dt = 20/380.133
dh/dt = 0.0526ft/min
This means that the height of the pile is increasing at 0.0526ft/min
An open box with no lid has a square base and four sides of equal height. The height is 4 inches
greater than the length and width (which are the same). What are the dimensions of the box if the
volume is 63 cubic inches and the surface area is 93 square inches?
PLEASE SHOW YOUR WORK:) THANK YOU SO MUCH
Answer:
width = length = 3 inches
height = 7 inches
Step-by-step explanation:
If x is the width and length of the base, and y is the height, then:
y = x + 4
The volume of the box is:
63 = x²y
The surface area of the box is:
93 = x² + 4xy
Substitute the first equation into the third.
93 = x² + 4x (x + 4)
93 = x² + 4x² + 16x
0 = 5x² + 16x − 93
0 = (x − 3) (5x + 31)
x = 3
y = 7
Use the second equation to check your answer.
63 = (3)²(7)
63 = 63
Answer:
Length=Width=3
Height=7.
Step-by-step explanation:
First, let's write some equations. So, we have an open box (with no lid) that has a square base. It has a height 4 units more of its width/length.
First, let's write the equation for the volume. The volume of a rectangular prism is:
[tex]V=lwh[/tex]
Recall that we have a square base. In other words, the length and width are exactly the same. Therefore, we can do the following substitution:
[tex]V=(w)wh=w^2(h)[/tex]
Now, recall that the height is four units more than the width/length. Therefore, we can make the following substitution:
[tex]V=w^2(w+4)\\63=w^2(w+4)[/tex]
We can't really do anything with this. Let's next find the equation for the surface area.
So, we have 5 sides (not 6 because we have no lid). The bottom side is a square, so it's area is w^2. Since we have a square base, the remaining four sides will have an area w(w+4). In other words:
[tex]93=w^2+4(w(w+4))[/tex]
The left term represents the area of the square base. The right term represents the area of one of the rectangular sides, times sides meaning four sides. Simplify:
[tex]93=w^2+4w^2+16w\\5w^2+16w-93=0[/tex]
This seems solvable. Let's try it. Trying factoring by guessing and checking.
We can see that it is indeed factor-able. -15 and 31 are the numbers:
[tex]5w^2-15w+31w-93=0\\5w(w-3)+31(w-3)=0\\(5w+3)(w-3)=0\\w=3\\h=w+4=7[/tex]
We ignore the other one because width cannot be negative.
So, the width/length is 3 and the height is 7. We can check this by plugging this into the volume formula:
[tex]63\stackrel{?}{=}(3)^2(7)\\63\stackrel{\checkmark}{=}63[/tex]
What equation results from completing the square and then factoring? x^2+22x=31 A.(x+22)^2=53 B.(x+22)^2=152 C.(x+11)^2=152 D.(x+11)^2=53
Answer:
[tex]\boxed{\mathrm{Option \ C}}[/tex]
Step-by-step explanation:
=> [tex]x^2+22x = 31[/tex]
=> [tex](x)^2+2(x)(11) = 31[/tex]
Since b = 11 , So [tex](11)^2[/tex] needs to be added to both sides
Adding [tex](11)^2[/tex] to both sides
=> [tex](x)^2+2(x)(11)+(11)^2 = 31+(11)^2[/tex]
Completing the square
=> [tex](x+11)^2 = 31+121[/tex]
=> [tex](x+11)^2 = 152[/tex]

(b) Use differentials to estimate the maximum error in the calculated volume. (Round your answer to the nearest integer.)
cm^3
What is the relative error? (Round your answer to three decimal places.)
Answer:
Error in the sphere's surface: 29 [tex]cm^2[/tex] and relative error in surface measure: 0.011
Error in the sphere's volume: 205 [tex]cm^3[/tex] and relative error in the volume measure: 0.017
Step-by-step explanation:
(a)
The measured length (l) of the circumference is 90 cm with an error of 0.5 cm, that is:
[tex]l=2\,\pi\,R=90\,cm\\R=\frac{90}{2\,\pi} \,cm=\frac{45}{\pi} \,cm=14.3239\,\,cm[/tex]
and with regards to the error:
[tex]dl=0.5 \, cm\\dl=2\,\pi\,dR\\dR=\frac{dl}{2\,\pi} =\frac{1}{4\,\pi} cm = 0.0796\,cm[/tex]
then when we use the formula for the sphere's surface, we get:
[tex]S=4\,\pi\,R^2\\dS=4\,\pi\,2\,R\,(dR)\\dS=8\,\,\pi\.(\frac{45}{\pi} \,\,cm)\,(\frac{1}{4\pi}\,cm) =\frac{90}{\pi} \,\,cm^2\approx \,29\,cm^2[/tex]
Then the relative error in the surface is:
[tex]\frac{dS}{S} =\frac{90/\pi}{4\,\pi\,R^2} =\frac{1}{90} =0.011[/tex]
(b)
Use the formula for the volume of the sphere:
[tex]V=\frac{4\,\pi}{3} R^3\\dV=\frac{4\,\pi}{3}\,3\,R^2\,(dR)=4\,\pi\,R^2\,(\frac{1}{4\pi}) \,cm=(\frac{45}{\pi})^2 \,\,cm^3\approx 205\,\,cm^3[/tex]
Then the relative error in the volume is:
[tex]\frac{dV}{V} =\frac{205}{12310.5} \approx 0.017[/tex]
A rectangular waterbed is 8 ft long, 5 fr, wide and 1 ft tall.
How many gallons of water are needed to fill the waterbed?
Assume 1 gallon is 0.13 ft.³ round to the nearest whole gallon
Answer: 308 gallons of water.
Step-by-step explanation:
First find the volume of the water been.
The volume of a rectangular prism uses the formula
V= L * W *H
V = 8 * 5 * 1
V = 40 ft^3
Now we will convert 40ft into gallons using what they gave us that 1 gallon is 0.13 ft^3
[tex]\frac{1}{x} = \frac{0.13}{40}[/tex] which means if 1 gallon is 0.13 cubic feet how much will 40 cubic feet be when converted to gallons.
Solve by cross product.
0.13x = 40 divide both sides by 0.13
x= 308

∫x2/x1−20x2−125dx
Answer:
125/6(In(x-25)) - 5/6(In(x+5))+C
Step-by-step explanation:
∫x2/x1−20x2−125dx
Should be
∫x²/(x²−20x−125)dx
First of all let's factorize the denominator.
x²−20x−125= x²+5x-25x-125
x²−20x−125= x(x+5) -25(x+5)
x²−20x−125= (x-25)(x+5)
∫x²/(x²−20x−125)dx= ∫x²/((x-25)(x+5))dx
x²/(x²−20x−125) =x²/((x-25)(x+5))
x²/((x-25)(x+5))= a/(x-25) +b/(x+5)
x²/= a(x+5) + b(x-25)
Let x=25
625 = a30
a= 625/30
a= 125/6
Let x= -5
25 = -30b
b= 25/-30
b= -5/6
x²/((x-25)(x+5))= 125/6(x-25) -5/6(x+5)
∫x²/(x²−20x−125)dx
=∫125/6(x-25) -∫5/6(x+5) Dx
= 125/6(In(x-25)) - 5/6(In(x+5))+C

Answer:
The minimum svore required to get an A is 85.3.
Step-by-step explanation:
Complete Question
Exam grades: Scores on a statistics final in a large class were normally distributed with a mean of 75 and a standard deviation of 8.
The instructor wants to give an A to the students whose scores were in the top 10% of the class. What is the minimum score needed to get an A?
Solution
Scores in the top 10% of the class will have a minimum greater than the remaining bottom 90% of the class.
If the minimum score for the top 10% of the class is x'
P(X ≤ x') = 90% = 0.90
If the z-score of this minimum score of the top 10%, x', is z'.
P(X ≤ x') = P(z ≤ z') = 0.90
using the z-distribution tables
z' = 1.282
But the z-score of any value is given as the value minus the mean divided by the standard deviation.
z = (x - μ)/σ
So,
z' = (x' - μ)/σ
Mean = 75
Standard deviation = 8
z' = 1.282
1.282 = (x' - 75)/8
x' = (1.282 × 8) + 75 = 85.256
= 85.3 to 3 s.f.

Which of the binomials below is a factor of this trinomial?
x2 - 5x+ 4
O A. X-1
O B. x2 + 4
C. X+4
D. X + 1
Answer:
A
Step-by-step explanation:
To factor x² - 5x + 4, we need to find 2 numbers that have a sum of -5 and product of 4; these 2 numbers are -1 and -4 so the factored version is (x - 1)(x - 4). Since x - 4 is not an answer choice but x - 1 is, the answer is A.
1. Find the sum of the first five (5) terms of the arithmetic progression
60 + 91 +122 ---.
Step-by-step explanation:
to find the sum of nth term
equation is
n/2 ( 2a + (n-1)d) where a is the 1st term and d is the common difference
5/2 ( 120 +( 4 × 31))
5/2 ( 120 + 124)
5/2 × 244
5 × 122 dividing 244 by 2
610
Answer: 610
Step-by-step explanation:
This sequence starts at 60 and increases by increments of 31. Thus, to get the last two numbers, do 122+31=153, and 153+31=184. Then add 60+91+122+153+184 to get 610.

The height of the right circular cylinder is 10 cm and the radius of the base is 7 cm. Then, the difference between the total surface area and the curved surface area is a) 300 cm^2 b) 308 cm^3 c) 308 cm^2 d) 308 cm
plz answer it fast I will mark them as the brainlist
Answer:
The answer is option C
308cm²Step-by-step explanation:
Total surface area of a cylinder is
2πr( r + h)
The curved surface area of a cylinder is
2πrh
where r and h are the radius and height respectively
h = 10cm
r = 7cm
Total surface area is
2π×7( 7 + 10)
14π ( 7 + 10)
98π + 140π
238π
Which is
748 cm²
The curved surface area is
2π (7)(10)
140π
Which is
440cm²
The difference between the total surface area and the curved surface area of the cylinder is
748 cm² - 440cm²
= 308cm²Hope this helps you
