A point on the top of the Leaning Tower of Pisa is shifted about 13.5 ft horizontally compared to the tower's base. To the nearest degree, how many degrees does the tower tilt from vertical?
Without the exact height of the Leaning Tower of Pisa, we cannot find the specific degree of tilt. However, given the height is approximately 183.27 ft, we can use the tangent function to roughly find that the tilt is near 4.22 degrees.
Explanation:The question involves the concept of trigonometry, specifically the tangent function, to calculate the angle of tilt of the Leaning Tower of Pisa. Assuming the tower forms a right triangle with the ground, we can utilize tangent, which is the ratio of the opposite side (the horizontal shift) to the adjacent side (the height of the tower) to determine the angle of tilt. Thus, the angle of tilt θ is calculated as θ = tan⁻¹(13.5/height). Unfortunately, without the exact height of the tower, we cannot give a specific degree of tilt.
However, the actual height of the tower is roughly 183.27 ft. Substituting that value into the equation gives θ = tan⁻¹(13.5/183.27), which approximates to around 4.22 degrees when calculated.

Using trigonometry and taking into account the horizontal shift and height of the Leaning Tower of Pisa, we found that it tilts around 4 degrees from vertical. The procedure entails determining the tangent of the tilt angle and using the arctan function to calculate the angle in degrees.
The problem involves finding the tilt angle of the Leaning Tower of Pisa given its horizontal displacement. We will consider the height of the tower, which is approximately 55 meters (about 180.45 feet).
We can use trigonometry, specifically the tangent function, tan(θ) = opposite/adjacent, to find the angle of tilt. Here, the 'opposite' side is the horizontal shift (13.5 feet) and the 'adjacent' side is the height of the tower (180.45 feet).
Identify the opposite and adjacent sides:
Horizontal shift (opposite) = 13.5 feetHeight of the tower (adjacent) = 180.45 feetUse the tan function to find the angle:
tan(θ) = opposite / adjacent = 13.5 / 180.45Calculate the tangent value:
tan(θ) ≈ 0.0748Find the angle θ using the arctan function:
θ = arctan(0.0748) ≈ 4.28 degreesRound to the nearest degree:
θ ≈ 4 degreesTherefore, the Leaning Tower of Pisa tilts approximately 4 degrees from vertical.

A catapult launches a boulder with an upward velocity of 120 ft/s. The height of the boulder, h,
in feet after t seconds is given by the function h=-167 + 120t + 10. How long does it take to
reach maximum height? What is the boulder's maximum height? Round to the nearest
hundredth, if necessary.
a. Reaches a maximum height of 235.00 feet in 3.75 seconds.
b. Reaches a maximum height of 10.00 feet in 7.50 seconds.
c. Reaches a maximum height of 7.58 feet in 3.75 seconds.
d. Reaches a maximum height of 15.16 feet in 7.5 seconds.
Answer:
Reaches a maximum height of 235.00 feet in 3.75 seconds.
Step-by-step explanation:
The height of the boulder, h, in feet after t seconds is given by the function is given by :
[tex]h=-16t^2+120t+10[/tex] .....(1)
For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
i.e.
[tex]\dfrac{d(-16t^2+120t+10)}{dt}=0\\\\-32t+120=0\\\\32t=120\\\\t=3.75\ s[/tex]
Put t = 3.75 in equation (1). So,
[tex]h=-16(3.75)^2+120(3.75)+10\\\\h=235\ \text{feet}[/tex]
So, the boulder's maximum height is 235 feets and it takes 3.75 s to reach to its maximum height.
a concrete pillar has the shape of a cylinder. it has a diameter of 6 meters and a height of 7 meters. concrete cost $116 per cubic meter how much did the concrete cost for the pillar
Answer:
The cost of the pillar is $22,947.12
Step-by-step explanation:
Diameter of the pillar = 6m
Radius = diameter / 2 = 6 / 2 = 3m
Height if the pillar = 7m
Volume of the pillar = πr²h
π = 3.14
V = 3.14 × 3² × 7
V = 3.14 × 9 × 7
V = 197.82m³
Volume of the pillar is 197.82m³
If 1m³ = $116
197.82m³ will cost $x
X = (197.82 × 116) / 1
X = $22,947.12
The cost of the pillar is $22,947.12

Which of the following shows extraneous solutions to the logarithmic equation? (See picture)
Answer:
Option 3
Step-by-step explanation:
log4(x) + log4(x - 3) = log4(-7x + 21)
log4(x² - 3x) = log4(-7x + 21)
x² - 3x = -7x + 21
x² + 4x - 21 = 0
x² + 7x - 3x - 21 = 0
x(x + 7) - 3(x + 7) =0
(x + 7)(x - 3) = 0
x = -7, 3
-7 and 3, both are e extraneous solutions because logs of non-positive numbers don't exist
At x = 3,
-7x + 21 = 0
the radius of a circle is 5 inches what is the area of a sector biunded by 180 degrees arc
The area of a sector with a radius of 5 inches and a 180-degree arc is half the area of the full circle, resulting in 39.27 square inches when rounded.
Explanation:The area of a sector of a circle with radius 5 inches that is bounded by a 180-degree arc can be found by first calculating the area of the entire circle and then taking half of that area, since 180 degrees is half of the full 360 degrees of a circle. The formula to calculate the area of a circle is A = πr². For a radius (r) of 5 inches, the entire circle's area would be A = π(5 inches)².
Thus, the entire circle area is A = 3.1415927 × (5 inches)² = 78.53981633974483 square inches. Since the sector is half of the circle, the area of the sector would be 39.269908169872415 square inches, or when rounded to two decimal places, 39.27 square inches.

Sam volunteers at an animal shelter. He created a line plot to show the weights in pounds of the kittens at the
shelter
Weights of Kittens in Shelter
Pounds
What is the total weight of the kittens in the shelter? Enter your answer in the box
pounds
Answer:
5 pounds
Step-by-step explanation:
The line plot shows that we have 3 kittens with 1/2 pounds, 2 kittens with 1 pound and 1 kitten with 1 1/2 pound.
So, to find the total weight of the kittens in the shelter, we can multiply the number of kittens by their weights, and then sum then all:
Total weight = 3 * (1/2) + 2 * 1 + 1 * (1 + 1/2)
Total weight = 3/2 + 2 + 3/2 = (3 + 4 + 3)/2 = 10/2 = 5 pounds

x =(7+√-3)/2=(7+i√ 3 )/2= 3.5000+0.8660i
Step-by-step explanation:
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-7x+13
The first term is, x2 its coefficient is 1 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is +13
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is -7 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14
13 + 1 = 14
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Equation at the end of step 1 :
x2 - 7x + 13 = 0

Brian invests £1300 into his bank account.
He receives 10% per year simple interest.
How much will Brian have after 3 years?
Give your answer to the nearest penny where appropriate.
Answer:
£1690
Step-by-step explanation:
Amount invested by Brian = £1300
rate of simple interest = 10%
To find money Brian will have after three years
He will have amount invested in bank and interest earned in three years from that amount.
Simple interest for any principal amount p is given by
SI = P*R * T /100
where SI is simple interest earned
T is time period for which simple interest is earned
R is rate of interest
Substituting value of P , R and T we have
SI = 1300*10* 3 /100 = 390
Therefor interest earned will be £390
Total money with Brian after three years = principal amount invested + interest earned in 3 years
= £1300 + £390 = £1690

Answer:
(a)1/3
(b)2/3
Step-by-step explanation:
This is a 6-sided number cube, therefore total possible outcomes, n(S)=6
(a)Probability of rolling a 2 OR 3 =P(2)+P(3)
[tex]=\dfrac{1}{6} +\dfrac{1}{6} =\dfrac{2}{6}\\= \dfrac{1}{3}[/tex]
(b)Probability of not rolling a 2 OR 3
In probability, the sum of the probability of an event and its complement is always 1.
Therefore:
P(Rolling a 2 or 3)+P(Not rolling a 2 or 3)=1
From part (a) above:
Probability of rolling a 2 OR 3=[tex]\dfrac{1}{3}[/tex]
Therefore:
[tex]\dfrac{1}{3}+$P(Not rolling a 2 or 3)=1\\P(Not rolling a 2 or 3)=1-\dfrac{1}{3}=\dfrac{2}{3}[/tex]

Show how to find the inverse of f(x) = x^3 - 5. Calculate 3 points on f(x) and use these points to show that the inverse is correct.
Answer:
[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]
Step-by-step explanation:
A function [tex]f^{-1}[/tex] is the inverse of f if whenever y =f(x) and [tex]x =f^{-1}[/tex]
To find the inverse of f(x) = [tex]x^{3}[/tex] - 5, we use the following steps:
Step 1 : Put y for f(x) and solve for xy = [tex]x^{3}[/tex] - 5
<=> [tex]x^{3}[/tex] = y + 5
<=> x = [tex]\sqrt[3]{y+ 5}[/tex]
Step 2: Put [tex]f^{-1}(y)[/tex] for x, we have:[tex]f^{-1}(y) =\sqrt[3]{y+5}[/tex]
Step 3: Interchange y =x, we have[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]
Let Calculate 3 points on f(x)
x = 0 => y = -5
x = 1 => y = -4
x = 2 => y = 3
Let Calculate 3 points on [tex]f^{-1}[/tex] (x)
x = -5 => y = 0
x = -4 => y = 1
x = 3 => y = 2
