From a hot-air balloon, Eli measures a 38° angle of depression to a landmark that's
1922 feet away, measuring horizontally. What's the balloon's vertical distance above
the ground? Round your answer to the nearest hundredth of a foot if necessary.
Answers
Answer:
1,501.47 ft
Step-by-step explanation:
the vertical distance above the ground =
1922 × tan 38° = 1,922 × 0.7812
= 1,501.47 ft
Answer:
1501.63ft is required answer m

Graph BChoice C) y = 0.13x - 0.19===========================================
Explanations:
Notice how all of the points in graph B are near to a single line. This is the regression line. We don't have every point on the same line, but it's close enough. Graph A seems to suggest an exponential growth curve could work as the regression curve. Graph C seems to be randomly scattered points, so perhaps no function would work as the regression curve.I used technology to get the regression line. Specifically, I used GeoGebra. Any spreadsheet program or graphing calculator should be able to find the regression line. You can do so by hand, but I don't recommend it because it's tedious busy work in my opinion.The diameter of a wheel of a car is 77 cm. How many revolutions will it make to cover 242 m? (Take π≈22/ 7)
Answers
This value is approximate because pi = 22/7 is approximate.
===========================================================
Explanation:
Let's find the perimeter of the wheel, aka the circumference
C = pi*d
C = (22/7)*77
C = 242
The distance around the tire is approximately 242 cm
At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.
We can say the following
1 meter = 100 cm
242 meters = 24200 cm .... multiply both sides by 242
One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.
1 revolution = 242 cm
100 revolutions = 24200 cm ... multiply both sides by 100
---------------------------
We could also use a proportion to solve
(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)
1/242 = x/24200
1*24200 = 242x
242x = 24200
x = 24200/242
x = 100

Answer:
The correct answer is "16.987, 20213".
Step-by-step explanation:
Given that,
[tex]n=30[/tex]
[tex]\bar x=18.6[/tex]
[tex]s = 5.2[/tex]
[tex]df=30-1[/tex]
[tex]=29[/tex]

By using the table, the critical values of t will be:
= [tex]\pm 1.699[/tex]
Now,
The confidence interval will be:
= [tex]\bar x \pm \frac{t\times s}{\sqrt{n} }[/tex]
By putting the values, we get

B. 6^6
Step-by-step explanation:
the fraction can be flipped to get rid of the negative exponents. this leaves you with 6^8/6^6 which is equal to 6^2. if you multiply that by 6^4 you can add the exponent values together. So you get 6^6
Answer:
6^6 (Six to the power of six)
Step-by-step explanation:
Step one: Since you are using the power over a power rule, when it comes to dividing an exponent, it gets subtracted by the one below, so that results in 6^2
Step 2: Another power rule is that when you are multiplying exponents, you are actually adding exponents, so it would end up being 6^6

Step-by-step explanation:
Since 33=30 and 0.1081 is supposed to be as a percentage since its already a decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number.

Answers
Answer:
[tex](x-1)^2+(y-6)^2=16[/tex]
Step-by-step explanation:
The equation of a circle is given by [tex](x-h)^2+(y-k)^2=r^2[/tex], where [tex](h,k)[/tex] is the center of the circle and [tex]r[/tex] is the radius of the circle.
From the diagram, we can find the following:
the radius of the circle is 4 the center of the circle is located at (1,6)Thus, we have:
[tex](x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}[/tex]
Answer:
(x-1)^2 + (y-6)^2 = 16
Step-by-step explanation:
center = (1,6)
radius = 4
equation of a circle (x-h)^2+(y-k)^2=r^2
(x-1)^2 + (y-6)^2 = 16
