Answer:
The focus of the ellipse are;
(-12·√(10), -8) and (12·√(10), -8)
Step-by-step explanation:
The given equation for the ellipse is presented as follows;
[tex]\dfrac{x^2}{46} + \dfrac{(y + 8)^2}{26} = 1[/tex]
From the general equation of the ellipse, we have;
[tex]\dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1[/tex]
The focus of the ellipse are, (h - c₁, k) and (h + c₁, k)
By comparison, we get;
h = 0, k = -8, a = 46, b = 26
We have;
c² = a² - b²
c² = 46² - 26² = 1440
c = 12·√(10)
The focus of the ellipse are therefore;
(0 - 12·√(10), -8) = (-12·√(10), -8), and (0 + 12·√(10), -8) = (12·√(10), -8).

17. A man stands 4300 feet from the Burj Khalifa in
Dubai (world's tallest building). The angle of
elevation from his eyes (5 feet) to the top of the
building is 32°. How tall is the building?
9514 1404 393
Answer:
b. 2692 ft
Step-by-step explanation:
The relation of interest between the sides of the right triangle is ...
Tan = Opposite/Adjacent
Using the given numbers, that is ...
tan(32°) = (building height)/(4300 ft)
Multiplying by 4300 ft, we get ...
building height = (4300 ft)·tan(32°) ≈ 2686.9 ft
This is the height above the observer's eyes, so the height of the building above the ground is ...
2687 +5 = 2692 . . . . feet
The building is 2692 feet tall.

Answer:
7(left answer), 3(top left answer), and 10(top right answer)
Step-by-step explanation:
So what are two things that go into 21?
21 and 17 and 3Out of those two, which is a factor of 70? Right off the bat we know 7 is.
THis isnt the greatest factor of 70, but it is for both 21 and 7, so now we know the left answer for hieght is 7.
Now 3 must be the top left answer, because you must make 21 with 7. 7 Goes into 21 3 times, so it has to be 3. So now we know that the top left anhswer is 3.
Finally we have our top right answer. We already know that the height is 7, now we need to find the width. All we have to do is divide 70 by the 7 heigh, and we will find our width:
70/7
=
10
So now we know that the top right answer is 10.
Sorry that you couldnt get a real answer from people, I hope this is in time to help!
Triangle ABC below has a right angle C and a hight CD. If AC is 3 units long and BC is 4 units long, what is the length of AB?
Answer:
AB = 5
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
=> 3² + 4² = AB²
=> AB = [tex]\sqrt{3^{2}+4^{2} }[/tex]
=> AB = 5
A water container in the shape of a cone has a height of 5 inches and a diameter of 3.5 inches.
Enter an equation in the first blank box and a number in the second blank box to complete the statements about the
water container ___.
A. The formula to calculate the container's volume, V, with the given measurements is
B. The container can hold approximately ___ cubic inches of water. Round your answer to the nearest hundreth.
Answer
A. The formula to calculate the container's volume, V, with the given measurements is ⅓ π(1.25²)5.
B. The container can hold approximately 8.177 cubic inches of water. Round your answer to the nearest hundredth.
Step-by-Step Explanation
A. The formula to calculate any cone's volume is ⅓ πr²h. Replace the variables with the actual values of the cone. r stands for the cone base's radius, or half of the diameter. Because the diameter is 3.5, the radius is 1.25, or half of it. The h stands for the height of the cone. Now we can plug in the values. Our answer for this part is ⅓ π(1.25²)5.
B. Now to solve our equation. [tex]1.25^2[/tex] is equal to 1.5625. Now, multiply by the height. 1.5625 x 5 is equal to 7.8125. We now multiply by [tex]\pi[/tex]. We'll use 3.14 to shorten the answer a bit. Multiply 7.8125 by 3.14 and you'll get 24.53125. Last but not least, divide this by 3 (or multiply by [tex]\frac{1}{3}[/tex]). [tex]\frac{24.53125}{3}[/tex] = 8.1770833333... We now must round this to the nearest hundredth. This makes our final answer 8.177 [tex]in^3[/tex].
In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
Explain how you found your answer.
Enter the correct answers in the boxes.
Answer:
150cm²
Step-by-step explanation:
In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
The formula for the area of a trapezoid = 1/2(a + b) h
Where a = Length of the first base
b = Length of the second base
h= height of the trapezoid
h = 10cm
The length of one base is equal to its height
Hence:
a = h = 10cm
The length of the other base is twice its height.
b = 2h
h = 10cm
b = 10 × 2 = 20cm
Therefore, the Area of the Trapezoid =
1/2 (20 + 10)10
1/2 × 30 × 10
= 150cm²
