An airplane is flying at an altitude of 33,000 feet. It needs to reduce its altitude by 6% to avoid some turbulence. After it pa

Tema [17]

Step-by-step explanation:

100% = 33,000 ft

1% = 100%/100 = 33000/100 = 330 ft

6% = 1% × 6 = 330 × 6 = 1980 ft

that means the plane has to go down 1980 ft to

33,000 - 1980 = 31,020 ft

and then it goes up by 5000 ft :

31,020 + 5000 = 36,020 ft

that is the final altitude.

Find the equation of the following ellipse based on the following information: Vertices: (-2,0), (2,0) minor axis of length 2

Sav [38]

Answer:

The expression of the ellipse is: $\frac{x^2}{4} + y^2 = 1$

Step-by-step explanation:

The equation of a ellipse can be written by the following expression:

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:

$2b = 2\\b = 1$

The length of the major axis is the distance between the two vertices.

$2a = \sqrt{[2 - (-2)]^2}\\2a = \sqrt{(2 + 2)^2}\\2a = \sqrt{4^2}\\2a = 4\\a = 2$

Therefore the expression of the ellipse is:

$\frac{x^2}{2^2} + \frac{y^2}{1^2} = 1\\\\\frac{x^2}{4} + y^2 = 1$
