Given horizontal axis length is larger than the vertical axis length, the standard form of an ellipse is:

[(x-h)/a]^2 + {(y-k)/b]^2 = 1

where (h,k) is center; a and b are the major and minor axis

(h,k) = (0,0) and a=18, b=2

(x/18)^2 + (y/2)^2 = 1 is the standard form equation

Ellipse center (0,0) so its eqn is x^2/a^2 + y^2/b^2 = 1
major axis is horizontal n length 18
so at y=0, x=+/-18
a=18
minor axis is vertical n length 2
so at x=0, y=+/-2
b=2

ans is (x/18)^2 + (y/2)^2 = 1

If angle 4 is 52.7, what are the measures of angles 1,2, and 3? ​
shusha [124]

Answer:

  1. 127.3
  2. 52.7
  3. 127.3
  4. 52.7

Step-by-step explanation:

Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).

52.7 + x = 180

x = 127.3

Best of Luck!

A cone and its dimensions are shown in the diagram. Which measurement is closest to the volume of the cone in cubic inches?
Diano4ka-milaya [45]
20 Cubic Inches^3.

Explanation:

The volume of a cone is Pi*R^2*H*1/3

We know the height, but we are given the diameter instead of radius. So divide 5.625 by 2. You get 2.8125.

Plug everything into the formula.

Pi*2.8125^2*7.5*1/3

(The ^2 means squared, or to the second power)

You get a number close to 20. Since we don’t know Pi, and we are not given a substitute for Pi, we make the answer in terms of Pi.

20 Cubic Inches^3.

Also, people who don’t know the answers to questions shouldn’t just put a random answer for the points. It’s unfair.

Which comparison is not correct?
strojnjashka [21]

Answer:

the 2 one is wrong

Step-by-step explanation:

the 2 would be greater than the 9 sense both the numbers are negative and the bigger the negative number is the less amount it is so -9 is smaller than -2
