Answer:
Area of ellipse is ≈ 77.78
Step-by-step explanation:
Given the dimension of ellipse
a = 4.5 m
b = 5.5 m
Now, Area of ellipse =
=
=
= 77.78
Hence Area of ellipse will be 77.78
Answer:
y = - 9 and x = 7
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (7, - 9) with y- coordinate - 9 , then
y = - 9 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (7, - 9) with x- coordinate 7 , then
x = 7 ← equation of vertical line
Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
A pair of supplementary angles are C and E. We know that B, D, and E are all congruent, and can see that both C and B, and C and D would form supplementary angles. So, we can also use E to form supplementary angles.

Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
