Answer:
(x-1)²/49 + (y+3)²/16.51 = 1
Step-by-step explanation:
vertex (8,-3) Foci (6.7,-3) center (h,k) = (1,-3) , major axis parallel to x axis
a is the distance of the vertex from the center, and c is the distance of the foci from the center. b is semi-minor axis
b² = a² - c² Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1
a = 8-1 = 7 c = 6.7 - 1 = 5.7
b² = 7² - 5.7² = 16.51
Ellipse equation: (x-1)²/49 + (y- -3)²/16.51 = 1 i.e. (x-1)²/49 + (y+3)²/16.51 = 1
So you have to put them in order: 22 38 44 59 70 79 85 87 96. The median is 70 so that means that Q2 is 70
Answer:
C
Step-by-step explanation:
y(x) = x^(1/3)+7
y(-8)=(-8)^(1/3)+7=5
y(-1)=(-1)^(1/3)+7=6
y(1)=(1)^(1/3)+7=8
y(8)=(8)^(1/3)+7=9
Answer:
perimeter = 44.05 yd
area = 164.25 yd^2
Step-by-step explanation:
The figure is shaped like a trapezoid with a semicircle.
Perimeter:
We add the lengths of the three sides of the trapezoid and the circumference of the semicircle.
perimeter = 15 + 11.2 + 10 + 0.5 * 3.14 * 5
perimeter = 44.05 yd
Area:
We find the area of the trapezoid and add to it the area of the half circle.
area = 0.5(10)(10 + 15) + 0.5(3.14)(5^2)
area = 164.25 yd^2
