Answer:
Step-by-step explanation:
radius=4 as it is tangent to x-axis.
y co-ordinate of center is 4 so radius=4
eq. of circle is (x-2)²+(y-4)²=4²
or x²-4x+4+y²-8y+16=16
or x²+y²-4x-8y+4=0
Answer:
700$
Step-by-step explanation:
If all the seats cost tge same and each member takes a seat each game so we can say:
7×4=28
5×4=20
28x+20x=1200
48x=1200
x=25(seat price)
28×25=700
20×25=500
Answer:
15
Step-by-step explanation:
n + 6
for
n = 9
then:
9 + 6 = 15
Answer:
D
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 0.5h(a + b)
where h is the perpendicular height and a, b the parallel sides.
Given A = 120, then
0.5 × 8(a + b) = 120, that is
4(a + b) = 120 ( divide both sides by 4 )
a + b = 30 cm → D
