X²+y²-8x+12y+27=0
x²+y²-8x+12y=-27
x²-8x +y²+12y = -27
x²-8x+16 + y+12y+36 = -27+16+36=25
(x-4)² + (y+6)² = 25
a circle centered at (4,-6) with a radius of 5
Answer:
n = 1/2
Step-by-step explanation:
4/5(1/2) - 1/5 = 2/5(1/2)
4/10 - 2/10 = 2/10
Answer:
Step-by-step explanation:
The legs measuring 10 cm and 14 cm.
The height of the pyramid is 9 cm.
We need to find the volume of the pyramid. The formula for the volume of a right pyramid is given by :
Where
B is area of base,
Put all the values,
So, the volume of the right pyramid is equal to 
.
Answer:
5. x= 13 y= 18.4
6.
Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
same thing again but with tan30 ahaha
