Answer:
7,8,9
Step-by-step explanation:
The closest you can get to 42 with that equation and it has to use consecutive intergers is 41 and these numbers get you there.
Surface area of the pyramid= 4*(area of the triangle) + area of the square
Area of the triangle = (1/2)*base*height=(1/2)*5*5= 25/2 in²
Area of the square = 5*5 =25 in²
Surface area of the pyramid = 4*(25/2) + 25=2*25 + 25=75 in²
Answer:
AB= 8/Cosine 60 degrees
Step-by-step explanation:
Cosine=Adjacent/Hypotenuse
Cosine=8/AB
AB=8/Cosine 60 degrees
Answer:
Step-by-step explanation:
The standard equation of a parabola is
y² = 4ax
where, a is the focus,
The coordinates of the centre of parabola is (0,0)
coordinates of focus is (a, 0)
It is symmteric about the x axis
the equation of directrix is x = -a.
Answer:
A = 1/4
B = 3/4
step-by-step explanation:
the middle should be 1/2 because the middle between 0 and 1 is 1/2
A and B are both in the middle of the sides
therefore A would be closer to 0 so 1/4
and B would be closer to 1 so 3/4
