Hello,
xy=2 is the cartesian form.
Indeed:
x=r cos t ==>cos t=x/r
y=r sin t ==> sin t=y/r
r²*sin 2t=4 ==>r²*2 sin t cos t=4
==>r²*x/r*y/r=2==>xy=2
Answer:
and
Step-by-step explanation:
According to the figure, x is part of a complementary angle and y is from a supplementary angle:
Answer:
1. -13 degrees
2. $12
3. 6 yards
4. 15 points
Step-by-step explanation:
1. -5 - 8 = -13
2. $100 - $88 = $12
3. 13 - 7 = 6
4. 10 x 2 = 20 - 5 = 15
Volume can be expressed as the product of the area and the height. The allowable volume given would be 260 cm^3. The volumes of the hexagonal prism and the triangular prism should sum up to this value or lesser to enable Josie in making the candles she wants.
Volume of the hexagonal prism = 21 x 8 = 168 cm^2
Volume of the triangular prism = 14 x 7 = 98 cm^2
Adding up the calculated volumes,
168 + 98 = 266 cm^3
Therefore, the triangular prism cannot have a base area of 7 cm^2.
