Answer:
C
Step-by-step explanation:
Hello,
x=R*cos(t)
y=R*sin(t)
y=2x+1
==> Rsin(t)=2Rcos(t)+1
==>R(sin(t)-2cos(t))=1
==>R=1/(sin(t)-2cos(t))
Answer:
The second option, 1,008 cm²
Step-by-step explanation:
This shape has 5 sides to solve for with reguards to surface area.
Let us solve for them all.
[1 & 2 - the triangles]
12 * 9 = 108 cm²
-> I am not going to divide since we have 2 congruent triangles
[3 - the bottom side]
25 * 12 = 300 cm²
[4 - the side facing away]
25 * 9 = 225 cm²
[5 - the side facing up]
25 * 15 = 375 cm²
Now we will add them together for the total.
108 + 300 + 225 + 375 = 1,008 cm²
The surface area for the triangular prism shown is 1,008 cm².
5 * 10 raise to power of - 4
