Answer:
Correct option: third one -> 11.5 m3
Step-by-step explanation:
To find the volume of the ramp, first we need to find the volume of the rectangular prism and the volume of the triangular prism:
V_rectangular = 4m * 2m * 1m = 8 m3
V_triangular = (2m * 3.5m * 1m) / 2 = 3.5 m3
Now, to find the volume of the ramp, we just need to sum both volumes:
V_total = V_rectangular + V_triangular = 8 + 3.5 = 11.5 m3
Correct option: third one.
The equation correctly modeled would be
1000+.02t = 15000
Answer is -28.37
Step-by-step explanation:
from the numerator cos 2a×cos 3a - cos 2a×cos7a= cos6a^2 -cos 14a^2
= -cos8a^2 for the numerator
from the denominator;
sin4a×sin3a-sin2a×sin5a= sin12a^2 -sin10a^2
= sin2a^2
therefore, combining the equation it gives; -cos8a^2/sin2a^2
a^2 will divide each other,
= -cos8/sin2.
from the calculator,
= - 0.9903/0.0349
= -28.37
