Answer:
42°, 101°
Step-by-step explanation:
These answers come from the angle subtraction postulate.
Answer:
They need an additional 54 inches of fabric
Step-by-step explanation:
This can be solved by using the unitary method.
Unitary method is that we find the measure of 1 unit and then mulitply it with the required number to get the actual measurement.
4 yards of fabric is equal to 144 inches
1 yard of fabric is equal to 144 inches/4= 36 inches
They need an additional 1 1/2 yards of fabric
So multiplying 1 1/2*36= 3/2*36= 3*36/2= 108/2= 54 inches
They need an additional 54 inches of fabric
E=0.5mv^2
That's the formula for kenetic energy. The only unknown we don't have is the velocity. In perticular the final velocity. To find this final velocity we need to use kinematic equations. Since we have the time and I'm also assuming that the initial velocity was zero we're going to use Vf=Vi+at. The acceleration is 9.8m/s^2 because its free fall and we have the time 22s. Vf= 9.8*22=215.6m/s
Now that we have the final velocity plug it in to the kenetic energy formula.
=0.5*3*215.6^2= 69725.04J
Answer:
If you mean factoring then 2(8-t)
Other than factoring I can't think of what you could mean by 16-2t
