I'm not sure but at least i tried
Answer:
17.
Step-by-step explanation:
Statement: "ten more than the product of two and a number"
Translation: 10 + (2 * x)
x = 3.5
10 + (2 * 3.5)
= 10 + 7
= 17.
Hope this helps!
If you’re trying to find f(-1) it would be -20
Answer:
384 square cm
Step-by-step explanation:
Fabric used will be equal to the total surface of the cubical block.
What we have so far:
Kinetic energy = 0. The reason behind that is because the beam is not moving at a height of 40m.
Gavity, g = 9.8m/s²
Height = 40m
Potential energy = mgh; this is equal to 0 because m, stands for mass and in this problem, we do not have a value for the mass of the beam. Hence, 0 x 9.8m/s² x 40m = 0. Potential energy = 0.
Solution:
We will use the equation of Total energy:
TE = potential energy + kinetic energy
TE = 0 + 0
∴ TE = 0
The answer is: Assuming no air resistance, the total energy of the beam as it hits the ground is 0.
