Answer:
5 - 3 times c is the correct ans
Answer:
A. The weight of the objects inside the box
Step-by-step explanation:
The energy required to lift a box is a function of the weight of it and of the distance it is lifted.
_____
In physics terms, the energy is the product of force and distance. The applicable force when lifting the box is the weight of the box (the box itself and any objects inside).
Answer:
C
Step-by-step explanation:
We require to find DC
ΔDEC and ΔBAC are similar triangles, hence the ratios of corresponding sides are equal, that is
= 
, that is
= 
( cross- multiply )
23.5DC = 506 ( divide both sides by 23.5 )
DC ≈ 21.532
distance travelled = BC + DC = 44 + 21.532 ≈ 65.5 in → C
Here, we are required to find the first term of an arithmetic progression which has a second term of 96 and a fourth term of 54.
- The first term of the progression which has a <em>second term</em> of 96 and a <em>fourth term</em> of 54 is; a = 117.
<em>In Arithmetic progression, the N(th) term of the progression is given by the formular;</em>
T(n) = a + (n-1)d
where;
Therefore, from the question above;
- T(2nd) = a + d = 96..............eqn(1)
- and T(4th) = a + 3d = 54..........eqn(2)
By solving the system of equations simultaneously;
we subtract eqn. 2 from 1, then we have;
<em>-2d = 42</em>
Therefore, d = -21.
However, the question requests that we find the first term of the progression; From eqn. (1);
a + d = 96
Therefore,
Ultimately, the first term of the progression is therefore; a = 117
