Answer:
y - 5 =
(x - 1)
Step-by-step explanation:
Note that
= 
Differentiate using the power rule
(a
) = na
Given
y = x
= x.
=
, then
= 

When x = 1
=
. 1 = 
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m =
and (a, b) = (1, 5), thus
y - 5 =
(x - 1) ← equation of tangent

__________
Answer:
28
Step-by-step explanation:
32 - 9 = 23,
24 + 4 = 28
From the given problem, I gather that there are only two groups of forces. These are:
13 lb, 35 lb, resultant force 30 lb
20 lb, 15 lb, resultant force 25 lb
We use the pythagorean theorem to determine if the three forces are grouped correctly, such that the resultant force is the hypotenuse.
Resultant Force = √(a² + b²)
So, for the first group,
30 ? √(13² + 35²)
30 ≠ 37.33
Thus, the first group does not pull at right angles to each other.
For the second group,
25 ? √(20² + 15²)
25 = 25
Thus, the second group does pull at right angles to each other.
