Answer:
25
Step-by-step explanation:
x = (20/28) * 35
x = 25
P = kq/r
5 = k*1/2
k = 2*5 = 10
p = 5*10/50 = 1
P is 1.

Factor out it by 2.
2(b² - 13b + 40) = 0
b<span>²</span> - 13b + 40 =0
This equation can be solved using the quadratic formula. If you know what a quadratic formula is, then you can get the two values for b. For instance,
(b - 8)(b - 5) = 0
Separate the two "roots", you will get:
b - 8 = 0
b = 8
and
b - 5 = 0
b = 5
Therefore the two values of b are 8 and 5.
Answer:
27.7 cm
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side in a right triangle to the hypotenuse. Here, that means ...
cos(30°) = y/(32 cm)
y = cos(30°)·(32 cm) ≈ 0.866·(32 cm)
y ≈ 27.7 cm
