From what I imagine in the problem description, the toy is located on the ground. Then, Belkis is pulling on the string to keep the toy moving just like how you put a leash on a dog. My illustration is shown in the picture. The F arrow is where Belkis pulls it. Its component vectors are Fx and Fy, as shown.
From the figure, we can see that it forms a right triangle. So, it makes it easy because the pythagorean theorems are applicable and we can easily use trigonometric functions. First, let's determine Fy which is located opposite to the angle. Since we know the hypotenuse F to be 1.5 N, so we use the sine function:
sin 52° = Fy/F = Fy/1.5
Fy = 1.182 NFor the horizontal component, Fx is parallel to the adjacent side with respect to the angle. Thus, we use the cosine function.
cos 52° = Fx/F = Fx/1.5
Fx = 0.923 N
You have to guess the first 5 digits.
You can calcualte the number of possible numbers that exist with 5 digits.
The first digit cannot be 0, it can be any from 1 to 9, so those are 9 diferent digits.
For the second, third, fourth and fifth digits there are 10 diferent posibilities for each: 0 through 9.
Then, there are 9*10*10*10*10 = 90,000 different possible social security numbers once the last four digits are known.
And the probability to get the correct social security number of the person is 1 /90,000 = 0,000011.
Answer:
6(1/4) or 25/4 (25 divided into 4 = 6.25
Step-by-step explanation:
0.25 =1/4
6 and 0.25 = 6(1/4)
If we convert in improper fraction is 25/4
Answer:
56 ways
Step-by-step explanation:
Number of ways is given by n combination r (n!/(n - r)!r!)
n = total number of students = 8, r = the number of summer courses = 3
Number of ways = 8 combination 3 = 8!/(8-3)!3! = 8!/5!3! = 8×7×6×5!/5!×6 = 8×7 = 56 ways
