Cos x = adj/hyp
Cos F = 6/10 = 3/5
Answer: 3/5
Answer:
see explanation
Step-by-step explanation:
A column vector has the form ![\left[\begin{array}{ccc}x\\y\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Following the direction of the arrow , the x- displacement = - 3 and y- displacement = 2 , then column vector is
![\left[\begin{array}{ccc}-3\\2\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%5C%5C2%5C%5C%5Cend%7Barray%7D%5Cright%5D)
h + k
=
+
← add corresponding elements from each vector
= ![\left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4-2%5C%5C-3-1%5C%5C%5Cend%7Barray%7D%5Cright%5D)
= ![\left[\begin{array}{ccc}2\\-4\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%5C%5C-4%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Answer:
34% = 272 students
100% = 272/34%
= 800 students
Step-by-step explanation:
to check whether the answer is correct
= 34% × 800
= 272 students
Y = 13.
Explanation
Replacing the value x with 4 in the function gives that y= 4+9
y= 13
