Answer:
35 degrees
Step-by-step explanation:
Answer:
√2
Step-by-step explanation:
Angle ( θ ) = 45
Hypotenuse side = 2
Opposite side = x
Formula : -
sin θ = Opposite side / Hypotenuse side
Note :
The value of sin 45 = 1/√2
sin 45 = x/2
1/√2 = x/2
Cross multiply,
x*√2 = 2*1
x√2 = 2
2 can be simplified as √2 * √2
x√2 = √2*√2
Divide √2 on both sides,
x = √2
Might be wrong haven't done algebra for years but i think it is 7-9n/7
Answer:
(a) 21
(b)2520
Step-by-step explanation:
(a)
Using combination formula, nCr where n is the total sample and r is the limitation hence 7 combination 5.
[tex}7C5=\frac {7*6*5*4*3}{5*4*3*2*1}=\frac {2520}{120}=21[/tex]
(b)
If the scholarships are not equal
The number of ways to select the 5 students from 7 we use permutation formula hence
7P5 = 7*6*5*4*3 = 2520
Up, you add the number to the given equation; down, you subtract. To change the steepness, multiply x by the factor involved.
A) y = 3x -10
B) y = (1/2)x +4
C) y = x -1
