Answer:
3.2
Step-by-step explanation:
3.21428571429 is the exact answer and rounded to the nearest tenth is the first number after the decimal.
The system of 5x + 2y ≤ 25 is given by 20x + 15y ≤ 120 and 5x + 2y ≤ 25
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the cucumber and y represent the amount of carrots, hence:
20x + 15y = 2(60)
20x + 15y ≤ 120 (1)
Also:
5x + 2y ≤ 25 (2)
The system of 5x + 2y ≤ 25 is given by 20x + 15y ≤ 120 and 5x + 2y ≤ 25

Given data
<span>sin (x+pi/2)=cos x
</span>now using sin law
sin(a+b)=sin(a)cos(b)+cos(a)sin(b)
now using above values
sin(pi/2+x)=sin(pi/2)cos(x)+cos(pi/2)sin(x)
as we know that
sin(pi/2)=1
cos(pi/2)=0
now putting these values
sin(pi/2+x)=1*cosx+0*1
sin(pi/2+x)=cosx
hence proved that
<span>sin (x+pi/2)=cos x</span>
