Answer:
chemical formula for silver sulfate Ag2SO4
Answer:
Attached
Step-by-step explanation:
Given the inequalities as
y>-2x+3
y<1/2x-2
Graph the inequalities on the graph tool
The solution is points in the shaded area such as (2,2),(4,4),(4,2),(2,-2),(2,-4)
The point (-2,3) is not included in the solution area because it is located in the un-shaded area.
Mathematically, taking points (-2,3) into the inequality
y>-2x+3
3>-2(-2) +3
3>4+3
3>7---------------------not correct because 3<7

Answer:
Ques 1: 7.85
Ques 2: both and are rational.
Ques 3: 0.9
Step-by-step explanation:
Ques 1:
Solving the , we get 7.8485.
Rounding off to nearest hundredth, we see that next digit is 8, so we increase the previous digit by 1.
So, the answer to nearest hundredth is 7.85.
Ques 2:
and to be checked whether they are rational or irrational.
We know that is equal to 4.
= -4 which is a rational value.
Let us solve now.
Which is a rational value.
So, both are rational.
Ques 3:
Simplify
0.81 can be written as in rational form.
Now, taking the square root, we need to take the square root for both Numerator and Denominator and then we can divide to get the desired square root.
So, the answers are:
Ques 1: 7.85
Ques 2: both and are rational.
Ques 3: 0.9
Answer:
The maximum value of P is 32
Step-by-step explanation:
we have following constraints
----> constraint A
----> constraint B
----> constraint C
----> constraint D
Solve the feasible region by graphing
using a graphing tool
The vertices of the feasible region are
(0,2),(0,8),(8,0),(2,0)
see the attached figure
To find out the maximum value of the objective function P, substitute the value of x and the value of y of each vertex of the feasible region in the objective function P and then compare the results
we have
so
For (0,2) --->
For (0,8) --->
For (8,0) --->
For (2,0) --->
therefore
The maximum value of P is 32
