Answer:
answer : A
Step-by-step explanation:
hello :
Sin 42°= Cos(90°-42°)=cos(48°)......answer : A
Add ten from both sides and then divide 40 of 5x its 8
B subtract 8 from both sides 13 divide by 3 answer is 13/3
Answer:
- <em> 15</em>
- <em> 42,250</em>
Step-by-step explanation:
The given function is,

where,
P = the total production of apples,
x = the number of trees added.
As the quadratic function has a negative leading coefficient, so it will open downward and at the vertex the value of function is maximum.
The vertex will be at 
The value of the function will be maximum at,

Putting the values,

So at x=15 or for 15 number of trees the production will be ,maximum.
Putting x=15 in f(x) will yield the maximum production of apples.

Answer:
x=2
Step-by-step explanation:
6x+11-4x=15
2x+11=15
2x=4
x=2
