_____
1.7 | 45.78
ok....we want to make the 1.7 into a whole number....we do this by moving the decimal 1 space to the right.....and since we move the decimal one space on the divisor, we need to move the decimal 1 space on the dividend.
so ur problem would now be :
______
17 | 457.8
Hello :
a reasonable domain for this function is : <span>]0
; + ∞[<span>
because : x </span></span>> 0 and x+4 > 0 .... f(x) = x(x+4) ... length ×<span>width</span>
Answer:
Step-by-step explanation:
Natsano can satisfy his constraints by investing the first $20,000 in Company A, then splitting the remaining $35,000 evenly between the companies. For best return, he needs to invest as much as possible in Company B, but each such dollar (after the first 20k) must be matched by a dollar invested in Company A. That is, his investments should be ...
- Company A: $37,500
- Company B: $17,500
_____
The attached graph shows the feasible region of investments (doubly shaded). The vertex that maximizes the objective function (return on investment) is the one highlighted. (It puts the objective function line as far as possible from the origin.)
_____
Sometimes graphing the constraints is more work than necessary if there is some simple logic that quickly identifies the solution.
Given:
total = 750
ratio = 7 : 8
We need to get the ratio of the number to its total
7 + 8 = 15 ; 7/15 and 8/15 is the ratio of the number to its total.
We multiply these ratio to the total of 750
7/15 * 750 = 350
8/15 * 750 = 400
7:8 is equal to 350:400
Answer:
B) 216 and 330
or
C) 216 and 343
Well, for starters, I will pick B) 216 and 330 as my answer because its closer than C) 216 and 343, even though both can be the answer.
