My estimated answer for 1 is x=1.59 or x=-1.26 and my exact answer is (in word form) x= 1 plus or minus the square root of 73 over 6. my estimated answer for 2 is x=-0.34 or x=1.74 and my exact answer (in word form) is x= -7 plus or minus the square root of 109 over -10. I took a picture of my work and hopefully you can read it

Answer:
$2400
Step-by-step explanation:
The question is asking the amount invested in fund B. We can let 'b' represent that amount. Then the amount invested in fund A is (6000-b). The total profit from the investments is ...
0.02(6000 -b) +0.07(b) = 0.04(6000)
120 +0.05b = 240 . . . . . simplify
0.05b = 120 . . . . . . . . . subtract 120
b = 2400 . . . . . . . . . . .divide by 0.05
Alonzo invested $2400 in fund B.
Answer:
A because its supposed to be on the y axis
Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is 
.
So the side is 1.0 inch in, the surface area is 
square inches.
In Linear approximation means you ignore the term 
, if 
is a small number, because then will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here, 
The error in the area is approximately,
So the error is 0.012.
