(b) She should have rounded –8.02 to –8
Step-by-step explanation:
Given
See attachment for long division
Required
Her error
Ignoring the minus sign,
Her approximation is as follows:
Her approximation of -8.02 is wrong
Because:
<em>Hence (b) is correct</em>
Hi there! Your answer to the problem would be Store A..
Step By Step Explainaction:
So we know that store A’s boxes cost $6 for each 3 boxes, and store be cost 5$ for 2 boxes.
Divide 6 with 3 since you want to know how much one would cost. 6 divide 3=6. Let check again by doing multiplication. 3x2 is also 6. This means that the cost for each box for Store A would be 2$.
Store B is the same but dividing 5$ with 2. 2x2=4 but we need to know 5. But 1 is actually .5 or 50% of 2. So it would be 2.5 or 2 and a remainder of 1. Same things...
So it would be Store A that gives cheaper cost. $2>$2.5
F(x)= 5(-x^3)-3+2
f(x)=5(-x^3)-1
No because the lines or so called number are not particularly the same
