Describe the error in finding the distance between $A(6,\ 2)$ and $B(1,-4)$ . Student work marked wrong shows the steps in a calculation. First line. A B equals left-parentheses 6 minus 1 right-parentheses squared plus left bracket 2 minus left-parentheses negative 4 right-parentheses right bracket to the second power. Second line. Equals 5 squared plus 6 squared. Third line. Equals 25 plus 36. Fourth line. Equals 61.

Did not use a ruler.

Did not find the midpoint.

Did not take the square root.

Did not make all the signs positive.
Question 2
The actual length, $AB$ , rounded to the nearest tenth is
units.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

the answer

b. they are parallel and will never intersect.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
