The graph below shows the number of new clients brought into Sunnydays Insurance Company. Why is the graph misleading?

Lera25 [3.4K]

The graph is misleading because the year’s interval is not constant. The first year to the second year, the gap is 1 year; in the second to the third year, the gap is 2; in the third to the fourth year is 4; and the fourth to the fifth year is 6.

Point A is located at (-2, 2), and point M is located at (1,0). If point M is the midpoint of AB, find the location of point B.

bezimeni [28]

Answer:

B. $B = (4,-2)$

Step-by-step explanation:

GIven that $A = (-2, 2)$ and $M = (1, 0)$ , and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:

$M = \frac{1}{2}\cdot A + \frac{1}{2}\cdot B$

The location of B is now determined after algebraic handling:

$\frac{1}{2}\cdot B = M - \frac{1}{2}\cdot A$

$B = 2\cdot M -A$

Then:

$B = 2\cdot (1,0)-(-2,2)$

$B = (2\cdot 1, 2\cdot 0)-(-2,2)$

$B = (2,0) -(-2,2)$

$B = (4,-2)$

Which corresponds to option B.

On a map of a park three inches represents twenty feet. how manyinches would represent 12 feet.

creativ13 [48]

$\bf \begin{array}{ccll} \stackrel{map}{inches}&\stackrel{actual}{feet}\\ \cline{1-2} 3&20\\ x&12 \end{array}\implies \cfrac{3}{x}=\cfrac{20}{12}\implies \cfrac{3\cdot 12}{20}=x\implies \cfrac{9}{5}=x\implies 1\frac{4}{5}=x$
