Stacie is choosing between two careers. Working for company A, Stacie will make $45,000 the first year and will receive an addit

fomenos

The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is

$S=\frac{n}{2}(2a +(n-1)d)$

Where a is the first term, n is the nth term, d is the common difference

On substituting there values,we will get

$S =\frac{30}{2}(2*42000+(30-1)1800)$

= 15(84000+52200) = 15*136200 =2043000

And for company A, it is

$S= \frac{30}{2}(2*45000+(30-1)1500 ) = 15(90000+43500)=2002500$

Difference between them =2043000-2002500= 40500

So the correct option is the second option .

Find BC if B(8,-7) and C1-4,-2).

Alika [10]

Using distance formula :

$\sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} }$

$\sqrt{(8 - ( - 4)) {}^{2} + ( - 7 - ( - 2)) {}^{2} }$

$\sqrt{(12) {}^{2} + ( - 5) {}^{2} }$

$\sqrt{144 + 25}$

$\sqrt{169}$
