Answer:

3, 8, 14, 30, 58

Step-by-step explanation:

As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.

$a_1=3\qquad\text{given}\\\\a_2=8\qquad\text{given}\\\\a_3=2a_1+a_2=2(3)+8=14\\\\a_4=2a_2+a_3=2(8)+14=30\\\\a_5=2a_3+a_4=2(14)+30=58$

The first 5 terms of the sequence are 3, 8, 14, 30, 58.

Point A is located at (3,6). The midpoint of line segment AB is point C(11,13). What are the coordinates of point B? Use the mid

lesya692 [45]

Answer: The coordinates of point B are (19 , 20).

Step-by-step explanation:

The mid point (x,y) of line joining (a,b) and (c,d) is given by :-

$(x,y)=(\dfrac{a+c}{2},\dfrac{b+d}{2})$ (1)

Given : Point A is located at (3,6). The midpoint of line segment AB is point C(11,13).

Let the coordinates of point B are (a,b) m, the according to (1) , we have

$(\dfrac{3+a}{2},\dfrac{6+b}{2})=(11,13)\\\\\Rightarrow\ \dfrac{3+a}{2}=11\ \ ,\ \ \dfrac{6+b}{2}=13\\\\\Rightarrow\ 3+a=22\ \ ,\ \ \ 6+b=26\\\\\Rightarrow\ a=19,\ \ b= 20$

Hence, the coordinates of point B are (19 , 20).

what is the difference between the weekly pay for the head mechanic and an assistant mechanic,if they both work 40 hour a week.

lora16 [44]

I am assuming you mean $37.52 per hour for the mechanic and $30.42 per hour for the assistant.
Simply multiply each of the hourly wages by 40 and compare the results by finding the difference.

Here:
$37.52 x 40 = $1500.80
$30.42 x 40 = $ 1216.80 When you subtract them you get $284 difference.
