To find the midpoint of line FG, we have to use the following midpoint formula , which is

(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})

In the given question,

x1= -5, y1= -3 , x2=-3, y2=3

Substituting the values of x1,y1,x2 and y2 in the formula of the midpoint, we will get

(\frac{-5-3}{2},\frac{-3+3}{2})  =(-4,0)

So the midpoint of the given line is (-4,0) and hence the correct option is the first option .

Alchen [17]

Answer:

Constant of proportionality is 12

The cost of buying new bicycle changes  12 dollar per week

Step-by-step explanation:

we are given

The equation as

d=12w

where

d represents the amount in dollars

w is number of weeks

now, we can compare it with

y=kx

where

k is constant of proportionality

we can compare

and we get

k=12

So,

Constant of proportionality is 12

we can see that

12=\frac{d}{w}

So,

The cost of buying new bicycle changes  12 dollar per week

❅☃ To find a function you need to look at the x values, if one of the same x value is repeated more then once, it is considered a non function.
❅☃ Option A:
-14
-9
-1
4
6
As you can see no repeated values.
Therefore A is already our function but lets look at the others just in case. 
❅☃ Option B
-2
1
9
9
15
9 was repeated therefore it is a non function.
❅☃ Option C
-4
6
6
7
9
6 was again repeated. Non function.
❅☃ And lastly, D.
-16
-11

Steven wishes to save for his retirement by depositing $2,000 at the beginning of each year for thirty years. Exactly one year a
Ad libitum [116K]

Step-by-step explanation:

i = interest 3% for 30 years

This is a simple dynamical system for whom the the solutions are given as

S=R[\frac{(i+1)^n-1}{i}](i+1)

putting values we get

S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)

= $98005.35

withdrawal of money takes place from one year after last payment

To determine the result we use the present value formula of an annuity date

P = R\frac{1-(1+i)^{-n}}{i}{i+1}

we need to calculate R so putting the values and solving for R we get

R= $6542.2356
