60 POINTS AND WILL MARK BRAINLIEST Given the points A(-1,2) and B(7,14), find the coordinates of the Point P on the directed line segment AB that partitions AB in the ratio 1:3. In the above problem, what is the value of a/(a+b)?

.

The line APB is a line such that AP/PB= 1/3. From the points A and B that we have we can find the distance between those points using the formula d= [(y2-y1)^2=(x2-x1)^2]^1/2

d= 4 (13)^(1/2)

Now the ratio is 1:3. AP= sq rt(13) and PB= 3 sq rt(13)

Using mid point formula the mid point of AB (say Q) = [(-1+7)/2,(2+14)/2]= (3,8).  

Hence the mid point of AQ is P which can found out again using the mid point formula  

P= [(-1+3)/2,(2+8)/2]= (1,5)

Final P=(1,5)

Step-by-step explanation:

I got the same thing as the first person. I honestly have no idea I'm soo sorry! I'm failing my grade as of now and i need to ask some questions thank you so much.

Step-by-step explanation:

I literally got banned 2 days ago and had tons of points but now i have -229 points thank you so much have a great day

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

im with everythinglos so yeahhhhh
