Answer:
7.884
Step-by-step explanation:
so taking the point T(13,1.6) and the point V(5.4,3.7) we move from point T(13,1.6) to the point V(5.4,3.7) the x-coordinate increases by ( 13-5.4)=7.6 and the y- coordinate decreases by ( 1.6-3.7)=(-2.1). now we have 7.6 and -2.1. we find the squares of this numbers and add so we have 7.6 giving us 57.76 and -2.1 giving us 4.41. now we add both 57.76+4.41=62.17. and we find the square roots √62.17 which will give us 7.884. and therefore the distance between the two point is 7.884
Answer:
18
Step-by-step explanation:
Stella will have $160 saved after 6 months .
This is because, each month, Stella sets aside double the amount
Month 1 : $5
Month 2 : $10
Month 3 : $20
Month 4 : $40
Month 5 : $80
Month 6 : $160
Hope this is correct!
(-1,2)(2,-1)
slope = (-1 - 2) / (2 - (-1) = -3/3 = -1
y = mx + b
slope(m) = -1
use either of ur points...(-1,2)...x = -1 and y = 2
sub and find b, the y int
2 = -1(-1) + b
2 = 1 + b
2 - 1 = b
1 = b
so ur equation is : y = -x + 1 <==
A)
If it has an area of 4(x+3) we can think that one side has a length of 4, and the other has a length of (x+3).
So, if the dimensions were doubled, 4 x 2 = 8. And 2(x+3) = 2x+6.
The new area would be:
8(2x+6) = 16x+48.
B)
The ratio will be the same. For example lets plug in some points:
x=0
4(0+3) = 4(3) = 12
And
16(0)+48 = 0+48 = 48
So the ratio is 48/12 = 4
Lets plug in another point.
x=2
4(2+3)= 4(5) = 20
And
x=2
16(2)+48 = 32 + 48 = 80
80/20 = 4
So the ratio is the same :)
