Answer:
distance = sqrt( 65 ) ~= 8.06
Step-by-step explanation:
To find the distance between two points, we can use the distance formula.
distance = sqrt( [x2 - x1]^2 + [y2 - y1]^2)
distance = sqrt( [-5 - 2]^2 + [3 - -1]^2)
distance = sqrt( [-7]^2 + [4]^2)
distance = sqrt( 49 + 16 )
distance = sqrt( 65 ) ~= 8.06
Cheers.
Yes it is a rational number
Answer:
13cm
Step-by-step explanation:
Using Pythagoras theorem, we have
H^2 = 5^2 + 12^2
= 25 + 144
= square root of 169
= 13cm
A. The drop-out rate can be estimated using the equation,
d = my + b
where d is the drop-out rate, m is the slope of the line, y is the number of years from 1998 and b be the initial value. For 2008,
18.3 = m(2008 - 1998) + 38.46
The value of m from the equation is -1.12. The equation becomes,
d = -1.12y + 38.46
b. The vertical intercept of the model is when d is equal to zero.
0 = -1.12y + 38.46
The value of y from the equation is 34.34.
(34.34, 0)
c. n = 1990 + 34.34 = 2024.34.
The vertical intercept of this problem tells me that by the year 2024, the drop-out rate would be 0%.
