Answer:
- P = -390t +48,000
- P = 43,710 in 2003
Step-by-step explanation:
A) We are given two pairs of (t, P): (0, 48000), (8, 44880). We can use these with the 2-point form of the equation of a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (44880 -48000)/(8 -0)(t -0) +48000
P = -3120/8t +48000
P = -390t +48000
__
B) In 2003, t = 11, so we have ...
P = -390(11) +48000 = 43710
The population in 2003 is predicted to be 43,710.
Answer:
i would say for the second one 2.5 and the first one about 30
Step-by-step explanation:
Answer:
A. 36*
Step-by-step explanation:
first find angle a:
180-117=63
a=63
then find angle b by subtracting 81 and 63 from 180
180-81=99
99-63=36
angle b = 36
The answer is B maybe try it?
The solution for this equation is x= <-5
