Answer:
Step-by-step explanation:
calculate the difference height (P) is -6 and (t) is 2.85
Δy divided by Δx = rate of change
3-9 = -6
6.23-3.41 = 2.85
then divide
2.85 / -6 = .475
Your answer will be - .475
Ok so first we need to turn
to a decimal like so...
Divide top to bottom so 9/10 divide by 5
so now we have 0.18
SO there's your answer 0.18
Answer:
1/9
Step-by-step explanation:
a - b = 2
27^(1/3b)/9^(1/2a)
so...b = a - 2
27^( (1/3) b ) / 9^((1/2) a )
= (3^3)(1/3b) over (3^2)^(1/2a)
= 3^b over 3^a = 3^ (b - a) = 3^(-2) = 1/9
--------------
9^(1/2b)/3^a = (9^(1/2))^b / 3^a = 3^b / 3^a = 3^(b -a) = 3^-2 = 1/9
a. years since 1990 (t) = 30
enrollment: n = -0.3|30 - 8|+11 = -0.3*22 + 11 = 4.4, which means 4400 students
b. Replacing into the equation with n = 10, we get:
10 = -0.3|t - 8|+11
10 - 11 = -0.3|t - 8|
(-1)/(-0.3) = |t - 8|
10/3 = |t - 8|
t - 8 = 10/3 or t - 8 = -10/3
t = 10/3 + 8 t = -10/3 + 8
t = 11 1/3 t = 4 2/3
t = 11 1/3 corresponds to year 1990 + 11 = 2001
t = 4 2/3 corresponds to year 1990 + 4 = 1994
