Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
Just divide both sides by 2 because you want to do the opposite operation, to isolate x so if you do you get 80 so x = 80
Answer:
Put this table into Desmos and then wherever the line crosses the y-axis, is your y-intercept.
Multiply
(x+a)(x+b) = x^2 + bx + ax + ab
looking at; x^2 + 10x + 24
can you see that
ab = 24
bx + ax = 10x
then
a + b = 10
use substitution: a = 10 - b
(10-b)b = 24
10b - b^2 = 24
-b^2 + 10b -24 = 0
now find the values for b using the quadratic equation. I'm on my phone so you'll have to plug the numbers in. let me know if you have any questions.
Answer:
8377
Step-by-step explanation:
Growth rate is exponential, so it is determined by the formula (1+growth rate)^n where n is years
1.035^15 = 1.675...
multiply by 5000, you get 8376.744....
