The line goes 3 right for every 1 down, so the gradient is -1/3
The y-intercept is +4, so the equation is actually y=-1/3x+4, so Chris is wrong.
Answer: 7272
i got this by following the quadratic formula of b
here is your answer pls check the answer hope u can understand
Answer:
The equation sets the parabola. You can find the parabola vertex as:
then
This means that the maximum height is 11.375 m and a projectilereaches this height at 1.25 seconds.
The projectile initially launched at time t=0, so the initial height is h(0)=2 m
Step-by-step explanation:
Treat the c formula as a line. c = sm +b; where m= number of months.
using the two examples:
260 = 12s +b
380 = 18s + b
solve for s & b:
s = 20
b =20
So a 30-month membership is:
c = 20(30) + 20 = 600
Solve C for c and you get 600
