Answer:
-6
Step-by-step explanation:
f(1)=-3
why because f(x)=y
so x=1
you go to the x-cordinate and u see where the y-cordinate is
-3
For the graph the answer is -3 for the exterior it's -6
Have a wonderful day/night ask me if you have more math questions
Brainliest Please.
64 degrees, you just divide the two numbers
Answer:
M=(4,112)=(4,5.5) A
Step-by-step explanation:
The midpoint for two points P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2).
We have that px=3, py=2, qx=5, qy=9.
Thus, M=(3+52,2+92)=(4,112).
Answer:
sample size at the beginning was 40 bacteria.
Step-by-step explanation:
Given that a sample of bacteria experienced 5% daily growth compounded continuously for 14 days
Let C be the initial amount of bacteria.
C grows continuously compounding at the rate of 5%
The equation representing the number of bacteria at time t days would be
![P(t) = Ce^{0.05t}](https://tex.z-dn.net/?f=P%28t%29%20%3D%20Ce%5E%7B0.05t%7D)
Now we have t = 14 days and P = 80.
Substitute to get
![80=Ce^{0.05(14)} \\C=80e^{-0.05(14)}\\C=39.72682](https://tex.z-dn.net/?f=80%3DCe%5E%7B0.05%2814%29%7D%20%5C%5CC%3D80e%5E%7B-0.05%2814%29%7D%5C%5CC%3D39.72682)
Approximately 40 bacteria were present at the beginning.
All solutions are infinite
Explanation: if you do this problem, -4(p+7) it’s -4p-28
And when you do -4p + -4p it equals 0, then -28=-28 that means your solutions are infinite
