Answer:
2/3
Step-by-step explanation:
slope of a line is y1-y2/x1-y2 where you get two points. Here, you get the points (6,0) and (0,-4). When you plug the numbers in the equation you get
0+4/6-0, which simplifies to 4/6, and reduces to a slope of 2/3
Answer:
16
Step-by-step explanation:
Area of circle Formula: A = πr²
d = 2r
Simply plug in what you know:
201.0624 = 3.1416r²
64 = r²
r = 8
d = 2(8)
d = 16
Answer:
16
Step-by-step explanation:
f() = + 12
Plug as 4 and solve.
f(4) = 4 + 12
f(4) = 16
Answer:
e. None of the above is correct.
Step-by-step explanation:
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval
a = initial number of infected people
r = growth rate of infection
x= time taken in weeks
Hence;
5000= 10(1 + 1.78)^t
5000/10 = (1 + 1.78)^t
500 = (1 + 1.78)^t
log 500 = tlog(1 + 1.78)
t = log 500/log(1 + 1.78)
t = 2.699/0.444
t = 6 weeks
