Answer:
exponential function, cool
Step-by-step explanation:
looks like f(x) = e ^x
So f(3) would be e^(3)
you can work this out on your calculator.
press [2ndf] [e^x]] [3] = 20
Best thing is draw a line up from x-axis to the curve, where it hits the curve you will have your answer
Answer:
area of P=πr^2
area of Q=πr^2/4=π×400/4=100π
acc to ques
A(q)=4× A(p)
100π=4×πr^2.
100=4r^2
r^2=25
radius of p= √25=5cm
Answer:
Irrational
Step-by-step explanation:
42 is the number because...
42 ÷ 6 = 7
42 ÷ 7 = 6
Answer:
