Answer:
a
Step-by-step explanation:
We are looking for an exponential function 
where r is less than 1.
a works because it is in the form where r is less than 1.
b is in the form but r is more than 1.
c. and d. are not even exponential functions.
c. is a polynomial
d. is a constant polynomial (no variable)
Cotx can also be written as cosx/sinx. So sinx × cosx/sinx = cosx.
Answer:
7kg
Step-by-step explanation:
6kg=24N, ?kg=28N
28.x= 24.6
28x= 168
x=168:24
x= 7kg
Answer:
10.5
Step-by-step explanation:
Answer:
B 6 x^2 sqrt(3)
Step-by-step explanation:
sqrt(6x^2) sqrt(18x^2)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(6x^2*18x^2)
sqrt(108x^4)
sqrt(36 *3*x^4)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(36)sqrt(x^4)sqrt(3)
6 x^2 sqrt(3)
