Answer:
(a) 0.5km or 500m
(b) 100m
Step-by-step explanation:
(a) 1 hour = 60 minutes
60 minutes = 30km
5 minutes = 30 ÷ 60
= 0.5km = 500m
(b) 1 minute = 500m ÷ 5
= 100m
the absolute value of the product of the zeros of a is 
.
<u>Step-by-step explanation:</u>
Here we have , 
is a polynomial function of t, where k is a constant. Given that a(2) = 0 . We need to find the absolute value of the product of the zeros of a . Let's find out:
Equation every factor of a(t) to zero we get:
⇒ 
⇒ 
⇒ 
But , t=2 So , 
. Now , the absolute value of the product of the zeros of a is :
⇒ 
⇒ 
⇒
Therefore, the absolute value of the product of the zeros of a is .
H=3.7
Then 0.8+h=0.8+3.7
=4.5
Im not sure wym but i think the answer is 20

Answer:
$3277.23
Step-by-step explanation:
The future value of the CD with interest at rate r compounded semiannually for t years will be given by ...
A = P(1 +r/2)^(2t)
where P is the principal value.
For the given rate and time, this is ...
A = $2000(1 +0.05/2)^(2·10) = $2000(1.025^20) ≈ $3277.23
The value of the CD at maturity will be $3277.23.
