Answer:
0.98
Step-by-step explanation:
Explanation
The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.
In this case the first term = 10000
The second term = 98% × 10000 = 9800.
The common ratio = 9800/10000=49/50
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.
The equation of the exponential rate would be;
10,000ₓ0.98ⁿ.
where n is the number years.

Step-by-step explanation:
This is a matrices. Since they are both the same in format, we can add them together. But first we must multiply each value by the given values.

Answer:
18 km/hr
90 km
Step-by-step explanation:
We know that there are
1000 m = 1 km
and
3600 s = 1 hr
We need to convert m/s to km/h
5 m 3600s 1 km 18000km 18 km
------ * ------------ * ------------ = --------------- = ------------
s 1 hr 1000m 1000 hr hr
It is 18 km/hr since the units cancel.
We want to know how far the cyclist travels
d=rt
We know the rate 18km/hr and the time = 5 hr
d = 18 km/hr * 5 hr
d =90 km
To solve the problem shown above you must apply the following proccedure:
1. Let's call:
x: a number.
f: the factor.
2. Then, you have:
√fx=3√x
3. You must clear the factor "f" to calculate its value, as below:
√fx=3√x
(√fx)²=(3√x)²
fx=9x
f=9x/x
4. Then, the factor is:
f=9
5. Therefore, b<span>y what factor must you multiply a number in order to triple its square root?
