If Sadie earns $11.25 per hour, her earnings will vary directly with the number of hours that she has worked per week.

If she made $146.25 in a work week, she worked 13 hours.

13 hours x 11.25 = 146.25

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What mul
Alex_Xolod [135]

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.

1.

\left[\begin{array}{ccc}-30 & -5 \\ 20 & 30 \\ -35  & 35 \end{array}\right]    +   \left[\begin{array}{ccc} 20 & -4 \\ -12 & -32 \\ 24 & 32 \end{array}\right]     =  \left[\begin{array}{ccc} -10 & -9 \\ -8 & -2 \\ -11 & 67 \end{array}\right]

A cyclist rides her bike at a rate of 5 meters per second. What is this rate in kilometers per hour ? How many kilometers will t
Romashka-Z-Leto [24]

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

By what factor must you multiply a number in order to triple its square root?
LiRa [457]
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
