Answer: 59,500
Step-by-step explanation:
Given
For 10,000 residents, 17,000 police officers are hired
The ratio of Police officers and citizens is constant
So, for 35,000 citizens suppose x officers are hired

Thus, 59,500 officers are required.
You can use two negative numbers and add them to get -6. An example can be -4+-2=-6
Answer:

Step-by-step explanation:
Given the indefinite integral
, using the substitute
x = 4 sec(θ)...1
The integral can be calculated as thus;
First let us diffrentiate the substitute function with respect to θ
dx/dθ = 4secθtanθ
dx = 4secθtanθdθ... 2
Substituting equation 1 and 2 into the integral function we will have;

Find the remaining solution in the attachment.
If certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. The amount it cost to run this refrigerator for one year if the cost per kWh is $0.11 is: $53.856.
<h3>Cost</h3>
Given:
Electricity watts = 170 watts
Minutes run = 20 minutes
Cost per KWh =$0.11
Hence,
170 watts = 1.7×10^-1
20 min = 1/3 h
Now let calculate the cost of running the refrigerator for one year
1.7×10^-1 × 1/3 × 24 ×360 × $0.11
= $53.856
Therefore If certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. The amount it cost to run this refrigerator for one year if the cost per kWh is $0.11 is: $53.856.
