Answer:
300
Step-by-step explanation:
I think its 300 but if I'm wrong then XD I Don't know
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is

By following the formula, cos=3/5 then:

Multiply everything (inside the square

root) by 5


Then just simplify

The answer is Square root of 20 over 5
Answer:
Cost to buy and run the first car for 5 years=$24000
Cost to buy and run the second car for 5 years=$26000
I think we should buy the first car, because It is cheaper to buy and maintain
Step-by-step explanation:
first car:
Cost $18000 to buy
Cost $100 to maintain each month
5years =5 x 12=60months
Cost to maintain for 60months=100x60=$6000
First car cost to buy and run over the 5 year period=18000+6000=$24000
Second car:
It cost $22400 to buy
Cost $60 to maintain each month
5years=60months
Cost to maintain for 60months is 60 x 60=$3600
Cost to buy and run over the second car for 5years is 22400+3600=$26000
Answer:
The rate at which the account pay the deposit is 2 %
Step-by-step explanation:
Given as :
The principal amount deposited in account = $2100
The rate of interest = r % simple interest annually
The time period = 11 months =
year
The amount received = $2138.50
Now<u>, From Simple Interest method </u>
Simple Interest = 
Or, Interest = 
Or, Interest = 
Or, Interest = 19.25 r
Now, Interest = Amount - Principal
So, 19.25 r = $2138.50 - $2100
Or, 19.25 r = $38.5
∴ r = 
I.e r = 2
So, rate of interest = r = 2 %
Hence The rate at which the account pay the deposit is 2 % Answer
Can you be more specific pls
