Mathematics

You could rewrite this expression as (-1)^3*5^3.

Note that (-1)^3 = -1 and that 5^3 = 5*5*5 = 125.

So the answer is -125.

Can someone help me? I know 1 is 90 and 5 is 90 but idk the rest
miv72 [106K]

Answer:

2 is 60 degrees, 5 is 90 degrees, 4 is 20 degrees, 3 is 30 degrees, and 1 is 90 degrees.

Step-by-step explanation:

All angles have to equal up to 90 degrees. Some you can guess, but others you might have to think about. So just look at the lines and you will see four boxes or four sections. Each have to equal up to 90 degrees, so that's what you get for those. It's kinda hard to explain, but I hope this helps, have a good day. c;

a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equat
Sergio [31]

We have been given that a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation y=35795(0.83)^x, where x represents the number of years since purchase and y represents the value (in dollars) of the car.

To find the value of car of after 5 years, we will substitute x=5 in our given equation as:

y=35795(0.83)^5

y=35795\cdot (0.3939040643)

y=14099.79598

Upon rounding to nearest tenth, we will get:

y\approx 14099.8

Therefore, the car will be worth $14,099.8 after 5 years it is first purchased.

Since $14,099.8 is less than original value of car, therefore, we know hat value of car is depreciating and $14,099.8 is correct answer.

We also know that an exponential decay function is in form y=a(1-r)^x, where,

y = Final value after t years,

a = Initial value,

r = Decay rate in decimal form,

x= Time.

17\%=\frac{17}{100}=0.17

y=35795(1-0.17)^x

y=35795(0.83)^x
