5 11

Expert Solution & Answer
Check Mark
To determine

To calculate: The value of the expression, 511.

Answer to Problem 1DE

Solution:

The required value of the expression 511 is 6_.

Explanation of Solution

Given information:

The provided expression is 511.

Formula used:

For any real numbers a and b, add the opposite of the number to subtract it from the number as below:

ab=a+(b)

Further use the rules of addition as below to simplify.

Step 1. To add the positive numbers, add the numbers and the result is positive.

Step 2. To add negative numbers, add the absolute values and make the answer negative.

Step 3. The numbers with same absolute value and opposite signs add up to 0.

Step 4. If the numbers are of different absolute values, subtract the smaller value from the larger value and put the sign of the value with greater absolute value to the answer.

Step 5. If one number is zero, then its sum with a number is the number other than zero.

Calculation:

Consider the provided expression that is

511

Add the opposite of the numbers to subtract it and simplify as below,

511=5+(11)

Add by the rules of addition as,

5+(11)=6

Hence, the subtraction of the expression 511 is 6.

On Feb. 8, this year, at 6am in the morning all UiB meteorology professors met to discuss a highly unfortunate and top-urgent crisis: Their most precious instrument, responsible for measuring the air temperature hour-by- hour, had failed - what if the Bergen public would find out? How would they plan their weekend without up-to-date air temperature readings? Silent devastation - and maybe a hint of panic, also - hung in the room. Apprentice Taylor, who - as always - was late to the meeting, sensed that this was his chance to shine! Could they fake the data? At least for some hours (until the measurements would work again)? He used to spend a lot of time online and thus knew the value of fake data, especially when it spread fast! He reminded the crying professors of a prehistoric project with the title "Love your derivatives as you love yourself!" - back then, they had installed top-modern technology that not only measured the air temperature itself, but also its 1st, 2nd, 3rd, 4th, and…
Consider a forest where the population of a particular plant species grows exponentially. In a real-world scenario, we often deal with systems where the analytical function describing the phenomenon is not available. In such cases, numerical methods come in handy. For the sake of this task, however, you are provided with an analytical function so that you can compare the results of the numerical methods to some ground truth. The population P(t) of the plants at time t (in years) is given by the equation: P(t) = 200 0.03 t You are tasked with estimating the rate of change of the plant population at t = 5 years using numerical differentiation methods. First, compute the value of P'(t) at t = 5 analytically. Then, estimate P'(t) at t = 5 years using the following numerical differentiation methods: ⚫ forward difference method (2nd-order accurate) 3 ⚫ backward difference method (2nd-order accurate) ⚫ central difference method (2nd-order accurate) Use h = 0.5 as the step size and round all…
Nicole organized a new corporation. The corporation began business on April 1 of year 1. She made the following expenditures associated with getting the corporation started: Expense Date Amount Attorney fees for articles of incorporation February 10 $ 40,500 March 1-March 30 wages March 30 6,550 March 1-March 30 rent Stock issuance costs March 30 2,850 April 1-May 30 wages Note: Leave no answer blank. Enter zero if applicable. April 1 May 30 24,000 16,375 c. What amount can the corporation deduct as amortization expense for the organizational expenditures and for the start-up costs for year 1 [not including the amount determined in part (b)]? Note: Round intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. Start-up costs amortized Organizational expenditures amortized
