how many solutions does the quadratic have? 2x^2+3x-5
Answers
Answer:
2 solutions
Step-by-step explanation:
Given
2x² + 3x - 5 ( to solve the quadratic equate it to zero )
2x² + 3x - 5 = 0 ← in standard form
(2x + 5)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]
x - 1 = 0 ⇒ x = 1
The 2 solutions are x = - [tex]\frac{5}{2}[/tex] , x = 1

About 9/10 Of the avocados grown in the United States are in California about what percent of our car is going in the United States are grown in California?
Answers
Answer:
9/10 x 100% = 90%
Step-by-step explanation:
The question is asking us to convert the given fraction, 9/10, to percentage. As we know, to convert any number to percentage, we simply multiple by 100%. We are not changing the value because 100% means 100/100 = 1. So, we are basically multiplying by 1.
Since we are told that 9/10 avocados grown in the US are grown in California, then the percentage would be:
9/10 x 100% = 90%

A company which uses the revaluation model for its PPE bought a building on 1 January 2014 for £50m. The building has an estimated useful life of 50 years and nil residual value. On 31 December 2018, the building was revalued at £40.5m and on 31 December 2020 it was revalued for a second time at £39m. The company uses the straight-line method of depreciation for all PPE items. There was no change to the remaining useful life after each revaluation. What is the net effect of both revaluations on the statement of comprehensive income?
Answers
Answer:
The net effect of both revaluations on the statement of comprehensive income is a net revaluation loss of £4.20m that will reduce the comprehensive income by the exact amount of £4.20m.
Step-by-step explanation:
This can be determined using the following 3 steps:
Step 1: Calculation of the effect of first revaluation: from 01 January 2014 to 31 December 2018
Building cost = £50
Number of useful life = 50
Revalued amount on 31 December 2018 = £40.5m
Annual depreciation expenses from 01 January 2014 to 31 December 2018 = Building cost / Number of useful life = £50m / 50 = £1m
Number of years from 01 January 2014 to 31 December 2018 = 5
Total depreciation expenses from 01 January 2014 to 31 December 2018 = Annual depreciation expenses from 01 January 2014 to 31 December 2018 * Number of years from 01 January 2014 to 31 December 2018 = £1m * 5 = £5m
Net book value on 31 December 2018 = Building cost - Total depreciation expenses from 01 January 2014 to 31 December 2018 = £50m - £5m = £45m
Revaluation loss from the first revaluation = Net book value on 31 December 2018 - Revalued amount on 31 December 2018 = £45m - £40.5m = £4.50m
Step 2: Calculation of the effect of second revaluation: from 01 January 2019 to 31 December 2020
Revalued amount on 31 December 2020 = £39m
Number of useful life remaining after 31 December 2018 = Number of useful life - Number of years from 01 January 2014 to 31 December 2018 = 50 - 5 = 45
Annual depreciation expenses from 01 January 2019 to 31 December 2020 = Revalued amount on 31 December 2018 / Number of useful life remaining after 31 December 2018 = £40.5m / 5 = £0.90
Number of years from 01 January 2019 to 31 December 2020 = 2
Total depreciation expenses from 01 January 2019 to 31 December 2020 = Annual depreciation expenses from 01 January 2019 to 31 December 2020 * Number of years from 01 January 2019 to 31 December 2020 = £0.90 * 2 = £1.80
Net book value on 31 December 2020 = Revalued amount on 31 December 2018 - Total depreciation expenses from 01 January 2019 to 31 December 2020 = £40.5m - £1.80 = £38.70m
Revaluation surplus from the second revaluation = Revalued amount on 31 December 2020 – Net book value on 31 December 2020 = £39m - £38.70 = £0.30m
Step 3: Calculation of the net effect of both revaluations on the statement of comprehensive income
Net revaluation loss = Revaluation loss from the first revaluation - Revaluation surplus from the second revaluation = £4.50m - £0.30m = £4.20m
Therefore, the net effect of both revaluations on the statement of comprehensive income is a net revaluation loss of £4.20m that will reduce the comprehensive income by the exact amount of £4.20m.
The net effect of the revaluations on December 31, 2018 and December 31, 2020 is that the comprehensive income will reduce by £11 million.
Data and Calculations:
Cost of PPE on January 1, 2014 = £50 million
December 31, 2018:
Revaluation amount = £40.5 million
Revaluation Loss = £9.5 million (£50 million - £40.5 million)
New book value = £40.5 million
December 31, 2020:
Revaluation amount = £39 million
Revaluation Loss = £1.5 million (£40.5 million - £39 million)
New book value = £39 million
Total Revaluation Loss = £11 million (£9.5 + £1.5 million)
Thus, the net effect of both revaluations on the company's statement of comprehensive income is reduction of £11 million.

There is a word problem and idk how to do it here's the word problem [Kari is making copies at a local store of the program for her school play she makes 52 copies and the total is $6.24. How much did the store charge her per copy] this is in math
Answers
Answer:
Unitary cost per copy= $0.12
Step-by-step explanation:
Giving the following information:
Total number of copies= 52 copies
Total cost= $6.24
We need to calculate the unitary cost of each copy. To do that, we will use the following formula:
Unitary cost per copy= total cost / number of copies
Unitary cost per copy= 6.24/52
Unitary cost per copy= $0.12

Step-by-step explanation:
Since we have the present grater than the original, then the change is increasing
Secondly, we want to calculate the percent of change
Mathematically , that will be ;
(present - original)/original * 100%

Pedro has a student loan of $62,845. This loan has a simple interest rate of 7% per year. What is the amount of interest that Pedro will be charged on this loan at the end of the year?
Answers
P=62,845
R=0.07 or 7%
T=1 year period
So overall your equation is 62845*0.07*1=$4,399.15
Now at this point the interest is added onto the principal amount to figure out some new amount after one year so:
62845.00+4399.15=$67,244.15

Which of the following is the most reasonable domain and range for the function?
Answers
Answer:A
Step-by-step explanation:A
The most reasonable domain and range for the function is x≥0, y≥0. Therefore, option B is the correct answer.
The given function is f(x) = 3000 + 100x.
We need to find which of the following is the most reasonable domain and range for the function.
What is the domain and range of the function?The domain and range are defined for a relationship and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (-∞, ∞) {x|x∈R}
Range: (-∞, ∞) {y|y∈R}
The most reasonable domain and range for the function is x≥0, y≥0. Therefore, option B is the correct answer.
