Find the zeros of the quadratic equation y=4(x+9)²-36

Answer:

y=-2/5x

Step-by-step explanation:

The slope-intercept form of a linear function is y = mx +b, where m is the slope and b is the y-intercept.

Currently, 2x + 5y = 0 is in standard form and we can convert it to slope intercept form by simply isolating y (put the equation in terms of y):

The equation to calculate the balance in the account after "x" months would be: y = 100 + 25x

And after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

Step-by-step explanation:

Let's call the balance in Alexa's retirement account after "x" months "y".

The equation to calculate the balance in the account after "x" months would be:

y = 100 + 25x

After 6 months, Alexa would have added 6 * $25 = $150 to the original balance of $100, so the balance would be:

y = 100 + 25 * 6 = 100 + 150 = $250

After 12 months, Alexa would have added 12 * $25 = $300 to the original balance of $100, so the balance would be:

y = 100 + 25 * 12 = 100 + 300 = $400

So, after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

Answer:

C. Monthly

Step-by-step explanation:

If a business uses a monthly accounting period, it would prepare a post-closing trial balance once a month, at the end of the accounting period. Therefore, the correct answer is option C, monthly.

A post-closing trial balance is a list of all the accounts and their balances after adjusting entries have been made and closing entries have been posted to the general ledger. It is used to verify that the debits and credits are equal and that all temporary accounts have been closed out. The post-closing trial balance is prepared after the closing entries have been made at the end of the accounting period. For a business that uses a monthly accounting period, this would typically be done once a month, at the end of each month.

we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.

To compare the probabilities of acceptance of a shipment containing 20% defectives for the two rules, we can calculate the probabilities for both rules and compare the results.

For Rule 1, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 defectives in a sample of 10 components. This can be calculated as

P(Accept | 20% defectives) = (0.8)¹⁰

= 0.107374

For Rule 2, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 or 1 defectives in a sample of 20 components. This can be calculated as:

P(Accept | 20% defectives) = (0.8)²⁰ + ²⁰C₁ * (0.8)¹⁹ * (0.2)

= 0.276

Comparing the two probabilities, we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.

Answer:

120-x

Step-by-step explanation:

For me in class there were 6 parts to this problem and this problem is the same in my class so I will add all the answers

So for how many grams of 25% syrup it will be 120-x because the some amount + x = 120 grams of 15% syrup

so 120-x = the some amount of syrup.

This will be the answer for the problem you were asking for

If you have 6 parts keep scrolling since I will supply some more answers

Next part: How much pure sugar is in the 25% syrup?

For the amount of pure sugar there is in the 25% syrup

that will equal 0.25(120-x) = 30-0.25x

Next: How much sugar is in 120 grams of 15% sugar syrup?

10% of 120 is 12

5% = 12/2 = 6

12+6 = 18

Now the earlier stuff from the problem will come in handy

use the previous answers to write an equation

0.25(120-x)+0.10x=18

= 30-0.25x+0.10x=18

30 -0.15x=18

Now the final part to solve the equation and find the 10% solution and the 25% solution

-0.15x=18-30 = -12

-0.15x=-12

x= -12/-0.15

x=80

the problems not done yet though

we need to find the 25% solution

25% solution = 120-x and x = 80

120-80 = 40

The 10% solution is 80 grams and the 25% solution is 40 grams

The area of the shaded portion of the given figure is 84 sq. units.

What is meant by area?

The size of a region on a surface is determined by its area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a structure or planar lamina.

From the figure, we can conclude that,

Area of the shaded portion = Area of the square - Area of the four congruent parallelograms.

Now we have to find the area of square and parallelograms separately.

Area of square

Side length l = 12

Area = l *l = 12 * 12 = 144 sq. units

Area of parallelograms

Base b = 5

Height h = 3

Area of 1 parallelogram = b.h = 5 * 3 = 15 sq. units

Since all the parallelograms are congruent,

Area of all 4 parallelograms = 15 * 4 = 60 sq. units

Hence the area of the shaded portion of the given figure = 144 - 60

                                                                                          = 84 sq. units

Step-by-step explanation:

Answer: Let's call the number of pages printed "x". After printing x pages, the total cost for the Hewlett-Packard printer will be:

$200 + $0.03 * x

And the total cost for the Brother printer will be:

$240 + $0.01 * x

We want to find the number of pages "x" such that the cost of the two printers is the same, i.e., when:

$200 + $0.03 * x = $240 + $0.01 * x

We can isolate x by subtracting $240 from both sides and subtracting $0.01 * x from both sides:

$200 - $240 + $0.03 * x - $0.01 * x = 0

$-40 + $0.02 * x = 0

$0.02 * x = 40

x = 2000

So, the number of pages that need to be printed for the cost of the two printers to be the same is 2000 pages.

Answer:

∠ B = 23°

Step-by-step explanation:

vertical angles are congruent , then

∠ B = ∠ A , that is

5x - 17 = x + 15 ( subtract x from both sides )

4x - 17 = 15 ( add 17 to both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Then

∠ B = 5x - 17 = 5(8) - 17 = 40 - 17 = 23°

The equation of a line perpendicular to line y = 1/5x-2 in slope-intercept form that contains point (-3, 1) is y = -5x - 14.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

From the information provided, an equation of the first line WX is given by;

y = x/5 - 2

Therefore, slope (m) = 1/5

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

1/5 × m₂ = -1

m₂ = -5.

At point (-3, 1), an equation of the line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1 = -5(x - (-3))

y - 1 = -5(x + 3)

y = -5x - 15 + 1

y = -5x - 14

The balance account is prepared in accordance with the provided statement, and both the liabilities and assets total 2800000.

A balance sheet provides you with a quick overview of ones company's financial standing at any particular moment. A balance sheet, along with a revenue statement as well as a cash-flow statement, can aid business leaders in assessing the financial health of their organisation.

Computation of Current assets and Current Liabilities

Current Ratio  (CR) = Current Assets (CA)/ Current Liabilities (CL)  = 2.5

So, CA= 2.5 CL

Current Assets (C.A) - Current Liabilities (C.L) now equals Rs. 60000 as working capital.

Therefore, CA - CL = 60000 0

     2.5 CL-CL = 600000

     1.5 CL = 600000

        CL = 600000/1.5

     C.L = Rs.40000 0

C.A. now equals 2.5 x 400000, or Rs. 1000,000.

Computation of stock

Liquid ratio   = Liquid  assets/Current  liabilities

Or, 1.5 = (Current Assets - Stock )/400000

Or, 1.5  = (10,00, 000 - Stock)/4,00,000

1.5 *400000 = 1000000-Stock

600000 = 1000000- Stock

Therefore, stock = 100000-600000 = 400000

Computation of Proprietary fund; Fixed assets; Capital and Sundry payables (creditors)

Proprietors Fund divided by Permanent Assets equals Proprietors Fund.

Permanent assets therefore equal 0.75 proprietary fund, and

Net working capital  =  0.25 Proprietary fund

Therefore Proprietary fund = 600000/0.25

Proprietary fund = 24,00,0000 and  Fixed assets = 0.75 proprietary fund

= 0.75 of  24,00,000

Therefore, Fixed Assets = 18,00,000

Equity Capital = Proprietary fund - Reserves & Surplus

Therefore, Equity Capital = 2400000-400000

Equity Capital = 20,00,000

Variable payables (creditors) = (Current liabilities - Bank overdraft)

= (400000 - 100000) = 300000

Sundry payables = 300000

Net Current Assets =  (Current Assets - Stock) = 1000000-400000 = 600000

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

In particular, historical data shows that 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $20 .

p = price

n = number of shirts

m = slope of the line   (note, the more shirts, the lower the price, so we know it's going to be negative)

b = y intercept

so, the slope is

= (20- 30)/ (3000 - 1000)
