Assume that t varies jointly as r and q2². If t=320 when r=5 and q = 4, what is the value of q when r= 1 and t= 196?
Harrizon [31]

Step-by-step explanation:

t = k(r)( {q}^{2} )

320 = k(5)( {4}^{2} )

320 = 80k

k = 4

196 = 4(1)( {q}^{2} )

49 =  {q}^{2}

q = 7

Cosine is a trigonometric function. The value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2. The correct option is A.

<h3>What is a cosine?</h3>

Cosine is the trigonometric function equal to the ratio of the side next to an acute angle to the hypotenuse in a right-angled triangle.

Given the value of cos(x)=-(√3)/2, therefore, the value of x can be written as,

cos(x) = -(√3)/2

(x) = cos⁻¹ [-(√3)/2]

x = 5π/6 = 150°

Now, the value of cos(x+π) will be,

cos(x+π)

= cos[(5π/6)+π]

= cos(11π/6)

= √3 / 2

Hence, the value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2.

Tonja is a married taxpayer who claims 2 withholding allowances. She earns
viva [34]

The amount that Tonja will save in Federal Income and FICA Taxes if she has her childcare expenses deducted from her check before taxes is: $26.17

<h3>What is Federal Income Tax?</h3>

Federal Income Tax is a tax that is levied by the Federal Government and most states in the United States of America. It comprises of 7 tax rates.

<h3>What is FICA Tax?</h3>

FICA Tax is a Federal Insurance Contributions Act Tax. This tax is levied on every payroll of employees to fund Social Security and Medicare programs. This is divided into two parts:

  • Social Security Tax which is 6.2% and
  • Medicare Tax which is 1.45%. The total is 7.65%

How to calculate Tonja's Tax before deduction

Federal Tax rate first level is 10% on 0$ - $19,900.

1) Hence, the first tax is 10% on $600, which is $60

2) The next tax is FICA. This is applied to the Gross Pay of $600.

Applying both taxed under FICA we have 7.65% * $600 = $45.9

Total Tax before a deduction is:

$60 + $45.9 = $105.6

The Tax Payable if childcare expenses is deducted first will be:

10% on $450     = $45

7.65% on $450 = $34.43

Total                   = $79.43

Hence the tax savings will be:

105.6 - 79.43 = $26.17

For each equation, enter two more equations using the same numbers that express the same relationship in a different way. 3+2=5
Zepler [3.9K]

Answer:

3 = 5 - 2

2 = 5 - 3

Step-by-step explanation:

Given

3 + 2 = 5

Required

Express in different ways

The first way is:

3 + 2 = 5

Subtract 2 from both sides

3 + 2 -2= 5 - 2

3 = 5 - 2 ------ (1)

Another way is:

3 + 2 = 5

Subtract 3 from both sides

3 - 3 +2 = 5 - 3

2 = 5 - 3 --- (2)
