You are solving a measurement problem where the numbers 2.09*10^(9) and 4.053 × 10^−4 are divided. How many significant digits should the quotient have?

By removing the taxes from the gross pay, we can see that Carlos' net pay is 1,320.30 dollars.

To get Carlos' net pay, we need to take his gross pay, which is $1,800.00 and subtract all the taxes shown here.

The taxes (in percentage) are:

The total percentage in these taxes is 19% + 6.2% = 25.2%

Then a 25.2% of the gross pay will be gone in taxes, then we need to subtract:

0.252* $1,800.00 = $453.60

We also need to subtract the $26.10 for Medicare, then we will get that Carlos' net pay is given by the expression:

$1,800.00 - $26.10 - $453.60 = $1,320.30

We conclude that, after taxes and that, Carlos' net pay is 1,320.30 dollars.

Answer:

1000

Step-by-step explanation:

The equation is,

→ 34.624 × x = 34624

Solving for the value of x,

→ 34.624 × x = 34624

→ x = 34624/34.624

→ [ x = 1000 ]

Thus, value of x is 1000.

Answer:

25:15

Hope this helps :)

Step-by-step explanation:

5:3 so since there is 25 dogs we had to multiply 5 to the 5 in 5:3. We will have to multiply 5 to the 3 in 5:3 to get number of cats.

5:3 = 25:15

Answer:

[tex] = 15[/tex]

Step-by-step explanation:

Taking that the ratio of dogs to cats is 5:3, then:

The number of dogs = 25, so:

[tex]5 = 25 \\ 3 = x \\ x= 25 \times 3 \div 5 \\ x = 15[/tex]

Part 1

[tex](f+g)(x)=f(x)+g(x) \\ \\ =(6x+3)+(x^2 +10x-7) \\ \\ =\boxed{x^2 + 16x-4}[/tex]

Part 2

[tex](f-g)(x)=f(x)-g(x) \\ \\ =(6x+3)-(x^2 +10x-7) \\ \\ =6x+3-x^2-10x+7 \\ \\ =\boxed{-x^2 - 4x+10}[/tex]

Part 3

[tex](f\cdot g)(x)=f(x) \cdot g(x) \\ \\ =(6x+3)(x^2 +10x-7) \\ \\ =6x^3 + 60x^2 - 42x+3x^2 + 30x-21 \\ \\ =\boxed{6x^3 + 63x^2 - 12x-21}[/tex]

Part 4

[tex]\left(\frac{f(x)}{g(x)} \right)=\frac{f(x)}{g(x)} \\ \\ =\boxed{\frac{x^2 + 10x-7}{6x+3}}[/tex]

Answer:

185,104 is between 100,000 and 200,000.

Hope this helps :)

Step-by-step explanation:

100,000 comes before 185,104 and 200,000 comes after 185,104.

Based on the population of Brazil in 1855 and 1860, the estimated population in 1870 is C. 19.15 million

The increase in the population between 1855 and 1860 was:

= 12.51 - 10.112

= 2.398 million

The increase is:

= 2.398/10.112

= 24%

With an increase of 24% every 5 years, the population in 1870 is:

= 10.112 x (1 + 24%)³

= 19.27 million

In conclusion, we can estimate that the population of Brazil in 1870 was 19.15 million.

Nancy had $ 250 at the start when she did not buy anything given by the equation $ 100 = 2 x / 5

Let the original amount Nancy have first be x.

Therefore, Money spent on dress =  x / 5

Remaining money = x - x / 5

= 4 x / 5

Money spent on handbag = (1 / 4) × 4 x / 5

= x / 5

Total total money spent is given by the equation:

= x / 5 + x / 5 = $ 100

$ 100 = 2 x / 5

2 x = $ 500

⇒ x = $ 500 / 2

⇒ x = $ 250

Option 3

Step-by-step explanation:

See attached image.

The relation defined by the given set of coordinates → (1, 4) , (−1, −2 ) , (3, 10) , (5, 16) represents a function.

A function is relation between a dependent [x] and independent [y] variable . The value of the dependent variable [y] depends upon the value of the independent variable [x].

Given is a relation defined by the following set of coordinates -

(1, 4) , (−1, −2 ) , (3, 10) , (5, 16).

For a given relation, defined by the given set of coordinates to be a function, there should be a unique value of y-coordinate for a unique value of x-coordinate. However, the value of y-coordinate can be same for different values of x-coordinates. From the relation given, we can see that -  for every value of x, there are unique values of y. Hence, the given relation is a function.

Therefore, the relation defined by the given set of coordinates → (1, 4) , (−1, −2 ) , (3, 10) , (5, 16) represents a function.

Explanation:

The first digit must be even, so we have this subset {2,4} to pick from for that first digit. There are 2 choices here.

Whatever is picked for the first digit cannot be re-selected. So we have 5-1 = 4 choices left for the second digit, and then 4-1 = 3 choices for the third digit.

Overall we have 2*4*3 = 24 different passcodes.

I suppose you mean

[tex]f(x) f(y) = f(x + y) + f(x - y)[/tex]

Let [tex]x=1[/tex] and [tex]y=0[/tex]. Then

[tex]f(1) f(0) = f(1 + 0) + f(1 - 0) \implies f(1) f(0) = 2 f(1) \implies f(0) = 2[/tex]

Now if we fix [tex]y=1[/tex], the functional equation reduces to the recurrence relation

[tex]f(x) f(1) = f(x + 1) + f(x - 1) \implies f(x+1) - 3f(x) + f(x-1) = 0[/tex]

and we can find [tex]f(7)[/tex] with a few rounds of substitution.

[tex]x=1 \implies f(2) - 3f(1) + f(0) = 0 \implies f(2) = 3f(1) - f(0) = 7[/tex]

[tex]x=2 \implies f(3) - 3f(2) + f(1) = 0 \implies f(3) = 3f(2) - f(1) = 18[/tex]

[tex]x=3 \implies f(4) - 3f(3) + f(2) = 0 \implies f(4) = 3f(3) - f(2) = 47[/tex]

[tex]x=4 \implies f(5) - 3f(4) + f(3) = 0 \implies f(5) = 3f(4) - f(3) = 123[/tex]

[tex]x=5 \implies f(6) - 3f(5) + f(4) = 0 \implies f(6) = 3f(5) - f(4) = 322[/tex]

[tex]x=6 \implies f(7) - 3f(6) + f(5) = 0 \implies f(7) = 3f(6) - f(5) = \boxed{843}[/tex]
