What is the sign of 37+(-37)? Choose 1 answer: Positive Negative Neither positive nor negative the sum is zero

Hello!

We have the following multiplication:

To solve it, we have to multiply numerator with numerator and denominator with denominator, look:

So, the fraction in is the simplest form is 9/20.

The numeric value of the slope of the inverse function at x = -32 is given by:

(h^-1)'(-32) = 0.03.

To find the inverse of a function, we exchange x and y in the original function, then isolate y.

This means that if the original function has a point (x,y) graphed, the inverse will have point (y,x) graphed.

From it's graph, the function h(x) has these two following points:

(-4.552, -32) and (-4.555, -32.1)

Hence the inverse will have these two following points:

(-32, -4.552) and (-32.1, -4.555).

The slope is given by change in y divided by change in x, hence:

(h^-1)'(-32) = (-4.552 - (-4.555))/(-32 - (-32.1)) = 0.03.

Which is also equivalent to the derivative of the inverse function at x = -32.

Answers:

a) 32500

b) 0.00604

c)  2.4 * 10^6

d) 1.47 * 10^(-3)

===================================================

Explanation:

The exponent over the 10 tells us how many spaces to move right or left.  If the exponent is positive, we move right. If negative, we move left. Think of a number line.

For part (a), the exponent is 4. So we move the decimal point 4 spaces to the right.

The 3.25 then becomes 32500

--------------

In part (b), the exponent -3 means we move 3 spots to the left to go from 6.04 to 0.00604

---------------

Part (c)

Place the decimal point between the first two digits and erase the zeros to get 2.4

Then we need to move the decimal point 6 spots to the right to get back to 2,400,000 again

Therefore we can say 2,400,000 = 2.4*10^6

---------------

Part (d)

Place the decimal point just after the first nonzero digit, and erase the zeros to the left to get 1.47

We must move the decimal point 3 spots to the left to go from 1.47 back to 0.00147 again

It means 0.00147 = 1.47*10^(-3)

The given group of equations represents a system of non-linear      equations.

A mathematical equation must take the form y = m x +b in order to be classified as a linear function (in which m is the slope and b is the y-intercept). This form cannot be satisfied by a nonlinear function.

Only first degree variables and terms that contain the products of variables are present in a linear equation.

However, in the case of nonlinear equations, either the equation comprises a product of variables or at least one of the variables is not of the first degree.

If the graph of an equation is a straight line, the equation is linear. Otherwise, if the power of x is more than one, then it is nonlinear.

The given equations has the degree more than 1 and their graph is also not a straight line.

Hence, the given group of equations represents a system of non-linear      equations.

  (b)  4.65×10⁹

Step-by-step explanation:

You want 4,650,000,000 written in scientific notation.

A number is written in scientific notation in the form shown in the second attachment. The coefficient has one digit to the left of the decimal point. The remaining significant digits of the number are to the right of the decimal point.

The exponent is the same as the exponent of the place value of the most significant digit of the number. Some of those exponents are shown in the first attachment.

The given number has its most significant digit (4) in the "billions" place. The corresponding exponent of 10 is 9. Putting 4 to the left of the decimal point, the number is written in scientific notation as ...

  4.65×10⁹

Additional comment

In the above, we have used the superscript font to indicate the exponent. In plain text, an exponent is indicated with a caret (^), as in 4.65·10^9.

If you use an "x" character for a multiplication symbol, you need to make sure it cannot be confused with a variable named "x".

In spreadsheets and some calculators, the base and exponent are written as "E". Here, the number would be 4.65E9. (This is a carryover from one of the earliest high-level computer programming languages.)

Note the 3 decimal places after the dot is the thousandth's place. Note that we can either write the last digit or omit it.

The earnings and deductions, are given as follows:

First we find her gross earning, which is given by the hourly wage multiplied by the number of hours worked, hence:

Gross pay = 40 x 18 = $720.

Hence her yearly income is given by:

Yearly income = 52 x 720 = $37440.

Meaning that her federal tax rate is of $19.76 a week plus 12% of the excess over $197.60, then:

Federal tax = 19.76 + 0.12 x (720 - 197.60) = $82.45.

The social security tax rate is of 6.2% of her gross weekly earnings, hence it is given by:

Social Security = 0.062 x 720 = $44.64.

The medicare tax rate is of 1.45% for Lynn(employee), hence:

Medicare = 0.0145 x 720 = $10.44.

The state tax is 3% of her gross earnings, hence:

State tax = 0.03 x 720 = $21.60.

The local tax is 1.5% of her gross earnings, hence:

State tax = 0.015 x 720 = $10.80.

The medical and union dues are stated in the problem, hence the sum of all discounts is given by:

82.45 + 44.64 + 10.44 + 21.60 + 10.80 + 35 + 17 = $221.93.

The net pay is the gross pay subtracted by the discounts, hence:

Net pay = 720 - 221.93 = $498.07.

Step-by-step explanation:

"with replacement" is important.

that means that the mixture of the marbles and therefore the chances to pull certain marbles does not change with the previous pull.

a probability is always

desired cases / totally possible cases

we have 14 marbles in the bag

4 orange

2 green

8 purple

the probability to pull an orange marble is therefore

4/14 = 2/7

the probability to pull a green marble is therefore

2/14 = 1/7

the probability to pull a purple marble is therefore

8/14 = 4/7

a.

a green marble is pulled AND then a purple marble is selected.

we need to combine both probabilities for one combined event :

1/7 × 4/7 = 4/49

b.

a purple marble and then a green marble is selected.

4/7 × 1/7 = 4/49

since we replace the marbles after every pull, both probabilities are the same, of course.

every pull has the same probability for each desired event.

c.

2 orange marbles are selected.

2/7 × 2/7 = 4/49

d.

2 non-orange marbles are pulled

there are 10 non-orange marbles. so this is

10/14 × 10/14 = 5/7 × 5/7 = 25/49

Answer:

  2) see attachment

Step-by-step explanation:

Given a figure composed of 21 squares that each have an area of 25 square units, you want to know (1) the perimeter of the figure, and (2) how to rearrange it to have the same perimeter, but with sides that line up.

The perimeter is the sum of the lengths of the sides that form the boundary of the figure. The boundary consists of ...

for a total of 6·4 = 24 edges of the squares shown.

Each of the squares shown has an area of A = s² = 25 units², so a side length of s = √(25 units²) = 5 units.

The perimeter is the length of 24 of these edges, so is ...

  perimeter = 24 × 5 units = 120 units

The 21 squares shown in the figure can only be rearranged into rectangles that are 21 × 1 squares or 7 × 3 squares. These will have perimeters of 44 or 20 edges, respectively. Hence, it is not possible to have "sides of the squares line up" in a rectangle with the same perimeter.

The attached figure is the next best thing. It shows a 6 × 4 rectangle with three squares removed (to keep the total at 21). The number of horizontal and vertical edges total 24, as required to keep the same perimeter.
