From data gathered in the period 2008−2012, the yearly value of U.S. exports can be modeled by the function E(x) = −228x3 + 2,252.8x2 − 6,098.5x + 11,425.8 where x is the number of years after 2008 and E(x) is the value of exports in billions of dollars. The yearly value of U.S. imports can be modeled by the function I(x) = −400.4x3 + 3,954.4x2 − 11,128.8x + 17,749.6 where x is the number of years after 2008 and I(x) is the value of imports in billions of dollars. Estimate the total value the U.S. imported and exported in 2011. Round to the nearest whole number. About billion dollars were imported and exported by the U.S. in 2011.

how many times can 38 go into 192 using long division

Answers

Answer: 5.0526

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 38 on the left side and the dividend 192 on the right side like this:

           

 3 8 ⟌ 1 9 2

Step 2:

The divisor (38) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

       0    

 3 8 ⟌ 1 9 2

Step 3:

Multiply the divisor by the result in the previous step (38 x 0 = 0) and write that answer below the dividend.

       0    

 3 8 ⟌ 1 9 2

      0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

       0    

 3 8 ⟌ 1 9 2

     - 0    

       1    

Step 5:

Move down the 2nd digit of the dividend (9) like this:

       0    

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

Step 6:

The divisor (38) goes into the bottom number (19), 0 time(s). Therefore, put 0 on top:

       0 0  

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

Step 7:

Multiply the divisor by the result in the previous step (38 x 0 = 0) and write that answer at the bottom:

       0 0  

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

         0  

Step 8:

Subtract the result in the previous step from the number written above it. (19 - 0 = 19) and write the answer at the bottom.

       0 0  

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

     -   0  

       1 9  

Step 9:

Move down the last digit of the dividend (2) like this:

       0 0  

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

     -   0  

       1 9 2

Step 10:

The divisor (38) goes into the bottom number (192), 5 time(s). Therefore put 5 on top:

       0 0 5

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

     -   0  

       1 9 2

Step 11:

Multiply the divisor by the result in the previous step (38 x 5 = 190) and write the answer at the bottom:

       0 0 5

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

     -   0  

       1 9 2

       1 9 0

Step 12:

Subtract the result in the previous step from the number written above it. (192 - 190 = 2) and write the answer at the bottom.

       0 0 5

 3 8 ⟌ 1 9 2

     - 0    

       1 9  

     -   0  

       1 9 2

     - 1 9 0

           2

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 192 divided by 38 calculated using Long Division is: 5.0526

Find the value of p in the equation, 0.25p-50=240​

Answers

Answer:

p = 1160

Step-by-step explanation:

0.25p-50=240​

0.25p = 240+50 (Transfer the 50 and isolate the p)

[tex]\frac{1}{4}[/tex]p = 290 (Changing the decimal to a fraction so it is easier to see)

[tex]\frac{4}{4}[/tex]p = 4×290 ([tex]\frac{1}{4}[/tex]×4 = [tex]\frac{4}{4}[/tex])

p = 1160

Answer:

p=1160

Step-by-step explanation:

Its's easy. If there ever is any number with a letter in the equation, you are most likely to divide that number. First, since 50 has a minus in front of it, you have to add that to the 50 in the equation AND the 240. When you do 50 plus the 50 in the equation it cancels out because -50+50 is 0 (you don't add the 0 to the equation because you are looking for p.) So, 240+50 is 290. Now, you have to divide 0.25 to the 0.25p AND the 290. 0.25 divided by 0.25p is 1, BUT you never put 1p you just put p because p is the same as 1. 290 divided by 0.25 is 1160. So your equation should look like p=1160

What is Quadratic equation?

Any equation that can be transformed into standard form as follows is referred to as a quadratic equation in algebra (from the Latin quadratus, which means "square").Where x denotes an unknown and a, b, and c denote known values, respectively, with a 0, displaystyle ax2+bx+c=0 is used. Since there is no displaystyle ax2ax2 term, the equation is linear (if a = 0 and b 0) rather than quadratic.) The coefficients of the equation are the numbers a, b, and c, which can be separated by referring to them as the quadratic coefficient, linear coefficient, and constant or free term, respectively. As well as being referred to as the roots or zeros of the expression on the left-hand side of the equation, the values of x that satisfy it are known as solutions of the equation. There are only two possible answers to a quadratic equations The quadratic formula. The solutions are expressed in terms of a, b, and c by the expression sqrt b2 4ac 2a. There are numerous ways to obtain it, one of which is through completing the square.

Quadratic equation-based solutions to issues have been recognized since 2000 BC.The quadratic equation is referred to as "univariate" because there is just one unknown. The quadratic equation is a polynomial equation because all the powers of x that it contains are non-negative integers. Since the largest power is two, it is in particular a second-degree polynomial equation.

Triangle M was dilated by a scale factor of 1.2 to form triangle M. How does the area of triangle M'
relate to the area of triangle M?
A- The area of triangle M'is 0.6 times the area of triangle M.
B- The area of triangle M'is 1.2 times the area of triangle M.
C- The area of triangle M'is 1.44 times the area of triangle M.
D- The area of triangle M' is 2.4 times than the area of triangle M.

Answers

Answer:

The area of triangle M is 1.44 times the area of triangle M.

Step-by-step explanation:

From Geometry we remember that the area formula of the triangle is:

[tex]A = \frac{1}{2}\cdot b\cdot h[/tex] (1)

Where:

[tex]b[/tex] - Base of the triangle, dimensionless.

[tex]h[/tex] - Height of the triangle, dimensionless.

[tex]A[/tex] - Area of the triangle, dimensionless.

The dillation of the triangle by a scale factor means that:

[tex]A' = \frac{1}{2}\cdot b'\cdot h'[/tex] (2)

[tex]b' = k\cdot b[/tex] (3)

[tex]h' = k\cdot h[/tex] (4)

Where:

[tex]b'[/tex] - Dilated base of the triangle, dimensionless.

[tex]h'[/tex] - Dilated height of the triangle, dimensionless.

[tex]A'[/tex] - Dilated area of the triangle, dimensionless.

[tex]k[/tex] - Dilation factor, dimensionless.

If we know that [tex]k = 1.2[/tex], then the area formula for the dilated triangle is:

[tex]A' = \frac{1}{2}\cdot (k\cdot b)\cdot (k\cdot h)[/tex]

[tex]A' = k^{2}\cdot \frac{1}{2}\cdot b\cdot h[/tex]

[tex]A' = k^{2}\cdot A[/tex]

Therefore, the area of triangle M is 1.44 times the area of triangle M.

Answer:

C- The area of triangle M'is 1.44 times the area of triangle M.

What is combination?

Combinations are ways to choose things from a collection where the order of the choices is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.

The definition of the combination is "An arrangement of objects where the order of the objects is irrelevant." Combining the words indicates "Selection of things," where the order of the items is irrelevant.

Given total numbers of flavours = 26

number of dip = 6

Combinations allows us to create various sets of x components from a total of n elements, where their order is irrelevant and no member is repeated.

Combinations can be mathematically stated as:

ⁿCₓ = [tex]\frac{n!}{(n - x)!x!}[/tex]

we have n = 26

and x = 6

ⁿCₓ =  [tex]\frac{n!}{(n - x)!x!}[/tex]

²⁶C₆ = [tex]\frac{26!}{(26 - 6)!6!}[/tex]

26! = 26 x 25 x 24 x 23 x 22 x........ x 1

6! = 6 x 5 x 4 x 3 x 2 x 1

²⁶C₆ = 26!/(20!6!)

²⁶C₆ = 26 x 25 x 24 x 23 x 22 x 21 x 20!/(20!6!)

²⁶C₆ = 26 x 25 x 24 x 23 x 22 x 21/(720)

²⁶C₆ = 2,30,230

Hence the numbers of orders are 2,30,230.
