Following the order of operations, exponents should be simplified after completing all multiplication and division. True False well PEMDAS ^ its 2nd in line... i dont understand what they mean

Unless the exponet is on the outside of a parentheses then the exponet should be done first.

Example

(5x5)^2 - Inside the parentheses should be done first
and it ends up being - 625

But if the exponet is on the inside

(5x5^2) Then do the math for the exponet first
Then it becomes - 125

A boat that costs $8550 decreases in value by 12% per year. How much will the boat be worth after 3 years?

You have to take $8,550 times 0.12 (12%) to find out the number it is being decreased by.
8,550 x 0.12 = 1,026
And then, you have to subtract 1,026 from 8,550 three times for three years and your answer becomes 5,472.
$5,472

The number is 717, 
You would simply get the answer by looking at all context clues. Hundreds = same as digit in ones, which is 700. Tens = 10. And ones = 7. Therefore, your answer would be 700. Also can be put as 700 + 10 + 7 = 717.

QUESTION POSTED AT 23/09/2019 - 04:25 AM

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.

Y = kx
We have to find k value, so lets say x is euros and y is American dollars
so we have
9 = k(8)
k = 1.125
so the equation will be  y = 1.125x
to prove it use another value given
y = 1.125x
y = 1.125 (24)
 y = 27
Thus 24 euros is 27 dollars.
Hence the equation y =1.125x is correct.

You are given the table below. x 4 8 12 16 20 f(x) 11 25 16 9 31 Use the table and n = 4 to estimate the following. Because the data is not monotone (only increasing or only decreasing), you should sketch a possible graph and draw the rectangles. 20 (integral) f(x)dx 4

Solution:

X      4      8       12       16          20

F(x)   11      25      16       9           31

A function is said to be increasing if , x_{1}> x_{2}, then f(x_{1})>f(x_{2}) {\text{and decreasing if } x_{1}> x_{2}, then f(x_{1})<f(x_{2}).

As you can see from the table given as x increases , f(x) increases as well as decreases.

So it is increasing as well as decreasing function.

Now plotting the graph on two dimensional coordinate plane and drawn perpendicular from these points on X axis.

\int_{4}^{20}f(x)dx=\int_{4}^{8}f(x)dx+\int_{8}^{12}f(x)dx+\int_{12}^{16}f(x)dx+\int_{16}^{20}f(x)dx

Equation of line joining two points (x_{1},y_{1}), and (x_{2},y_{2}) is \frac{y-y_{1}}{x-x_{1}}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Equation of line joining two points (4,11) and (8,25) is

4(y-11)=14(x-4)

4 y -44 = 14 x -56

4 y = 14 x -12

y= \frac{7x}{2}-3 --------(1)

Area under line (1) is

\int_{4}^{8}f(x)dx=\int_{4}^{8}(\frac{7x}{2}-3) dx=\frac{7x^2}{4}-3x\left \{ {{x=8} \atop {x=4}} \right. =112-24-28+12=72

Equation of line joining (8,25) and (12,16) is

4(y-25 )= -9(x-8)

4 y - 100= -9 x + 72

4 y = -9 x + 172

y = \frac{-9x}{4} +43--------(2)

Area under line 2 is

\int_{8}^{12}f(x)dx=\int_{8}^{12}(\frac{-9x}{4} +43)dx=\left \{ {{x=12} \atop {x=8}}   \frac{-9x^2}{8} +43x = -162 +516+72-344=82

Equation of line joining (12,16) and (16,9) is

-4(y-16) = 7(x-12)

-4 y + 64= 7 x -84

-4 y = 7 x -148

y = \frac{-7x}{4} +37-----------(3)

Area under the line 3 is

\int_{12}^{16}f(x)dx=\int_{12}^{16}(\frac{-7 x}{4} +37)dx=\left \{ {{x=16} \atop {x=12}}   \frac{-7x^2}{8} +37 x = -224 +592+126-444=50

Equation of line joining (16,9) and (20,31) is

4(y-9) = 22(x-16)

4 y - 36 = 22 x - 352

4 y = 22 x - 316

y= \frac{11x}{2}-79---------(4)

Area under the line 4 is

\int_{16}^{20}f(x)dx=\int_{16}^{20}(\frac{11 x}{2} -79)dx

=\left \{ {{x=20} \atop {x=16}}   \frac{11x^2}{4} -79 x = 1100-1580-704+1264=2364-2284=80


Total Area = Area under the line (1+2+3+4)

=\int_{4}^{20}f(x)dx=\int_{4}^{8}f(x)dx+\int_{8}^{12}f(x)dx+\int_{12}^{16}f(x)dx+\int_{16}^{20}f(x)dx

= 72 +82+50+80

= 284 square units

You can find area using the formual of area of trapezoid which is = \frac{1}{2}[Sum of parallel sides]× [perpendicular distance between them]
