Thank u!

Thanks Chilledz3non :)

Hi Mellie,

I don't know if you have done trigonometry yet.  There is almost always more than 1 way to do these questions.

If you need them done in a different way then you need to tell us !        

1 foot=12 inches

7 X 12=84 inches

84 + 5.5=89.5 inches

89.50 / 2=44.75 inches is the center or the middle

44.75/12=3 feet and 8.75 inches-the center or the middle.

Where do you want to put the square?

Since it iws a 2 dimensional object you could put it on a peice of paper. ://

Did you mean something else??

Simplify the following:
-1+6--8

-(-8)  =  8:
-1+6+8

6+8 = 14:

Answer: | 13

No, it is infinity!. It is just too big for this calculator. It is very BIG NUMBER. It is 6,230 digits long!.

Maybe you should just use a calculator next time.

H**l no .....WRONG!    They are only CHILDREN...you can have ALL of the chocolates.   

Actually ....6 children PLUS YOU = 7    so only 12/7 chocolates each....

Learn to use the calculator here. Enter the first big number, then press / sign, then enter 4 followed by = key. That should give you the answer.

Let length=L

Let width =W

L^2 + W^2=41^2

2[L + W] =98

2L + 2W=98

2L=98 - 2W

2L=2[49 - W] divide both sides by 2

L=49 - W Substitute

[49 - W]^2 + W^2=41^2=1,681

Solve for W:
(49-W)^2+W^2 = 1681

Expand out terms of the left hand side:
2 W^2-98 W+2401 = 1681

Divide both sides by 2:
W^2-49 W+2401/2 = 1681/2

Subtract 2401/2 from both sides:
W^2-49 W = -360

Add 2401/4 to both sides:
W^2-49 W+2401/4 = 961/4

Write the left hand side as a square:
(W-49/2)^2 = 961/4

Take the square root of both sides:
W-49/2 = 31/2 or W-49/2 = -31/2

Add 49/2 to both sides:
W = 40 or W-49/2 = -31/2

Add 49/2 to both sides:
Answer: | W = 40                      or                 W = 9

i think its 32

Hi guests :)

How would you simplify this? sqrt(52)*sqrt(48)+9*sqrt(52)

\(\sqrt{52}*\sqrt{48}+9*\sqrt{52}\\ = \sqrt{4*13}*\sqrt{16*3}+9*\sqrt{4*13}\\ = 2\sqrt{13}*4\sqrt{3}+9*2\sqrt{13}\\ = 8\sqrt{39}\qquad\;\;\;+18\sqrt{13}\\\)

Exactly as guest already said :)

$40.00 jeans; 20% discount

40 - (20/100 X 40)=$32 Cost of jeans after 20% discount.

sin(theta) =26/30

Asin(26/30)=Theta=~60 degrees

Simplify the following:
sqrt(52) sqrt(48)+9 sqrt(52)

sqrt(52)  =  sqrt(2^2×13)  =  2 sqrt(13):
2 sqrt(13) sqrt(48)+9 sqrt(52)

sqrt(48)  =  sqrt(2^4×3)  =  2^2 sqrt(3):
2 sqrt(13)×2^2 sqrt(3)+9 sqrt(52)

2^2 = 4:
2 sqrt(13)×4 sqrt(3)+9 sqrt(52)

sqrt(52)  =  sqrt(2^2×13)  =  2 sqrt(13):
2 sqrt(13)×4 sqrt(3)+9×2 sqrt(13)

2×4  =  8:
8 sqrt(13) sqrt(3)+9×2 sqrt(13)

sqrt(13) sqrt(3) = sqrt(13×3):
8 sqrt(13×3)+9×2 sqrt(13)

13×3  =  39:
8  sqrt(39 ) +9×2 sqrt(13)

9×2  =  18:
8 sqrt(39)+18 sqrt(13)

Factor 2 out of 8 sqrt(39)+18 sqrt(13) giving 2 (4 sqrt(39)+9 sqrt(13)):
Answer: | 2 (4 sqrt(39)+9 sqrt(13))

Hi Chilledz3non,

x is between -3 and 4

x can be -2,-1,0,1,2,3, and even 4 because the 4 dot is coloured in.   It cannot be bigger than 4 so     \(x\le4\)

x cannot be  -3 because the -3 dot is Not coloured in, but it can be any number bigger than -3 (up to 4)

\(x>-3\\ \mbox{turn this around and you get }-3<x\\~\\so\\ -3<x\le4\)

SO   C is correct.

If you take 2 off all 'sides' you get        \(-3-2<x-2\le4-2\\ -5<x-2\le2\)

Ths would also be true but it is not one of your choices.

When x is between 2 values you ALWAYS use the   \(< or \le \;\;\;signs\)

Let length=L

Let width =W

L^2 + W^2=41^2

2[L + W] =98

L = 40 and W = 9

Area= L X W=40 X 9=360

One way to find the area of a parallelogram is the use the formula:  Area  =  (a)(b)(sin(C))

where  a  and  b  are the lengths of two adjacent sides and  C  is the size of the included angle.

Since a rhombus is a parallelogram:  a = 6,  b = 6,  and  C = 120^o .

Area  =  (6)(6)(sin(120))  =  31.18  (approximately)

Since all 4 sides are equal, this is a rhombus.

The diagonals of a rhombus intersect at their midpoint.

If the midpoint is labeled "X", then AX = 7  and  BX = 24.

Also, the diagonals of a rhombus are perpendicular to each other; this means that triangle AXB is a right triangle with a right angle at corner X.

Using the Pythagorean Theorem:  AX² + XB²  = AB²     --->     (7)² + (24)²  =  (AB)²      --->     49 + 576  =  (AB)²

     --->     625  =  (AB)²     --->     AB = 25

Since all four sides are equal, the perimeter  =  4 x 25  =  100

Hey there Mellie

In order to solve for the area of the parallelogram, you need to use this equation:

S= absinθ

Basically what this is:

S = the area

"a" and "b" = The the base and side; which in your case are 6 and 8 

θ= The known interior angle, 45° 

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

Plug all these variables into the equation and you will get this:

S = (6)(8)(sin 45°)

S= 33.94 

[So the area of the parallelogram is 33.94 ]

Take the integral:
integral (3 x^2-2/x+1337) dx
Integrate the sum term by term and factor out constants:
  =  3 integral x^2  dx-2 integral 1/x dx+1337 integral 1 dx
The integral of x^2 is x^3/3:
  =  x^3-2 integral 1/x dx+1337 integral 1 dx
The integral of 1/x is log(x):
  =  x^3-2 log(x)+1337 integral 1 dx
The integral of 1 is x:
Answer: | =  x^3+1337 x-2 log(x)+constant

To change a graph into the inequality, write

the left-hand value first 

then either a "<" sign (if the left-hand endpoint circle is open) or a "<=" sign (if the left-hand endpoint circle is filled in)

then an "x"

finally either a "<" sign (if the right-hand endpoint circle is open) or a "<=" sign (if the right-hand endpoint is filled in).

Thus, the answer is C)

Another way to do this is to place the original problem in the form:  ax² + bx + c  =  0

and then find the value of the discriminant:  b² - 4ac  (the portion under the square root sign in the quadratic formula).

If this value is zero, there will be one answer; if this value is positive, there will be two (unequal) real answers; if this value is negative there will be two (unequal) imaginary answers.

5  =  17x² - 200x     --->     subtract 5 from both sides and exchange the sides    --->     17x² - 200x - 5  =  0

So,  a = 17,   b = -200,  and  c = -5

b² - 4ac  =  (-200)² - 4(17)(-5)  =  40340

Since this value is positive, there will be two, unequal, real answer.

Add down the columns, you will get:  3x²  =  432

Divide by 3:                                          x²  =  144

Find the square root:                             x  =  12  or  x  =  -12

If  x = 12:  substitute into the first equation:  (12)² + y²  =  289

                                                                       144 + y²  =  289

                                                                                 y²  =  145

To solve this, find the square root; but the instructions say that you should find b, which is this number:  145.

The answer is (B)  145.
