Simplify negative 4 and 1 over 4 − negative 9 and 1 over 2. Help ;---;

Answer:

s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

Step-by-step explanation:

Take the integral:

integral cos^(-1)(-(q^2 s)/2) ds

For the integrand cos^(-1)(-(q^2 s)/2), substitute u = -(q^2 s)/2 and du = -q^2/2 ds:

= -2/q^2 integral cos^(-1)(u) du

For the integrand cos^(-1)(u), integrate by parts, integral f dg = f g - integral g df, where  

f = cos^(-1)(u), dg = du, df = -1/sqrt(1 - u^2) du, g = u:

= -(2 u cos^(-1)(u))/q^2 + 2/q^2 integral-u/sqrt(1 - u^2) du

Factor out constants:

= -(2 u cos^(-1)(u))/q^2 - 2/q^2 integral u/sqrt(1 - u^2) du

For the integrand u/sqrt(1 - u^2), substitute p = 1 - u^2 and dp = -2 u du:

= -(2 u cos^(-1)(u))/q^2 + 1/q^2 integral1/sqrt(p) dp

The integral of 1/sqrt(p) is 2 sqrt(p):

= (2 sqrt(p))/q^2 - (2 u cos^(-1)(u))/q^2 + constant

Substitute back for p = 1 - u^2:

= (2 sqrt(1 - u^2))/q^2 - (2 u cos^(-1)(u))/q^2 + constant

Substitute back for u = -(q^2 s)/2:

Answer: = s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

Answer:

4 1/8

Step-by-step explanation:

1 1/8 x 3 2/3 = ?

9/8 x 11/3 = 99/24

99/24 = 4 1/8

Answer:

1. find the least common denominator for the left-hand side fraction. This brings you to 8/8x + 3x/8x = 1/2

2. Add the numerator on the left-hand side of this equation, (8+3x)/8x = 1/2

3. Multiply both sides by 2, that will lead you to (8+3x)/4x =1/1

4. Multiply both sides by 4x, we get 8+3x=4x

5. Finally, subtracting 3x from both sides simplifies the equation to x=8. Note that this is as simple as this expression can get so you can not go any further, therefore 1/x+3/8=1/2 simplifies to x=8.

Answer:

Step-by-step explanation:

Given that:

Number of books, b α number of children enrolled

b α C

b = kC

Number of books, b = 3 for each child, c = 1 enrolled

Total number of books in class room :

Total number of books = Number of books per child * Number of child)

Total number of books = 3 * Numbe of child

Answer:

Step-by-step explanation:

∠RST=180-44-15

         =121°

In ΔRST and ΔLMN,

∠RST=∠LMN (proven)

∠TRS=∠NLM (given)

∴ΔRST ~ ΔLMN (AA)

Answer:

Yes

Step-by-step explanation:

If all the angles in the triangles are the same, then the triangles are similar.

ΔSRT: The angles in a triangle add up to 180. 44+15+x=180, x=121

ΔLMN: The angles in a triangle add up to 180. 44+121+x=180, x=15

Both triangles share the same angles (44,15 and 121), so they are similar.

Answer:

₹2520

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 12600 × 0.1 × 2 = 2520

I = ₹ 2,520.00

The simple interest accumulated

on a principal of ₹ 12,600.00

at a rate of 10% per year

for 2 years is ₹ 2,520.00.

Answer:

[tex]First~condition:\\Suppose~that~the~first~house~costs~4x~and~the~second~house~costs~3x.\\Given,~Cost~of~the~second~house=Rs. 420000\\or, 3x=Rs. 420000\\or, x = Rs. 140000\\Cost~of~the~first~house=4x= 4(140000) = Rs. 560000\\So, ~the~cost~of~first~house~is~Rs.560000\\Second~part:\\Now,~the~cost~of~the~first~house = Rs.(560000+70000) = Rs. 630000\\But,~the~cost~of~second~house~is~still~Rs. 420000\\Their~ratio= 630000:420000 = \frac{630000}{420000}=\frac{3}{2}=3:2.\\[/tex]

So, the ratio of their cost is 3:2.

Answer:

option a c d are correct

Step-by-step explanation:

    Since, the item was burried at the midpoint of the segment joining bowl and the tool. Archaeologist should dig at the midpoint which is at (2, 7).

        Mid-point = [tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

Given points representing a bowl and a tool are (1, 4) and (3, 10).

Since, an item is burried at the midpoint of the segment joining bowl and tool,

Use the expression for the position of the mid-point of the segment.

Position of the item → [tex](\frac{1+3}{2},\frac{4+10}{2})[/tex]

                                 → (2, 7)

       Hence, position of the burried item will be at (2, 7).

Answer:

The answer is B. M'(-6,9) and N'(3,9)

Step-by-step explanation:

To find the coordinates of the endpoints of segment M'N' you'll have to use the rule through which it was dilated.

M(-4,6) after the rule it will be (-4*1.5, 6*1.5) = M'(-6,9)

N(2,6) after the rule it will be (2*1.5, 6*15) = N'(3,9)

The answer is B. M'(-6,9) and N'(3,9)

Hope this helps :)

The required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.

Here,
The equation for the dilation is given as,
= {1.5x, 1.45y}

Now,
Put coordinates of M and N in the above equation,
Coordinate of M' = (-4×1.5, 6×1.5) = M'(-6,9)

Similarly, the coordinate of N',
Coordinate of N' = (2×1.5, 6×1.5) = N'(3,9)

Thus, the required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.
