First a reciprocal is a fraction but flipped over. So so if we have x/y, it's recipricam is y/x.

this helps to know when you understand that dividing by a fraction is the same thing as multiplying by that fractions reciprocal.

So ifnwenhave b/c and divide it by x/y we can also say b/c multiplied by y/x. it isnthensame thing.

now to use this for your problem.

5/31 divided by 15/23
or
5/31 times 23/15

all we have to do is multiple the 2 numerator and denominator and get:
115/465

now to reduce. divide both by 5 first
23/91

both numbers are prime so that would be answer

Integrate with respect to x <br><br> 1/√(1-2x)

Ilia_Sergeevich [38]

Answer:

-√(1 - 2x) + C

Step-by-step explanation:

1/√(1-2x)

We want to integrate it. Thus;

∫1/√(1 - 2x) dx

Let u = 1 - 2x

Thus;

du/dx = -2

Thus, dx = -½du

Thus,we now have;

-½∫1/√(u) du

By application of power rule, we will now have;

-½∫1/√(u) du = -√(u) + C

Plugging in the value of u, we will have;

-√(1 - 2x) + C

Answer:

Step-by-step explanation:

Use the formula for radius and circle circumference.

$d=2r \\ \\ C=2\pi r$

Since we know the diameter, if we divide that by 2, we can get the radius.

$29.5/2=14.75$

Now we can plug that value into the circumference formula to get the circumference.

$C=2(14.75)\pi \\ \\ C=29.5\pi \\ \\ C=93$

*Since we're rounding to the nearest inch.

Part C

makkiz [27]

a = 1, b =14 and y-coordinate is 6 when x = 0.

Solution:

Let us first write the equation of a line.

Take the points are (2, 2) and (6, 10).

Slope of the line:

$$m=\frac{y_2-y_1}{x_2-x_1}$

$$m=\frac{10-2}{6-2}$

$$m=\frac{8}{4}$

m = 2

Point-slope formula:

$y-y_1=m(x-x_1)$

y - 10 = 2(x - 2)

y - 10 = 2x - 4

Add 10 on both sides,we get

y = 2x + 6

Equation of a line is y = 2x + 6.

To find (a, 8), substitute x = a and y = 8 in the equation,

8 = 2a + 6

Subtract 6 from both sides, we get

2 = 2a

a = 1

To find (4, b), substitute x = 4 and y = b in the equation,

b = 2(4) + 6

b = 8 + 6

b = 14

Substitute x = o in the equation.

y = 2(0) + 6

y = 6

The y-coordinate is 6 when x = 0.

Please find the unknown with all steps

kirill [66]

Answer:

see explanation

Step-by-step explanation:

Since AC = BC then ΔABC is isosceles with base angles

∠BAC =∠ABC, thus

3x + x = 70

4x = 70 ( divide both sides by 4 )

x = 17.5

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

∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence

y = 70 + x = 70 + 17.5 = 87.5
