\(a^{2}+b^{2}= c^{2}\)

a =(8-4)... b=(13-7)

a=4, b=6

therefore...

\(a^{2}+b^{2}= c^{2}\\4^{2}+6^{2}=c^{2}\\16+36=c^{2}\\52=c^{2}\\c=\sqrt{52}\)

Answer:

$80

Step-by-step explanation:

the original price (in percent) = 100%

the discount (25% off) = - 25%

_________________

the sale price (in percent) = 75% =>

equal to $60

so, the original price =

100/75 × $60 = $80

Now

\(\\ \rm\longmapsto 100-25=75\%\)

\(\\ \rm\longmapsto \dfrac{75}{100}x=60\)

\(\\ \rm\longmapsto x=60\times \dfrac{100}{75}\)

\(\\ \rm\longmapsto x=80\)

Answer:

144 days

Step-by-step explanation:

Let's put the efficiency in terms of   b

m = 3b      w = 2b       b=b

starting with    6 m  = 18 b

                        8w =   16 b

                        16b = 16 b           total 50 b

then increase   12m = 36b

                         18w = 36b

                         28b = 28 b    total = 100 b

You doubled 'b'  workers  so work time will be halved     to  144 days

To make the ratios equivalent, we can use the numbers 3 and 6:

3 : 1 is equivalent to 6 : 3

To complete the ratios and make them equivalent, we need to find two numbers from the given set (3, 4, 6, 12, 15) that can be used to replace the question marks.

Let's start with the first ratio: ? : 1

We need to find a number that, when divided by 1, gives an equivalent ratio. Since any number divided by 1 is itself, we can choose any number from the given set for the first ratio. Let's choose 3 for this example. So, the ratio becomes:

3 : 1

Now, let's move on to the second ratio: ? : 3

Similarly, we need to find a number that, when divided by 3, gives an equivalent ratio. Looking at the given set, we see that 6 is divisible by 3. So, the ratio becomes:

6 : 3

Answer:

b

Step-by-step explanation:

The image of D surely lies on the ray BA ,as ray BA is antiparallel to the ray BD.

Consider D’ to be the image of point D obtained ,when D is rotated 180 degrees anti-clockwise(or counter-clockwise),with B as center of rotation.

From the image above,it is clear that the rays BA and BD are antiparallel.

A ray is a segment of a line with a starting point and an infinite length in one direction.

Antiparallel rays are the rays which are parallel but oppositely directed.The angle between such rays is 180 degrees.

Hence,D’ must lie on the ray BA, as ray BA is antiparallel to BD(i.e the angle between the rays is also 180 degrees).

Answer:

Bottom left

Step-by-step explanation:

Let's look at it as (1/3)^x first. This function would have a y-intercept of (0,1) (because (1/3)^0 is 1), and would then become (1/3) times smaller for every 1 unit increment of x. This would look like the top left graph in these options. However, we are given (1/3)^-x, which means, in terms of transformations, that the graph is flipped across the y-axis. Algebraically, this looks like (1/3)^(-x) which equals to  \(\frac{1}{(1/3)^x}\), which simplifies down to 3^x, which would look like the bottom left graph.

Answer:

y= -5/3x + 5 2/3

Step-by-step explanation:

Slope of line times the slope of perpendicular line is =-1

3/5 is the slope of y=3/5x-6

3/5*x=-1, x=-5/3 is slope of our line

y-4=-5/3(x-1)

y-4=-5/3x+1 2/3

y=-5/3x+5 2/3

Answer:

For a line to be parallel it must have the same slope. So the slope of the new equation is 6.

The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....

-5=6(3)+b

Solve for b (the y-intercept)

b= -23

Therefore.... y=6x-23

The equation of the line is written in the different forms

Calculate the slope (m) using the formula:

m = (0 - 6) / (8 - 0)

m = -6 / 8

m = -3/4

Plug in the slope (m) and one of the given points (x1, y1) into the slope-intercept form to find the y-intercept (b):

y = mx + b

6 = (-3/4)(0) + b

6 = b

Substitute the y-intercept (b) into the equation:

y = (-3/4)x + 6

In point-slope form:

y - y1 = m(x - x1)

Using the point (0, 6):

y - 6 = (-3/4)(x - 0)

y - 6 = (-3/4)x

In standard form:

To convert the equation to standard form, we can manipulate the equation to have the form Ax + By = C, where A, B, and C are constants.

y - 6 = (-3/4)x

Multiply both sides by 4 to eliminate the fraction:

4(y - 6) = -3x

4y - 24 = -3x

Rearrange the equation to have x and y on the same side and a constant on the other side:

3x + 4y = 24

This is the equation in standard form.

The solution of the given inequality is x < 0  or x > 6. [ And the Graph is given below]

It is quite similar to graphing linear equations to draw inequalities. Two further steps must be taken while concentrating on the inequality sign.

When you graph linear inequalities, you must perform two more steps i.e Choosing between a solid borderline and a dashed boundary line will be the first stage.

We can identify the boundary line with the inequality symbol.

We use a dotted boundary line if the inequality symbol is greater than or less than. This indicates that the answers are not part of the borderline.

We will use a solid line to denote that the solutions are included on the boundary line if the inequality symbol is greater than or equal to or less than or equal to.

Here we have

3 |x - 3| > 9    

Divide by 3 into both sides

=> [ 3|x - 3| ]/3 > 9/3

=> |x - 3| > 3  

As we know

=> |x - 3| > 3    

=>  (x - 3) < -3  or  (x - 3) > 3  

=>   x < 0         or    x > 6

The exact value of the area under the graph of f(x) over the interval [a,b] is False.

If f(x) is a constant function, meaning it has the same value for all x, then the graph of f(x) over the interval [a, b] will be a horizontal line.

The area under a constant function over any interval is simply the product of the constant value and the width of the interval.

However, the formula for the area of a rectangle is not applicable in this case because the graph of a constant function does not form a rectangle.

The area under a constant function is a rectangle only when the function is a constant height (y-value) over the entire interval, which is not the case for arbitrary constant functions.

To compute the exact value of the area under the graph of f(x) over the interval [a, b] when f(x) is a constant, you simply need to multiply the constant value by the width of the interval, which is (b - a).

Therefore, the probability that they find enough subjects for their study is 0.0104

The number of newborns tested is 731. It is believed that 4% of children have a gene that may be linked to juvenile diabetes. The researchers are hoping to have 24 children with the gene for their study. We are required to calculate the probability that they find enough subjects for their study.

Let X be the number of newborns who have the gene of diabetes. As per the given information, the probability of having a gene of diabetes is 4%, i.e.

P(X=1) = 0.04P(X=0) = 1-0.04 = 0.96

We have to find the probability of having 24 or more newborns out of 731 with the gene of diabetes.

So, we can use the Binomial distribution here:

P(X≥24) = 1 - P(X<24)P(X<24) = P(X=0) + P(X=1) + P(X=2) + .....+

P(X=23)P(X<24) = ∑P(X=0 to 23)

Now we can solve this equation to find the probability of having 24 or more newborns out of 731 with the gene of diabetes as follows;

P(X<24) = ∑P(X=0 to 23) =

P(X=0) + P(X=1) + P(X=2) + .....+ P(X=23)P(X<24)

= 0.96^731 + (731C1) (0.04) (0.96)^730 + (731C2) (0.04^2) (0.96)^729 +..... + (731C23) (0.04)^23 (0.96)^708P(X<24) = 0.9896

Now we can find the probability of having 24 or more newborns out of 731 with the gene of diabetes as;

P(X≥24) = 1 - P(X<24)P(X≥24) = 1 - 0.9896 = 0.0104

The probability that the researchers will find enough subjects for their study is 0.0104 or 1.04%.

Therefore, the probability that they find enough subjects for their study is 0.0104 (rounded to three decimal places).

Answer:

Step-by-step explanation:

To find the derivative of the function f(x), we need to take the derivative of the natural logarithm (ln) of the function. We can do this by using the chain rule, which states that the derivative of the composition of two functions is equal to the derivative of the outer function times the derivative of the inner function.

The derivative of the outer function (ln) is 1/f(x), and the derivative of the inner function (14 - e-2x) is -2e-2x. So the derivative of f(x) is:

f'(x) = 1/f(x) × (-2e-2x)

f'(x) = 1/(ln(14 - e-2x)) × (-2e-2x)

f'(x) = -2e-2x/(14 - e-2x)

The angle of depression is the angle between the horizontal line and the  observation line of the object from the horizontal line.

Given is that Jack is one side of a 200 foot wide canyon and Jill is on the other side. Jack and Jill can both see the trail guide at angle of depression of 50 degrees.

From the figure, we can write -

tan (50) = OB/OC

OB = OC tan(50)                                   ......... { 1 }

and

tan (50) = OB/OA

OB = OA tan (50)                                  ......... { 2 }

Equation { 1 } and { 2 } -

OC tan(50) = OA tan(50)

OC = OA                                                   ...... { 3 }

Now -

AC = AO + OC

2OA = AC

2OA = 200

OA = 100 ft

The function checks if the result for the current inputs has already been computed and stored in the `memo` cache. If so, it returns the cached result, otherwise it calculates the result using the recursive definition of the Bessel polynomials and stores the result in the `memo` cache for future use.

Memoization is a technique where we store the results of expensive function calls and return the cached result when the same inputs occur again. Here's a recursive function that uses memoization to calculate the n-th Bessel polynomial at x:

```
memo = {}  # Memoization cache

def B(n, x):
   if n == 0:
       return 1
   elif n == 1:
       return x + 1
   elif (n, x) in memo:
       return memo[(n, x)]
   else:
       result = (2 * n - 1) * x * B(n - 1, x) + B(n - 2, x)
       memo[(n, x)] = result
       return result
```

The function checks if the result for the current inputs has already been computed and stored in the `memo` cache. If so, it returns the cached result, otherwise it calculates the result using the recursive definition of the Bessel polynomials and stores the result in the `memo` cache for future use. This approach avoids redundant calculations and can significantly speed up the computation of Bessel polynomials for large values of n.
