What is the value of a?

Answer:

150pi

Step-by-step explanation:

The formula for the volume of a cone is one-third the volume of a cylinder.

It is   [tex]V=\frac{1}{3} Bh[/tex]   where B is the area of the circle base and h is the height of the cone.

To find the base of the cone, use the formula for the area of a circle. So, the radius is 5. So, the area of the base is pi × radius².

[tex]5^{2} =25[/tex]

[tex]\frac{1}{3}[/tex] × 25pi × 18 = 150pi

Step-by-step explanation:

The probability that three of the children have sickle cell anemia and three of the children are healthy 13.2%.

Sickle cell anemia is an autosomal recessive condition, the trait is only visible in the homozygous state.

The parents are heterozygous( Aa × Aa), and the progeny (AA, Aa, Aa, and aa) have a normal probability of 3/4 and an affected probability of 1/4.

The binomial theorem can be used to calculate the probability of a normal and affected child:

Probability =  n! / x! ( n! - x!) × pˣqⁿ⁻ˣ.

Here, n is the total children 6,

Let 'x' be the normal child

Then, n! - x! is the affected child.

Let 'p' is the normal child probability (= 3/4) and

Then, 'q' is affected child probability (= 1/4).

Substituting the values in the formula;

probability = (6!/3!×3!)×(3/4)³×(1/4)³

on solving

probability = 0.1318

probability = 13.18%

probability = 13.2% (approximately)

Therefore,  the binomial theorem to determine the probability that three of the children have sickle cell anemia and three of the children are healthy is 13.2%.

The perimeter of rectangle is expressed as;

P = 2( l + w )

Given the data in the question;

Let x represent the width of the rectangular base.

Plug these values into the equation above.

P = 2( l + w )

810 = 2( (3x-75) + x )

810 = 6x - 150 + 2x

810 = 8x - 150

8x = 810 + 150

8x = 960

x = 960/8

x = 120

In  linear equation, the distance of the flowerbed from the hive is 2250 feet.

What in mathematics is a linear equation?

Let , the distance of the flowerbed from the hive is  feet.

The bee flies 20 feet per second directly to a flowerbed from its hive and flies directly back to the hive at 12 feet per second.

      time =   distance / speed

So, the time taken by the bee to reach the flowerbed x/20 seconds and the time taken to fly back to the hive = x/12  seconds.

The bee stays at the flowerbed for 15 minutes or (15×60)seconds or 900 seconds and it is away from the hive for a total of 20 minutes or (20×60)seconds or 1200 seconds.

So, the equation will be

 x/20 + x/12 + 900 = 1200

3x + 5x / 60 = 300

8x  = 300 * 60

x = 2250

Thus, the distance of the flowerbed from the hive is 2250 feet.

So, at this rate the total number of bushels sold in five days will be = (119÷8)×5

Performing multiplication and division on Right Hand Side of the equation to find the number of bushels

Total number of bushels sold in five days will be = 74.375

So, after five days of sale, the available number of bushels are 160 - 74.375

The dimension of the base of the rectangular building is 340 x 135ft.

Perimeter of Rectangle:

The definition of perimeter of the rectangle is the total length or distance of its boundary on all sides.

The general formula to calculate the Perimeter of a rectangle is,

P = 2(l + w)

Where,

l represents the length of the rectangle

w represents the width of the rectangle.

Given,

The building in a city has a rectangular base. the length of the base measures 65ft less than three times the width.

The perimeter of this base is 910ft.

Now, we need to find the dimensions of the rectangular base.

According to the given details, the values of

L = 3W - 65

W = W

P = 910

Apply the values on the formula, then we get,

=> 910 = 2 * (L + W)

=> 910/2 = (L + W)

=> 455 = L + W

Apply the value of L,

=> 475 = 3W - 65 + W

=> 475 + 65 = 4W

=> 540 = 4W

=> 540/4 = W

=> W = 135

Apply the value of W as 135, in order to get the value of L,

=> L = 3*135 - 65

=> L = 405

=> L = 340

Therefore, the dimension of the rectangular base is 340 x 135 ft.

Using algebraic expressions and equations, Carol should buy 2 t-shirts and 9 sweatshirts.

We can set up an algebraic expressions and equations to determine how many of each type of gift should Carol buy.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

1. Write an equation for the total number of members.

x + y = 11   (equation 1)

where x is the number of members who will get t-shirt

y is the number of members who will get sweatshirt

2. If each t-shirt costs $5 and each sweatshirt costs $12, write an equation for the total amount spent buying the gift.

$5(x) + $12(y) = $118     (equation 2)

where x is the number of members who will get t-shirt

y is the number of members who will get sweatshirt

3. Rewrite equation 1 as an equation of y in terms of x.

x + y = 11   (equation 1)

y = 11 - x

4 . Plug in the expression for y in equation 2 and solve for x.

$5(x) + $12(y) = $118     (equation 2)

5x + 12(11 - x) = 118

5x + 132 - 12x = 118

-7x = -14

x = 2

5. Substitute the value of x in either equation 1 or 2 and solve for x.

x + y = 11   (equation 1)

2 + y = 11

y = 11 - 2

y = 9

Hence, Carol should buy 2 t-shirts and 9 sweatshirts.

Checking,

2 + 9 = 11

Each member will receive a gift.

2($5) + 9($12) =$118

Carol will be spending $118 for the gifts.

The specified value of n for trapezoidal rule, the midpoint rule, and simpson's rule is 10.36 , 10.72 and 10.52.

Trapezoidal Rule: In Calculus, “Trapezoidal Rule” is one of the important integration rules. The name trapezoidal is because when the area under the curve is evaluated, then the total area is divided into small trapezoids instead of rectangles. This rule is used for approximating the definite integrals where it uses the linear approximations of the functions.

The trapezoidal rule is mostly used in the numerical analysis process. To evaluate the definite integrals, we can also use Riemann Sums, where we use small rectangles to evaluate the area under the curve.

Midpoint rule : In mathematics, the midpoint rule, also known as the midpoint Riemann sum or midpoint method, is a method of estimating the integral of a function or the area under a curve by dividing the area into rectangles of equal width. The midpoint rule formula is. The midpoint method formula works by summing the areas of each of the rectangles to produce an estimate for the area under a curve.

Simpson's Rule: Simpson's rule is used to find the value of a definite integral (that is of the form b∫ₐ f(x) dx) by approximating the area under the graph of the function f(x). While using the Riemann sum, we calculate the area under a curve (a definite integral) by dividing the area under the curve into rectangles whereas while using Simpson's rule, we evaluate the area under a curve is by dividing the total area into parabolas. Simpson's rule is also known as Simpson's 1/3 rule (which is pronounced as Simpson's one-third rule).

Now,

a=1,b=4,Δx =(b-a)/n =3/6 =1/2

∫4√(ln(x)) dx =((1/2) /2)[4√(ln(1))  +2*[4√(ln(1.5)) +4√(ln(2)) +4√(ln(2.5)) +4√(ln(3)) +4√(ln(3.5))] +4√(ln(4))]

∫4√(ln(x)) dx =10.365336

midpoint rule :

∫4√(ln(x)) dx =(Δx)[f(1.25)+f(1.75)+f(2.25)+f(2.75)+f(3.25)+f(3.75)]]
