A solid right pyramid has a regular hexagonal base with an area of 5. 2 cm? and a height of h cm.
The volume of the pyramid is V = [tex]\frac{h}{3}(5.2) cm^{3}[/tex] or V = 1.73h [tex]cm^{3}[/tex] .
In mathematics, 'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface. The unit of volume is in cubic units such as m3, cm3, in3 etc.
we know that,
The volume of the pyramid is equal to
V = [tex]\frac{1}{3} BH[/tex]
where,
B is the area of the base and
H is the height of pyramid
In this problem we have,
B = 5.2 [tex]cm^{2}[/tex]
H = h cm
substitute in the formula in V = [tex]\frac{1}{3} BH[/tex] ,
V = [tex]\frac{1}{3}[/tex] × 5.2 × h
V = [tex]\frac{h}{3}(5.2) cm^{3}[/tex]
or
V = 1.73h [tex]cm^{3}[/tex]
Therefore, the volume of the pyramid is V = [tex]\frac{h}{3}(5.2) cm^{3}[/tex] or V = 1.73h [tex]cm^{3}[/tex] .

The volume of the solid right pyramid is given as V= 1/3(b*h) and hence volume(V) is equals to h/3(5.2) cm^3 or 1.73h cm^3
In solid right pyramid volume is given by the product of base of the area and the height of the solid pyramid and it is divided by 3 and volume is defined as the 3-dimensional area covered by the solid right pyramid . so volume is the product of the base of the area and the height and it is divided by 3
So , here "b" is the base of the area
"h" is the height of the solid right pyramid
We have ,base B=5.2 cm^2
height H= h cm
As , Volume is given by the product of the base and height of the right pyramid and it is divided by 3 , we used to solve the volume as
V=1/3 (5.2 * h) cm^3=(h/3)(5.2) cm^3
V=1.73 h cm^3
So, the volume of the solid right pyramid is given by V=h/3 (5.2) cm^3 or V=1.73 h cm^3

the admission fee at an amusement park is $1.50 for children and $4 for adults. on a certain day, 238 people entered the park, and the admission fees collected totaled $632.00. how many children and how many adults were admitted?
There were 128 children and 155 adults.
Let us first set up our system by assigning x and y to mean something. Let x = the number of children and y = the number of adults.
First equation: Children cost $1.50 and Adults cost $4.00. In order to find the amount of money a group of children will cost, we multiply the number of children, x, by 1.5.
This is represented by 1.5x. For adults, who cost 4 dollars to enter, we will use 4y. The total amount of money made on the given day was $632. To get this amount, we must add 1.5x and 4y.
1.5x+4y=632 --------(1)
Second equation: Total amount of people on the given day is 238. To get this number, we must add together x and y, or the number of children and adults.
x + y = 238-----(2)
System of equations:
1.5x+4y=632
x+y = 238
Let's use the substitution of the x variable to solve the system.
x+y=238.
y=238-x
Substitute y = 238 - x into the first equation.
1.5x + 4 (238 - x) =632
1.5x + 952 - 4x = 632
952- 2.5x = 632
-2.5x = -320
x = 128
Substitute x =128 back into y = 238 - x
y = 283-128

at aeropostale, david bought 4 t shirts and 3 pairs of jeans for $181. at the same store, jennifer bought 1 t shirt and 2 pairs of jeans for $94. the t shirts and jeans were the same price in both instances. what is the price of the t shirts?
The price of a t-shirt is $43.50.
Let's call the price of a t-shirt "t" and the price of a pair of jeans "j".
For David:
4t + 3j = 181
For Jennifer:
t + 2j = 94
We can use these two equations to solve for t and j. Subtracting the second equation from the first, we have:
3t + j = 87
Next, we can substitute the second equation into the third equation to eliminate t:
3(t + 2j) = 3 * 94 = 282
Expanding the left side, we have:
3t + 6j = 282
Subtracting j from both sides:
3t + 5j = 282 - j
Combining like terms:
3t + 6j = 282
Subtracting the first equation from the third equation:
2t = 181 - 94
Combining like terms:
2t = 87
Finally, solving for t:
t = 87 / 2 = 43.5

using u = 1 x , we can write h(x) = 1⁄x arctan(t) dt 1 as h(u) = u arctan(t) dt. 1
H(u) = u arctan(x) - (1) arctan(t) dt is obtained by integrating u arctan(t) with respect to t from 1 to x.
The original function h(x) = 1/x arctan(t) dt can be rewritten as h(u) = u arctan(t) dt by substituting u = 1/x. This is accomplished by substituting 1/u for each instance of x in the original equation.
The result of integrating this equation from 1 to x with regard to t is h(u) = u arctan(x) - (1) arctan(t) dt. The integral of u arctan(t) from 1 to x less the integral of arctan(t) from 1 to x can be used to represent this. The integration variable for the first integral is u, while the variable for the second integral is t.
By adding u = 1/x to the equation, the value of h(u) can then be utilised to determine the value of h(x). To accomplish this, all occurrences of u are replaced.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that yummy bakery and oh so good bakery had a contest with these results: yummy sold 9 fewer rolls than twice what oh so good sold. together they sold a total of 639 rolls.
We can write the relation as -
2x - 9 + x = 639
3x - 9 = 639
3x = 648
x = 216
So, we can write -
2x - 9 = 2 x 216 - 9 = 532 - 9 = 523
Therefore, the yummy bakery sold 216 roles and oh so good bakery sold 523 roles.

During a ale, a tore offered a 15% dicount on a bed that originally old for $350. After the ale, the dicounted price of the bed wa marked up by 15%. To the nearet whole number, what percent of the original price wa the price after markup?
The final price is 97.714% of the original price. To the nearest whole number, that's 98%.
Percent After Markup BedLet's call the final price of the bed "x".
First, we'll find the discount price:$350 * 0.15 = $52.50$ discount
So, the discounted price of the bed is $350 - $52.50 = $297.50Next, we'll find the markup amount:$297.50 * 0.15 = $44.63 markup
So, the final price of the bed is $297.50 + $44.63 = $342.13Finally, we'll find the percent increase from the original price:$342.13 / $350 = 0.97714
So, the final price is 97.714% of the original price.
To the nearest whole number, that's 98%.
The method used to solve this problem is applicable to a wide range of similar problems in pricing and discounting, as well as in finance and economics. This method can be used to calculate the final price of an item after applying a discount followed by a markup, or to find the original price of an item given the final price and the discount and markup amounts. The method can also be extended to problems with multiple discounts or markups, as well as problems involving different discount or markup percentages.

show thatf′(x) = 0 at least once for the functionf(x) = 1−ex (e−1) sinπ2xon the interval [0,1]
the function is defined on the interval [0,1], we must have 0 ≤ x ≤ 1. Therefore, the value of x for which[tex]f'(x)=0 is x = 0.[/tex]
To find the value of x for which[tex]f'(x)=0[/tex], we need to differentiate the given function.
[tex]f'(x) = (e-1)(π/2)(ex)(cos(π/2x)) - (sin(π/2x))[/tex]
Now, set [tex]f'(x) = 0[/tex]and solve for x.
[tex](e-1)(π/2)(ex)(cos(π/2x)) - (sin(π/2x)) = 0(e-1)(π/2)(ex) = (sin(π/2x))ex = (sin(π/2x))/(e-1)(π/2)[/tex]
Taking natural log on both sides
[tex]xln(e) = ln(sin(π/2x)) - ln((e-1)(π/2))xln(e) = ln(sin(π/2x)) - ln(e-1) - ln(π/2)x = (ln(sin(π/2x)) - ln(e-1) - ln(π/2))/ln(e)[/tex]
Since the function is defined on the interval [0,1], we must have 0 ≤ x ≤ 1.
Therefore, the value of x for which [tex]f'(x)=0 is x = 0.[/tex]

if |v| = 4 and |w| = 7, what are the smallest and the largest possible values of |v − w|
smallest and the largest possible values of v · w
v and w are vectors, not numbers. v*w indicates the dot product of these vectors and l v l and l w l their magnitudes.
Assuming v and w are vectors with any direction but with definite magnitudes
||v − w|| ≤ ||v|| + ||w|| = 11
and ||v − w|| ≥ ||v|| − ||w||| = 3,
while
|v · w| = ||v||||w|| cos θ ≤ ||v|| · ||w|| = 28,
so −28 ≤ v · w ≤ 28.

find the general solution to enter your answer as . use to denote the arbitrary constant in your answer. tln(t)dr/dt r =5te^4
The general solution to the differential equation d(r)/dt = 5tln(t) is: r = (5/2)t^2ln(t) - 5te^5 + C.
The general solution to the differential equation d(r)/dt = 5tln(t) can be found using the method of integrating factors.
First, we find the integrating factor:
I = e^∫5ln(t)dt = e^(5t - 5)
Next, we multiply both sides of the equation by the integrating factor:
I * d(r)/dt = I * 5tln(t)
Now, we can integrate both sides of the equation:
∫I * d(r)/dt = ∫I * 5tln(t)dt
Using the substitution u = r and du/dt = d(r)/dt, we can simplify the left side of the equation:
du/dt = I * d(r)/dt
And on the right side, we use integration by parts:
∫I * 5tln(t)dt = (5/2)t^2ln(t) - 5te^5 + C
Finally, we can solve for r:
r = (5/2)t^2ln(t) - 5te^5 + C
The general solution to the differential equation d(r)/dt = 5tln(t) is:
r = (5/2)t^2ln(t) - 5te^5 + C.
Note that C is an arbitrary constant and represents the freedom in choosing the initial conditions for the solution.
Therefore, The general solution to the differential equation d(r)/dt = 5tln(t) is: r = (5/2)t^2ln(t) - 5te^5 + C.
