Answer:

a) 18

b)248

c) 58

Step-by-step explanation:

The formula is:

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1)d

[tex]a_{n}[/tex]  Is the number at the n term

[tex]a_{1}[/tex] Is the first number in the sequence

n Is the number for the term

d is the common difference.  How much is added each time in the sequence.  In this case, 2.5

Put in the numbers that you know and solve for the unknown.

A:

[tex]a_{8}[/tex] = 0.5 + (8 -1)(2.5)

[tex]a_{8}[/tex]  = 0.5 +(7)(2.5)

[tex]a_{8}[/tex] = 0.5 + 17.5

[tex]a_{8}[/tex] = 18

B:

We follow the same pattern, but we are now looking for [tex]a_{100}[/tex].

[tex]a_{100}[/tex] = 0.5 + (100-1)(2.5)

[tex]a_{100}[/tex] = 0.5 + 247.5

[tex]a_{100}[/tex] = 248

C:

This time we know the value of the number in the sequence, we do not know which term it is.

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1)d  Put in what we know

148 = 0.5 + (n -1)2.5  Distribute the 2.5

148 = 0.5 + 2.5n - 2.5  Combine like terms

148 = 3 + 2.5n  Subtract 3 from both sides of the equation

145 = 2.5n  Divide both sides by 2.5

58 = n

Explanation:

The equation is y = 10x+550

If x = 0, then it leads to y = 550. This is the smallest amount paid, and it's the base fee. Think of it like the fee to get in the door. This is the y intercept of the equation.

On top of this base fee is the $10 per hour fee for utilities. Each time an hour goes by, add on another extra $10. So we attached x to this to reflect what's going on. This is the slope of the equation, aka rate of change.

It might be helpful to compare y = mx+b to y = 10x+550

m = 10 = slope = how things change

b = 550 = y intercept = starting point

----------

Example:

Let's say you rented the barn for 2 hours.

That means x = 2 and 10x = 10*2 = 20 extra dollars is added on top of the base fee of $550

total = 20+550 = 570

This is what the steps could look like when plugging in x = 2

y = 10x+550

y = 10*2 + 550

y = 20 + 550

y = 570

Therefore, renting the barn for x = 2 hours leads to a total cost of y = 570 dollars.

The larger bottle holds a 700ml volume of water.

What is volume?

Two(2) bottles given in the pic are similar(no difference)

Therefore, the volume/cm height of both(2) bottles will proportional

By using the proportionality rule, [tex]\frac{15}{500} =\frac{21}{x}[/tex]

The volume of the box is maximized when a 6 x 6 inch or 10 x 10 inch square is cut from the corners of the rectangular sheet.

Volume of rectangle:

The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.

The formula for Volume of the rectangle is

V = l x b x h

where

l represents the length

b represents the breadth

h represents the height.

Given,

A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box.

Here we need to find the volume of the box is maximized when a square is cut from the corners of the rectangular sheet.

Here we have the following values:

h = x

l = 20 - 2x

b = 12 - 2x.

Here we have to subtract two times of x value because in the question they said that we have to cut a square from it.

Apply the values on the volume formula then we get,

=> V = (20 - 2x) x (12 - 2x) x (x)

=> V = [240 - 40x - 24x + 4x²] x (x)

=> V = [240x - 64x² + 4x³]

Now differentiate:

=> V' =  240 - 64x + 4x²

Simplify and order the equation,

Then we get,

=> V' = x² - 16x + 60

When we factorize the equation then we get,

=> V' = x² - 6x - 10x + 60

Take the common term out of it,

=> V' = x (x-6) -10(x -6)

Therefore, the value of x is, either 6 or 10.

Now you need to look at your solutions.

At x=6, the volume is,

=> V = (20 - 2(6)) x (12 - 2(6)) x (6)

=> V = (20 - 12) x (12 - 12) x 6

=> V = 8  x 0 x 6

=> V = 0

our corner squares devour the entire piece of cardboard and you are left with zero volume; so that solution is a minimum.

Now at the value of x = 10,

The volume is

=> V = (20 - 2(10) x (12 - 2(10)) x (10)

=> V = (20 - 20) x (12 - 20) x 10

=> V = 0 x (-8) x 10

=> V = 0

So, in both cases we have 0 as minimum volume. So, we can take any one of the value to get the maximum out of it.

Step-by-step explanation:

Find the value of t0.05 for a t-distribution with 9 degrees of freedom. round your answer to three decimal places, if necessary.

The circumference of the circle with arc AB as 22 cm and C as the center will be 176 cm.

We are given that:

Length of the shorter arc forming an angle of 45° with the center = 22 cm

AB = 22 cm

C is the center of the circle.

We know that the length of the arc is calculated as:

Length of an Arc = θ × (π / 180) × r

22 = 45 × (3.14 / 180) × r

22 = 0.785 r

r = 22 / 0.785

r = 28.0255

Circumference = 2 π r

Circumference = 2(3.14) (28.0255)

C = 176 cm

Therefore, we get that, the circumference of the circle with arc AB as 22 cm and C as the center will be 176 cm.

The length of a rectangle is 27 inches and the width of a rectangle is 12 inches.

Given that, the length of a rectangle is three more than double the width and the perimeter of a rectangle = 78 inches.

We need to find the dimensions of the rectangle.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Let the width of the rectangle be x.

Then, length=2x+3

Now, perimeter=2(2x+3+x)

⇒ 78=2(3x+3)

⇒ 3x+3= 39

⇒ 3x=36

⇒ x=12 inches

So, width=12 inches and length=2x+3=27 inches

Therefore, the length of a rectangle is 27 inches and the width of a rectangle is 12 inches.

∫dF=F(x,y)=12ax2+bxy+12ℓy2+c=0 is the exact ode.

Specifically, an exact equation is a differential equation that can be solved instantly without the aid of any specialized methods. If the result of a straightforward differentiation, a first-order differential equation (of one variable) is referred to as an exact differential or exact differential. The equation

P(x, y)dy/dx + Q(x, y) = 0,

or in the equivalent alternate notation

P(x, y)dy + Q(x, y)dx = 0,

is exact if

∂P(x, y)/∂x =  ∂Q(x, y)/∂y

In this instance, a function R(x, y) will exist whose partial x-derivative is Q and partial y-derivative is P, and whose equation R(x, y) = c (where c is constant) will implicitly establish a function y that will satisfy the initial differential equation.

An exact ODE is one where the equation can be written as  dF=0  for some  F(x,y). Expanding using chain rule, this means an equation of the form

∂1Fdx+∂2Fdy=0

Now if the second partials of  F  exist and are continuous, they must be equal due to Clairaut. So, given an equation

Mdx+Ndy=0

if we have

∂2M=∂1N

then there is an  F  such that

M=∂1F, N=∂2F

and hence that equation is exact, and the solution is simply

∫dF=0

We have

M=ax+by⇒∂2M=b

N=kx+ℓy⇒∂1N=k

so to be exact, we must have that  b=k .

Then, integrating  M  and  N , we have

F(x,y)=∫Mdx=12ax2+bxy+g(y)

F(x,y)=∫Ndy=bxy+12ℓy2+h(x)

and comparing these two, we can see that

∫dF=F(x,y)=12ax2+bxy+12ℓy2+c=0

Step-by-step explanation:

In this equation, given

f(x) = 3x + 9 and g(x) = 5x -1

So the question is what is the value of f if we put the value of g(x) in f(x)

So to solve the equation we need to replace the value of x in f(x) with g(x)

So it was obtained as below

f(g(x)) = 3(5x-1) + 9

= (15 x - 3) + 9

Step-by-step explanation:

3.5(x+20) = 6 + .75(x + 1)  Multiply the terms inside the parentheses on the left by 3.5 and the parentheses on the left by .75

(3.5)x +(3.5)(20) = 6 + (.75)x +(.75)(1)

3.5x + 70 = 6 + .75x + .75  Combine the 6 and .75 on the right side

3.5x + 70 = 6.75 + .75x  Subtract .75x from both sides of the equation

2.75x + 70 = 6.75  Subtract 70 from both sides of the equation

2.75x  = -63.25  Divide both sides by 2.75

x = -23

We get the surface area as 202 inches² and volume as 168 inches³.

The surface area of a cuboid is given by:

Surface area = 2xy + 2xz + 2yz

Here length = x = 7 inches

Breadth = y = 3 inches

Height = z = 8 inches.

Substituting the values in the formula, we get that:

Surface area = A = 2(7)(3) + 2(7)(8) + 2(3)(8) inches²

A = 42 + 112 + 48 inches²

A = 42 + 160 inches²

A = 202 inches²

Volume of a cuboid is given by :

Volume = xyz

Substituting the values, we get that:

Volume = (7) (3) (8) inches³

Volume = 21 × 8 inches³

Volume = 168 inches³.

Therefore, we get the surface area as 202 inches² and volume as 168 inches³.
