Mathematicians use graphs to logically chart or illustrate claims rather than values in an interesting visual way. Usually, a graph point shows the connection between two or more objects. A graph is a particular kind of non-linear railway assembly composed of nodes and lines. The nodes, also known as the borders, should be joined together with glue. The node numbers in this network included 1, 2, 3, and 5, while the edge numbers included 1, 2, 3, and 4, along with (2.5), (3.5), (4.5), but also (4.5). (4.5).

Here,

Plotting a few important spots will help us later when we sketch the graph of f(t) = 5 cos(t).

Since the function has a phase of 2, we can concentrate on the range from 3/2 to 3/2. We possess

=> f(−3/2) = 5 cos(−3/2) ≈ 4.515

=> f(−π) = 5 cos(−π) = −5

=> f(−1/2) = 5 cos(−1/2) ≈ 4.045

=> f(0) = 5 cos(0) = 5

=> f(1/2) = 5 cos(1/2) ≈ 4.045

=> f(π) = 5 cos(π) = −5

=> f(3/2) = 5 cos(3/2) ≈ 4.515

Using these coordinates, we can create the following f(t) graph:

With maximum positions at t = /2 and t = /2, and minimum points at t = 3/2, t = 1/2, t = 1/2, and t = 3/2,

Answer:

The result of subtracting 3 km 500 m from 10 km is 6500 m (Or expressed in kilometers: 6.5 km).

Step-by-step explanation:

Hi,

We need to convert both measurements to the same unit (either km or meters) and then subtract:

Reminder:

1 km = 1000 m

=> 10 km = 10 * 1000 = 10000 m

=> 3 km 500 m = 3 * 1000 + 500 = 3500 m

Now we can subtract:

10000 m - 3500 m = 6500 m

The result of subtracting 3 km 500 m from 10 km is 6500 m (Or expressed in kilometers: 6.5 km).

Venn diagrams are the diagrams used to visually describe sets, relationships between sets, and operations carried out on them. John Venn (1834–1883) invented the Venn diagram, which makes use of circles (overlapping, intersecting, and non–intersecting) to show the relationship between sets. A Venn diagram can also be referred to as a set diagram or a logic diagram that illustrates various set operations including the intersection, union, and difference of sets. Subsets of a set are also represented using it.

A subset of whole numbers, which is a subset of integers, is a collection of natural numbers, as an example. The Venn diagram can demonstrate the relationship between the sets of whole numbers, integers, and natural numbers.

Using the chain rule, the value for dz/dt is obtained as [tex]dz/dt = 2(2t + (4 - t^2)e^{(4-t^2)}) ((1 - t)e^{(4-t^2)})[/tex].

What is chain rule?

The chain rule is the formula used to determine the derivative of a composite function, such as cos 2x, log 2x, etc. Another name for it is the composite function rule. Only composite functions are subject to the chain rule.

To find dz/dt using the chain rule, we need to differentiate each term of z with respect to t, then multiply by the derivative of the inner function with respect to t.

First, we have -

x = 2t

Taking the derivative with respect to t, we get -

dx/dt = 2

Next, we have -

y = 4 - t²

Taking the derivative with respect to t, we get -

dy/dt = -2t

Using the chain rule, we have -

[tex]dz/dt = (x + y)e^y \times (\frac{dx}{dt} + \frac{dy}{dt}e^y)[/tex]

Substituting x and y into this equation, we get -

[tex]dz/dt = (2t + (4-t^2))e^{(4-t^2)} \times ((2 - 2t) e^{(4-t^2)})[/tex]

Simplifying this expression, we get -

[tex]dz/dt = 2(2t + (4 - t^2)e^{(4-t^2)}) ((1 - t)e^{(4-t^2)})[/tex]

The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years IS 0.528.

The binomial probability formula is used to calculate the probability of getting exactly k successes in n independent trials, where each trial has only two possible outcomes (success or failure) and the probability of success is denoted as p. The formula is:

Here we have  

39.6​% of consumers believe that cash will be obsolete in the next 20 years.

Let p be the probability that a consumer believes that cash will be obsolete

=> p = 39.6% or 0.396.

Then, the probability that a consumer does not believe that cash will be obsolete is q = 1 - p = 0.604.  

We need to find the probability that less than 3 of the selected consumers believe that cash will be obsolete.

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

Using the binomial probability formula, we have:

[tex]P(X = k) = C(n,k) \times p^k\times q^{(n-k)[/tex]

=> P(X = 0) = C(6, 0) × (0.396)⁰ × (0.604)⁶ = 0.048

=> P(X = 1) = C(6, 1) × (0.396)¹ × (0.604)⁵ = 0.18

=> P(X = 1) = C(6, 2) × (0.396)² × (0.604)⁴ = 0.3

P(X < 3) = 0.048 + 0.18 + 0.3 = 0.528

Answer:

Let's break down the cost and revenue for Jack's toy car sales:

The cost to Jack is the website fee of $30.

The revenue for Jack is the number of toy cars he sells (c) multiplied by the selling price of each toy car, which is $4 per toy car.

To make a profit of at least $50, Jack's revenue must be at least $80 ($30 website fee + $50 profit). Therefore, we can set up the following inequality:

4c - 30 ≥ 50

Solving for c, we get:

4c ≥ 80

c ≥ 20

So, Jack must sell at least 20 toy cars to make a profit of at least $50. The correct answer is option B: 34c ≥ 50.

Answer:

B

Step-by-step explanation:

34c < 50 = 136 (136 is greater than 50 wrong sign) x

B 34c > 50 = 136 (136 is greater than right sign)

C 4c-30 > 50 = -14 > 50 (wrong)

We have two shapes:

One Triangle and One Rectangle

Area of Triangle: A = 1/2*B*H

Area of Rectangle: A = L*W

Area of Triangle:

A = 1/2 * 6 * 7

A = 3 * 7

A = 21 m^2

Area of Rectangle:

A = 18 * 14

A = 252 m^2

Now add Area of Triangle and Area of Rectangle to get the whole area of the shape.

A = 21 + 252 = 273 m^2

Answer:

Step-by-step explanation:

To solve this system of equations by substitution, we need to solve one of the equations for one of the variables, and then substitute that expression into the other equation. Here's how we can do that:

y = x - 6 (equation 1)

We can solve equation 1 for y by adding 9x to both sides:

9x + y = x - 6 + 9x

y = -8x - 6 (equation 2)

Now we can substitute equation 2 into equation 3 and solve for x:

-8x - 6 = -9x + 14

Adding 8x to both sides, we get:

y = -x + 8

Subtracting 14 from both sides, we get:

-x = -6

Dividing both sides by -1, we get:

x = 6

Now that we have found the value of x, we can substitute it back into equation 1 or equation 2 to find the value of y. Let's use equation 2:

y = -8(6) - 6

y = -54

Therefore, the solution to the system of equations is:

x = 6, y = -54

We can check this by substituting these values into the original equations:

-9(6) + 14 = -54

6 - 6 = 0

So the values of x and y satisfy both equations, and therefore they are the solution to the system.

14 ft³ is equal to 104,720 fluid ounces.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

We have to convert 14 ft³ to fluid ounces

we need to use the conversion factor: 1 ft³ = 7,480 fluid ounces

Multiplying both sides by 14, we get:

14 ft³ = 14 x 7,480 fluid ounces

= 104,720 fluid ounces

Therefore, 14 ft³ is equal to 104,720 fluid ounces.

The slope of f(x) = x² - x + 2 at x = 3 is 6.

The limit definition of a derivative is given by:

f'(x) = lim(h->0) [f(x+h) - f(x)] / h

To find the slope of f(x) = x² - x + 2 at x = 3, we need to evaluate this expression at x = 3.

f'(3) = lim(h->0) [f(3+h) - f(3)] / h

f'(3) = lim(h->0) [(3+h)² - (3+h) + 2 - (3² - 3 + 2)] / h

f'(3) = lim(h->0) [(9 + 6h + h² - 3 - h + 2 - 9 + 3 - 2)] / h

f'(3) = lim(h->0) (6h + h²) / h

f'(3) = lim(h->0) (h(6 + h)) / h

f'(3) = lim(h->0) (6 + h)

Now we can evaluate the limit by plugging in h = 0:

f'(3) = 6 + 0 = 6

Answer:

Step-by-step explanation:

Let's call the length of the pen perpendicular to the barn "w", and the length parallel to the barn "l".

The total amount of fencing available is 400 feet. The side against the barn will be of length l, and the other two sides will each be of length w. Therefore, the total length of fencing required is:

l + 2w

This length of fencing must equal 400 feet:

l + 2w = 400

We want to maximize the area of the pen. The area of a rectangle is given by:

A = lw

We can use the equation l + 2w = 400 to solve for l:

l = 400 - 2w

Substituting this expression for l into the equation for the area, we get:

A = w(400 - 2w)

Simplifying:

A = 400w - 2w^2

So the equation to model the area of the pen in terms of w is:

A = 400w - 2w^2

Mary's monthly payments will be approximately $117.50.

The total instalment price is the price of the furniture plus the interest charged. Since Mary made a down payment of 15%, the amount that is subject to interest is 85% of the total price. Therefore:

Total price = (100% / 85%) * $750 = $882.35

The interest charged is 6% of the total price over the 8-month payment period. Therefore:

Interest charged = 6% * $882.35 * (8 / 12) = $35.29

The total installment price is the sum of the total price and the interest charged:

Total installment price = $882.35 + $35.29 = $917.64

To find the monthly payments, we can use the formula for the present value of an annuity:

Payment = [tex]\mathrm{PV \times (r / (1 - (1 + r)^{(-n)}))}[/tex]

where PV is the present value (total installment price), r is the interest rate per month (6% / 12 = 0.005), and n is the number of payments (8).

Substituting the values:

Payment = $917.64 × (0.005 / [tex](1 - (1 + 0.005)^{(-8)}[/tex] ≈ $117.50

The value of x in the given arrangement of equilateral triangle and isosceles triangle is 88°

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Given that,

A arrangement which contains,

one equilateral triangle ABE &

one isosceles triangle CDE

It is known that sum of all the angles in each direction is 180°.

ΔAEB is equilateral triangle,

so angle will be of 60°

∠AEB = 60°

And in isosceles triangle,

∠EDC = ∠ECD

∠ADC = 90°

∠ADC = ∠ADE + ∠EDC

90°  =  62°  + ∠EDC

∠EDC  = 28°  = ∠ECD

It is known that sum of all the interior angles of the triangle is 180°.

∠EDC  + ∠ECD + ∠DEC   = 180°

28° + 28° + ∠DEC   = 180°

∠DEC   = 124°

Now sum of all the angles around point E is 360°

∠AED + ∠DEC + ∠BEC + ∠AEB  = 360°

x   +  124°  + x  + 60°  = 360°

2x  = 176°

x = 88°
