(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number

(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.

Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.

The function f(x)=Acosh(Cx)+Bsinh(Cx). I need help determining the value of constant C>0 when the second derivative f''(x)=25(f(x)).

Answers

Answer:

C = 5.

Step-by-step explanation:

First, you need to remember that:

For the function:

h(x) = Sinh(k*x)

We have:

h'(x) = k*Cosh(k*x)

and for the Cosh function:

g(x) = Cosh(k*x)

g'(x) = k*Cosh(k*x).

Now let's go to our problem:

We have f(x) = A*cosh(C*x) + B*Sinh(C*x)

We want to find the value of C such that:

f''(x) = 25*f(x)

So let's derive f(x):

f'(x) = A*C*Sinh(C*x) + B*C*Cosh(C*x)

and again:

f''(x) = A*C*C*Cosh(C*x) + B*C*C*Sinh(C*x)

f''(x) = C^2*(A*cosh(C*x) + B*Sinh(C*x)) = C^2*f(x)

And we wanted to get:

f''(x) = 25*f(x) = C^2*f(x)

then:

25 = C^2

√25 = C

And because we know that C > 0, we take the positive solution of the square root, then:

C = 5

Step-by-step explanation:

Hi,

Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.

One of the legs is equal to 40 feet

So, tan(b) = 40/x

tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)

0.8 = 40/x

0.8x = 40

x = 50ft

Answer:

he parameter h is the extremal point of the quadratic. The extremum happens when x=h, when the function (x−h)2 is minimized (or −(x−h)2 maximized). So the reason for the minus sign is because x=h is equivalent to x−h=0.

A truck can be rented from Company A for ​$90 a day plus ​$0.50 per mile. Company B charges ​$40 a day plus ​$0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

Tthe number of miles in a day at which the rental costs for Company A and Company B are the same is    500 miles

The truck is driven X miles per day

Charges of company A will be = 90+0.5x

Charges of company B will be =40+0.60x

We need to find the value of X when charges of both companies are same

90+0.5X= 40+0.60x

   90-40 = 0.60x-0,50x

            50 = 0.10x

                    50/0.10= X

                             X= 500

The charges of both companies will be same if truck is driven 500 miles per day

Help pleaseee

Answers

Answer:

AC = 12.4

Theta = 75.96 degrees

Alpha = 14.04 degrees

Step-by-step explanation:

Mathematically, the angle at each edge of the rectangle is 90 degrees

So, we can see a right triangle ABC

Where AC is its hypotenuse

Mathematically, the square of the hypotenuse equals the sum of the squares of the two other sides

That will be;

3^2 + 12^2 = 9 + 144 = 153

AC = √153

AC = 12.4

We need to use the appropriate trigonometric ratio to get the value of alpha and theta

For theta;

Its opposite side is 3 while its adjacent is 12

The trigonometric ratio to use is the tan

so;

tan theta= 3/12

tan theta = 1/4

theta = tan^-1 0.25

theta = 14.04

Now for alpha, since we have a right triangle

theta will be 90-14.04

theta = 75.96

The measure of AC to the nearest hundredth is 12.37

SOH CAH TOA identity

From the given figure, we have the following parameters

Using the theorem;

tan a = 12/3

tan a = 4

a = 75.96

theta = 90 - 75.96

theta = 14.03

For the length of AC, we will use the Pythagoras theorem

AC = √3² + 12²

AC = √9+144
AC = 12.37

Hence the measure of AC to the nearest hundredth is 12.37

Find the derivative of f(x) = -4x2 + 11x at x = 10.
a) 19.5
b) -69
c) 30
d) -300

Answers

Answer:

-69 (Answer b)

Step-by-step explanation:

Apply the power rule for differentiation:

(d/dx){-4x^2 + 11x} = -8x + 11

Now substute 10 for x:

f '(x) = -8(10) + 11 = -80 + 11 = -69 (Answer b)

Answer:

b

Step-by-step explanation:

Using the power rule to differentiate each term

Given

f(x) = - 4x² + 11x , then

f'(x) = - 8x + 11

At x = 10

f'(10) = - 8(10) + 11 = - 80 + 11 = - 69 → b

Why are humans responsible for many invasive species?6. What are the three main roles of an ecosystem?7. What is the purpose of a decomposer in an ecosystem?An ecosystem is made up of all the living and nonliving things in an area. The living parts include plants, animals and insects. The nonliving parts include water, rocks, soil and sand. Swamps,prairies, oceans and forests are all examples of ecosystems.There are usually many different kinds of life in a single ecosystem. A grassland ecosystem, for example, contains much more than just grass. It includes other plants, mammals, insects and earthworms. It also includes many tiny living things in the soil.Three Roles For Living Things Each living thing in an ecosystem has a role to play. The three main roles are producer, consumer and decomposer. Green plants are producers. They make their own food through a process called photosynthesis. Animals, including humans, are consumers. They eat, or consume, plants or other animals. By Encyclopaedia Britannica,Bacteria and other living things that cause decay are decomposers. Decomposers break down the waste products and dead tissue of plants and animals. They return nutrients to the soil. These nutrients help new plants grow. Producers, consumers and decomposers depend on one another and provide nutrients for one another.This is called a food chain.Feeding Levels A food chain describes the order in which matter and energy move through the feeding levels of an ecosystem. The levels of a food chain are basically the same across all ecosystems. The first level is the producers. After that is the consumers. Sometimes consumers are further divided into primary consumers, secondary consumers and tertiary consumers. The final link in all food chains is the decomposers. The decomposers break down dead organisms and natural waste.The consumers at the top feeding level of a food chain are called top predators. They have no predators hunting and trying to eat them. Instead, their population size is controlled through competition. They have to compete with one another for food and other resources.Energy FlowThe main source of energy in almost all ecosystems is the sun's energy. As energy moves through the ecosystem, much of it is lost at each feeding level. Itescapes as heat. That is the main reason why few food chains have more than five feeding levels. Diagrams called energy pyramids are used to show the flow of energy from one feeding level to the next in a food chain. Most ecosystems have more than one food chain. Food chains overlap. They connect to form a food web.Recycling Nutrients Many nutrients are constantly cycling through an ecosystem. These include water, carbon and nitrogen. A nutrient is something that helps living things grow.Nutrients from soil enter into plant tissues. When consumers eat the plants, the nutrients enter the consumers' tissues. Consumers that are eaten transfer the nutrients on to the predator at the next feeding level. Consumers that are not eaten die and transfer nutrients in their decaying tissues to the decomposers that feed on them. The decomposers recycle these nutrients back into the ecosystem. They transfer the nutrients back into the soil and air, where the nutrients become available to producers.A Delicate Balancean ecosystem's health depends on a delicate balance. This balance must exist between all of the members of the ecosystem, and their surrounding environment. If something disturbs the balance,the ecosystem and all its members might suffer. Natural things that can disturb ecosystems include a changing climate and natural disasters.Human activities that can disturb ecosystems include polluting and clearing land for farms or buildings.Humans also are responsible for many invasive species. An invasive species is a living thing that spreads through an ecosystem where it did not exist before. Invasive species can threaten the plants and animals that originally made up the ecosystem. For example, Burmese pythons were brought to Florida as pets. Some pythons escaped and began reproducing in the wild. Their skill at hunting has decreased the number of wood rats and storks in the area. This upset the balance of the natural ecosystem. please help i dont get it :( A student draws two parabolas on graph paper. Both parabolas cross the x-axis at (4, 0) and (6, 0).
