The domain and the range of the functions is real numbers. Hence, option A is correct.

We need to determine the domain and range of the function  [tex]\bold{f(x)=-35x^3}[/tex].

Let us define the domain and the range of the function:

Domain:

When all the possible values of an independent variable for which we get the real value of a dependent variable then the values of the independent variables is called domain of the function.

Range:

All the possible values of the function is called the range of the function. Range is the sub-set of co-domain.

Now,

For the given function [tex]f(x)=-35x^3[/tex].

No value of x can restrict the above function hence its domain is real number that is [tex](-\infty, +\infty)[/tex].

And, range of the function is also the same [tex](-\infty, +\infty)[/tex].

Thus, the domain and the range of the functions is real numbers. Hence, option A is correct.

The domain and range of the cubic function f(x) = -35x^3 are both all real numbers, because there are no restrictions on x and the function's output covers all real values.

The function described is f(x) = −35x^3. The domain of a polynomial function, which includes cubic functions like this one, is all real numbers because there are no restrictions on the values that x can take. Therefore, the domain is (−∞, ∞). Since the leading coefficient of the cubic term is negative, the ends of the graph will go towards negative infinity as x goes to positive and negative infinity. Therefore, the range of the function is also all real numbers, which we write as (−∞, ∞).

Answer:

No Solution

Step-by-step explanation:

4x-2y=8

y=2x+1

Make the first equation into where it says y=.

-2y=-4x+8

y=2x-4

Substitute either equation into the other as y=.

2x+1=2x-4   or    2x-4=2x+1

Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.

2x-2x=-1-4    or    2x-2x=4+1

0=-5                     0=5

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.

Answer:

The value of A in the given graph of the equation is 1

That is A=1

Step-by-step explanation:

Given graph of the equation is Ax+2y=-2

Given that the equation of line Ax+2y=-2 passes through the point (2,-2)

Let (x,y) br the point (2,-2)

Therefore we have that

A(2)+2(-2)=-2

2A-4=-2

2A-4+2=-2+2

2A-2=0

2A=2

[tex]A=\frac{2}{2}[/tex]

Therefore A=1

Therefore the value of A in the given graph of the equation is 1

Answer:

When solving equations you goal is to get x by itself so

18-6.3x=49.5 (first step would be to minus 18 from each side)

-6.3x=31.5 (18-18=0, 49.5-18=31.5) (now you want to divide each side by -6.3)

x=-5 (-6.3/-6.3=1, 31.5/-6.3=-5)

Your final answer is

x=-5

Question:

What is the numerator of the simplified sum?

x/x^2 +3x+2 + 3/x+1

Answer & Step-by-step explanation:

The given equation is as follows.

       \frac{x}{x^{2}+3x+2} + \frac{3}{x+1}

Taking L.C.M, the equation will become as follows.

      \frac{x(x+1)+ 3(x^{2}+3x+2)}{(x^{2}+3x+2)(x+1)}  ........ (1)

Factorize the equation x^{2}+3x+2 in the denominator as follows.

        x^{2}+3x+2

      =  x^{2} + 2x + x + 2  

      = x(x+2) + 1(x + 2)  

      = (x+1)(x+2) ........ (2)

Put the factors in equation (2) in to equation (1), then the equation will become as follows.

     \frac{x(x+1)+ 3(x^{2}+3x+2)}{(x^{2}+3x+2)(x+1)}

    = \frac{x^{2}+x +3x^{2}+9x+6)}{(x+1)(x+2)(x+1)}

    = \frac{4x^{2}+10x+6}{(x+1)^{2}(x+2)}

Now, factorize the numerator as follows.

      \frac{4x^{2}+10x+6}{(x+1)^{2}(x+2)}

   = \frac{4x^{2}+4x+6x+6}{(x+1)^{2}(x+2)}

   = \frac{4x(x+1) + 6(x+1)}{(x+1)^{2}(x+2)}

   = \frac{(4x+6)(x+1)}{(x+1)^{2}(x+2)}

Cancelling (x+1) from both numerator and denominator. Then the equation will be written as follows.

      \frac{(4x+6)(x+1)}{(x+1)^{2}(x+2)}

    = \frac{(4x+6)}{(x+1)(x+2)}

The numerator of simplified sum is (4x+6).

Answer:

the answer would be 5w-20 after distribution

Answer: 5w + (-20)

Step-by-step explanation: So let's simplify this problem using the distributive property. The first thing we want to do is change the minus to plus a negative.

Now we can distribute or multiply the 5 by each of the terms inside the set of parentheses.

So we get 5(w) + 5(-4) and this simplifies to 5w + (-20).

The premium of the policy is approximately $64,198.32.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the premium of the policy, we need to take into account the probability of the person dying in the next 20 years and the payout of the policy.

Let P be the probability of the person dying in the next 20 years, and let A be the administrative costs of the policy.

Then the expected value of the payout of the policy is:

E(payout) = P x $60,000

And the expected value of the cost of the policy (including administrative costs) is:

E(cost) = P x premium + A

We want to find the premium of the policy, so we can rearrange this equation to solve for the premium:

premium = (E(cost) - A) / P

Substituting the given values, we get:

P = 0.072698

A = $75

E(payout)

= P x $60,000

= 0.072698 x $60,000

= $4,361.88

Now we need to calculate the expected value of the cost of the policy.

The cost of the policy includes both the payout (if the person dies) and the administrative costs (whether or not the person dies).

So we can write:

E(cost) = E(payout) + A x (1 - P)

where (1 - P) is the probability that the person will not die in the next 20 years.

Substituting the given values, we get:

E(cost) = $4,361.88 + $75 x (1 - 0.072698) = $4,746.88

Finally, we can calculate the premium of the policy:

premium = ($4,746.88 - $75) / 0.072698 = $64,198.32

Therefore,

The premium of the policy is approximately $64,198.32.

The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.

Step-by-step explanation:

Let,

x be the number of candles sold by Julio in first week.

According to given statement;

Candles sold in first week = x

He sold twice the number of candles the second week as he did the first week.

Candles sold in second week = 2x

In the third week, Julio sold 4 less than the number he sold the first week.

Candles sold in third week = x-4

Total candles sold = First week + Second week + Third week

Total candles sold = x+2x+(x-4)

The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.

an example of an equivalent inequality is

5+(-m) is greater than or equal to 20

Answer: B. y = 2/3 x - 13/3

Step-by-step explanation:

two lines are said to be parallel if they have the same slope.

To find the slope of line K we will use the formula fro calculating slope which is :

m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]x_{1}[/tex] = 2

[tex]x_{2}[/tex] = 8

[tex]y_{1}[/tex] = -3

[tex]y_{2}[/tex] = 1

substituting into the values into the formula , we have :

m = [tex]\frac{1-(-3)}{8-2}[/tex]

m = [tex]\frac{4}{6}[/tex]

m = [tex]\frac{2}{3}[/tex]

Therefore : the slope of line K = [tex]\frac{2}{3}[/tex] , this means that any line that will be parallel to K must have a gradient of [tex]\frac{2}{3}[/tex].

The only line that has a gradient of [tex]\frac{2}{3}[/tex] is the line y = 2/3x - 13/ 3 ,this means that the line is parallel to Line K

Answer:

d^2 - π(d/2)^2

Step-by-step explanation:

Since the diameter of the circle is equal to the side of a square (d), that means that we have a circle inscribed in square.

If we draw a square and inscribe a circle in it, all parts of the square outside the circle will be waste, in this particular case.

If we want to find the area of the wasted material we need to subtract the area of the circle from the area of the square.

Area of the circle is:

P1 = πr^2, r being the radius

Since radius is half the diameter, that means that:

P1 = π • (d/2)^2

Area of the square whose side is d is:

P2 = d^2

So, the area of wasted material is:

P = P2 - P1

P = d^2 - π(d/2)^2

Step-by-step explanation:

The average speed is 135.26 miles per hour

Solution:

Given that, woman traveled 2445.9 miles in 18 hours five minutes

To find: Average speed of her flight in miles per hour

Let us first convert 18 hours 5 minutes to hours

We know that,

[tex]1 \text{ minute } = \frac{1}{60} \text{ hour }[/tex]

Therefore,

[tex]5 \text{ minute } = \frac{5}{60} \text{ hour } = 0.083 \text{ hour }[/tex]

Thus we get,

18 hours five minutes = 18 hour + 0.083 hour = 18.083 hour

Given that, distance = 2445.9 miles

Average speed is given by formula:

[tex]Average\ speed = \frac{distance}{time}\\\\Average\ speed = \frac{2445.9}{18.083}\\\\Average\ speed = 135.26[/tex]

Thus average speed is 135.26 miles per hour

4 : 2

Step-by-step explanation:

The two triangles Δ ABC and Δ A'B'C' are similar.

Here, ∠ A = ∠ A' = 104°, ∠ B = ∠ B' = 50° and ∠ C = ∠ C' = 26°.

Now, the length of AB and the length of A'B' are 4 cm and 2 cm respectively.
