Let f(x)=6−2+2e−0.3x . What is f(−4) ?

Answer:

The correct answer is B) p(x) = -14x - 15

Step-by-step explanation:

To find this, start by writing the function as indicated.

p(x) = r(x) - c(x)

Now input the functions into the appropriate spots.

p(x) = -10x - (4x + 15)

p(x) = -10x - 4x - 15

p(x) = -14x - 15

Answer:

[tex]P(x) =14x-15[/tex]

Step-by-step explanation:

The revenue from selling x necklaces [tex]r(x)= -10x[/tex]

The cost of buying x necklaces is [tex]c(x)= 4x+15[/tex]

The profit from selling x necklaces is [tex]P(x) = r(x)- c(x)[/tex]

Replace r(x) and c(x)

[tex]P(x) =-10x-(4x+15)[/tex]

[tex]P(x) =-10x-4x-15[/tex]

[tex]P(x) =14x-15[/tex]

[tex]5(u + 5) + p(u + 5) = (p + 5)(u + 5)[/tex]

Answer:

x = - 5

Step-by-step explanation:

Given

- 3x + 5 > 17 ( subtract 5 from both sides )

- 3x > 12 ( divide both sides by - 3 )

Remembering to reverse the inequality symbol when dividing/ multiplying by a negative quantity.

x < - 4 ← symbol reversed

The value of x that is in the solution set is x = - 5

Answer:

Group A has 20 students

Group B has 30 students

Step-by-step explanation:

The mean score of 50 students is 54%, so the sum of 50 scores, divided by 50 is 54%.  That means that 50(0.54) = 27 points were scored between the 50 students.

Let x represent the number of students in Group A

Let y represent the number of students in Group B

We have

0.6x + 0.5y = 0.54(50)    (the points scored, times their averages is the total)

and

x + y = 50

Use substitution to solve...solve the second equation for one variable...

x = 50 - y

Now plug that into the first equation...

0.6(50 - y) + 0.5y = 27

     30 - 0.6y + 0.5y = 27

             -0.1y = -3

                   y =  30

So there are 30 students in group B, therefore there are 20 students in group A

Time taken by Julian to complete 24 km trip to Guelph at 12 km/h =

[tex]\frac{24}{12}=2[/tex] hours

Time taken by Julian for return trip at 8 km/h = [tex]\frac{24}{8}=3[/tex] hours

As given, the total distance is 24 + 24 = 48 km.

And the total time is 2 + 3 = 5 hrs.

Hence, the average speed for the entire trip is = [tex]\frac{48}{5}= 9.6[/tex]

The answer is 9.6 km/hour.

9282 divided by 433 with a remainder is equal to 21.

Given data:

To divide 9282 divided by 433, we can use variables to represent the numbers and perform the division algebraically.

Let's denote 9282 as a dividend (D) and 433as divisor (d).

D = 9282

d = 433

We need to find the quotient (Q) when D is divided by d.

Q = D / d

Substituting the given values:

Q = 9282 / 433

To simplify the division, we can multiply both the numerator and denominator by a suitable power of 10 to eliminate the decimal point. In this case, multiplying by 10 will suffice:

Q = (9282 * 10) / (433* 10)

Q = 9282 / 433

Now, we can perform the division:

Q = 9282 / 17

So, Q = 21

The quotient is the final answer, and the remainder is 0. Therefore, 9282 divided by 433 with a remainder is equal to 21.

Answer: [tex]421.56+20g+\frac{k}{4}[/tex]

Step-by-step explanation:

You have the following information given in the problem above:

- She had $421.56 in her checking account.

- She she deposited g $20 bills  (which you can rewrite: [tex]20g[/tex]) and k quarters (which you can rewrite as folllowing:[tex]\frac{k}{4}[/tex]).

Therefore, the amount of money in her account after the deposit is the sum of the amoun she had in her account plus the amoun of money she deposited.

Then, you can write the following expression:

[tex]421.56+20g+\frac{k}{4}[/tex]

Answer:

421.56 + 20g + 1/4 k

Step-by-step explanation:

Joby had $421.56, and she deposited g $20 bills, and k quarter:

We don´t know how many $20 bills she deposited but we know it is expressed by the letter g, so she deposited $20g, and we add to that how many quarters of a dollar she added, in this case, we know that she deposited k quarters or 1/4 k dollars.

To write an expression to know the amount of money she has after the deposit we have to add:

What she had before the deposit = $421.56

The Dollars in $20 bills, we know it is = 20g

The number of dollars in a quarter of a dollar = 1/4 k

So we write:

421.56 + 20g + 1/4k

An equation in standard form for a hyperbola with center (0, 0), vertex (0, 17), and focus (0, 19) is;  y²/172 – x²/(6√2)² = 1

We are given that the hyperbola has;

Center (0, 0), Vertex (0, 17) and Focus (0, 19)

The general form of equation of the given hyperbola has a form of;

y²/a²  - x²/b² = 1

Where;

±a is the y- coordinates of the vertices of the parabola (or y-intercepts).

b determines the asymptotes of the hyperbola in the equation y = ± (a/b)x.

From the vertex coordinates of (0.17), we have that; a = ± 17.

From the focus coordinates (0, 19), the y-coordinate of it is; c = 19 .

b can be found from Pythagorean theorem;

c² = a² + b²

Thus;

192 = 172 + b²

b² = 192 – 172

b² = 361 – 289

b = √72 = 6√2

The equation of the hyperbola is;

y²/172 – x²/(6√2)² = 1

#SPJ2

The equation in standard form for a hyperbola with the given center, vertex, and focus is y² / 289 - x² / a² = 1.

The equation of a hyperbola in standard form is given by:

(x - h)² / a² - (y - k)² / b² = 1 or

(y - k)² / b² - (x - h)² / a² = 1

Given that the center is (0,0) and the vertex is (0,17), we can see that the hyperbola is vertically oriented. Therefore, we can use the form (y - k)² / b² - x² / a² = 1.

Since the center is (0,0), the value of (h, k) is (0,0).

The distance between the center and the vertex is 17 units, which corresponds to the value of b.

The distance between the center and the focus is 19 units, which corresponds to the value of c.

Substituting these values into the equation gives: (y - 0)² / 17² - x² / a² = 1

The equation in standard form for the hyperbola is therefore y² / 289 - x² / a² = 1

C. 80

EXPLANATION

The longer diagonal is serving as the hypotenuse of the right triangles.

Let the longer side of the kite be x cm.

Then, from the Pythagoras Theorem, the sum of the length of the squares of the two shorter legs equals the square of the hypotenuse.

This means that,

[tex] {x}^{2} + {60}^{2} = {100}^{2} [/tex]

[tex] {x}^{2} + 3600 = 10000[/tex]

[tex] {x}^{2} = 10000 - 3600[/tex]

[tex] {x}^{2} = 6400[/tex]

[tex]x = \sqrt{6400} [/tex]

Step-by-step explanation:

The area of a parallelogram is A = b*h. Substitute b = 8 and h= 6 to find the area.

A = 8*6 = 48

The area of a triangle is A = 1/2 b*h. Substitute h = 6 and b = 16 since the triangle has a length of 8 as well as the whole parallelogram.

A = 1/2 *16*6 = 48

Together the areas equal 48 + 48 = 96

Answer:

TT→T

Step-by-step explanation:

If p is false, then ~p is true.

If q is false, then ~q is true.

Now note that

In your case, both~p and ~q are true, then ~p→~q is true too (or TT→T)

The truth value of the conditional statement ∼p → ∼q is true when both p and q are false, as the conditional is false only when the antecedent is true and the consequent is false.

The question is asking us to evaluate the truth value of the conditional statement ∼p → ∼q when both p and q are false. According to the rules of propositional logic, the implication (→) is false only when the antecedent is true and the consequent is false. Here, since p and q are both false, the antecedent (∼p) is true and the consequent (∼q) is also true. Therefore, the conditional statement is true. This reflects the concept that a conditional statement is always true if either the antecedent is false or the consequent is true, hence in our case the truth value of ∼p → ∼q is true.

[tex]\large\boxed{(x-5)^2+(y-3)^2=5^2\to(x-5)^2+(y-3)^2=25}[/tex]

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have the end points of a diameter (8, 6) and (2, 0). The midpoint of a diameter is a center of a circle. Half of a length of diameter is a length of a radius.

The formula of a midpoint of a segment:

[tex]\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)[/tex]

Substitute:

[tex]x=\dfrac{8+2}{2}=\dfrac{10}{2}=5\\\\y=\dfrac{6+0}{2}=\dfrac{6}{2}=3[/tex]

The center of a circle is (5, 3).

The formula of a length of a segment:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute:

[tex]d=\sqrt{(2-8)^2+(0-6)^2}=\sqrt{(-8)^2-(-6)^2}=\sqrt{64+36}=\sqrt{100}=10[/tex]

The length of a diameter is 10 units. The length of a radius r = 10 : 2 = 5 units.

Finally we have the equation of a circle:

[tex](x-5)^2+(y-3)^2=5^2[/tex]

Bella used 2/9 of a paper pack, which amounts to 72 pieces of paper. To find out how many pieces of paper were in the pack to begin with, we need to calculate the total amount of paper in the pack.

Let's set up a proportion where the total number of sheets is x. Since 2/9 of the total is 72, we can write the equation as follows:

So, the paper pack originally contained 324 pieces of paper.
