I'm not sure understanding this at ALLLLL

The answers are:

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. Each plater drinks approximately 24 ounces of sports drink at practice.

E. For each additional player that takes a drink, there will be approximately  24 fewer ounces of sporks drink remaining after the practice.

We are given the equation:

[tex]y=f(x)=648-24x[/tex]

Let's discard each of the given options in order to find the three correct options.

A. The cooler is meant to be used only by 24 players: False.

If we want to calculate how many players can use the cooler, we need to isolate "x" (rate of change) from the given equation, so, isolating we have:

[tex]f(x)=648-24x[/tex]

[tex]0=648-24x[/tex]

[tex]648=24x\\\\24x=648\\\\x=\frac{648}{24}=27[/tex]

We have that the cooler can be used by 27 players, so, the first option that states that "The cooler is meant to be used only by 24 players" is false.

B. Before practice, there are 648 ounces of sports drink in the cooler: True.

We have that before the practice when the cooler is not being used by any player (or there is no any player) has 648 ounces (full), we can calculate it making the variable "x" equal to 0, so, calculating we have:

[tex]f(x)=648-24x[/tex]

[tex]f(0)=648-24*(0)=648[/tex]

Therefore, we have that the statement "Before practice, there are 648 ounces of sports drink in the cooler." is true.

C. Each plater drinks approximately 24 ounces of sports drink at practice: True.

From the statement, we know that the rate of change is equal to (-24), and it's equal to the number of ounces that each player drinks.

Hence, we have that the statement  "Each plater drinks approximately 24 ounces of sports drink at practice." is true.

D. If  24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink: False.

If we want to calculate the number of ounces that 24 players will drink, we need to use the slope value. If we know that each player drinks 24 ounces, so, to calculate how many ounces of sports drink will 24 players drink, we need to use the following equation:

[tex]DrankOunces=24oz*Players\\\\DrankOunces=24oz*24=576oz[/tex]

We have that 24 players will drink a total of 576 ounces, so, the statement "If  24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink." is false.

E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice: True.

From the statement and the equation, we know that the slope (rate of change) is negative, meaning that for each player (x) it will be 24 fewer ounces of sports drink after practice, for example, calculating for 1 and 2 players, we have:

[tex]f(1)=648-24*1=624[/tex]

[tex]f(x)=648-24*2=600[/tex]

We can see that for each player, it will be 24 fewer ounces of sports drink after practice.

Hence, we have that the statement "For each additional player that takes a drink, there will be approximately  24 fewer ounces of sporks drink remaining after the practice." is true.

Therefore, the correct options are:

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. Each plater drinks approximately 24 ounces of sports drink at practice.

E. For each additional player that takes a drink, there will be approximately  24 fewer ounces of sporks drink remaining after the practice.

[tex]x+2[/tex] is a factor of [tex]x^5+32[/tex] because (by the remainder theorem) the remainder upon dividing [tex]x^5+32[/tex] by [tex]x+2[/tex] is [tex](-2)^5+32=0[/tex].

There's also the sum of fifth powers formula,

[tex]a^5+b^5=(a+b)(a^4-a^3b+a^2b^2-ab^3+b^4)[/tex]

ANSWER

The correct answer is A

EXPLANATION

The given polynomial is

[tex]p(x) = {x}^{5} + 32[/tex]

According to the remainder theorem, if p(x) is divided by x+2 the remainder is p(-2).

If the remainder is zero then x+2 is a factor of f(x).

We plug in x=-2 into the function to obtain;

[tex]p( - 2) = { (- 2)}^{5} + 32[/tex]

[tex]p( - 2) = - 32 + 32[/tex]

[tex]p( - 2) = 0[/tex]

Since the remainder is zero, x+2 is a factor.

Answer:

[tex]\log_{13}(169)=2[/tex]

Step-by-step explanation:

The given exponential form is:

[tex]169=13^2[/tex]

The base of the given expression on the right is 13 and the exponent is 2.

The number is 169.

In terms of logarithms, the base still remains the base and the exponent becomes the result of the logarithm of the number 169 to the given base 13.

[tex]\log_{13}(169)=2[/tex]

Answer:

Jenny's Stats

t = m - 2

d = 60 miles

r = r1 + 10

Maureen's stats

d = 50 miles

t = m

r = r1

=======

60 = (r1 + 10) * (m - 2)

50 = r1 * m

m = 50/r1

60 = (r1 + 10)* (50/r1 - 2)  

60 = 50 + 500/r1 - 2r1 - 20

60 = 30 + 500/r1 - 2r1

60r1 = 30r1 + 500 - 2*r1^2

30r1 = 500 - 2r1^2

2r1^2 + 30r1 - 500

This quadratic factors into

2 (r1 - 10)(r1 + 25)

r1 = 10 mph             The 25 has no meaning.

m = 50/r1

m = 50/10

m = 5 hours

m - 2 = 3 hours.

Answer:

[tex]a_n=3(3)^{n-1}[/tex]

Step-by-step explanation:

We have the following sequence

3,9,27,81,243

Note that if you divide each term of the sequence between the previous term you get:

[tex]\frac{9}{3} = 3\\\\\frac{27}{9} = 3\\\\\frac{81}{27} = 3[/tex]

then the radius of convergence of the series is r.

therefore this is a geometrical series.

The formula to find the general term [tex]a_n[/tex] of the geometric sequence is:

[tex]a_n=a_1(r)^{n-1}[/tex]

Where

[tex]a_1[/tex] is the first term of the sequence

Then the general term for this sequence is:

[tex]a_n=3(3)^{n-1}[/tex]

The answers are:

Second step:

First box, 4

Second box,

The width is:

[tex]x+4[/tex]

Fourth step:

Box, 16

The length cant be -16in,  the length is 12in, and the width is 16in.

To solve the problem, we are using the formula to calculate the area of a rectangle, however, since the dimensions of the rectangle are not constant numbers, we will work with the variable "x", also, we know that the area of the cookie sheet is equal to 192 square inches.

So, solving we have:

First step:

We have the expression:

[tex]x^{2} +x[/tex]

Which is equal to: [tex]192in^{2}[/tex]

So,

[tex]x^{2} +4x=492[/tex]

Second step:

We have that the common factor of the left side of the equation is "x", so, we can simplify the expression in the following way:

[tex]x(x+4)=492[/tex]

Now, using the formula to calculate the area of a rectangle, we have:

[tex]length*width=Area\\\\length*width=92in^{2}\\\\x(x+4)=192in^{2}[/tex]

Where,

The length of the rectangle is "x"

The width of the rectangle is "x+4"

Third step:

Rewriting the expression, we have:

[tex]x^{2} +4x-192=0[/tex]

We need to find the roots (zeroes) of the quadratic function, in order to find the width of the rectangle without using the variable "x".

So, finding the values of "x" (roots or zeroes of the expression), we have:

[tex]x^{2} +4x-192=0[/tex]

Fourth step:

We need to find two numbers which it product gives as result the number -192 (including its sign) and their algebraic sum gives as result "4", those numbers are, -12 and 16,

[tex]-12*(16)=-192\\-12+16=4[/tex]

Then, rewriting the equation, we have:

[tex](x+16)(x-12)=0[/tex]

So, we that the expression is equal to 0 for two values of "x", these values are:

[tex]x_1=-16\\x_2=12[/tex]

Now, since the length can't be -16in, its equal to 12in.

[tex]length=x=12in[/tex]

[tex]length=12[/tex]

Then, from the second equation, we have that:

[tex]width=x+4[/tex]

Substituting "x" we can find the value of the width, so:

[tex]width=x+4=\\\\width=12+4=16in[/tex]

Hence, we have:

[tex]length=12in\\width=16in[/tex]

Answer:

Step-by-step explanation:

Given a polynomial with zeros x = a, x = b, x = c

Then the factors are (x - a), (x - b) and (x - c)

and the polynomial is the product of the factors

f(x) = k(x - a)(x - b)(x - c) ← k is a multiplier

here the zeros are x = - 3, x = 0, x = 4, thus the factors are

(x - (- 3)), (x - 0) and (x - 4), that is

(x + 3), x and (x - 4)

let k = 1, then

f(x) = x(x + 3)(x - 4) → 3

Answer:

F(x) = x(x + 3)(x – 4)

Step-by-step explanation:

The polynomial function has zeros at -3, 0, and 4  is F(x) = x(x + 3)(x – 4)

x(x + 3)(x – 4), set each part = 0 to find the solutions

x(x + 3)(x – 4) = 0

x = 0

x + 3 = 0; x = -3

x - 4 = 0; x = 4

a) The graph of the function is illustrated below.

b) The rocket's maximum height is 64 feet, it takes 2 seconds to reach this height.

c) The total time it was in the air is 4 seconds.

(A) Quadratic Function: To model the height of the rocket as it moves upward, we use a quadratic function in the form h(t) = at² + bt + c, where h(t) represents the height of the rocket at time t seconds. Since the rocket is moving vertically, we consider the acceleration due to gravity, which is -32 feet per second squared. The initial velocity of the rocket is 64 feet per second, so the coefficient of the linear term, b, is 64.

The equation for the height of the rocket is: h(t) = -16t² + 64t

(B) Graphing on the Coordinate Plane: To graph the quadratic function, we plot points on a coordinate plane. The vertex of the parabola represents the maximum height of the rocket, and the t-intercepts correspond to the times when the rocket hits the ground. The vertex of a quadratic function in the form h(t) = at² + bt + c is given by the coordinates (t_v, h(t_v)), where

t_v = -b / 2a.

In this case,

t_v = -64 / 2(-16) = 2 seconds.

(C) Finding Rocket's Maximum Height and Time in the Air: The vertex point we found earlier is (2, 64). This means that the rocket reaches its maximum height of 64 feet after 2 seconds of flight. To find the maximum height, we plug the value of t_v back into the equation:

h(t_v) = -16(2)² + 64(2) = -16(4) + 128 = 64 feet.

The rocket's maximum height is 64 feet, and it takes 2 seconds to reach this height. To find the total time the rocket is in the air, we look at the t-intercepts on the graph, which correspond to the times when the rocket hits the ground. From the equation h(t) = -16t² + 64t, we set h(t) to 0 and solve for t:

0 = -16t² + 64t t(0) = 0 (corresponding to the initial time of launch) t(4) = 4 seconds.

The rocket is in the air for 4 seconds.

Answer:

 The measure of G = 9.2°

Step-by-step explanation:

From the figure we can write,

The measure of <G is half the  the measure of arc AD

To find the value of x

We have  AD = (6x - 80)° and 2G = (x + 2)°

6x - 80 = (x + 2)

6x - 80 = x + 2

6x - x = 82

5x = 82

x = 82/5 = 16.4

To find the measure of <gG

m<G = (x + 2 )/2

 = (16.4 + 2)/2 = 18.4 = 9.2

Therefore the measure of <G =  9.2°

That is very true.

In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa. The inverse of multiplication is division and vice versa.

Addition and subtraction are indeed inverse operations. They are algebraic operations that do the opposite of one another and can thus 'undo' each other's effects.

The statement that Addition and subtraction are inverse operations is indeed true. In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. In the case of addition and subtraction, they do exactly that. For instance, if you were to add 3 and 4 to get 7, you can undo this operation by subtracting 3 or 4 from 7 which will give back the other original number. Hence, addition and subtraction are deemed as inverse operations.

Step-by-step explanation:

The surface  area of right cone is calculated by the following formula

[tex]A = \pi r *\sqrt{r^2 +h^2}+\pi r^2[/tex]

Where r is the radius of the cone and h is the height

In this case we know that the diameter d of the base is:

[tex]d=2r[/tex]

So the radius is:

[tex]r=\frac{d}{2}\\\\r=\frac{6}{2}\\\\r=3\ units[/tex]

and

[tex]h=8\ units[/tex]
