Final answer:

The two-digit number in question is 96, as it has one digit as 9 and is divisible by 6.

Explanation:

The student is asking to find a two-digit number where one of the digits is 9, and the number is divisible by 6 without any remainder. To solve this, we need to remember that for a number to be divisible by 6, it must be divisible by both 2 and 3. A two-digit number is divisible by 2 if its last digit is even.

Since one of the digits is 9 (an odd number), the other digit must be even, so our options for the two-digit numbers with a 9 are 90, 92, 94, 96, and 98. To be divisible by 3, the sum of the digits must be divisible by 3. Out of our options, only 96 has a sum of digits (9 + 6) that is divisible by 3. Therefore, the number we are looking for is 96.

Step-by-step explanation:

First you have 8 movies to watch.

A day passes you have 7 left, then another day passes you have 6 left...

You do this until you have 1 movie left because by then you'd have watched 7 movies in 7 days of a week.

Take the product: 8 * 7 * 6 * 5...*2*1 = 8! = 40,320

Answer: C. 40,320

Step-by-step explanation:

Given : The total number of movies = 8

Also, in one week if you watch one movie a day , then the number of possible movies you can watch in next week must be 7.

Now, the number of ways to watch 8 movies taking 7 movies from is given by permutations :-

[tex]^8P_7=\dfrac{8!}{(8-7)!}\\\\=\dfrac{8!}{1!}=8\times7\times6\times5\times4\times3\times2\times1\\\\=40,320[/tex]

If parabolas open down, then their vertices are at a maximum point, whereas if parabolas open up, their vertices are at a minimum point.

I hope this was the answer you were looking for, and as always, I am joyous to assist anyone at any time.

To find the max/min of a function, find where the function's first derivative is zero. Check those points with the second derivative: a positive value indicates a minimum and a negative value indicates a maximum.

To find the maximum or minimum of a function, you should first understand that these points occur where the derivative of the function is zero, which corresponds to the points with a flat tangent line (no slope). To derive this, differentiate the function and mark all the points where the derivative equals zero. These are potential maximum or minimum points, also known as extrema.

However, it's also important to note that a zero derivative does not always mean a maximum or minimum is present. To confirm this, you need to perform the second-derivative test. If after differentiating the first derivative you get a positive value, the original function has a minimum at that point. If it's negative, the function has a maximum.

For example, let's take the function f(x) = x². The derivative f'(x) = 2x, and setting this to zero gives us x = 0 as the only point whose derivative equals zero. Further, the second derivative, f''(x), equals 2, which is positive, indicating a minimum occurs at x = 0.

Answer:

The function is odd because it is symmetric about the origin.

Step-by-step explanation:

we know that

A function f(x) is even when

f(x)=f(-x) ----> the function is symmetry about the y-axis

A function is odd when

-f(x)=f(-x) ---> the function is symmetry about the origin

In this problem we have

f(x)=-5x

Verify if the function is even

For x=1 ----> f(1)=-5(1)=-5

For x=-1 ---> f(-1)=-5(-1)=5

so

f(x) is not equal to f(-x)

therefore The function is not even

Verify if the function is odd

we have

f(1)=-5

f(-1)=5

so

-f(1) is equal to f(-1)

-f(x)=f(-x)

therefore

The function is odd because it is symmetric about the origin.

Look at the picture.

Read the coordinates of the intersection of the line (solution).

Answer:

(-4,8)

Step-by-step explanation:

Given system of equations,

[tex]y=-\frac{3}{2}x+2-----(1)[/tex]

[tex]y=5x+28------(2)[/tex]

In equation (1), If x = 0, y = 2,

If y = 0,

[tex]-\frac{3}{2}x+2=0\implies -\frac{3}{2}x=-2\implies -3x=-4\implies x=\frac{4}{3}[/tex]

Join the points (0,2) and (4/3,0) in the graph we get the line (1),

In equation (2), if x = 0, y = 28,

If y = 0,

[tex]5x+28=0\implies 5x=-28\implies x=-5.6[/tex]

Join the points (0, 28) and (-5.6,0) in the graph we get the line (2),

Hence, by graph,

The intersection point of line (1) and (2) is (-4,8)

Which is the required solution.

Answer:

1 is not a function

2 is a function because you can write it (AS) f(x)=1/(2x).

Step-by-step explanation:

1) x^2+y^2=9 is a circle with center (0,0) and radius 3.

To get this all I did was compare to (x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.

A circle is not a function.

You can solve solve for and see that you will get two values for y which is no go for a function.

Let's do that:

[tex]x^2+y^2=9[/tex]

Subtract x^2 on both sides:

[tex]y^2=9-x^2[/tex]

Square root both sides:

[tex]y=\pm \sqrt{9-x^2}[/tex].

2) 2xy=1

Divide both sides by 2x:

y=1/(2x).

This is a function only one y there.

Answer:

Option 2 is correct

[tex]g(x) = (\frac{1}{2})5^{(x+3)}+2[/tex]

Step-by-step explanation:

We can se ethat the given function is an exponential function.

The function is:

5^x

In order to compress the function the original function is multiplied a constant.

As the function is compressed by a factor of 1/2

The function will become:

g(x) = 1/2 * 5^x

Now the function is shifted to left which is a horizontal shift. For horizontal shift of n units, n is added to the power so the function will become:

[tex]g(x) = \frac{1}{2}5^{x+3}[/tex]

Then the function is shifted upwards two units, the vertical shhift is added to the whole function so the function will become:

[tex]g(x) = (\frac{1}{2})5^{(x+3)}+2[/tex]

Hence, Option 2 is correct ..

Given information: BCDE is a rectangular casing, DE = 3 cm and BE = 3 cm.

We need to find the smallest diameter of pipe that will fit the fiber optic line. It means we have to find the measure of DB.

The measure of all interior angles of a rectangle or square is 90°.

[tex]\angle DEB=90^{\circ}[/tex]

It means the DEB is right angled triangle.

According to the Pythagoras theorem:

[tex]hypotenuse^2=leg_1^2+leg_2^2[/tex]

In triangle DEB,

[tex](DB)^2=(DE)^2+(BE)^2[/tex]

[tex](DB)^2=(3)^2+(3)^2[/tex]

[tex](DB)^2=9+9[/tex]

[tex](DB)^2=18[/tex]

Taking square root both sides.

[tex]DB=\sqrt{18}[/tex]

[tex]DB=4.24264068712[/tex]

[tex]DB\approx 4.24[/tex]

Therefore the correct option is C.

Based on the information given, the smallest diameter will be C. 4.24 cm.

DB² = 3² + 3²

DB² = 9 + 9

DB² = 18

DB = ✓18

DB = 4.24

Step-by-step explanation:

I think that thing inside the box says 4x-5.

The numbers we are putting in are 2,7, and 11.

So when we put 2 in we get 4(2)-5 which is 8-5=3.

When we put 7 in we get 4(7)-5 which is 28-5=23.

When we put 11 in we get 4(11)-5 which is 44-5=39

Answer:

[tex]p=4[/tex]

[tex]x=\frac{-1}{2} \pm \frac{\sqrt{3}}{2}i[/tex]

Step-by-step explanation:

We are given (x+3) is a factor of [tex]x^3+4x^2+px+3[/tex], which means if were to plug in -3, the result is 0.

Let's write that down:

[tex](-3)^3+4(-3)^2+p(-3)+3=0[/tex]

[tex]-27+36-3p+3=0[/tex]

[tex]9-3p+3=0[/tex]

[tex]9+3-3p=0[/tex]

[tex]12-3p=0[/tex]

[tex]12=3p[/tex]

[tex]p=4[/tex]

So the cubic equation is actually [tex]x^3+4x^2+4x+3=0[/tex] that they wish we solve for [tex]x[/tex].

To find another factor of the given cubic expression on the left, I'm going to use synthetic division with that polynomial and (x+3) where (x+3) is divisor.  Since (x+3) is the divisor, -3 will be on the outside like so:

-3 |  1    4    4     3

   |       -3   -3    -3

     ---------------------

      1      1     1      0

So the other factor of [tex]x^3+4x^2+4x+3[/tex] is [tex](x^2+x+1)[/tex].

We must solve [tex]x^2+x+1=0[/tex].

Compare this to [tex]ax^2+bx+c=0[/tex].

We have [tex]a=1,b=1, \text{ and } c=1[/tex].

The quadratic formula is

[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex].

Plug in the numbers we have for [tex]a,b, \text{ and } c[/tex].

[tex]x=\frac{-1 \pm \sqrt{1^2-4(1)(1)}}{2(1)}[/tex].

Simplify inside the square root while also performing the one operation on bottom:

[tex]x=\frac{-1 \pm \sqrt{1-4}}{2}[/tex]

[tex]x=\frac{-1 \pm \sqrt{-3}}{2}[/tex]

Now our answer will include an imaginary part because of that sqrt(negative number).

The imaginary unit is [tex]i=\sqrt{-1}[/tex].

So our final answer is:

[tex]x=\frac{-1}{2} \pm \frac{\sqrt{3}}{2}i[/tex]

Final answer:

To find the value of p, substitute -3 into the polynomial since (X+3) is a factor, thus yielding p=3. With p known, the polynomial becomes [tex]x^3 + 4x^2 + 3x + 3[/tex] = 0, and can now be solved for x.

Explanation:

Finding the Value of p

Given the polynomial [tex]x^3 + 4x^2 + px + 3[/tex] and the fact that (X+3) is a factor, we can use polynomial division or synthetic division to find the value of p. Since (X+3) is a factor, when we substitute -3 for x in the polynomial, the result should be zero.

Substituting -3 into the polynomial yields:
[tex](-3)^3 + 4(-3)^2 + p(-3) + 3[/tex] = 0
-27 + 36 - 3p + 3 = 0
9 - 3p = 0.

Solving for p gives us:
3p = 9
p = 3.

Solving the Equation

Now that we know p, we rewrite the polynomial as [tex]x^3 + 4x^2 + 3x + 3 = 0[/tex] and use the fact that (X+3) is a factor to perform the division. The remainder of the division gives us a quadratic polynomial which we can solve using the quadratic formula or factoring.

The entire region that belongs to your graph is greater than drawn line.

Draw another graph using the same easy coordinates.

[tex]y=2x-1[/tex]

First point is (0.5,0) and the other (0,-1)

The entire region that belongs to your graph is lesser than the drawn line.

Answer:

Graph A.

Step-by-step explanation:

The given inequalities are

[tex]y>-2x+2[/tex]

[tex]y<2x-1[/tex]

The related equation of given inequalities are

[tex]y=-2x+2[/tex]

[tex]y=2x-1[/tex]

The slope of line (1) is -2 and the y-intercept is 2.

The slope of line (2) is 2 and the y-intercept is -1.

Both related lines are dotted line because the points on the line are not included n the solution set.

Check each inequality by (0,0).

[tex]0>-2(0)+2\Rightarrow 0>2[/tex] False statement

[tex]0<2(0)-1\Rightarrow 0<-1[/tex] False statement

So, (0,0) is not included in the shaded area of any of these two inequities.

Therefore, graph A shows the solution to the system of linear inequalities.

Answer:

For every real number x, C expresses the solution to the inequality

Final answer:

To find the solution to the inequality x + 3 < 1, subtract 3 from both sides to get x < -2. The number line would have an open circle at -2 and be shaded to the left, indicating all numbers less than -2.

Explanation:

To solve the inequality x + 3 < 1, we need to find the value of x that makes the inequality true. We start by subtracting 3 from both sides of the inequality:

The number line for this inequality would have an open circle at -2 (since -2 is not included in the solution) and shade to the left of -2 to show that all numbers less than -2 are included. The reason we shade to the left is because those are the numbers that are less than -2, thus satisfying the inequality.

Step-by-step explanation:

Let x in be the base side length and y in be the height of the box. Since the base is a square, we have

[tex]S=x^2\Rightarrow x=\sqrt{S}[/tex]

The volume of the box is

[tex]V=S\cdot y\\ \\36=Sy\Rightarrow y=\dfrac{36}{S}[/tex]

The surface area of the box is

[tex]SA=2x^2+4xy\\ \\SA(S)=2S+4\cdot \sqrt{S}\cdot \dfrac{36}{S}=2S+\dfrac{144}{\sqrt{S}}[/tex]

The graph of the function SA(S) is shown in attached diagram.

Find the derivative of this function:

[tex]SA'(S)=(2S+144S^{-\frac{1}{2}})'=2-\dfrac{1}{2}\cdot 144\cdot S^{-\frac{1}{2}-1}=2-\dfrac{72}{S\sqrt{S}}[/tex]

Equate this derivative to 0:

[tex]2-\dfrac{72}{S\sqrt{S}}=0\\ \\2S\sqrt{S}=72\\ \\S\sqrt{S}=36\\ \\S^{\frac{3}{2}}=6^2\\ \\S=6^{\frac{4}{3}}[/tex]

So, the dimensions that produce a minimum surface area for this aluminum box are:

[tex]x=\sqrt{6^{\frac{4}{3}}}=6^{\frac{2}{3}} \ in\\ \\y=\dfrac{6^2}{6^{\frac{4}{3}}}=6^{\frac{2}{3}}\ in.[/tex]

Answer:

0.1469

Step-by-step explanation:

Given from the question;

Mean=8.4 hrs=μ

Standard deviation=1.8 hrs=δ

Sample size, n=40

Let  x=8.7

z=(x-μ)÷(δ÷√n)  

Find z(8.7)

z=(8.7-8.4)÷(1.8÷√40)

z={0.3×√40}÷1.8=1.05409

z=1.0541

Read from the  standard normal probabilities table

P(z>1.0541)

=0.1459

Final answer:

Using the Central Limit Theorem and standard error calculation, the probability that the mean rebuild time by 40 mechanics exceeds 8.7 hours is found to be approximately 0.1469.

Explanation:

To find the probability that the mean rebuild time for a 2005 Chevrolet Cavalier transmission by 40 mechanics exceeds 8.7 hours, given that the mean is 8.4 hours and the standard deviation is 1.8 hours, we will use the concept of the sampling distribution of the sample mean. Since the standard deviation of the population is known, we apply the Central Limit Theorem, which states that the distribution of the sample means will be approximately normal if the sample size is large enough (n>30 in this case).

First, calculate the standard error of the mean (SEM) using the formula: SEM = σ/√n, where σ is the standard deviation of the population and n is the sample size. Therefore, SEM = 1.8/√40 = 0.285.

Next, find the z-score that corresponds to a mean rebuild time of 8.7 hours using the formula: z = (X - μ)/SEM, where X is the value of interest (8.7 hours), and μ is the population mean (8.4 hours). Thus, z = (8.7 - 8.4)/0.285 = 1.05.

Finally, look up the z-score in a z-table or use a statistical calculator to find the probability that Z is greater than 1.05, which is approximately 0.1469.

Therefore, the probability that their mean rebuild time exceeds 8.7 hours is 0.1469.
