Which statement correctly describes the solution to this scenario?

Answer:

[tex]\frac{5}{2\sqrt{6} }[/tex]

Step-by-step explanation:

Since Θ is in fourth quadrant then cosΘ > 0, as is secΘ

Given

sinΘ = - [tex]\frac{1}{5}[/tex], then

cosΘ = [tex]\sqrt{1-(-1/5)^2}[/tex]

         = [tex]\sqrt{1-\frac{1}{25} }[/tex] = [tex]\sqrt{\frac{24}{25} }[/tex] = [tex]\frac{2\sqrt{6} }{5}[/tex]

Hence

secΘ = [tex]\frac{1}{\frac{2\sqrt{6} }{5} }[/tex] = [tex]\frac{5}{2\sqrt{6} }[/tex]

Answer:

[tex]\sec(\theta)=\frac{5\sqrt{6}}{12}[/tex]

The answer is the last one.

Step-by-step explanation:

If we are in quadrant 4, then x (cosine) is positive and y (sine) is negative.

Since cosine is positive, secant is positive because secant is the reciprocal of cosine.

So we already know the answer is not the 1st one or the 3rd one.

I'm going to use a Pythagorean Identity to find cosine value of theta.

[tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex]

Enter in -1/5 for [tex]\sin(\theta)[/tex]:

[tex]\cos^2(\theta)+(\frac{-1}{5})^2=1[/tex]

Simplify a bit:

[tex]\cos^2(\theta)+\frac{1}{25}=1[/tex]

Subtract 1/25 on both sides:

[tex]\cos^2(\theta)=1-\frac{1}{25}[/tex]

Write 1 as 25/25 so you have a common denominator on the right hand side:

[tex]\cos^2(\theta)=\frac{25}{25}-\frac{1}{25}[/tex]

[tex]\cos^2(\theta)=\frac{24}{25}[/tex]

Take the square root of both sides:

[tex]\cos(\theta)=\pm \sqrt{\frac{24}{25}}[/tex]

[tex]\cos(\theta)=\pm \frac{\sqrt{24}}{\sqrt{25}}[/tex]

I will worry about simplifying the square root part when finding secant.

We said that cosine was positive because we were in the fourth quadrant.

[tex]\cos(\theta)=\frac{\sqrt{24}}{\sqrt{25}}[/tex]

Now recall that cosine and secant are reciprocals of each other:

[tex]\sec(\theta)=\frac{\sqrt{25}}{\sqrt{24}}[/tex]

Let's simplify the square part not.

Usually people hate the square root on both and also if you look at your choices none of the choice have square root on bottom.

So we are going to multiply top and bottom by [tex]\sqrt{24}[/tex]. I'm going to also write 5 instead of [tex]\sqrt{25}[/tex].

[tex]\sec(\theta)=\frac{5}{\sqrt{24}} \cdot \frac{\sqrt{24}}{\sqrt{24}}[/tex]

[tex]\sec(\theta)=\frac{5\sqrt{24}}{24}[/tex]

Now let's simplify the square root of 24.

We know 24 is not a perfect square, but 24 does contain a factor that is a perfect square. That factor is 4.

[tex]\sec(\theta)=\frac{5\sqrt{4}\sqrt{6}}{24}[/tex].

[tex]\sec(\theta)=\frac{5(2)\sqrt{6}}{24}[/tex]

[tex]\sec(\theta)=\frac{10\sqrt{6}}{24}[/tex]

Now both 10 and 24 share a common factor of 2 so let's divide top and bottom by 2:

[tex]\sec(\theta)=\frac{5\sqrt{6}}{12}[/tex]

The answer is the last one.

First we can rewrite the equation to,

[tex]x^2+2x-3=0[/tex]

Which factors to,

[tex](x+3)(x-1)=0[/tex]

And this leads towards two solutions,

[tex]x_1\Longleftrightarrow x+3=0\Longrightarrow x_1=-3[/tex]

and,

[tex]x_2\Longleftrightarrow x-1=0\Longrightarrow x_2=1[/tex]

The answer is A.

Hope this helps.

Answer:

c

Step-by-step explanation:

Given

x² + 2x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 3 + 1

(x + 1)² = 4 ( take the square root of both sides )

x + 1 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 1 from both sides )

x = - 1 ± 2, hence

x = - 1 - 2 = - 3 and x = - 1 + 2 = 1

Answer:

29/12 > x

Step-by-step explanation:

–3(x + 2) > 4x + 5(x – 7)

Distribute

-3x -6 > 4x +5x-35

Combine like terms

-3x-6 > 9x -35

Add 3x to each side

-3x+3x-6 > 9x+3x -35

-6 > 12x-35

Add 35 to each side

-6+35 > 12x -35+35

29 > 12x

Divide each side by 12

29/12 > 12x/12

29/12 > x

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.

I believe the answer would be 12.4 the first choice.

Answer:

=12.4 units

Step-by-step explanation:

We can use the Pythagoras theorem to find the lengths of EF, FG, and HE

(GF)²=(ΔX)²+(Δy)²

(GF)²=(2--1)²+(4-3)²

=3²+1²

=10

GF=√10=3.16 units

(EF)²=(Δx)²+(Δy)²

=(2--1)²+(6-4)²

=3²+2²

=9+4

=13

EF=√13=3.61 units

(HE)²=(Δx)²+(Δy)²

=(-1--3)²+(6-3)²

=2²+3²

=4+9

=13

HE=√13=3.61 units

GH=(-1--3)=2 units

Perimeter =GF+EF+EH+HG

=3.16+3.61+3.61+2

=12.38 units

=12.4 units to 1 decimal place.

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.

As per the concept of arithmetic sequence, there are 259 multiples of three between 10 and 787

To solve this problem, we need to find the first and last multiples of three within the given range and then count how many integers are there in between

Step 1: Find the first multiple of three greater than or equal to 10.

The first multiple of three greater than or equal to 10 is 12.

Step 2: Find the last multiple of three that is less than or equal to 787.

The largest multiple of three less than or equal to 787 can be calculated as follows:

Divide 787 by 3:

787 ÷ 3 ≈ 262.33

The largest multiple of three less than or equal to 787 is:

262 × 3 = 786

Step 3: Count the multiples of three within the range.

Now that we have found the first and last multiples of three within the range, we need to count the number of multiples of three between them, including the endpoints.

The multiples of three between 12 and 786 are:

12, 15, 18, ..., 783, 786.

Step 4: Calculate the total count of multiples.

To calculate the total count, we can use the formula for finding the number of terms in an arithmetic sequence:

Number of terms = (last term - first term) / common difference + 1.

In this case, the first term is 12, the last term is 786, and the common difference (the difference between consecutive terms) is 3.

Number of terms = (786 - 12) / 3 + 1

Number of terms = 774 / 3 + 1

Number of terms = 258 + 1

Number of terms = 259.

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.

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]

The area of the circle is found using the formula Area = PI x r^2

The area of a triangle is found using the formula Area = 1/2 x base x height.

Using the given dimensions:

Area of the circle = 3.14 x 3.8^2 = 45.3416 square units.

The area of the triangle is 1/2 x 5 x 10 = 25 square units.

To find the area of the unshaded part, subtract the area of the shaded triangle from the circle:

Area = 45.3416 - 25 = 20.3416

Round to two decimal places = 20.34

The answer is D. 20.34

D. 20.34

In this case, we must calculate first the Areas of the Triangle ([tex]A_{t}[/tex]), in square units, and the Circle ([tex]A_{c}[/tex]), in square units, later we subtract the Area of the former from the Area of the latter to determine the Area of unshaded region ([tex]A_{u}[/tex]), in square units. The Area formulas for each figure are, respectively:

Triangle

[tex]A_{t} = \frac{1}{2}\cdot b\cdot h[/tex] (1)

Circle

[tex]A_{c} = \pi\cdot r^{2}[/tex] (2)

Unshaded Area

[tex]A_{u} = A_{c} - A_{t}[/tex] (3)

Where:

[tex]h[/tex] - Height of the triangle.

[tex]b[/tex] - Base of the triangle.

[tex]r[/tex] - Radius of the circle.

If we know that [tex]h = 10[/tex], [tex]b = 5[/tex] and [tex]r = 3.8[/tex], then the area of the unshaded region is:

[tex]A_{t} = \frac{1}{2}\cdot (5)\cdot (10)[/tex]

[tex]A_{t} = 25[/tex]

[tex]A_{c} = \pi\cdot 3.8^{2}[/tex]

[tex]A_{c} \approx 45.365[/tex]

[tex]A_{u} = 45.365-25[/tex]

[tex]A_{u} = 20.365[/tex]

The correct answer is D.

We need to figure out what we can multiply to 7 to get -14.

Hopefully it is the same number or this isn't a dilation.

So to get from pre-image to image you need to multiply by -2 because -11*-2=22 and 7*-2=-14.

The scale factor is -2.

The required scale factor is -2

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

The c is always the y-intercept. In this case, you can see that it's 7. The graph clearly shows 7 as it's y-intercept as well, so that matches well.

Sadly, I do not know how to compare the 8x into this situation without a calculator, but that information should be quite enough to see how that function is in that graph.

Answer:

situation 1 : flat rate of 50....1.50 per movie.....after 1 month her bill is 66.25

66.25 = 1.50x + 50

situation 2 : flat rate of 60....1.25 for every movie...

y = 1.25x + 60

both situations have a flat rate fee plus a charge for every movie. In situation 1, u can solve for x (the number of movies rented) because u know how much she was charged. However, in situation 2, without more information, u cannot solve this equation...what u would need to solve it would either be the number of movies rented or the total bill showing what she was charged. So basically, in situation 1, u are given more information then in situation 2.....enough information to be able to solve for the variable x...whereas, in situation 2, u are not given enough info to solve for a variable and get a numerical answer

BRAINLIEST PLEASE!!!!!

Answer: Situation 1 involves one independent variable that stands for the number of movies Melinda rented. Situation 1 gives a total for the monthly bill, but situation 2 does not give a total for the monthly bill. Because situation 2 leaves the total value out, it needs an additional variable. Therefore, situation 2 involves two variables—the number of movies Kimberly rented (the independent variable) and the monthly cable bill (the dependent variable). In this situation, we can’t solve for one variable without knowing the other.
