Answer:

{0}

Step-by-step explanation:

14 + 8m = 14 - 3m - 5m

Combine like terms

14 + 8m = 14 - 8m

Add 8m to each side

14 +8m +8m = 14 -8m +8m

14 +16m = 14

Subtract 14 from each side

14-14 +16m = 14-14

16m = 0

Divide by 16

16m/16 = 0/16

m = 0

Answer:

{0}

Step-by-step explanation:

The given equation is

[tex]14+8m=14-3m-5m[/tex]

We need to find the solution set of given equation.

Combine like terms on the right side of the given equation.

[tex]14+8m=14+(-3m-5m)[/tex]

[tex]14+8m=14+(-8m)[/tex]

[tex]14+8m=14-8m[/tex]

Add 8m on both sides.

[tex]14+8m+8m=14-8m+8m[/tex]

[tex]14+16m=14[/tex]

Subtract 14 from both sides.

[tex]14+16m-14=14-14[/tex]

[tex]16m=0[/tex]

Divide both sides by 16.

[tex]m=\frac{0}{16}[/tex]

[tex]m=0[/tex]

Therefore, the solution set is {0}.

Answer:

Options b and D

Step-by-step explanation:

It's a question of Boolean's algebra

We will find the truth values of each statement p, q, r, and s first.

p : An isosceles triangle has two congruent sides.

Means truth value is True

q ; A right angle measures 90°

Truth value of this statement will be True

r : Four Points are always coplanar.

Truth value of this statement will be False.

s : A decagon has 12 sides

Truth value of the statement will be False.

Now we come to the options.

a. Four points are always coplanar and a right angle measures 90°.

Here "and" means conjunction and truth value of conjuncion of two statements will be true if only both the statements are true.

r        q         r ∧ q

T        T            T

But the truth value is given as false so not the correct option.

b. Four points are always coplanar and a right angle measures 90°.

As we have discussed in option a. truth value of the conjunction is True so this option will be the correct option.

c. Four points are always coplanar or a right angle measures 90°

OR means it's a disjunction and truth value of disjunction is false only when both the statements are False.

r         q        r ∨ q

T        T           T

But the truth value is given as False, so this option is not correct.

d. Four points are always coplanar or a right angle measure 90°

As discussed in option c. Truth value will be True. so this option will be the correct option.

Options b and d are the correct options.  

Answer:

It's an acute angled triangle.

Step-by-step explanation:

15^2 = 225

12^2 = 144

10^2 = 100

Adding:

10^2 + 12^2 = 244.

So as 15^2 <  12^2 + 10^2 this is an acute angled triangle.

The triangle with given sides of 10 inch , 12 inch and 15 inch is an acute angled triangle.

The length of three sides of a triangle are given

Length of first  side = 10 inch

Length of second side = 12 inch

Length of third side = 15 inch

here we can observe that the third side is the longest side for the given triangle

Let us check whether the given triangle satisfies the Pythagorean theorem

For a right angled Pythagorean theorem is given by equation (1)

[tex]\rm H^2 = P^2 + B^2 .........(1)\\where \\H = Hypotenuse\\P = Perpendicular\\B = Base\\[/tex]

From the given data we can conclude that

[tex]\rm 15 ^2 = 225 \\10^2 = 100\\12^2 = 144 \\15^2 \neq 10^2 +12^2 \\\\Since\; 225\neq 244[/tex]

The given triangle does not satisfies the Pythagorean theorem and hence it is not a right angled triangle

also [tex]225< 244[/tex]

So we can conclude that it is an acute angled triangle.

Answer:

The volume of this pyramid is 16 cm³.

Step-by-step explanation:

The volume [tex]V[/tex] of a solid pyramid can be given as:

[tex]\displaystyle V = \frac{1}{3} \cdot b \cdot h[/tex],

where

Here's how to solve this problem with calculus without using the previous formula.

Imaging cutting the square-base pyramid in half, horizontally. Each horizontal cross-section will be a square. The lengths of these squares' sides range from 0 cm to 3 cm. This length will be also be proportional to the vertical distance from the vertice of the pyramid.

Refer to the sketch attached. Let the vertical distance from the vertice be [tex]x[/tex] cm.

As a result, the length of a side of the square will be

[tex]\displaystyle \frac{x}{3}\times 4 = \frac{4}{3}x[/tex].

The area of the square will be

[tex]\displaystyle \left(\frac{4}{3}x\right)^{2} = \frac{16}{9}x^{2}[/tex].

Integrate the area of the horizontal cross-section with respect to [tex]x[/tex]

[tex]\displaystyle \begin{aligned}\int_{0}^{3}{\frac{16}{9}x^{2}\cdot dx} &= \frac{16}{9}\int_{0}^{3}{x^{2}\cdot dx}\\ &= \frac{16}{9}\cdot \left(\frac{1}{3}\int_{0}^{3}{3x^{2}\cdot dx}\right) & \text{Set up the integrand for power rule}\\ &= \left.\frac{16}{9}\times \frac{1}{3}\cdot x^{3}\right|^{3}_{0}\\ &= \frac{16}{27}\times 3^{3} \\ &= 16\end{aligned}[/tex].

Step-by-step explanation:

Answer:

The function f(x) intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.

Step-by-step explanation:

In this question you first form the table for values of x with corresponding values of f(x) that you will use to graph the function f(x)=x².Then do the same for the function g(x)=x²+2.Take a point from the parent function f(x) and compare it with its image in the function g(x) to identify the transformation that occurred.Graph the two equations to visually see the x-intercepts in both equations.

In the parent function f(x)=x² form a table as shown below;

x                      f(x)=x²          coordinate to plot

-3                     -3²=9                (-3,9)

-2                      -2²=4                (-2,4)

-1                        -1²=1                 (-1,1)

0                         0²=0               (0,0)

1                           1²=1                 (1,1)

2                          2²=4               (2,4)

3                           3²=9               (3,9)

Use the coordinates to plot the graph of f(x)=x² on a graph tool and see the number of x-intercept values

In the function g(x)=x²+2 also form your table for values of g(x) with corresponding values of x

x                              g(x)=x²+2                                          coordinate to plot

-3                          -3²+2=9+2=11                                          (-3,11)

-2                          -2²+2=4+2=6                                          (-2,6)

-1                           -1²+2=1+2=3                                             (-1,3)

0                            0²+2=2                                                    (0,2)

1                             1²+2=1+2=3                                              (1,3)

2                            2²+2=4+2=6                                             (2,6)

3                            3²+2=9+2=11                                             (3,11)

Use the coordinates to plot the graph of g(x)=x²+2  on a graph tool to determine the number of x intercept values

You can determine the transformation that occurred too, how?

Take a point on the parent function f(x) and compare it with its image in the function g(x)

Let take point (-3,9) and compare it to (-3,11).You notice x coordinate did not change but the y coordinate shifted 2 units upwards along the y-axis.To determine this dilation you subtract the coordinates of object point from that of image point.

[tex]=(\frac{0-0}{11-9}) =(\frac{0}{2} )=(0,2)[/tex]

The dilation was (0,2)

Solution

From the graphs, the function f(x), intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.

(4x³ + 3x² - 6x) - ( 10x³ + 3x²)

To find the simplified form

(4x³ + 3x² - 6x) - ( 10x³ + 3x²) = 4x³ + 3x² - 6x - 10x³ - 3x²

 = 4x³ - 10x³ + 3x² - 3x² - 6x

Acute

Step-by-step explanation:

Note the definitions:

Obtuse: At least one of the angles are greater than 90°

Equilateral: All angles are congruent & equal to 60°

Acute: All angles are less than 90°

Right: At least one angle is equal to 90°

In this case, the triangle is a D) acute, for it fits the requirement for being an acute... all angles are less than 90°.

~

Hello There!

The triangle shown in the image would be an acute triangle

An acute triangle is a triangle where all three sides are less than 90°

In the image, none of the angles shown are greater than 90° so this

is an example of an acute triangle

For this case we have to:

Let[tex]u = x + 1[/tex]

So:

[tex]u ^ 2-4u + 2 = 0[/tex]

We have the solution will be given by:

[tex]u = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]

Where:

[tex]a = 1\\b = -4\\c = 2[/tex]

Substituting:

[tex]u = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (1) (2)}} {2 (1)}\\u = \frac {4 \pm \sqrt {16-8}} {2}\\u = \frac {4 \pm \sqrt {8}} {2}\\u = \frac {4 \pm \sqrt {2 ^ 2 * 2}} {2}\\u = \frac {4 \pm2 \sqrt {2}} {2}[/tex]

The solutions are:

[tex]u_ {1} = \frac {4 + 2 \sqrt {2}} {2} = 2 + \sqrt {2}\\u_ {2} = \frac {4-2 \sqrt {2}} {2} = 2- \sqrt {2}[/tex]

Returning the change:

[tex]2+ \sqrt {2} = x_ {1} +1\\x_ {1} = 1 + \sqrt {2}\\2- \sqrt {2} = x_ {2} +1\\x_ {2} = 1- \sqrt {2}[/tex]

Answer:

[tex]x_ {1} = 1 + \sqrt {2}\\x_ {2} = 1- \sqrt {2}[/tex]

Answer: 1st - x = 1 + √2 & 4th- x= 1 - √2

Step-by-step explanation:

bearing in mind that the rate of change will just be the slope or namely the derivative of the expression.

[tex]\bf f(x)=3+e^x(x-5)^3\implies \cfrac{df}{dx}=0+\stackrel{\textit{product rule}}{e^x(x-5)^3+\stackrel{\textit{chain rule}}{e^x\cdot 3(x-5)^2\cdot 1}} \\\\\\ \cfrac{df}{dx}=e^x(x-5)^3+3e^x(x-5)^2\implies \cfrac{df}{dx}=\stackrel{\textit{common factor}}{e^x(x-5)^2[(x-5)+3]} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \cfrac{df}{dx}=e^x(x-5)^2(x-2)~\hfill[/tex]

a) The possibility space is completed with the potential outcomes of spinning both spinner A and spinner B.

b) The probability of getting a negative score is 2/9.

c) The probability of scoring more than 3 is also 2/9.

a) **Possibility Space:**

```

                            Spinner A

                             2         4         6

Spinner B    3       1          -1        -3

                       6       4          0         -2

                       9       7          3          1

```

In the possibility space, each cell represents the outcome of spinning both spinner A and spinner B. The score is obtained by subtracting the number on spinner A from the number on spinner B.

b) **Probability of Getting a Negative Score:**

To calculate the probability of getting a negative score, count the number of occurrences where the result is negative and divide it by the total number of possible outcomes. In this case, there are two instances (-1 and -2) where the score is negative. The total number of outcomes is 9.

Probability of negative score = Number of negative outcomes / Total number of outcomes

Probability of negative score = 2 / 9

c) **Probability of Scoring More Than 3:**

To find the probability of scoring more than 3, count the number of occurrences where the result is greater than 3 and divide it by the total number of possible outcomes. In this case, there are two instances (4 and 7) where the score is more than 3.

Probability of scoring more than 3 = Number of outcomes > 3 / Total number of outcomes

Probability of scoring more than 3 = 2 / 9

Answer: D is correct dotted and shaded below

Step-by-step explanation:

It’s a dotted line because the symbol is < or >

Everything below the line will be shaded because it’s y<, if it were y> then everything would be shaded above

Answer:

A shaded region below a dashed boundary line

Step-by-step explanation:

Conveniently it has been established, that in inequalities graph dashed lines indicate that all the points ∈ line expressed by y< -1/2x+5 part of the inequality are not included. So we represent by shaded regions below dashed lines.

If this inequality was then expressed by y<= -1/2x +5 then a solid line would then represent.

Answer:

D.

Increase by more than 0.25 dollars.

Step-by-step explanation:

What is the gross margin %?

Margin % = (2.50/1.00) * 100 = 250%

If the cost goes up 0.25 what will the  selling price have to do to maintain a markup of 250%?

250% =(x/1.25) * 100%

Divide by 100%

250 / 100 = x / 1.25

2.5 = x / 1.25  

Multiply both sides by 1.25

2.5 * 1.25 = x

3.125 = x

But that is really not the question. The question is, how much higher is that now than it used to be?

3.125 - 2.50 = 0.625 cents.

So you would have to increase the selling price by more than 0.25

At=4.5+3+3+4.5+10+2.5=27.5 units²

Answer:

Option D.

Step-by-step explanation:

As we know area of a triangle = [tex]\frac{1}{2}\times Base\times Height[/tex]

1. Area of ΔJKL = [tex]\frac{1}{2}\times(\text{Distance of L from base JK})\times (JK)[/tex]

= [tex]\frac{1}{2}\times (3)\times (5)[/tex]

=7.5 square units

2. Area of ΔIJL = [tex]\frac{1}{2}\times(\text{Distance of J from base IL})\times (IL)[/tex]

=  [tex]\frac{1}{2}\times (3)\times (5)[/tex]

= 7.5 square units

3. Area of triangle IKL = [tex]\frac{1}{2}\times(\text{Distance of H from base IL})\times (IL)[/tex]

= [tex]\frac{1}{2}\times (5)\times (5)[/tex]

= [tex]\frac{25}{2}=12.5[/tex] square units

A = -120

AX = -240

X = 2

Step-by-step explanation:

∵ x + 4y - z = -14

∵ 5x + 6y + 3z = 4

∵ -2x + 7y + 2z = -17

\left[\begin{array}{ccc}1&4&-1\\5&6&3\\-2&7&2\end{array}\right]=\left[\begin{array}{ccc}-14\\4\\-17\end{array}\right]

∴ A = 1(6×2 - 3×7) + (-4)(2×5 - 3×-2) + (-1)(5×7 - 6×-2)

∴ A = 1(12 - 21) + (-4)(10 - -6) + (-1)(35 - -12)

∴ A = -9 + (-4)(16) + (-1)(47) = -9 - 64 - 47 = -120

To find X replace the column of X by the column of the answer

\left[\begin{array}{ccc}-14&4&-1\\4&6&3\\-17&7&2\end{array}\right]

∴ AX = -14(6×2 - 3×7) + (-4)(4×2 - 3×-17) + (-1)(4×7 - 6×-17)

∴ AX = -14(12 - 21) + (-4)(8 - -51) + (-1)(28 - -102)

∴ AX = 126 + (-4)(59) + (-1)(130) = 126 - 236 - 130 = -240

∴ X = AX/A = -240/-120 = 2

the equation of the trend line is y = -7x + 4.

To find the equation of the trend line using two points, we need to determine the slope (m) and the y-intercept (b) of the line. The slope is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the given points.

For the points (-4, 32) and (7, -45), the slope would be:

m = (-45 - 32) / (7 - (-4))

m = (-77) / (11)

m = -7

Now, we use the slope and one point to find the y-intercept using the point-slope form of the equation of a line, y - y1 = m(x - x1), and then we convert it to the slope-intercept form, y = mx + b.

Using point (-4, 32), the equation becomes:

32 = -7(-4) + b

32 = 28 + b

b = 32 - 28

b = 4

So, the equation of the trend line is y = -7x + 4.
