Answer:(number)=-5

Step-by-step explanation:

You can use simple logic in order to solve this equation.

An equation that has infinitely many solutions will have the same exact numbers on both sides

Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true

The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

Step-by-step explanation:

there are 5 data points

3*40 =120

5*52.5 = 262.5

8*65 =520

3*77.5=232.5

11*90=990

total frequency = 3+5+8+3+11 =30

total sum = 2125

Step-by-step explanation:

The exact value of sec(30°) is 2√3 / 3.

We have,

To find the exact value of sec(30°), use the trigonometric identity:

sec(θ) = 1 / cos(θ)

Now,

cos(30°) = √3 / 2

Now, substitute this value into the formula for sec(θ):

sec(30°) = 1 / cos(30°) = 1 / (√3 / 2)

sec(30°) = 2 / √3

To rationalize the denominator, multiply the numerator and denominator by √3:

sec(30°) = 2 / √3 * √3 / √3

= 2√3 / 3

Therefore,

The exact value of sec(30°) is 2√3 / 3.

The vertices of the image triangle after the glide reflection are D'(1, 7), E'(7, 5), F'(2, 1) and both the triangles are not congruent

Graph of triangle DEF with vertices D(1,-1), E(7,-3), F(2,-7):

To graph the triangle, plot the given coordinates on a coordinate plane and connect the points to form a triangle.

D(1,-1), E(7,-3), F(2,-7)

Graph of triangle DEF under a glide reflection where the translation is (x,y) —> (x, y+8):

To perform the glide reflection, we first apply the translation by adding 8 to the y-coordinate of each vertex, and then we reflect the resulting triangle across a line parallel to the direction of the translation.

Translation: (x,y) —> (x, y+8)

Applying the translation to the original triangle DEF:

D(1, -1+8) = D(1, 7)

E(7, -3+8) = E(7, 5)

F(2, -7+8) = F(2, 1)

Now we have the new vertices for the translated triangle:

D(1, 7), E(7, 5), F(2, 1)

Next, we reflect this translated triangle across a line parallel to the direction of the translation. Since the direction of the translation is vertical, the reflection line will also be vertical.

The resulting image triangle after the glide reflection will have the same vertices as the translated triangle, but mirrored vertically.

The vertices of the image triangle after the glide reflection are:

D'(1, 7)

E'(7, 5)

F'(2, 1)

The original triangle DEF and the image triangle after the glide reflection are not congruent.

Answer:

46 cm

Step-by-step explanation:

I learned this formula in math last year

The cost that will maximize the demand, considering the quadratic function, is given as follows:

$3.

The quadratic function representing the demand is given as follows:

y = -10x² + 60x + 180.

The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:

x = -b / (2a)

The coefficients of the quadratic function in this problem are given as follows:

a = -10, b = 60.

The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:

x = -60/(2 x (-20))

x = 3.

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

Step-by-step explanation:

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
