Answer:

$ 7360.00

Step-by-step explanation:

100 shares   *   $ 73/share   + $60  = $ 7360

Based on the calculation below,  the total purchase price for this transaction is $7,360.

The total purchase price for this transaction can be calculated using the following formula:

Total purchase price = (Price per share * Units of shares purchased) + Commission ...................................... (1)

Substituting all the values into equation (1), we have:

Total purchase price = ($73 * 100) + $60 = $7,360

Answer:

x=79/5 or 15.8

Step-by-step explanation:

....................

Answer:

[tex]\frac{79}{5}[/tex]

Step-by-step explanation:

Combine [tex]\frac{1}{3}[/tex] and x.

[tex]\frac{x}{3} +\frac{11}{15}=6[/tex]

Move all terms not containing x to the right side of the equation.

[tex]\frac{x}{3}=\frac{79}{15}[/tex]

Multiply both sides of the equation by 3.

3[tex]\frac{x}{3}[/tex]=3([tex]\frac{79}{15}[/tex])

Then 3 cancels out on the left side so all is left is 3.

On the right side, you need to multiply.

3 times 79 is 237.

Now simplify and you get:

79/5

An inequality that can be used to describe the possible values of x is; C. 0 < x < 14

From the given image, let us first use sine rule to find the angles in the triangle with sides 12, 6 and 7 and angle 120°. Thus;

7/sin α = 12/sin 102

sin α = (7/12) * sin 102

sin α = 0.570586

α = sin⁻¹0.570586

α = 34.8°

We know that sum of angles in a triangle is 180°. Thus;

34.8° + 90° + (7x + 4) = 180°

124.8 + 7x + 4 = 180

7x = 180 - 128.4

x = 51.6/7

x = 7.37

Looking at the given options, x cannot be negative and that rules out the first option. x is greater than 8/7 and that rules out the second option but x is greater than 0 and less than 14 and so option C is correct.

A function assigns the values. The value of (gof)(3) is -576.

A function assigns the value of each element of one set to the other specific element of another set.

(gof)(x) = g(f(x))

           = -(x+21)²

The value of (gof)(3) will be,

The expected length of the arc containing the point (1,0) is; π

First of all, it is pertinent to note that the lengths of the four arcs in which the circle is divided by the three points and (1, 0) have identical distributions.

The problem is same as dividing a circle of length 2π at four points chosen at random, and labelling one of them (1, 0). Now, let us make L₁, L₂, L₃, L₄ to be the lengths of the four arcs determined by those four points.

Thus, we have;

L₁ + L₂ + L₃ + L₄ = 2π

Whereas, the expected value of several random variables is additive as;

E[ L₁ + L₂ + L₃ + L₄] =  [EL₁] + [EL₂] + [EL₃] + [EL₄]

By symmetry the lengths have the same probability distribution and as such; [EL₁] = [EL₂] = [EL₃] = [EL₄] and the sum must be 2π. Thus, we can say that each expected value is 2π/4 = π/4.

Finally, the expected value of the arc containing the point (1, 0) is the sum of the expected values of the two arcs that are adjacent to (1, 0), i.e.,

π/2 + π/2 = π

Answer:

Step-by-step explanation:

The product of the slopes of two perpendicular lines is -1.

If the slopes of the diagonals are 1 and -1, then their product is -1, and they are perpendicular.

Answer: D

A sentence that describes what Talia should do to show that the diagonals of the square are perpendicular is: D. show that the slope of SQ is 1 and the slope of PR is -1.

In order for a quadrilateral to be a square, the two (2) pairs of its sides must be equal (congruent) and perpendicular to each other.

Therefore, we would have to calculate the slope of each side by using this mathematical equation:

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m₁) of SQ = (a - 0)/(a - 0)

Slope (m₁) of SQ = a/a = 1.

Slope (m₂) of PR = (a - 0)/(0 - a)

Slope (m₂) of PR = -a/a = -1.

Based on the condition for two (2) perpendicular lines, we have:

m₁ × m₂ = -1

1 × -1 = -1

-1 = -1

Answer:

6.6 cm and 14.6 cm

Step-by-step explanation:

(a)

the length of arc AB is calculated as

AB = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{95}{360}[/tex]

     = 2π × 4 × [tex]\frac{95}{360}[/tex]

     = 8π × [tex]\frac{95}{360}[/tex]

     = [tex]\frac{8\pi (95)}{360}[/tex]

     ≈ 6.6 cm ( to the nearest tenth )

(b)

the perimeter (P) of sector AOB is

P = r + r + AB = 4 + 4 + 6.6 = 14.6 cm

Step-by-step explanation:

3.

the circumference of a circle is

2×pi×r

r = 4 cm

so, we know, the full circle circumference is

2×pi×4 = 8×pi = 25.13274123... cm

a.

the arc length of AB is the part of the whole circumference that corresponds to 95° out of the full 360° of a whole circle.

arc AB = 8×pi × 95/360 = pi × 95/45 = pi × 19/9 =

= 6.632251158... cm

b.

the perimeter of OAB (the "pie slice") is then the arc AB plus 2 radius lengths (from the end points on the arc to the center of the circle) :

pi × 19/9 + 2×4 = pi×19/9 + 8 = 14.632251158... cm
