Answer:

$1200.00

Step-by-step explanation:

Let x = the discounted priced

x + .13x = 7684  Combine like terms.

1.13x = 7684  Divide both sides by 1.13

[tex]\frac{1.13x}{1.13}[/tex] = [tex]\frac{7684}{1.13}[/tex]

x = 6800

$6800 is the cost of the discounted article before tax.

8000 - 6800 = 1200

1. The offer price of the 800 shares of a mutual fund with a NAV of $14.10 that Bill Roundy bought is $11,280.

2. For this investment, Bill paid $11,618.40, including the load charge of 3%.

A load charge is a sales commission that investors pay when they buy (front-end load) or redeem (back-end load) shares in a mutual fund.

NAV means net asset value.

NAV refers to the difference between the investee company's total assets and its total liabilities.

The total number of mutual fund shares bought by Bill = 800

The net asset value of the shares = $14.10

Load charge = 3%

Offer price = $11,280 (800 x $14.10)

Amount Bill paid for the investment = $11,618.40 ($11,280 x 1.03)

Thus, with an offer price of $11,280 for the mutual fund, Bill Roundy paid a total of $11,618.40, including the load charge.

The other two angle measures of triangle XYZ are 35° and 75°.

We are given that the triangles PQR and XYZ are similar.

Also, ∠ZXY = 70°  and ∠PRQ = 35°.

Now, we know that when two triangles are similar, then the corresponding angles are same.

Therefore, ∠XZY = ∠PRQ = 35°

Now, in triangle XYZ, we have ∠XZY = 35° and ∠ZXY = 70°.

Since, we know that the sum of the angles of a triangle is 180°.

So, ∠XZY + ∠ZXY + ∠ZYX = 180°

i.e. 35° + 70° + ∠ZYX = 180°

i.e. ∠ZYX = 180° - ( 35° + 70° )

i.e. ∠ZYX = 180° - 105°

i.e. ∠ZYX = 75°

Hence, the other two angle measures of triangle XYZ are 35° and 75°.

The dimensions of the rectangle of maximum area are the length of 12√3 units and width of 4 units

Given that the ellipse has the equation: x²/144 + y²/16 = 1

Make x the subject:

x²/144 + y²/16 = 1

(x²+9y²)/144 = 1

x² + 9y² =144

x² = 144-9y²

x = √(144-9y²)

The  rectangle vertices is at (x,y), (-x,y), (x,-y), (-x,-y). Thus, the rectangle has a length and width of 2x and 2y respectively

The area of a rectangle inscribed inside an ellipse is given by:

Area (A) = 4xy

A = 4(√(144-9y²))y

A = 4y√(144-9y²)

A = 4√(144y²-9y⁴)

The maximum area of the rectangle is at dA/dy = 0  

dA/dy = 4[144-18³y/ (√(144y²-9y⁴))]

4[144-18y³/ (√(144y²-9y⁴))] = 0

144-18y³= 0

18y³ = 144

y³ = 144/18

y³ = 8

y = ∛8

y = 2

x = √(144-9y²)

x = √(144 - 9(2)²)

x = √108

x = 6√3

Thus, the dimensions are the length = 2x = 2×(6√3) = 12√3 units, the width = 2y = 2×2 = 4 units

Answer:

Step-by-step explanation:

You want the graphed figure dilated by different scale factors around different center points.

To find the image of a dilated point, figure how far it is from the center of dilation, then multiply that distance by the scale factor. Plot the image point at that distance from the center of dilation in the same direction as the original point.

Dilation by a factor of 1/2 cuts all the distances in half. 2 grid squares become 1; 4 grid squares become 2.

Dilation by a factor of 2 multiplies all the distances by 2. 2 grid squares become 4; 4 grid squares become 8.

In the attached graph, the points are labeled with subscripts a, b, c according to the dilation they correspond to. Note that the center of dilation doesn't move, so Q and Q_a are the same point, and S and S_c are the same point.

Solving the equation x^2 + (y- 5)^2 = 30 for isolating x^2 is x^2 = - y^2 + 10y + 5. (Option D)

Equation is a mathematical statement that expresses values of two mathematical expressions as equal and is indicated by the sign =.

In order to isolate x^2 in the equation x^2 + (y- 5)^2 = 30, the remaining terms must be solved and simplified and collected on the other side.

Given equation is:

x^2 + (y- 5)^2 = 30

Expanding the (y- 5)^2 using formula for square of the difference between the two terms.

In general form: (a – b)^2 = a^2 – 2ab + b^2

Hence,

(y- 5)^2 = y^2 – 2(y)(5) + 5^2 = y^2 – 10y + 25

The original equation becomes,

x^2 + y^2 – 10y + 25 = 30

Subtract y^2 – 10y + 25 from both sides and simplifying:

x^2 + y^2 – 10y + 25 – (y^2 – 10y + 25) = 30 – (y^2 – 10y + 25)

x^2 = 30 – y^2 + 10y - 25

x^2 = - y^2 + 10y + 5

Note: The question is incomplete as it is missing options which are A. x^2 = y^2 + 10y+5 B. x^2 =-y^2 + 10y+25 C. x^2 = 30 - y^2 D. x^2 = - y^2 + 10y+5

This z-score tells you x = 34 is 2.75 standard deviations to the right of mean. And the mean is 23.

What is standard deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

Given:

Annie averages 23 points per basketball game with a standard deviation of 4 points.

Suppose Annie's points per basketball game are normally distributed.

Let X = the number of points per basketball game.

X ~ N(23,4) means E(X) = 23, SD(X) = 4

Mean = 23 , Standard deviation = 4

So,

A vertical shift is a movement up or down the y-axis, and it's represented by a change in the value of the y-intercept. A horizontal shift is a movement left or right along the x-axis, and in the equation of a function it's a change in the value of x before it's multiplied by the slope.

Vertical Shifts

One simple kind of transformation involves shifting the entire graph of a function up, down, right, or left. The simplest shift is a vertical shift, moving the graph up or down, because this transformation involves adding a positive or negative constant to the function. In other words, we add the same constant to the output value of the function regardless of the input. For a function  

g(x) =f(x)+k,  the function  f(x)  is shifted vertically  k  units.

Horizontal Shifts

We just saw that the vertical shift is a change to the output, or outside, of the function. We will now look at how changes to input, on the inside of the function, change its graph and meaning. A shift to the input results in a movement of the graph of the function left or right in what is known as a horizontal shift,

Given a function  f, a new function  g(x)=f(x−h) , where  h  is a constant, is a horizontal shift of the function  f . If  h is positive, the graph will shift right. If  h is negative, the graph will shift left.
