Answer:

reads 64 pages in one hour

Step-by-step explanation:

For simplicities' sake, we'll convert 1/4 of an hour into 15 minutes (60 minutes x 1/4 = 15 mins)

Since we have a ratio, of 16 pages to 15 mins, we can create the ratio by making a fraction of 16/15. Since we want to get to 1 hour, to find how many pages she read in an hour, we can multiply the top and bottom (to equalize) by 4 (because 4 x 15 = 60).

16•4/15•4

64/60

Because of this, we can see that the ratio is now 64 pages to 60 mins or one hour. Therefore, she reads 64 pages in one hour.

Answer:

64

Step-by-step explanation:

To do this problem you have to figure out Michelle's hourly rate for reading pages. We are given that she will read 16 pages in 1/4 of an hour. This means that in 15 minutes (60 minutes in an hour / 4 for the 1/4 an hour) she will read 16 pages. We only have 15 minutes though and need 60 minutes so 60/15 gives us 4. This means that we will need 4, 15 minute periods to get to a hour. So 4*15minutes = 60 minutes or one hour and 16pages*4 = 64 pages. So in one hour she will read 64 pages.

A faster way to do this is to just multiply both sides by the recripical.

16 pages = 1/4 hour

*4/1              *4/1

64 pages = 4/4 hour

64 pages = 1 hour

The standard form for the circle x² - 10x + y² + 14y - 7 = 0 is (x - 5)² + (y + 7)² = 81. The correct answer is D.

To find the standard form of the given circle, we must complete the square by rearranging the equation and adding constants to both sides of the equation to create perfect squares. Here are the steps:

1. Rearrange the equation so that the x and y terms are together:
x² - 10x + y² + 14y = 7

2. Complete the square for the x terms by adding (10/2)² = 25 to both sides of the equation:
x² - 10x + 25 + y² + 14y = 7 + 25

3. Complete the square for the y terms by adding (14/2)² = 49 to both sides of the equation:
x² - 10x + 25 + y² + 14y + 49 = 7 + 25 + 49

4. Simplify the equation by factoring the perfect squares:
(x² - 10x + 25) + (y² + 14y + 49) = 7 + 25 + 49

(x - 5)² + (y + 7)² = 81

So, the standard form for this circle is (x - 5)² + (y + 7)² = 81, which is option D.

Step-by-step explanation:

Since tangent is negative and is equal to the ratio of opposite over adjacent, we can assume that the angle theta lies in either the third or the fourth quadrant, where the x and y coordinates have opposite signs.

In the third quadrant, sine is positive and cosine is negative. Therefore, we have:

tangent theta = opposite/adjacent = -1

sine theta = opposite/hypotenuse > 0

cosine theta = adjacent/hypotenuse < 0

Using the Pythagorean identity, we have:

sin² theta + cos² theta = 1

=> opposite²/hypotenuse² + adjacent²/hypotenuse² = 1

=> opposite² + adjacent² = hypotenuse²

Since we are given that 3π/2 < theta < 2π, we can place the triangle in the third quadrant with a reference angle of π/2. This means that the opposite side is equal to the absolute value of the adjacent side. Let's assume that the hypotenuse is equal to 1, then we have:

opposite/adjacent = -1

=> opposite = -adjacent

opposite² + adjacent² = hypotenuse²

=> adjacent² + (-adjacent)² = 1

=> 2adjacent² = 1

=> adjacent = ±1/√2

Since cosine is negative in the third quadrant, we have:

cosine theta = adjacent/hypotenuse = -1/√2

Finally, we can use the reciprocal identity to find secant:

secant theta = 1/cosine theta = -√2

Therefore, the answer is A. Negative StartRoot 2 EndRoot.

The value of tangent theta is equal to the negative 1. At this value the value of secant theta is [tex]\sqrt{2}[/tex].

The equation y^(2)-x+10=0 has no symmetry.

Symmetry is when one part of an equation is the mirror image of another part. In this case, there is no symmetry because the equation cannot be mirrored on any axis.

To check for symmetry with respect to the y-axis, we can replace x with -x and see if the equation is still true. In this case, y^(2)-(-x)+10=0 is not the same as the original equation, so there is no symmetry with respect to the y-axis.

Similarly, to check for symmetry with respect to the x-axis, we can replace y with -y and see if the equation is still true. In this case, (-y)^(2)-x+10=0 is not the same as the original equation, so there is no symmetry with respect to the x-axis.

Finally, to check for symmetry with respect to the origin, we can replace x with -x and y with -y and see if the equation is still true. In this case, (-y)^(2)-(-x)+10=0 is not the same as the original equation, so there is no symmetry with respect to the origin.

a.  The total number of possible outcomes is 16 x 96 = 1,536.

b. She should expect to see a difference of 1 approximately 12/16 x 96 = 72 times.

c. She should expect to see a difference of 0 approximately 8/16 x 96 = 48 times.

a) There are a total of 16 possible pairs of numbers that can be rolled on the two pyramids:

(1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (2,4), (3,1), (3,2), (3,3), (3,4), (4,1), (4,2), (4,3), and (4,4).

We can use a probability distribution to calculate the probability of each pair of numbers being rolled. Since each pyramid has four sides, there are 4 x 4 = 16 possible outcomes when both pyramids are rolled. Therefore, the probability of each outcome is 1/16.

Since Natalie is going to toss each pair of pyramids 96 times, the total number of possible outcomes is 16 x 96 = 1,536.

To calculate the difference between each pair of numbers, we can simply subtract the smaller number from the larger number.

Here is a table that shows the probability of each difference:

Difference                  Possible Pairs                           Probability

0                               (1,1), (2,2), (3,3), (4,4)                            4/16 = 1/4

1                               (1,2), (1,3), (1,4), (2,3), (2,4), (3,4),          12/16 = 3/4

                                     (2,1), (3,1), (4,1), (3,2), (4,2), (4,3)  

2                                None                                             0

3                                None                                             0

Therefore, the probability of the difference being 0 is 1/4, the probability of the difference being 1 is 3/4, and the probability of the difference being 2 or 3 is 0.

Since Natalie is going to conduct the experiment a total of 96 times, we can use these probabilities to calculate the expected number of times each difference will occur:

Difference             Probability          Expected Number of Occurrences

0                                1/4                     96 x 1/4 = 24

1                                 3/4                     96 x 3/4 = 72

2                                      0                     96 x 0 = 0

3                                 0                     96 x 0 = 0

b) we can expect the difference between each pair of numbers to be 0 about 24 times and

We would need to know the percentage of discount offered during the sale to determine the sale price of the polo shirt. Here's an example calculation for a 25% discount:

If the discount offered is 25%, Bert will only need to pay 75% of the original price. We can calculate this as:

Sale price = (100% - 25%) x $20

Sale price = 75% x $20

Sale price = 0.75 x $20

Sale price = $15

Therefore, if the discount offered during the sale is 25%, Bert will pay $15 for the polo shirt. However, if the discount is different, the sale price will be different.

   ∠e = 32°

   ∠d = 69°

   ∠f = 79°

Step-by-step explanation:

       Angle e and 32° are vertical angles, so this means that ∠e = 32° because vertical angles are congruent.

       Next, a straight line is equal to 180°, and angle e is equal to 32°, so we can write the following equation to solve for angle f:

69° + e + f = 180° ➜ 69° + 32° + f = 180° ➜ 101° + f = 180° ➜ f = 79°

       Lastly, angle d and 69° are also vertical angles, so this means that ∠d = 69° because vertical angles are congruent.

The Cartesian equation y = 3x^2 as a polar equation can be write as r(θ) = 3 sec(θ) / (1 + tan²(θ)).

To rewrite the Cartesian equation y = 3x² as a polar equation, we need to use the conversion formulas between Cartesian coordinates (x, y) and polar coordinates (r, θ):

x = r cos(θ)
y = r sin(θ)

Substituting these formulas into the Cartesian equation gives us:

r sin(θ) = 3(r cos(θ))²

Dividing both sides by r and rearranging terms gives us:

r = 3 cos²(θ) / sin(θ)

Using the identity 1 + tan²(θ) = sec²(θ), we can rewrite the equation in terms of tan(θ) and sec(θ):

r = 3 (1 / (1 + tan²(θ))) / (1 / sec(θ))

Simplifying gives us the final polar equation:

r(θ) = 3 sec(θ) / (1 + tan²(θ))

Therefore, the Cartesian equation y = 3x²can be rewritten as the polar equation r(θ) = 3 sec(θ) / (1 + tan²(θ)).
