The given functions are

f(x) = x^2 - 5

g(x) = 3x - 1

To find 2g(f(- 5)), we would first find f(- 5)

To find f(- 5), we would substitute x = - 5 into f(x) = x2 - 5. It becomes

f(- 5) = (- 5)^2 - 5

f(- 5) = 25 - 5

f(- 5) = 20

Then, we would substitute f(- 5) = 20 into g(x) = 3x - 1

Thus,

g(f(- 5) = 3*20 - 1

g(f(- 5) = 60 - 1

g(f(- 5) = 59

Therefore,

2g(f(- 5)) = 2 * 59 = 118

Let's call the speed of the river "r". The speed of the current in the downstream direction is 9 + r mph, and the speed of the current in the upstream direction is 9 - r mph. The time it takes to travel downstream and return upstream is the same, so we can set up the following equation:

(32 miles) / (9 + r mph) + (32 miles) / (9 - r mph) = 9 hours

We can simplify this equation by converting hours to minutes and miles to feet, and then simplify further by multiplying both sides of the equation by the denominators:

32 * 60 * (9 + r) + 32 * 60 * (9 - r) = 9 * 60 * (9 + r) * (9 - r)

Expanding the right side of the equation and simplifying:

32 * 60 * (9 + r) + 32 * 60 * (9 - r) = 810 * (9 + r) * (9 - r)

Expanding the left side of the equation and simplifying:

32 * 60 * 9 + 32 * 60 * r + 32 * 60 * 9 - 32 * 60 * r = 810 * (9 + r) * (9 - r)

Combining like terms and solving for r:

32 * 60 * 9 * 2 = 810 * (9 + r) * (9 - r)

96720 = 810 * (9 + r) * (9 - r)

Dividing both sides by 810:

119 = (9 + r) * (9 - r)

Expanding the right side of the equation:

119 = 81 - r^2

Adding r^2 to both sides of the equation:

119 + r^2 = 81

Subtracting 81 from both sides of the equation:

38 + r^2 = 0

Taking the square root of both sides of the equation:

r = ± sqrt(38)

Since r is the speed of the current, it must be a positive value, so we take the positive square root:

r = sqrt(38) mph

The speed of the river (current speed) is approximately 6.17 mph.

Square Area = side x side = 3x3 = 9

Rectangle Area = side x side= 7x3= 21

9 + 21 = 30 square inches

Answer:

30 square inches

Step-by-step explanation:

   \(\boxed{\text{\bf Area of rectangle = length *width}}\)

Rectangle1:

     Area = 6 * 3

              = 18 square inches

Rectangle2:

Area = 4 * 3

          = 12 square inches

Area of the figure = area of rectangle1 + area of rectangle2

                             = 18 + 12

                             = 30 square inches

Using the lowest common factor of the shuttles' run times, they will depart again for the campus simultaneously at 10.25 A.M.

We can use the lowest common factor (LCM) of their run time to determine when they depart again for the campus.

The lowest common factor of 30 and 20 is 60 because both 30 and 20 can divide 60 evenly without a remainder, showing that it takes 60 minutes for the two shuttles to depart for the campus at the same time.

We can conclude that every 60 minutes or hour, the two shuttles simultaneously depart for the campus.  Every hour, the shuttle departing from Ball Hall completes 2 runs, while the shuttle departing from Lot A completes 3 runs.

Thus, using the lowest common factor, the next time both shuttles will depart for the campus at the same time is 10:25 A.M.

The orthogonal projection of vector v onto vector w in R^3 is (-54/14, -159/70, -159/35).

To find the orthogonal projection of v onto w, we need to calculate the scalar projection of v onto w and multiply it by the unit vector of w. The scalar projection of v onto w is given by the formula:

proj_w(v) = (v⋅w) / (w⋅w) * w

where ⋅ denotes the dot product.

Calculating the dot product of v and w:

v⋅w = (-7)(-5) + (6)(-3) + (-6)(-6) = 35 + (-18) + 36 = 53

Calculating the dot product of w with itself:

w⋅w = (-5)(-5) + (-3)(-3) + (-6)(-6) = 25 + 9 + 36 = 70

Now, substituting these values into the formula, we have:

proj_w(v) = (53/70) * (-5,-3,-6) = (-54/14, -159/70, -159/35)

Therefore, the orthogonal projection of v onto w is (-54/14, -159/70, -159/35).

In simpler terms, the orthogonal projection of v onto w can be thought of as the vector that represents the shadow of v when it is cast onto the line defined by w. It is calculated by finding the component of v that aligns with w and multiplying it by the direction of w. The resulting vector (-54/14, -159/70, -159/35) lies on the line defined by w and represents the closest point to v along that line.

Answer:

The critical region is F >F ₀.₀₁ (2,18) = 6.01

Step-by-step explanation:

For 1 way ANOVA the degrees of freedom Between Samples would 2 and within Samples would be 18 .

Alpha is given  to be = 0.01

v1 = k-1 and v2 = n-k

Where k is the number of rows and n is the total number of values

v1= 3-1= 2   and v2 = 21-3= 18

So if we look up the table we find the values of the critical region to be 6.01

Hence the critical region is less and equal to 6.01

The critical region is F >F ₀.₀₁ (2,18) = 6.01

The inequality that represents p, the number of people the theater can seat is p ≤ 25

From the question, we have the following parameters that can be used in our computation:

A movie theater can seat a maximum of 25 people

This means that

Maximum =  25 people

In other words, the movie theatre can allow 25 or less people to attend a movie

In inequality, 25 or less means less than or equal to 25

When represented as an inequality expression, we have

≤ 25

Using the variable p, we have

p ≤ 25

Hence, the inequality is p ≤ 25

Answer:

Step-by-step explanation:

For the first bag:

Price of the bag = $12

Number of balls in the bag = 15

Price per ball = Price of the bag / Number of balls

Price per ball for the first bag = $12 / 15 = $0.8

For the second bag:

Price of the bag = $15

Number of balls in the bag = 20

Price per ball = Price of the bag / Number of balls

Price per ball for the second bag = $15 / 20 = $0.75

Comparing the prices per ball, we find that the second bag has a lower price per baseball. Therefore, the second bag offers a better price for individual baseballs compared to the first bag.

Answer:

Step-by-step explanation:

To find out which bag prices individual baseballs lower, we can divide the total cost of each bag by the number of balls in the bag. This will give us the price per ball for each bag.

For the first bag, the price per ball is $12 / 15 = $0.80.

For the second bag, the price per ball is $15 / 20 = $0.75.

Therefore, the second bag prices individual baseballs lower.

Your answer doesnt say how much the beetle wighs, probably the grasshopper though

Step-by-step explanation:

The given statement "The 55th percentile is less than 27 hours" is false.

The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

The data is given in the question, as follows:

Mean = 32 hours

Median = 28.2 hours

8th percentile = 17 hours

Number of families who turned on the television for 17 hours or less = 24

The given information to estimate the 55th percentile as follows:

Half the families in the sample turned on the television for 28.2 hours or less (since this is the median).

Of the remaining half, 8% turned on the television for 17 hours or less (since this is the 8th percentile), which leaves 42% of the families who turned on the television for more than 28.2 hours but less than 17 hours.

Therefore, we can estimate the 55th percentile to be around the middle of this range, which is approximately 28.2 + 0.42(32-28.2) = 30.56 hours.

Since 30.56 hours is greater than 27 hours, we can conclude that the statement "The 55th percentile is less than 27 hours" is false.
