Step-by-step explanation:

I added a photo of my solution

Answer:

Answer is -10

Step-by-step explanation:

The approximate volume of the remaining solid is option (b) 77 cubic inches

The volume of the rectangular prism is given by

V_rectangular prism = base area x height = 4 x 4 x 6 = 96 cubic inches

The volume of the cylinder is given by

V_cylinder = π x r^2 x h = π x 1^2 x 6 = 6π cubic inches

To find the volume of the remaining solid, we need to subtract the volume of the cylinder from the volume of the rectangular prism

V_remaining solid = V_rectangular prism - V_cylinder = 96 - 6π ≈ 77 cubic inches (rounded to the nearest whole number)

Therefore, the correct option is (b) 77 cubic inches

By definition, direct variation takes the following form:

y=kx

Where k is the proportionality constant.

You can find k given the information in the problem:

7=3k

k=3/7

You can now find y when x=7 as follows:

y=(7*3)

Values can be substituted. Then:

y=(7*7)/3

y=49/3

If y varies directly from x, then the value of y = 49/3 when x = 7.

If y varies directly from x, we can write its relationship in the form of the equation below :

y = m*x

Where m is the slope of the line on the graph.

From the given data:

y=7

x=3,

We can substitute these values in the above equation and find m :

7 = m*3

m = 7/3

So, the equation can also be written as follow:

y = 7/3 x

Finding y when x=7, then substituting the x value in the above equation we get:

y = (7/3)*(7)

y = 49/3

Step-by-step explanation:

Answer:

See below, please.

Step-by-step explanation:

Using the zero product property, we can set each factor equal to zero and solve for x:

(x² - 9)(x + 4) = 0

(x² - 9) = 0 or (x + 4) = 0

For the first factor, we can factor it further as the difference of squares:

(x + 3)(x - 3) = 0

So, either (x + 3) = 0 or (x - 3) = 0, giving us:

x = -3, x = 3, or x = -4

Therefore, the values of x for which (x² - 9)(x + 4) = 0 are -3, 3, and -4.

Without the travelling cost being $8, Ani made a total of $45 and she made 15 animal balloons.

We know that the total cost Ani charges for travelling is $53

and the total amount Ani made at the party = $53

therefore, first to find the number of balloons she made we need to subtract the travelling cost from the total amount she made:

= 53 - 8 = 45

therefore, now we know that Ani made a total amount $45 from balloons alone:

also, we know that each balloon costs $3 each therefore we need to divide $45 by 3, we get 15,

hence, we can say that Ani made a total of 15 animal balloons for the party.

By the 46th day, there are 400 water lilies in the pond. the estimate you made: a). close to 46 (or exactly right) because it was estimated well.

We know that the regression equation is: y = 3.915(1.106)ˣ and that the pond can hold 400 water lilies.

y = 3.915(1.106)ˣ

Here, y is equal to the number of water lilies the pond can hold.

So, y = 400

And,  x is the required time taken.

So,

400 = 3.915(1.106)ˣ

⇒ (1.106)ˣ = 400/3.915    

⇒ (1.106)ˣ = 102.17

Taking logarithm on both sides, we get

log (1.106)ˣ = log (102.17)

⇒ x log (1.106) = log (102.17) .............. [log aˣ = x loga]

⇒ x = [log (102.17)/log (1.106)]

The probability that a randomly selected case will have a score beyond either +1.00 or -1.00 standard deviation of the mean depends on the type of distribution and the area under the curve beyond these values.

Assuming a normal distribution, approximately 68% of the cases fall within one standard deviation from the mean, and approximately 32% of the cases fall beyond either +1.00 or -1.00 standard deviation of the mean.

To calculate the probability of a randomly selected case falling beyond either +1.00 or -1.00 standard deviation of the mean, we need to calculate the area under the curve beyond these values. Since the distribution is symmetric, we can calculate the area on one side of the mean and multiply it by 2.

Using a standard normal distribution table or calculator, we can find the area under the curve beyond +1.00 standard deviation from the mean as 0.1587 and the area under the curve beyond -1.00 standard deviation from the mean as 0.1587.

Therefore, the total probability of a randomly selected case falling beyond either +1.00 or -1.00 standard deviation of the mean is 0.1587 + 0.1587 = 0.3174, which is approximately 32%.

Hence, the correct option is (c) 3174.

The average miles per hour that John and his family travel is 55 mph.

American drivers now log a total of 14,263 miles in a single year on average. Around 1,200 miles are driven per month on average, according to this information.

We must divide the whole distance travelled by the total time taken by John and his family in order to determine their average miles per hour:

Total distance x Total time equals average speed.

In this instance, their total journey distance was 137.5 miles, and their total travel duration was 2.5 hours. Hence, we can enter the following values into the formula:

Average speed = 137.5 miles / 2.5 hours

137.5 divided by 2.5 results in:

Average speed is 55 miles per hour.

Step-by-step explanation:

To find the dimensions of the box, we need to solve for the value of x in the expressions given for its length, width, and height.

The volume of a box is given by multiplying its length, width, and height, so we can write:

V = (x+8) * x * (x-2)

Expanding the expression, we get:

V = (x^3 + 6x^2 - 16x)

We know that the volume of the box is measured in cubic feet, so we can assume that V is a positive value. Therefore, we can set V equal to some positive number, such as 1000 or 2000, and solve for x using algebraic techniques such as factoring or the quadratic formula.

For example, if we set V = 1000, we can write:

1000 = x^3 + 6x^2 - 16x

Simplifying and rearranging the terms, we get:

x^3 + 6x^2 - 16x - 1000 = 0

Using a graphing calculator or other mathematical software, we can find that the real solution to this equation is approximately x = 10.5.

Therefore, the dimensions of the box are:

- Length: x+8 = 18.5 feet

- Width: x = 10.5 feet

why it is?

Let's assume that the length of the rectangular garden is L and the width is W. Let the width of the walkway be x.

a. The area of the rectangular garden is L x W. The combined area of the garden and the walkway is the area of the larger rectangle formed by the outer boundary of the walkway. The length of this larger rectangle is (L + 2x) and the width is (W + 2x). Therefore, the polynomial that represents the combined area of the garden and the walkway is:

(L + 2x)(W + 2x)

Expanding this expression, we get:

LW + 2Lx + 2Wx + 4x²2

So, the polynomial that represents the combined area of the garden and the walkway is LW + 2Lx + 2Wx + 4x²2.

b. If the width of the walkway is 4 feet, then x = 4. Substituting this value in the polynomial we obtained in part (a), we get:

LW + 2L(4) + 2W(4) + 4(4)²2

The total derivative of a function is not necessarily one-to-one. The total derivative represents the change in a function with respect to all of its input variables.

If a function has multiple input variables, the total derivative is a matrix, called the Jacobian matrix, whose entries represent the partial derivatives of the function with respect to each input variable.

A function with a non-invertible Jacobian matrix is not one-to-one, since multiple input values can result in the same output value. For example, consider the function f(x,y) = (x^2, y^2). The total derivative of f is given by the Jacobian matrix:

| 2x 0 |

| 0 2y|

This matrix is non-invertible when x=0 or y=0, since it has a determinant of zero. Thus, the function f is not one-to-one when x=0 or y=0.

In terms of polynomials, the total derivative is important for determining whether a polynomial has multiple roots. A root of a polynomial is a value of the input variable that causes the polynomial to equal zero. If a polynomial has multiple roots, it is not one-to-one, since different input values can result in the same output value.

The total derivative of a polynomial can be computed using the power rule of differentiation. For example, consider the polynomial p(x) = x^3 - 6x^2 + 11x - 6. The total derivative of p with respect to x is:

p'(x) = 3x^2 - 12x + 11

If p'(x) has multiple roots, then p(x) has multiple roots as well. In this case, p'(x) has roots at x=1 and x=11/3, so p(x) has multiple roots at x=1 and x=3. Thus, the total derivative is useful for identifying when a polynomial is not one-to-one.
