find the volume of the shaded solid below

Answer: 49.2 feet

Step-by-step explanation:

The given equation h = -16t^2 + 56t represents the height of a football kicked by Lauren as a function of time t in seconds.

In the context of the problem, the vertex of the parabolic function (-16t^2 + 56t) represents the point at which the football reaches its maximum height. The vertex of a parabola is the point where the function reaches its highest or lowest value, and it is given by the coordinates (h, t) in this case.

Interpreting the coordinates of the vertex in context, the h-coordinate represents the maximum height of the football, while the t-coordinate represents the time at which the football reaches that maximum height. So, if we determine the vertex of the given function, we can interpret the maximum height and the time it occurs.

The formula for the x-coordinate (t) of the vertex of a quadratic function in the form y = ax^2 + bx + c is given by t = -b/2a. Comparing this with the given equation, we can identify that a = -16 and b = 56.

Plugging in the values of a and b into the formula, we get:

t = -56 / (2 * -16)

t = -56 / -32

t = 1.75

So, the t-coordinate of the vertex is 1.75 seconds, which represents the time at which the football reaches its maximum height.

To find the h-coordinate of the vertex, we can substitute the value of t we found (1.75) into the given equation:

h = -16(1.75)^2 + 56(1.75)

h = -16(3.0625) + 98

h = -48.8 + 98

h = 49.2

So, the h-coordinate of the vertex is 49.2, which represents the maximum height of the football in feet.

In conclusion, the coordinates of the vertex (49.2, 1.75) in the given context represent the maximum height (49.2 feet) of the football and the time (1.75 seconds) at which the football reaches its maximum height after being kicked by Lauren.

If v = 4i and w = 2i + 5i, the angle between the vectors v and w is approximately 47.32 degrees.

To find the angle between two vectors, we can use the dot product formula, which relates the cosine of the angle between the vectors to their dot product and magnitudes. The dot product of two vectors v and w is given by:

v · w = |v| |w| cos(θ)

where |v| and |w| are the magnitudes of the vectors, and theta is the angle between them.

In this case, we are given the vectors v = 4i and w = 2i + 5j. We can compute their dot product as:

v · w = (4i) · (2i + 5j) = 8 + 0 = 8

We can also compute the magnitudes of the vectors as:

|v| = √((4² + 0²)) = 4

|w| = √((2² + 5²)) = √(29)

Substituting these values into the dot product formula, we get:

8 = 4 √(29) cos(θ)

Solving for cos(θ), we get:

cos(θ) = 2 / √(29)

Taking the inverse cosine of both sides, we get:

θ = cos⁻¹(2 / √(29)) = 47.32 degrees

The exact values of x for x² - 8x - 5 = 0 are x = 4 + √21 or x = 4 - √21

To solve for x in the equation x² - 8x - 5 = 0, we can use the quadratic formula, which is:

x = (-b ± √(b² - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.

Using this formula, we can identify the values of a, b, and c in the equation x² - 8x - 5 = 0.

Here, a = 1, b = -8, and c = -5.

Substituting these values into the formula, we get:

x = (-(-8) ± √((-8)² - 4(1)(-5))) / 2(1)

Simplifying this expression, we get:

x = (8 ± √(64 + 20)) / 2

x = (8 ± √84) / 2

Now, we can simplify the square root of 84 as 2√21:

x = (8 ± 2√21) / 2

We can further simplify this expression by factoring out 2 from the numerator:

x = 2(4 ± √21) / 2

Canceling out the 2s, we get:

x = 4 ± √21

Answer: D. y=1/2x+1

Step-by-step explanation:

For every 2 x values on the table, y increases only by 1. To find the slope of the table you can also use the slope formula with two points. y2-y1/x2-x1=m

For example,

(4, 3) & (6, 4)

The first point has the ordered pair of x1 and y1. The second point is the ordered pair of x2 and y2. Plug the numbers into the equation and you'll find the slope.

So, 4-3 / 6-4 = 1/2.

Now that we have the slope we can use the point-slope formula to find the y-intercept. y-y1=m(x-x1)

This formula only requires 1 point from the table and the slope so you can use any point, I'll use (4,3). After that, you plug in your numbers into the equation and solve for y.

y-3=1/2(x-4)

y-3=1/2x-2

Add 3 to both sides

y=1/2x+1

And you're done :)

The value of x in the similar triangle is 2 units.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Therefore, let's use the ratio to find the side length of x in the triangle.

Hence, the right angle triangle FHJ is similar to the right angle triangle GFJ. Using the similarity ratios,

GH / GF = GF / GJ

Hence,

GH = 9

GF = 3√11

GJ =  x + 9

9 / 3√11 = 3√11 / x + 9

cross multiply

9(x + 9) = (3√11)(3√11)

9x + 81 = 9(11)

9x + 81 = 99

9x = 99 - 81

9x = 18

divide both sides by 9

Answer:

the volume of the prism at the right is 56.7 cm³

Step-by-step explanation:

To find the volume of the prism at the right, we need to first find the area of the base, which is a triangle. The area of a triangle is given by A=21​bh

where A

is the area, b

is the base, and h

is the height of the triangle.

The base of the triangle is 4.2 cm and the height of the triangle is 3 cm. So, we can plug these values into the formula and get:

A=21​(4.2)(3)

A=6.3 cm2

Now that we have the area of the base, we can multiply it by the height of the prism, which is 9 cm. This will give us the volume of the prism:

V=B×h

V=6.3×9

V=56.7 cm3

Originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

Originality refers to the quality of being unique, new, and innovative. It involves creating something that has not been seen or experienced before. The best description of originality is that it is having a low probability and being unique.

An original idea, product, or work of art is something that has not been copied or imitated from others. It represents a new perspective or approach that can offer a fresh insight into a problem or challenge. Originality requires a high level of creativity, imagination, and inspiration, as well as a willingness to take risks and explore new possibilities.

Nonobviousness is also an important factor in originality. It means that the idea or invention is not something that would be obvious to someone skilled in the same field or industry. In other words, an original idea should not be something that could be easily predicted or anticipated.

Special or interesting are also characteristics of originality, but they are not sufficient to define it. An idea or product can be special or interesting without being truly original. For example, a new flavor of ice cream may be interesting, but it may not be original if it has already been created by someone else.

Convergent thinking, on the other hand, involves finding a single solution to a problem. It is the opposite of divergent thinking, which involves generating multiple ideas and possibilities. Convergent thinking is important for finding effective solutions to problems, but it is not the same as originality.

In conclusion, originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

Answer:

(a) Christine will have to pay $400 in total interest.

(b) Christine will have to repay a total of $4400, including interest.

Step-by-step explanation:

(a) The interest charged on the loan is calculated as simple interest, which means that it is calculated as a percentage of the principal amount for each year. The interest rate is 5%, and the principal amount is $4000.

The total interest charged on the loan is:

Interest = Principal x Rate x Time

Interest = $4000 x 0.05 x 2

Interest = $400

Therefore, Christine will have to pay $400 in total interest.

(b) The total repayment amount is the sum of the principal and the interest charged on the loan.

Total repayment amount = Principal + Interest

Total repayment amount = $4000 + $400

Total repayment amount = $4400

Therefore, Christine will have to repay a total of $4400, including interest.

Answer:

Since the figures are similar, their corresponding side lengths are proportional.

Let x be the scale factor between the larger and smaller figures. Then, the volume of the larger figure is x^3 times the volume of the smaller figure.

We can set up an equation to solve for x:

2500 = x^3 * 160

Divide both sides by 160:

x^3 = 2500/160

x^3 = 15.625

Take the cube root of both sides:

x = 2.5

So, the scale factor between the larger and smaller figures is 2.5.

Since surface area is proportional to the square of the scale factor, we can set up another equation to solve for the surface area of the smaller figure:

S.A. of smaller figure / S.A. of larger figure = (scale factor of smaller figure)^2 / (scale factor of larger figure)^2

Solving for the surface area of the smaller figure:

S.A. of smaller figure / 1400 = 2.5^2 / 1^2

S.A. of smaller figure / 1400 = 6.25

S.A. of smaller figure = 6.25 * 1400

S.A. of smaller figure = 8750

Therefore, the surface area of the smaller figure is 8750 meters squared.
