How to find 2 irrational no.s between 2016 and 2017

Answer:

s = ∛( 1953.125 cm³ ) = 12.5 cm

Step-by-step explanation:

The volume of a cube is V = s³, where s represents the length of one edge.

Here, V = s³ = 1953.125 cm³, and we need to solve for s.  Do this by taking the cube root of both sides:

s = ∛( 1953.125 cm³ ) = 12.5 cm

y=-2x+3 in slope-intercept form

3 is the y-intercept and -2 is the slope

Answer:

2x - y + 3 = 0

Step-by-step explanation:

The formula used to find the equation is:

[tex]y-y_1= \frac{(y_2-y_1)}{(x_2-x_1)} (x-x_1)[/tex]

Here, (x₁, y₁) = (0, 3)

and (x₂, y₂) = (1, 1)

Putting all values in above formula,

[tex]y-3= \frac{(1-3}{(1-0)} (x-0)[/tex]

⇒  [tex]y - 3 =\frac{-2}{1}x[/tex]

⇒ y - 3 = 2x

⇒ 2x - y + 3 = 0

which is the requires equation.

Answer:

2.3%

Step-by-step explanation:

The formula to convert x into z distribution is

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Where z is the test statistic

x is what we are looking for (in this case 37)

[tex]\mu[/tex] is the mean (in this case, it is 25)

[tex]\sigma[/tex] is the standard deviation (we have 6)

Plugging these into the formula, we get:

[tex]z=\frac{x-\mu}{\sigma}\\z=\frac{37-25}{6}\\z=2[/tex]

Thus we can say we want [tex]P(z\geq 2)[/tex]

Note: [tex]P(z\geq a)=1-P(z\leq a)[/tex]

The table given is for any  z where [tex]P(z\leq a)[/tex]

Thus, now we have:

[tex]P(z\geq 2)\\=1-P(z\leq 2)\\=1-0.9772\\=0.0228\\[/tex]

0.0228 into percentage is 0.0228 * 100 = 2.28%

Rounded, we get 2.3%

Third answer choice is right.

Graph A.

Step-by-step explanation:

We will try to understand the graph plotted for the change in temperature for whole day.

In the morning, temperature starts out around 50°F. As the day goes on, the temperature rises first slowly- Slope of the first line will be less.

Then temperature rises more quickly - Slope of the second line will be more than first line.

It stays constant for an hour- third line will be parallel to the x-axis for one hour gap.

Then the temperature dropped down slowly - Last line of the graph will go down.

By the understanding we made for the graph we find graph A is the answer.

[tex]area = \frac{1}{2} (x + 3)(x + 5) = 24 \\ [/tex]

then

[tex](x + 3)(x + 5) = 48[/tex]

[tex] {x}^{2} + 8x + 15 = 48 [/tex]

[tex] {x}^{2} + 8x + 15 - 48 = 0 \\ {x}^{2} + 8x - 33 = 0[/tex]

[tex] {x}^{2} - 3x + 11x - 33 = 0 \\ x(x - 3) + 11(x - 3) = 0 \\ (x - 3)(x + 11) = 0[/tex]

hmmm was going to do a quick mockup, but it might be too wide, so let's nevermind that piece.

so let's see, the center of this ellipse is at (3,1), and a focus point is at (8,1), notice, the y-coordinate is the same, meaning the distance between those two points is "c", which is 5, so c = 5.

We also know that the directrix is x = 36.8, well, that's a vertical line, if the line is vertical, that means the ellipse is running perpendicular to that, namely it has a major axis over the x-axis, so is horizontal.

Step-by-step explanation:

Answer= .2 probability

Explanation: Since there is a total of 10 marbles, and 2 are red, you would divide the red marbles (2) out of the total marbles (10) which would get u .2. Since it’s asking for probability, we would keep .2 a decimal.

The probability of randomly picking a red marble from the bag is 2 out of 10, or 0.2 when expressed as a decimal, which equates to a 20% chance.

The subject of the question you asked is mathematics, specifically probability. In order to calculate the probability of an event happening, you divide the number of successful outcomes by the total number of outcomes. In this case, the successful outcome would be picking a red marble.

The total number of marbles in the bag is 5 (green) + 3 (blue) + 2 (red) = 10. The successful outcomes are 2 (the red marbles). Therefore, the probability of picking a red marble is 2/10 or 0.2.

To put this as a percentage, you multiply by 100, so the probability is 20%. This means that if you pick a marble out at random, there is a 20% chance that it will be red. This is assuming that after each pick, you put the marble back in the bag, also known as picking 'with replacement'.

The surface area of the triangular prism is 1950 square inches, computed by summing the areas of its constituent triangles and rectangles.

Surface area refers to the measure of the total area that the surface of an object occupies. It is a crucial geometric concept that varies for different shapes and dimensions in geometry, encompassing diverse forms like spheres, cubes, cuboids, cones, and cylinders. Each geometric shape possesses unique formulas for calculating its surface area.

Considering the provided net for a triangular prism with side lengths a, b, and c, and altitude d, the surface area is computed by summing the areas of its constituent shapes – two triangles and three rectangles. The formula for the total surface area is given as:

Total Surface Area = Surface Area of Triangle + Surface Area of Rectangle

Detailed calculations involve substituting the given values for side lengths and altitude into the formulas for the surface area of a triangle and a rectangle. For the triangular prism described, the total surface area is determined as:

Total Surface Area = d * a + b * a + 2 * c * b

Substituting the given values (d = 20, a = 44, b = 14, and c = 30), the calculation yields:

Total Surface Area = (22 * 45) + (12 * 45) + 2 * (30 * 14) = 1950

Therefore, the surface area of the given figure is 1950 square inches.

Final answer:

The surface area of the triangular prism is calculated by adding the areas of the two triangular faces and three rectangular faces. Upon calculation, the areas of two triangles are 600 square inches, and the rectangles are 900 and 280 square inches for sides a and b, respectively. However, none of the provided answer choices match the calculated surface area of 1780 square inches.

Explanation:

To find the surface area of a triangular prism, we need to find the area of all its faces. We have two triangular faces and three rectangular faces. The area of each triangular face is calculated using the formula A = bh/2, where b is the base and h is the height. Since side c is 30 inches and the altitude d is 20 inches, the area of one triangular face is:

A triangle = (c x d) / 2

= (30 inches x 20 inches) / 2

= 600 / 2

= 300 square inches

Since there are two triangular faces, we double this to get 600 square inches for both.

The rectangular faces consist of the sides a, b, and c. Their areas are a x d, b x d and c x d, respectively. So we calculate:

Side a: 45 inches x 20 inches = 900 square inches

Side b: 14 inches x 20 inches = 280 square inches

Side c (already computed as part of triangular faces)

Sum the areas of all these faces to get the total surface area:

Total surface area = (Area of triangles) + (Area of rectangles)

= 600 square inches (triangles) + 900 square inches (side a) + 280 square inches (side b)

= 1780 square inches

The correct answer must include the area of both triangular faces and all three rectangular faces. Since none of the given options match the computed total surface area, it's possible there may have been an error in the provided options or in the dimensions given for the prism.

m = 2.25

Step-by-step explanation:

The slope of the function is equal to its rate of change between two points.

For example, for a couple of points [tex](x_1, y_1),\ (x_2, y_2)[/tex]

The slope is:

[tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex]

In this problem we have the following points

1.(2, 8.50) , 2. (5, 15.25), 3. (8, 22.00) , 4. (12, 31.00)

We calculate the slope between the first two points

[tex]m =\frac{15.25-8.50}{5-2}=2.25[/tex]

We calculate the slope between the points 3 and 4

[tex]m =\frac{31-22}{8-4}=2.25[/tex]

We calculate the slope between the points 2 and 3

[tex]m =\frac{22-15.25}{8-5}=2.25[/tex]

The slope is always the same. Therefore m is constant and the fution is a line of slope m = 2.25

Answer:

Step-by-step explanation:

1. We aren't worried about the area of the base, so the area is the area of the 4 triangles.  Each triangle has an area of half the base times the height.

A = 4 (½ bh)

A = 2 bh

Given b = 6 and h (the height of the triangle, not the pyramid) = 5:

A = 2 (6) (5)

A = 60 ft²

2. This time, we want to include the area of the rectangular base, so:

A = b₁b₂ + 2 (½ b₁h₁) + 2 (½ b₂h₂)

A = b₁b₂ + b₁h₁ + b₂h₂

Given b₁ = 78 m, b₂ = 50 m, h₁ = 52 m, and h₂ = 60 m:

A = (78) (50) + (78) (52) + (50) (60)

A = 10,956 m²

Step-by-step explanation:

The augmented matrix for the system of three equaitons is

[tex]\left(\begin{array}{ccccc} 3&-4&-5&|&-27\\5&2&-2&|&11\\5&-4&4&|&-7\end{array}\right)[/tex]

Multiply the first row by 5, the second row by -3 and add these two rows:

[tex]\left(\begin{array}{ccccc} 3&-4&-5&|&-27\\0&-26&-19&|&-168\\5&-4&4&|&-7\end{array}\right)[/tex]

Subtract the third row from the second:

[tex]\left(\begin{array}{ccccc} 3&-4&-5&|&-27\\0&-26&-19&|&-168\\0&6&-6&|&18\end{array}\right)[/tex]

Divide the third row by 6:

[tex]\left(\begin{array}{ccccc} 3&-4&-5&|&-27\\0&-26&-19&|&-168\\0&1&-1&|&3\end{array}\right)[/tex]

Now multiply  the third equation by 26 and add it to the second row:

[tex]\left(\begin{array}{ccccc} 3&-4&-5&|&-27\\0&-26&-19&|&-168\\0&0&-45&|&-90\end{array}\right)[/tex]

You get the system of three equations:

[tex]\left\{\begin{array}{r}3x-4y-5z=-27\\-26y-19z=-168\\-45z=-90\end{array}\right.[/tex]

From the third equation

[tex]z=\dfrac{90}{45}=2.[/tex]

Substitute z=2 into the second equation:

[tex]-26y-19\cdot 2=-168\\ \\-26y-38=-168\\ \\-26y=-168+38=-130\\ \\y=\dfrac{130}{26}=5.[/tex]

Now substitute z=2 and y=5 into the first equation:

[tex]3x-4\cdot 5-5\cdot 2=-27\\ \\3x-20-10=-27\\ \\3x-30=-27\\ \\3x=-27+30=3\\ \\x=1.[/tex]

The solution is (1,5,2)

The correct answer is option d (1, 5, 2).

To solve the system of equations, let's write the augmented matrix and perform row operations to get it into reduced row-echelon form (RREF). The system of equations is as follows:

3x−4y+5z (1)

5x+2y−2z  (2)

5x−4y+4z  (3)

The augmented matrix for this system is:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\5&2&-2&|11\\5&-4&4&|7\end{array}\right][/tex]

Now, let's perform row operations to get the reduced row-echelon form:

Subtract 5 times the first row from the second row:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\0&22&-27&|-134\\5&-4&4&|7\end{array}\right][/tex]

Subtract 5 times the first row from the third row:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\0&22&-27&|-134\\0&16&-21&|-118\end{array}\right][/tex]

Multiply the second row by 8/11:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\0&1&-8/11&|-67/11\\0&16&-21&|-118\end{array}\right][/tex]

Subtract 16 times the second row from the third row:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\0&1&-8/11&|-67/11\\0&0&5/11&|10/11\end{array}\right][/tex]

Multiply the third row by 11/5:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\0&1&-8/11&|-67/11\\0&0&1&|2\end{array}\right][/tex]

Add 4/11 ​times the third row to the second row:

[tex]\left[\begin{array}{ccc}3&-4&5&|27\\0&1&0&|1\\0&0&1&|2\end{array}\right][/tex]

Add 4 times the third row to the first row:

[tex]\left[\begin{array}{ccc}3&-4&0&|35\\0&1&0&|1\\0&0&1&|2\end{array}\right][/tex]

Add 4 times the second row to the first row:

[tex]\left[\begin{array}{ccc}3&0&0&|39\\0&1&0&|1\\0&0&1&|2\end{array}\right][/tex]

Now, we can read off the solutions:

3x=39⇒x=13

y=1

z=2

So, the correct answer is (d) (1,5,2).
