Step-by-step explanation:

An exponential function is a mathematical function of the following form: f ( x ) = a x. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.

The correct answer is B: (1, 10).

To determine which point is also on the graph of the exponential model [tex]\(y = a \cdot b^x\)[/tex], we can use the given points (2, 50) and (3, 250) to set up a system of equations.

For the point (2, 50):

[tex]\[50 = a \cdot b^2\][/tex]

For the point (3, 250):

[tex]\[250 = a \cdot b^3\][/tex]

Dividing the second equation by the first, we get:

[tex]\[\frac{250}{50} = \frac{a \cdot b^3}{a \cdot b^2}\][/tex]

Simplifying:

[tex]\[5 = b\][/tex]

Now that we know [tex]\(b = 5\)[/tex], we can substitute this back into either of the original equations to solve for [tex]\(a\)[/tex]. Using the first equation:

[tex]\[50 = a \cdot 5^2\][/tex]

Solving for \(a\):

[tex]\[a = 50/25 = 2\][/tex]

So, the exponential model is [tex]\(y = 2 \cdot 5^x\)[/tex].

Now we can check which of the given points is on the graph:

- For point (0, 5): [tex]\(y = 2 \cdot 5^0 = 2 \cdot 1 = 2\)[/tex]

- For point (1, 10): [tex]\(y = 2 \cdot 5^1 = 2 \cdot 5 = 10\)[/tex]

- For point (4, 450): [tex]\(y = 2 \cdot 5^4 = 2 \cdot 625 = 1250\)[/tex]

- For point (5, 650): [tex]\(y = 2 \cdot 5^5 = 2 \cdot 3125 = 6250\)[/tex]

The only point that satisfies the exponential model is (1, 10). Therefore, the correct answer is B. (1, 10).

Answer:

V = 523.33 cm^3

Step-by-step explanation:

The volume of a sphere is given by

V =4/3 pi r^3

We know the radius is 5

V = 4/3 (3.14) 5^3

V=523.3333333

Rounding to the hundredths place

V = 523.33 cm^3

Answer:

523.33 cm

Step-by-step explanation:

V= 4/3 pi r3

=4/3 pi (5 cm)3

=4/3 pi (125cm)

=4/3 3.14 (125cm)

=4/3 (392.5)

Answer:

Soil A mean: 71.8

Soil B mean: 72

Soil A MAD: 8.16

Soil B MAD: 5.4

Soil A set is more variable because it has a greater MAD. This feature is also seen in the stem-and-leaf plot, where Soil A set is more spread than Soil B set

Step-by-step explanation:

Soil A | |Soil B  

          |5|9  

5 2 1 1|6|3 9  

  5 1 0|7|0 2 3 6 7 8  

      2 1|8|3  

        0|9|

Soil A mean: (65 + 62 + 61 + 61 + 75 + 71 + 70 + 82 + 81 + 90)/10 = 71.8

Soil B mean: (59 + 63 + 69 + 70 + 72 + 73 + 76 + 77 + 78 + 83)/10 = 72

Soil A MAD: ( |65 - 71.8| + |62 - 71.8| + |61 - 71.8| + |61 - 71.8| + |75 - 71.8| + |71 - 71.8| + |70 - 71.8| + |82 - 71.8| + |81 - 71.8| + |90 - 71.8|)/10 = 8.16

Soil B MAD: ( |59-72| + |63-72| + |69-72| + |70-72| + |72-72| + |73-72| + |76-72| + |77-72| + |78-72| + |83-72| )/10 = 5.4

Answer:

(–∞, 1.5) or A on edge

Step-by-step explanation:

took the test

Over (∞, 1.5), the graph of f(x) = -x² + 3x + 8 is increasing.

A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a,b)| for all a ∈ A, b ∈ B}

It is given that function is

f(x) = -x² + 3x + 8

We know that graph of f(x) is increasing if f’(x) > 0

-2x + 3 > 0

-2x > -3

x < 3/2 or 1.5

Thus, the graph is increasing over (∞, 1.5).

Step-by-step explanation:

Measurements shorter than 1 meter are usually in centimeters and millimeters; for example, the length of a hand or the size of a small worm. Longer measurements such as the length of a street or the distance between towns are in meters or kilometers.

In the metric system, the length measurements shorter than 1 meter include centimeters (cm) and millimeters (mm). To identify which measurements are shorter than 1 meter, we can consider the size or distance involved. Some options include:

On the other hand, measurements that are likely to be equal to or longer than 1 meter might include:

Understanding that 1 meter is roughly the distance from fingertip to fingertip when arms are stretched out to the sides can help visualize the scale when deciding on the appropriate unit for measuring length.

To find the designated sum in an arithmetic series, use the formula (n/2)(a_1 + a_n), where n represents the number of terms, a_1 is the first term, and a_n is the last term.

Explanation:

How to Find the Designated Sum in Arithmetic Series

An arithmetic series is a sequence of numbers in which the difference between consecutive terms is constant. To find the designated sum in an arithmetic series, you can use the formula:

S_n = (n/2)(a_1 + a_n)

Identify the first term (a_1), the number of terms (n), and the common difference (d) of the arithmetic series.

Use the formula a_n = a_1 + (n-1)d to find the value of the last term in the series (a_n).

Substitute the values of a_1, a_n, and n into the formula S_n = (n/2)(a_1 + a_n) to calculate the designated sum of the arithmetic series.

Final answer:

The area of a polygon can be estimated using a grid to count squares, with specific formulae used for regular shapes. Irregular shapes can be broken down into simpler shapes, and the areas summed up, or approximated as areas under a curve using rectangles.

Explanation:

To find the area of a polygon, one approach can be to approximate the area using graph paper. You would place the polygon over a grid and count the number of squares that are completely covered by the polygon. Partial squares would be estimated. For polygons with straight sides like triangles, rectangles, and other regular shapes, you can use specific formulae. For example, the area of a triangle is found using the formula A = wh/2, where 'w' is the base width and 'h' is the height.

To find the area of irregular shapes, the shape can be broken down into a combination of known shapes, then the area for each known shape is calculated and summed up. For instance, if you're finding the area within a curve represented by a graph, you can approximate the area under the curve by summing up the areas of rectangles (or triangles) that fit under the curve.

C = 2πr = 2 x 3.14 x 9 = 56.54867

Answer:

x = -4

y = -2

Step-by-step explanation:

All you need to do is plug in the number given for y into the equation:

-4x + 8y = 0

-4x + 8(-2) = 0

-4x - 16 = 0

Add 16 to both sides:

-4x - 16 = 0

     + 16  + 16

____________

-4x = 16

Finally, divide both sides by -4:

-4x = 16

x = -4

So now you have, x = -4 and y = -2

The product (-1/2) \\cdot (1/2) \\cdot (1/2) simplifies to -1 \\cdot (1/2)^2, which equals -1/4 when written using exponents.

The product of these fractions, (-1/2) \\cdot (1/2) \\cdot (1/2), can be written using exponents. Since we are multiplying the same base, (1/2), we simply add the exponents. The fraction -1/2 can be thought of as (-1) \\cdot (1/2), so it won't affect the exponent but will contribute a negative sign to the product.

To use exponents, we count how many times the base (1/2) is used as a factor: twice. We can express this as (1/2)^2. Combining this with the negative sign from (-1/2), the final expression is -1 \\cdot (1/2)^2, which simplifies to -1/4 because (1/2)^2 = 1/4.
