Mike's claim that (5,28.6) is a point on the exponential function g(x) is incorrect

The points are given as:

(3,6.5) and (4,17.55)

Calculate the rate of change using:

r = y4/y3

This means that:

r = 17.55/6.5

r = 2.7

So, the next point on the graph is:

Next point = 2.7 * y4

Substitute 17.55 for y4

Next point = 2.7 * 17.55

Evaluate

Next point = 47.39

This means that the next point on the graph is (5,47.99)

Hence, Mike's claim that (5,28.6) is a point on the exponential function g(x) is incorrect

The number of zeroes in the product of any nonzero whole number less than 10 and 500 is at least 2, and hence, may be 3 in some cases.

The non-zero whole numbers which are less than 10 ranges over the integers; 1, 2, 3, 4, 5, 6, 7, 8, 9.

Hence, the numbers as indicated above when multiplied by 500 in a bid to determine the required products have varying number of zeroes from 500 to 4500 at 500 intervals.

It therefore follows that for the odd numbers, their products and 500, yield a number with 2 zeroes while that of even numbers and 500, yields 3 zeroes.

The proportion of rural residences with at least three cars or trucks is 0.105.

Here we are given the data on a random sample of Ohio voters.

Here we need to find the proportion of rural residents that own at least 3 cars or trucks.

Here we are already provided with the data that would be required to find the given information.

The type of community the voters belong to has been segregated here column-wise, while the number of cars or trucks owned by them has been segregated row-wise.

Hence first we will locate the rural community column. It is the seconf column of the table.

Then we will see that the number of voters with three or more cars or trucks is given in the 4th column.

Hence the number of rural residents with 3 or more cars or trucks is 335.

Since nothing has been given, we will assume that the proprotion is with the grand total of voters sampled. This we will get from the last cell of the table which is 3200

Hence to get the required proportion we will divide the no. of rural residents with 3 or more vehicles with that of grand total to get

335/3200

= 0.105

Answer: True

Step-by-step explanation:    

Answer:

a - 8

Step-by-step explanation:

1/2 a - 4

if we scale both numbers by the same factor, we will be creating an equivalent expression.

So, let's say we multiply the equation by 2.

1/2 a (2) = 1 a = a

-4 (2) = -8

One equivalent expression would be

a - 8

[If you want to test this out, try plugging in any number for a. For example, if you plug in 10...

1/2 of 10 = 5, 5 - 4 = 1

1 times 10 = 10, 10 - 8 = 2

These answers are the same scaled as the original equation, the answer for the first expression is multiplied by 2 to get the second expression]

Answer: as per question statement

we need to set up an equation first

p(t)=1200e(0.052*t)

they have given that it is relative to 1200 that means it starts to increase from 1200 at t=0 initially 1200 bacteria were present

we need to find population at t=6

we need to plug t=6 in p(t).

I would usually do a guesstimate of this. For example, if I had to plot 0.5 somewhere, I would do it between the 0 and the 1 because the number on the left is a 0, and it's halfway to reaching 1.

Step-by-step explanation:

Answer:

A = 20

B = 12.5

C = 10.2

Step-by-step explanation:

A = (10 + 20 + 30)/3 = 20

B = (5 + 10 + 15 + 20) = 12.5

C = (1 + 5 + 10 + 15 + 20) = 10.2

  The option D is the correct answer.

a. They are adjacent angles: Adjacent angles are angles that share a common side and vertex, but do not overlap. It is possible for two angles to be supplementary and adjacent, but it is not always the case. Therefore, option a is not the correct answer.

b. They are congruent angles: Congruent angles have the same measure. Two angles that are supplementary to the same angle can have different measures, so option b is not the correct answer.

c. They are complementary angles: Complementary angles are two angles that add up to 90 degrees. Since two angles that are supplementary to the same angle add up to 180 degrees, they cannot also be complementary. Therefore, option c is not the correct answer.

d. They are congruent supplementary angles: Congruent supplementary angles have the same measure and add up to 180 degrees. This is the correct answer because if two angles are supplementary to the same angle, their measures must be equal in order for their sum to be 180 degrees. Therefore, option d is the correct answer.

To summarize, if two angles are supplementary to the same angle, they are congruent supplementary angles because their measures are equal and add up to 180 degrees.

The equation of the rational function that fits the given criteria is F(x) = (x+5)(x-1)/[(x-2)(x+3)].

A rational function that has zeros of x=-5 and x=1, does not exist at x=2 and x=-3, and has an end behavior that tends toward y=3 would look like the following equation:

F(x) = (x+5)(x-1)/[(x-2)(x+3)]

The numerator of this function includes the zeros, or the values of x that make the function equal to zero. The denominator includes the values of x that make the function not exist, or where the function has vertical asymptotes.

The end behavior of this function is determined by the leading coefficients and degrees of the numerator and denominator. Since they are both of degree 2, the end behavior will be a horizontal asymptote at y=3.

In conclusion, the equation of the rational function that fits the given criteria is F(x) = (x+5)(x-1)/[(x-2)(x+3)].

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -

h(t) = 5 + 25t - 16t²

where [t] is the time in seconds.

[A] -

At h = 4ft, we can write -

4 = 5 + 25t - 16t²

- 16t² + 25t + 1 = 0

On solving, we get -

t = 1.602 seconds

[B] -

We have -

h(t) = 5 + 25t - 16t²

For maximum height -

dh/dt = 0

d/dt(5 + 25t - 16t²) = 0

The correct answer is x = 36/55.

To solve the equation \(3 2/3 \times  x = 2 2/5,\) .  
1. Convert the mixed numbers to improper fractions:
\((3 \times  3 + 2) / 3 = 11/3 (for 3 2/3)\)
\((2 \times  5 + 2) / 5 = 12/5 (for 2 2/5)\)
So, the equation becomes:
\((11/3) \times  x = 12/5\)
To isolate x, divide both sides by 11/3:
x = (12/5) ÷ (11/3)
When dividing fractions, multiply by the reciprocal of the second fraction:
\(x = (12/5) \times  (3/11)\)
Multiply the numerators and the denominators:
\(x = (12 \times  3) / (5 \times  11)\)

Because they are parallel

Step-by-step explanation:

Since these lines both have a slope of 3, they are parallel and will never touch, therefore they have no solutions.

Using the Rogawski/Adams, we have found  that dy/dx at the point (2, -4) is -1/6.

To find dy/dx at the point (2, -4), we need to differentiate the given equation implicitly with respect to x and then substitute the values x = 2 and y = -4.

The given equation is:

(x + 5)² - 3(2y + 1)² = -98

To differentiate implicitly, we differentiate each term with respect to x:

d/dx[(x + 5)²] - d/dx[3(2y + 1)²] = d/dx[-98]

Applying the chain rule, we have:

2(x + 5)(1) - 6(2y + 1)(2(dy/dx)) = 0

Simplifying this equation, we get:

2(x + 5) - 12(2y + 1)(dy/dx) = 0

Now, we substitute x = 2 and y = -4:

2(2 + 5) - 12(2(-4) + 1)(dy/dx) = 0

2(7) - 12(-7)(dy/dx) = 0

14 + 84(dy/dx) = 0

84(dy/dx) = -14

(dy/dx) = -14/84

(dy/dx) = -1/6

Therefore, dy/dx at the point (2, -4) is -1/6.

The surface area of a triangular prism can be calculated using the formula SA = 2(Ab + At + Atotal), where Ab represents the area of the triangular base and Atotal represents the sum of the areas of all three rectangular faces. The options provided are a) 991c * m^2, b) 1024c * m^2, c) 1400c * m^2, and d) 1984c * m^2.

To calculate the surface area of a triangular prism, we first determine the area of the triangular base. This is found using the formula Ab = (1/2) * base * height, where the base and height are the dimensions of the triangular base. Next, we calculate the area of each rectangular face, which is equal to the product of the length and width of each face. Finally, we sum up the areas of the triangular base and the three rectangular faces to obtain the total surface area of the prism.

Without specific values provided for the base, height, length, and width of the prism, it is not possible to determine the exact surface area. Therefore, none of the given options can be determined as the correct answer without additional information.
