(a) The function g(x) = -8[tex]x^2[/tex] + 5x - 2 doesn't have two x-intercepts because ac > 0.

(b) The function h(x) = (-1/3)[tex]x^2[/tex] + 3x doesn't have two x-intercepts because ac = 0.

(c) The function k(x) = 8[tex]x^2[/tex] - 5x - 7 have two x-intercepts because ac < 0.

In the theorem, a, b, and c are real numbers.

Theorem - If f is a quadratic function of the form f(x) = a[tex]x^2[/tex] + bx + c and ac < 0, then the function f has two x-intercepts.

(a) The function is g(x) = -8[tex]x^2[/tex] + 5x - 2

On comparing the equation by f(x) = a[tex]x^2[/tex] + bx + c, we get a = -8, b = 5 and c = -2.

To check the two x-intercepts, we put values in ac and compare with ac<0

ac = (-8)(-2)

ac = 16 > 0

As the value of ac is greater than 0. So we can say that it doesn't have two x-intercepts.

(b) The function is h(x) = (-1/3)[tex]x^2[/tex] + 3x

On comparing the equation by f(x) = a[tex]x^2[/tex] + bx + c, we get a = -1/3, b = 3 and c = 0.

To check the two x-intercepts, we put values in ac and compare with ac<0

ac = (-1/3)(0)

ac = 0 = 0

As the value of ac is equal to 0. So we can say that it doesn't have two x-intercepts.

(c) The function is k(x) = 8[tex]x^2[/tex] - 5x - 7

On comparing the equation by f(x) = a[tex]x^2[/tex] + bx + c, we get a = 8, b = -5 and c = -7.

To check the two x-intercepts, we put values in ac and compare with ac<0

ac = 8(-7)

ac = -56

ac < 0

As the value of ac is less than 0. So we can say that it have two x-intercepts.

Step-by-step explanation:

25 cents = $0.25

the ratio is 5/0.25 (5 dates for $0.25)

now we need to convert this to $5 in the denominator. and we need to multiply the numerator with the same factor.

and then the numerator will tell us how many dates we get for $5 in the denominator.

0.25 × x = 5

x = 5/0.25 = 20

indeed, 20 quarters = $5

so, we do

5/0.25 × 20/20 = 100/5

that means we can buy 100 dates for $5.

The words ‘of’ and ‘more than’ are often used in conjunction with percentages. The word ‘of’ is usually used to refer to a portion or part of a whole. For example, ‘50% of the population’ means that half of the population is being referred to.

In comparison, ‘more than’ is used to refer to a number that is higher than the one that is being referred to. For instance, ‘more than 50% of the population’ means that more than half of the population is being referred to.

The two words are related in that they both refer to a number or percentage, but their meanings differ. The word ‘of’ is used to refer to a portion of a number or percentage, while ‘more than’ is used to refer to a number or percentage that is higher than the one being referred to.

Dividing the sum of `(-12)/(5) and (-18)/(15)` by their difference. The answer is 3.

To divide the sum of two numbers by their difference, we first need to find the sum and the difference of the two numbers.

The sum of (-12)/(5) and (-18)/(15) is:

(-12)/(5) + (-18)/(15) = (-12)/(5) + (-6)/(5) = -18/5

The difference of (-12)/(5) and (-18)/(15) is:

(-12)/(5) - (-18)/(15) = (-12)/(5) - (-6)/(5) = -6/5

Finally, dividing the sum by the difference, we get:

(-18/5) / (-6/5) = -18/-6 = 3

Let us consider the event that a college graduate plans on pursuing a graduate degree as a success.

The probability of getting success is p = 0.50

Let X denotes the event of success.

We have, n = 14.

Then,

Yes, w is in col(a) since w can be written as a linear combination of the columns in a. A linear combination of two or more vectors is a vector that can be expressed as a sum of those vectors, with each vector scaled by a scalar (or coefficient). By expressing w as a linear combination of the columns in a, we are saying that w can be expressed as a sum of those columns, with each column scaled by a scalar.

No, w is not in nul(a) since w cannot be written as a linear combination of the columns in a with all scalar coefficients being zero. In other words, w cannot be expressed as a sum of the columns in a such that all coefficients are zero.

Deep Learning (DL) is a type of Artificial Intelligence (AI) that uses a set of algorithms to simulate the functioning of the human brain.

It is a form of machine learning that is based on the concept of neural networks. DL uses a set of algorithms to process large volumes of data and identify patterns in the data. DL can be used to identify patterns and relationships in data that are not easily visible to the human eye.

DL works by using a series of layers of neurons, each of which is connected to the next layer by a set of weights and biases. During the training process, these weights and biases are adjusted so that the output of the neural network is adjusted to match the desired output. This is done by using an optimization algorithm such as gradient descent. At each step, the weights and biases are adjusted until the output of the neural network matches the desired output.

Once the DL model has been trained, it can be used to make predictions from new data. It does this by taking inputs and passing them through the layers of neurons to generate an output. This output is then compared to the desired output and an error is calculated. This error is then used to adjust the weights and biases in order to minimize the error. This process of adjusting the weights and biases is repeated until the error is minimized and the model can make accurate predictions from new data.

The car salesperson made $62,000 in sales for the month

Let us say the amount of sales the car salesperson made in a month is x. Then, the total income can be represented as:

$1,400 + 0.05x = $4,500

The equation represents the total income of the car salesperson as the base salary of $1,400 per month plus a commission of 5% on sales. To find the amount of sales made, we have to solve x.

Subtracting $1,400 from both sides:

0.05x = $4,500 - $1,400 = $3,100

Dividing both sides by 0.05:

x = $3,100 / 0.05 = $62,000
