What is the range of y=−3x2−12x−17?

Question 9 options:

y≤−5

y≥5

x≥−5

x≤5

The best way to do this is to use the butterfly method. Assume the ? = x

[tex]\frac{1}{10} = \frac{x}{1,000} \\10x = 1,000\\x = 100[/tex]

Thus, the question mark would be 100

Step-by-step explanation:

it makes the most sense

option D is correct.

Explanation:

[tex]\rightarrow \sf f(x) = 2x-9[/tex]

To find inverse, make x the subject

[tex]\rightarrow \sf f(x)+9 = 2x[/tex]

[tex]\rightarrow \sf x = \dfrac{ f(x)+9}{2}[/tex]

So the inverse is:

[tex]\rightarrow \sf g(x) = \dfrac{ x+9}{2}[/tex]

Rest all options are incorrect and is not inverse of each other.

15/20 in simplest form is 3/4

Step-by-step explanation:

15/20 in simplest form is 3/4 cause if you divide 15 by 5 you get 3 and if you divide 20 by 5 you get 4

The simplest form of the given fraction 15/20 is 3/4.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, Kenisha's dog ate 15/20 of a bag of dog food last week.

The simplest form is the smallest possible equivalent fraction of the number.

Here, simplest form of 15/20

Divide both the numerator and denominator by 5, we get

15÷5/20÷5 = 3/4

Therefore, the simplest form of the fraction is 3/4.

Area of a rectangle = width × length

Substituting the given values:

⇒ Area of the garden = w(w + 6)

                                    = w² + 6w

A  linear function that represents the profit generated from selling the manufactured kayaks is P(x) = $575x - $480x.

Profit is the total selling price of an item less the cost price.

Profit = selling price - cost price.

A linear function is a function that has a single variable raised to the power of 1. An example is x + 2 The variable x is raised to the power of 1. 2 is the constant terms.

P(x) = $575x - $480x.

Where x represents the number of manufactured kayaks sold

The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.

Speed can be calculated as the ratio of distance traveled to the time taken.

The speed that a tsunami can travel is modeled by the equation

s = 356√d, where s is the speed in kilometers per hour and d is the average depth of the water in kilometers.

S = 356√d

200 = 356√d

√d = 200/356

= 0.5618

d = 0.5618^2

= 0.316 km

d = 0.32 km.

Thus, The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.

Each term is a number or a number multiplied by a one or more variables.

The center of the circle x² + y² + 8x − 6y + 21 = 0 is at (-4, 3) and the radius of the circle is 2 units.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The equation of the circle is given as

x² + y² + 8x − 6y + 21 = 0

The equation can be written as

x² + 8x + 16 + y² − 6y 9 = 4

(x + 4)² + (y − 3)² = 2²

Then the center of the circle is at (-4, 3) and the radius of the circle is 2 units.

Given

#1) Subtract 15 from each side.

#2) Divide 2 from each side.

The probability that a person has a positive rh factor given that he/she has type O blood is approximately 82.2 %

For two events A and B:

The chain rule states that the probability that A and B both occur is given by:

[tex]P(A \cap B) = P(A)P(B|A) = P(B)P( A|B)[/tex]

Suppose two dimensions are there, viz X and Y. Some values of X are there as [tex]X_1, X_2, ... , X_n[/tex] and some values of Y are there as [tex]Y_1, Y_2, ... , Y_n[/tex]

List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:

Value(ith row, jth column) = Frequency for intersection of  [tex]X_i[/tex] and [tex]Y_j[/tex] (assuming X values are going in rows, and Y values are listed in columns).

Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.

For n = 2, and k = 2, the table would look like:

[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]

where S denotes total of totals, also called total frequency.

n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.

The missing two-way table for this problem is given below:

[tex]\begin{array}{cccccc}&A&B&AB&O&\rm Total\\\text{Negative}&0.07&0.02&0.01&0.08&0.18\\\text{Positive}{&0.33&0.09&0.03&0.37&0.82\\\rm Total & 0.40&0.11&0.04&0.45&1 \end{array}[/tex]

Instead of frequencies, it contains ratio of frequency to total count of people surveyed (thus, relative frequency).

We want the probability that a person has a positive rh factor given that he/she has type O blood.

If we take:

E = event that a random person chosen has a positive rh factor

and F = event that a random person chosen has type O blood

Then, the needed probability is written symbolically as:

P(E|F).

Using the considered two-way table and the chain rule, we get this probability as:

[tex]P(E|F) = \dfrac{P(E \cap F)}{P(F)} = \dfrac{n(E \cap F)/ n(Total)}{n(F)/n(Total)}[/tex]

Since the two way table consists relative frequency with total count, so, we get:

[tex]n(E \cap F)/n(Total) = 0.37\\n(F)/n(Total) = 0.45[/tex]

[tex]P(E|F) = \dfrac{n(E \cap F)/ n(Total)}{n(F)/n(Total)} = \dfrac{0.37}{0.45} \approx 0.822 = 82.2\%[/tex]

Thus, the probability that a person has a positive rh factor given that he/she has type O blood is approximately 82.2 %
