The answer is:
The function is greater or equal to 0 at the points (-3,6), (-2,0), (0,6) and (4,0).
Why?To find where the function is greater or equal to 0, we need to look (using the graph) where the function is above the x-axis
So, we can see that the function is above the x-axis from the point (-3,6) to the point (4,0), for these points, the function is greater or equal to 0.
Hence, the function is greater or equal to 0 at the points (-3,6), (-2,0), (0,6) and (4,0), or the function is greater or equal to 0, from -3 to 4 (x-axis values or input).
We have that:
[tex]f(-3)=6\\6\geq 0\\\\f(-2)=0\\0=0\\\\f(0)=6\\6\geq 0\\\\f(4)=0\\0=0[/tex]

A rectangular patio has an area of 91 fl. The length is 6 feet
longer than the width. Find the dimensions of the patio area
Solve by completing the square, Find the width and the length interms of w. Write an equation for the total area Find b/2 Find the dimensions.
Answers
Answer:
Total area equation = tex]w(w+6)=91[/tex]
b/2 = 3
Dimensions of the patio: width = 7 feet, length = 13 feet
Step-by-step explanation:
The area of a rectangle is given the formula:
[tex]A=wl[/tex]
where
[tex]w[/tex] is the width
[tex]l[/tex] is the length
We know from our problem that the area of the patio is 91 square feet, so [tex]A=91[/tex]. We also know that the length is 6 feet longer then the width, so [tex]l=w+6[/tex].
Replacing values in our area equation
[tex]A=wl[/tex]
[tex]91=w(w+6)[/tex]
[tex]w(w+6)=91[/tex]
Expanding the left side:
[tex]w*w+6w=91[/tex]
[tex]w^2+6w=91[/tex]
Remember that to complete the square we need to add half the coefficient of the linear term squared. The lineal term is [tex]w[/tex], so its coefficient is 6. Now, half its coefficient or [tex]\frac{b}{2} =\frac{6}{2} =3[/tex]. Finally, [tex]3^2=9[/tex].
To complete the square we need to add 9 to both sides of the equation:
[tex]w^2+6w+9=91+9[/tex]
[tex]w^2+6w+9=100[/tex]
Notice that the left side is a perfect square trinomial (both [tex]w^2[/tex] and 9 are perfect squares), so we can express it as:
[tex](w+3)^2=100[/tex]
Now that we completed the square, we can solve our equation
- Take square root to both sides
[tex]\sqrt{(w+3)^2} =\pm\sqrt{100}[/tex]
[tex]w+3=\pm10[/tex]
- Subtract 3 from both results
[tex]w=10-3,w=-10-3[/tex]
[tex]w=7,w=13[/tex]
Since length cannot be negative, [tex]w=7[/tex] is the solution of our equation.
We now know that the width of our rectangular patio is 7 feet, so we can find its length:
[tex]l=w+6[/tex]
[tex]l=7+6[/tex]
[tex]l=13[/tex]
We can conclude that half the coefficient of the width is [tex]\frac{b}{2}=3[/tex], the width of the patio is 7 feet, and its length is 13 feet.

Which statement is true???
Answers
Answer:
Option A.
Step-by-step explanation:
Let A represents have soup and B represents having salad for lunch.
If two events are not dependent on each other, then they are known as independent events.
Probability of having soup is not dependent on Probability of having salad.
[tex]P(A\cap B)=P(A)P(B)[/tex]
Using the formula of conditional probability, we get
[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}\Rightarrow \frac{P(A)P(B)}{P(B)}=P(A)[/tex]
[tex]P(B|A)=\frac{P(A\cap B)}{P(A)}\Rightarrow \frac{P(A)P(B)}{P(A)}=P(B)[/tex]
Having soup or salad for the lunch are two independent event because [tex]P(A|B)=P(A)[/tex] and [tex]P(B|A)=P(B)[/tex].
Therefore, the correct option is A.
The correct answer is:
c) Having soup and salad are not independent events because P(A|B) ≠ P(A) and P(B|A) ≠ P(B).
Given that two events A and B, A represent having soup and B represent having salad for lunch.
We need to determine if the events are independent.
To determine if having soup (A) and salad (B) for lunch are independent events, we need to compare the conditional probabilities with the individual probabilities.
The events A and B are independent if and only if:
P(A|B) = P(A) and P(B|A) = P(B)
where P(A|B) is the probability of having soup given that salad is already chosen, P(A) is the probability of having soup in general, P(B|A) is the probability of having salad given that soup is already chosen, and P(B) is the probability of having salad in general.
Now, let's evaluate each statement:
a) Having soup and salad for lunch are independent events because P(A|B) = P(A) and P(B|A) = P(B).
This statement suggests that both conditional probabilities are equal to the individual probabilities, which would mean the events are independent. However, this contradicts the definition of independent events, where both conditional probabilities should be equal for independence.
b) Having soup and salad for lunch are not independent events because P(A|B) = P(A) and P(B|A) = P(B).
This statement is also incorrect because it states that the conditional probabilities are equal to the individual probabilities, which would indicate independence, but that is not the case.
c) Having soup and salad are not independent events because P(A|B) ≠ P(A) and P(B|A) ≠ P(B).
This statement correctly states that both conditional probabilities are not equal to the individual probabilities, indicating that the events are not independent. This is the correct answer.
d) Having soup and salad for lunch are independent events because P(A|B) ≠ P(A) and P(B|A) ≠ P(B).
This statement is incorrect because it suggests that the events are independent based on the fact that the conditional probabilities are not equal to the individual probabilities. However, this reasoning is flawed, and the correct interpretation for independence is when the conditional probabilities are equal to the individual probabilities.
Therefore, the correct answer is:
c) Having soup and salad are not independent events because P(A|B) ≠ P(A) and P(B|A) ≠ P(B).

At what age do babies learn to crawl? Does it take longer to learn in the winter when babies are bundled in clothes to restrict their movement? Data was collected from parents who brought their babies to New York University Infant Study Center to participate in one of a number of experiments between 1988 and 1991. Parents reported ages (in weeks) at which their child was first able to crawl a distance of four feet within one minute. The researchers also recorded the average outdoor temperature (in F) 6 months after the babies; date of birth. The resulting data were grouped by month of birth and all data for babies born on a given month averaged together. If you fit the least-squares line to the 12 data points (one for each month) you obtain the following results from a software package. Notice that the temperature given is taken as the explanatory variable and crawling age as the response variable. The dependent variable is the average crawling age.

The correct range for the coefficient of temperature on the crawling age of babies is (0.055, 0.105), indicating a positive impact of temperature on the age at which babies learn to crawl.
A: (0.053, 0.103) The line equation obtained from the least-squares method for the data points indicates that temperature has a positive effect on the age at which babies learn to crawl. The coefficient value of -0.077739 for the temperature variable implies that on average, for every one-degree Fahrenheit increase in temperature, the crawling age increases by 0.077739 weeks. Therefore, the correct range is option B: (0.055, 0.105).

3. Find the radius of a circle with a circumference
of 106.81 centimeters.
Answers
Answer:
r = 16.9 cm
Step-by-step explanation:
We are given the circumference of a circle to be 106.81 cm and with the help of this, we are to find the radius of the circle.
We know that the formula for the circumference is given by:
[tex] 2\pi r [/tex]
so equating the given value to get:
[tex] 2 \pi r = 106.81 [/tex]
[tex] r = \frac { 106.81 } { 2\times \pi } [/tex]
r = 16.9 cm
For this case we have that by definition, the circumference of a circle is given by:
[tex]C = \pi * d[/tex]
Where:
d: It is the diameter of the circle.
[tex]d=2r[/tex]
Clearing we have:
[tex]C=2\pi*r\\r=\frac{C}{2\pi}\\r=\frac{106.81}{2\pi}\\r=17,0079[/tex]
Rounding the amount and [tex]\pi=3.14[/tex]

Write an equation in standard form of an ellipse that has a vertex at (0,6), and a co-vertex at (1,0), and an center at the origin
Answers
Answer:
The standard form of the equation of the ellipse is x² + y²/36 = 1
Step-by-step explanation:
* Lets revise the standard equation of the ellipse
- The standard form of the equation of an ellipse with
center (0 , 0) is x²/b² + y²/a² = 1
, where
* the length of the major axis is 2a
* the coordinates of the vertices are (0 , ±a)
* the length of the minor axis is 2b
* the coordinates of the co-vertices are (±b , 0)
* the coordinates of the foci are (0 , ± c), where c² = a² - b²
* Now lets solve the problem
∵ The vertex of the ellipse is (0 , 6)
∴ a = 6
∵ The co-vertex is (1 , 0)
∴ b = 1
∵ the center is the origin (0 , 0)
∵ The standard form equation is x²/b² + y²/a² = 1
∴ x²/(1)² + y²/(6)² = 1 ⇒ simplify
∴ x² + y²/36 = 1
* The standard form of the equation of the ellipse is x² + y²/36 = 1

Step-by-step explanation:
To solve for the unknown number given the rectangle's dimensions and perimeter, we set up an equation in terms of the unknown number, which represents the width, and solve for it, finding that the number is approximately 8.33.
The question involves finding a specific number given the perimeter of a rectangle and the relationships between its dimensions. First, let's represent the unknown number as x. Given, the length (L) is 2 cm more than x, so L = x + 2. The width (W) is twice x, so W = 2x. The perimeter (P) of a rectangle is given by 2(L + W), and we're told it is 54 cm.
Substituting the expressions for L and W into the perimeter formula gives: 2((x + 2) + 2x) = 54. Simplifying, we get 6x + 4 = 54, and further simplifying results in 6x = 50. Dividing both sides by 6 gives x = 8.33. Therefore, the unknown number is approximately 8.33.

Answers
Answer:
3.5
Step-by-step explanation:
First we use the concept of relative speed.
The rates of the 2 planes are 625 mph & 575 mph.
Relative speed will be:
(speed of plane A)+(speed of plane B)
=625+575
=1,200 mph
Distance=4200 miles
Thus the time taken for them to meet will be:
Time=distance/speed
=4200/1200
=3.5 hours
We therefore conclude that the planes met after 3.5 hours.

7x = 63 ( divide both sides by 7 )
x = 9
ANSWER
x=9
y=5
EXPLANATION
The y triangle is an equilateral triangle.
Each measure of an equilateral triangle is 60°
This implies that:
(7x-3)°=60°
Add 3 to both sides
7x=60+3
7x =63
Divide both sides by 7
[tex]x = \frac{63}{7} [/tex]
[tex]x = 9[/tex]
Also,
11y+5=60°
Subtract 5: from both sides of the equation
11y=60-5
11y=55
Divide both sides by 11

Answer:
14x-6y=4 and 14x-28y=1
Step-by-step explanation:
we have
7x-3y=4 ----> equation A
2x-4y=1 ----> equation B
Multiply the equation A by 2 both sides
2*(7x-3y)=4*2
14x-6y=8
Multiply the equation B by 7 both sides
7*(2x-4y)=1*7
14x-28y=7
therefore
The system of equations that is not equal to the system of equations above is
14x-6y=4 and 14x-28y=1
