Describe the solution set of each of the following quadratic inequality or not
Answer:
See below
All the inequalities can be solved by making a table, but once they are simple factored quadratic expressions, we already know what interval it will have.
Step-by-step explanation:
1)
[tex]x^2+9x+14>0[/tex]
Factoring the expression, we have
[tex](x+2)(x+7)>0[/tex]
Considering that
[tex](x+2)(x+7)=0[/tex]
for [tex]x = -2[/tex] and [tex]x=-7[/tex] you can see that for
[tex](x+2)(x+7)>0[/tex]
[tex]x \not\in (-7, -2)[/tex]
Therefore,
[tex]S = \{x\in\mathbb{R} : x<-7 \text{ or } x>-2 \}[/tex]
[tex]S = (-\infty,-7)\cup (-2,\infty)[/tex]
2)
[tex]x^2-10x+16<0[/tex]
You can factor it again.
[tex](x-2)(x-8)<0[/tex]
You can make the table to solve all the inequalities, but once we have the expression [tex]< 0[/tex], we know that
[tex]2<x<8[/tex], therefore,
[tex]S = (2, 8)[/tex]
3)
[tex]2x^2+11x+12<0[/tex]
Factoring we have
[tex](2x+3)(x+4)<0[/tex]
Find the solutions for
[tex](2x+3)(x+4)=0[/tex]
And we know that
[tex]-4<x<-\dfrac{3}{2}[/tex]
[tex]S = \left(-4,-\dfrac{3}{2}\right)[/tex]

Which shows a box-and-whisker plot for the following data?
57, 38, 27, 40, 48, 43, 37, 33, 33, 34, 38, 44, 37, 35, 52
HELP PLS
Answer:
D
Step-by-step explanation:
Find the min, Q1, median, Q3, and Max of the data given.
✔️Arrange the data in an ordered manner:
27, 33, 33, 34, 35, 37, 37, 38, 38, 40, 43, 44, 48, 52, 57
✔️Min = 27
✔️Q1 = the 4th data set = 34
✔️Median = the 8th data set = 38
✔️Q3 = 12th data set = 44
✔️Max = 57
Therefore, the box plot that has all these values represented corrected is the box plot in the last option (D).

The perimeter of a polygon is 96 ft.
Write and solve an equation to find “m”.
Answer:
m = 12
Step-by-step explanation:
Total perimeter = 3m + 3m + m + m = 96
so, 8m = 96
then m = 12
A beverage company surveyed 450 adults to determine the demand for summer drinks.
How many people preferred drinking water?
WHO EVER ANSWERS GETS MARK AS BRAINLIEST
Answer:
174 people preferred drinking water.
Step-by-step explanation:
Given that:
A total of 450 males and females were surveyed.
203 were males.
Number of females = 450 - 203 = 247 females
247 females were surveyed.
Now, we will find the number of females who prefer water.
Let,
x be that number.
Total number of females = Soda + Iced tea + Lemonade + Water
247 = 28 + 44 + 67 + x
247 = 139 + x
247-139 = x
x = 108
Number of people who prefer water = 108 + 66 = 174
Hence,
174 people preferred drinking water.

Write the equation of the parabola in vertex form.
vertex (3,1), point (2, - 6)
f(x) =?
Answer:
[tex]f(x)=-7(x-3)^2+1[/tex]
Step-by-step explanation:
Vertex form of a quadratic is given by:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h, k) is the vertex and a is the leading coefficient.
We are given that the vertex is (3, 1). Hence, h = 3 and k = 1. By substitution:
[tex]f(x)=a(x-3)^2+1[/tex]
We are also given a point (2, -6). This means that when x = 2, f(x) = -6. Hence:
[tex]-6=a((2)-3)^2+1[/tex]
Solve for a. Subtract:
[tex]-6=a(-1)^2+1[/tex]
Simplify:
[tex]-6=a+1[/tex]
Therefore:
[tex]a=-7[/tex]
Hence, our quadratic is:
[tex]f(x) = -7 (x-3)^2 + 1[/tex]

Mr. Foster paid $160 to rent a car for 5 days. If the cost for each day was the same, how much did he pay each day that he rented the car?
Answer is 32
Step-by-step explanation:
Answer:
32
Step-by-step explanation:
160/5 = 32 because if your paying 160 dollars every week you for 1 month which is v weeks you're paying 640 a month for renting a car so if you divide 640/20 you get 32 and 160 /5 is 32

Pls Help..... 50 points and brainliest if you answer correctly!
Answer:
5
Step-by-step explanation:
The left side is equal to:
x/(2.52-2.02) = x/0.5 = 2x
Let's simplify the numerator of the right side.
9*(31/20 - 1.05) = 9*(0.5) = 9/2
The denominator is 43/40 - 35/8 /7 = 43/40 - 5/8 = 43/40 - 25/40 = 18/40 = 9/20.
So 2x = (9/2)/(9/20) = 10
x = 5

Which statement comparing the shapes of the dot plots is true?
Both the Highlands and the Lowlands data points are evenly distributed around the center.
Both the Highlands and the Lowlands data points are clustered toward the left of the plot.
The Highlands data points are evenly distributed around the center, while the Lowlands data points are clustered toward the left of the plot.
The Highlands data points are clustered toward the left of the plot, while the Lowlands data points are evenly distributed.
Answer C
On the graph, it shows how the Highlands has more dots to the middle so it is clustered there in that are.
If you look at the Lowlands, you can see that the dots are more on the left.

What is the measure of B?
Answer: ∠B = 82°
Step-by-step explanation:
To find the measure of B, you have to find the measure of A.
m∠143° + m∠A = 180° because they are a linear pair
m∠A + 143 = 180
Subtract both sides by 143
m∠A = 37
Since you know the measure of angle A, you can find angle B
Angle A, B, and C should add up to 180° as triangles' angles sum up to 180°.
∠B + ∠A + ∠C = 180°
Substitute
∠B + 37 + 61 = 180
∠B + 98 = 180
Subtract 98 from both sides
∠B = 82°

Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
To find the scale factor of a dilation, we first find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the purple shape. The top edge of the black shape measures 15 units while the top edge of the purple shape measures 3 units
Now, we divide the length taken from the figure by the length taken from the original shape. In this case, we divide the length of 3 by the length of 15.

The asymptote of the function f(x) = 3x + 4 is y =
Answer:
Conclusion:
No vertical asymptotes. No horizontal asymptotes. No slant asymptotes.Step-by-step explanation:
Given the function
f(x) = 3x + 4
Determining the VERTICAL ASYMPTOTES
The line x = L is a vertical asymptote of the function y=3x+4 if the limit of the function (one-sided) at this point is infinite.
It means that possible points are points where the denominator equals 0 or doesn't exist.
So, find the points where the denominator equals 0 and check them.
As can be seen, there are no such points, so this function doesn't have vertical asymptotes.
Determining the HORIZONTAL ASYMPTOTES
Line y = L is a horizontal asymptote of the function y=f(x) if either [tex]\lim _{x\to \infty }\:f\left(x\right)=L[/tex] or [tex]\lim _{x\to -\infty }\:f\left(x\right)=L[/tex], and L is finite.
Calculate the limits:
[tex]\:\lim \:_{x\to \:\infty \:}\:\left(3x+4\right)=\:\infty \:[/tex]
[tex]\:\lim \:_{x\to \:-\infty \:}\:\left(3x+4\right)=\:-\infty \:[/tex]
Thus, there are no horizontal asymptotes
Determining the SLANT ASYMPTOTES
Since the degree of the numerator is not one degree greater than the denominator, then there are no slant asymptotes.
Conclusion:
No vertical asymptotes. No horizontal asymptotes. No slant asymptotes.Answer:
For plato family
