The statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The graph of the function is,
[tex]f(x) = -(x +3)(x - 1)[/tex]
It is positive, its value is above x-axis. For the function above, the solutions are,
[tex]x+3=0\\x=-3\\x-1=0\\x=1[/tex]
The value of x is lies between,
[tex]-3 < x < 1[/tex]
Thus, the statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.

Five roads form two triangles. What is the value of x? Justify your answer.
Using sine rule, the value of x in the triangle formed by five roads is 53.36 degrees.
How to find the angle of triangle using sine law?The value of x can be found using sine rule.
Therefore,
73.2 / sin 37° = 97.6 / sin x
cross multiply
73.2 sin x = 97.6 sin 37°
73.2 sin x = 97.6 × 0.60181502315
73.2 sin x = 58.7371462596
divide both sides by 73.2
sin x = 58.7371462596 / 73.2
x = sin⁻¹ 0.80242003086
x = 53.3618236772
x = 53.36°
Therefore, the value of x is 53.36°

The base of a solid is bounded by x^2 + y^2 = 16. Cross sections perpendicular to the x-axis are right isosceles triangles with one leg located in the base. Which definite integral represents the volume of this solid?
The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.
x² + y² = 16 ⇒ y = ±√(16 - x²)
⇒ length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)
Cross sections with thickness ∆x have a volume of
1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x
since they are isosceles triangles and so their bases and heights are equal.
Then the total volume would be (D)
[tex]\displaystyle \int_{-4}^4 \frac12 \left(2 \sqrt{16-x^2}\right)^2 \, dx[/tex]
Which statement is most likely to be true? the ages of the mackerels are the most dispersed from the team’s mean. the ages of the stars are the most dispersed from the team’s mean. the ages of the dolphins are the most dispersed from the team’s mean. the ages of the giants are the most dispersed from the team’s mean.
The ages of the Stars are the most dispersed from the team’s mean
Which statement is right?Standard deviation is one way to measure the average of the data by determining the spread of the data. It actually explains how much the observation points are further away from the mean of the data.
Higher the standard deviation, higher the spread of the data and higher is the uncertainty. This means that the team with the highest standard deviation will have the most dispersion.
In this case, the standard deviation of 4.1 is the largest number, therefore, the statement "The ages of the Stars are the most dispersed from the team’s mean." is true

You have a budget with room for no more than 30% of your take-home pay
for rent. Your take-home pay is $2,400 per month. How much can you
afford to pay for rent per month? *
Answer:
Rent = 720 dollars / month
Step-by-step explanation:
Remark
You can afford to pay out 30% of your take home pay for rent.
Givens
Take home pay: 2400 dollars.
Rent alotment: 30%
Rent:x
Formula
rent = % of pay * Take home pay
Solution
x = 30/100 * 2400 Divide by 100
x = 0.30 * 2400 Multiply the right
x = 720
For its 28th anniversary, an Uncles Game store is offering a 28% discount on all board games. What is the discounted cost of the game that regularly costs $32. 50?
Answer: $23.40
Step-by-step explanation:
We will find what percent of the normal cost the items are currently.
100% - 28% = 72%
Now, we will find 72% of $32.50
72% -> 0.72
$32. 0 * 0.72 = $23.40
The discounted cost is $23.40.

Answer:
Step-by-step explanation:
So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540
Then it is algebra
540=91+125+92+(3x-5)+(4x-8)
Simplify what you can and collect like terms
540=308+3x-5+4x-8
540=308+7x-13
Then move everything over to the one side so that the variable is isolated
540-308+13=7x
245=7x
242/7=x
35=x

What is the median of the data set?
=========================================================
Explanation:
The diagram shows us we have this data set
{5, 8, 8, 8, 8, 9, 9, 9, 10, 10}
Cross off the outer most items (the 5 and the second 10) to get this smaller set
{8, 8, 8, 8, 9, 9, 9, 10}
Repeat the last step of crossing off the outer most items to get
{8, 8, 8, 9, 9, 9}
Keep this process going until we have this set of steps
{8, 8, 9, 9}
{8, 9}
We have two items left, which are tied for the middle, so we compute the midpoint
(8+9)/2 = 17/2 = 8.5 is the median
This is the middle most value
