The graph of the function f(x) = (x + 2)(x + 6) is shown below.
On a coordinate plane, a parabola opens up. It goes through (negative 6, 0), has a vertex at (negative 4, negative 4), and goes through (negative 2, 0).
Which statement about the function is true?
The function is positive for all real values of x where
x > –4.
The function is negative for all real values of x where
–6 < x < –2.
The function is positive for all real values of x where
x < –6 or x > –3.
The function is negative for all real values of x where
x < –2.
The correct statement regarding the graph of the function f(x) = (x + 2)(x + 6) is given by:
The function is negative for all real values of x where -6 < x < -2.
What is the missing information?The graph of the function f(x) = (x + 2)(x + 6) is missing, and is given at the end of the answer.
When a function is positive and when it is negative?We have to look at the graph of the function relative to the x-axis, as follows:
A function is positive when it is above the x-axis.A function is negative when it is below the x-axis.Hence, for function f(x) = (x + 2)(x + 6), we have that:
It is positive for x < -6 and x > -2.It is negative for -6 < x < -2.Hence the correct statement for the signal of the function is given as follows:
The function is negative for all real values of x where -6 < x < -2.

a company sold yogurt in 120 g pots and one-eight of the content of the pots was chopped fruit, it is then decided to make the pots of yogurt 2/3 of their original weight with 1/5 fruit. will the company use more or less fruit per new design?
Answer:
More fruit for the new design.
Step-by-step explanation:
120 times 2/3 is 80.
1/5 of 80 is 16.
1/8 of 120 is 15.
15 < 16, so the second design has more fruit.

RSTU ≅ R'S'T'U' and R'S'T'U' is also a parallelogram with two pairs of parallel sides.
Given that, parallelogram RSTU is rotated 180° clockwise about the origin.
We need to find how many pairs of parallel sides the rotated figure has.
What is the rotation of 180°?Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in an anticlockwise or clockwise direction, it takes the new position M' (-h, -k).
The given transformation was performed on parallelogram RSTU = 180° clockwise rotation.
Given that a rotation is a form of rigid transformation, the shape and size of the preimage RSTU will be equal to the shape and size of the image R'S'T'U'.

How many quarts of pure antifreeze must be added to 3 quarts of a 10% antifreeze solution to obtain a 30% antifreeze solution?
_quart(s) of pure antifreeze must be added.
There are 0.857 quarts of pure antifreeze that must be added to 3 quarts of a 10% antifreeze solution to obtain a 30% antifreeze solution.
What is the percentage?
The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that there is 10% times 3 quarts or 0.3 quarts of antifreeze in the current mix and we want a 30% solution.
Let the amount of pure antifreeze to be added would be x
The equation to solve becomes,
⇒ (0.3 + x )/(3 + x) = 0.3
⇒ (0.3 + x ) = 0.3 × (3 + x)
⇒ (0.3 + x ) = 0.9 +0.3x
⇒ 0.7x = 0.6
⇒ x = 0.857
Therefore, we need to add 0.857 quarts of pure antifreeze to the current solution to make a 30% solution.

10. You're conducting a vertical jump test on your athletes. This individual just broke the school record
(woohoo!) and achieved a height of 40 inches (1.016m). Calculate their 1) initial velocity and 2) flight time.
1.016m
The jump of the athlete to 40 inches, (1.016 m) is obtained using an initial velocity and time calculated as follows;
1) The initial velocity of the athlete is approximately 4.475 m/s
2) The time of flight which is the time to reach 40 inches and back is approximately 0.91 seconds
Which equation can be used to calculate the velocity and time of the motion?The height achieved by the athlete, h = 40 inches
40 inches = 1.016 mRequired;
1) The initial velocity
Solution;
From the kinematic equation of motion, for a free fall, we have;
v² = u² - 2•g•hWhere;
v = The velocity at the final point = 0 (The athlete stops upward motion at the 1.016 m height and starts downward motion
u = The initial velocity
g = Acceleration due to gravity ≈ 9.81 m/s²
h = The height = 1.016 m
Which gives;
0² = u² - 2 × 9.81 × 1.016
u² = 2 × 9.81 × 1.016 ≈ 19.93392
u = √(19.93392) ≈ 4.465
The initial velocity of the athlete, u, is approximately 4.465 m/s2) The flight time;
The flight time can be found using the equation;
v = u - g•tWhich gives;
t = (u - v)/g
Where;
t = The time taken to reach maximum height.
Therefore;
t ≈ (4.465 - 0)/9.81 ≈ 0.455
The time taken to reach the record height is the same as the time to land back on the ground, which gives;
Time of flight = t + t = 2•t
The time of flight ≈ 2 × 0.445 ≈ 0.910
The time of flight is approximately 0.91 seconds.

Use the GCF and the Distributive Property to find the sum of 38 + 57
Answer:
95
Step-by-step explanation:
You want the sum of 38 and 57 by making use of the GCF and the distributive property.
GCFThe GCF of two numbers can be found by looking at their difference (or their remainder when one divides the other). Here, that is ...
57 -38 = 19
This value is a factor of both numbers, so is their GCF.
Distributive propertyThe distributive property tells us how to express the sum with the GCF factored out:
38 +57 = 19(2 +3)
Then the sum is ...
19(2 +3) = 19(5) = 95
The sum is 95.

Answer:
Step-by-step explanation:
Based on the calculations, the IQR of this data is equal to 2.
How to determine the IQR of this data?
IQR is an acronym for interquartile range and it is a measure of the middle 50% of data values when they are ordered from lowest to highest.
Next, we would order the data from lowest to highest and then determine the median as follows:
Data = {1, 4, 4,} 4, {4, 6, 5}
Median = 4.
For Q₁ of the lower half of the data, we have:
Lower half = {1, 4, 4,}
Q₁ = 4.
For Q₃ of the upper half of the data, we have:
Upper half = {4, 6, 5}
Q₃ = 6.
Mathematically, IQR is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):
IQR = Q₃ - Q₁
IQR = 6 - 4
IQR = 2.
