The function that best describes the graph is y = x² + 9x + 18. The correct option is B. y = x² + 9x + 18
From the question, we are to determine the function that best describes the graph
From the graph, we can observe that the roots of the quadratic equation are x = -6 and x = -3
Thus,
(x + 6) and (x + 3) are factors of the quadratic equation.
Then,
Multiplying the factors, we get
(x + 6)(x + 3) = 0
x(x +3) + 6(x + 3) = 0
x² + 3x + 6x + 18 = 0
x² + 9x + 18 = 0
This means the function is y = x² + 9x + 18

If ATUV is translated to image ATUV, as shown below, by the rule
(x, y) → (x+8, y - 3), what are the coordinates of ATUV?
==========================================================
Explanation:
The given translation rule is (x, y) → (x+8, y - 3) which says "shift 8 units right and 3 units down".
The inverse transformation will undo each to get "8 units left and 3 units up"
So the inverse is (x, y) → (x-8, y + 3)
Use this inverse to determine the preimage of point T'(2,-6)
[tex](\text{x},\text{y})\to(\text{x}-8,\text{y}+3)\\\\(2,-6)\to(2-8,-6+3)\\\\(2,-6)\to(-6,-3)\\\\[/tex]
Therefore, preimage point T is located at (-6,-3) which points us to answer choice B
If we were to apply the rule of "shift 8 units right and 3 units down" to T(-6,-3), you should arrive at T'(2,-6)

The given coordinate pair, (10, -7) is not on the x–axis or the y–axis, but it is in Quadrant IV
What is a coordinate pair?
A coordinate pair specifies a point on the coordinate plane.
The coordinates of points on the x–axis have a y–coordinate of 0
Therefore, the coordinates of a point that is on the x–axis can be expressed as (x, 0)
Points that are on the y–axis have a x–coordinate of 0, which gives the coordinates of the points located on the y–axis as (0, y)
The coordinates of the given point is (10, -7), therefore, the point is neither on the x or y–axis, but in one of the four quadrants.
The coordinate of points in the first quadrant can be represented generally as (x, y)
Points in the second quadrant have the general form of (-x, y)
The points in the third quadrant can be expressed generally in the form (-x, -y)

Solve the given right triangle for its missing angle and side measures.
An Image of a Right triangle FED With E being the right angle and FE being the base with 12units. The acute angle is F at 35degree.
Note: Figure not drawn to scale
A.
m∠D = 35°, DE ≈ 8.40 units, DF ≈ 13.65 units
B.
m∠D = 35°, DE ≈ 8.40 units, DF ≈ 14.65 units
C.
m∠D = 55°, DE ≈ 4.40 units, DF ≈ 13.65 units
D.
m∠D = 55°, DE ≈ 8.40 units, DF ≈ 14.65 units
Answer:
D
Step-by-step explanation:
the sum of the 3 angles in Δ DEF = 180° , that is
∠ D + 90° + 35° = 180°
∠ D + 125° = 180° ( subtract 125° from both sides )
∠ D = 55°
------------------------
using the tangent and cosine ratios in the right triangle
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{DE}{EF}[/tex] = [tex]\frac{DE}{12}[/tex] ( multiply both sides by 12 )
12 × tan35° = DE , then
DE ≈ 8.40 ( to 2 dec. places )
--------------------------
cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DF}[/tex] = [tex]\frac{12}{DF}[/tex] ( multiply both sides by DF )
DF × cos35° = 12 ( divide both sides by cos35° )
DF = [tex]\frac{12}{cos35}[/tex] ≈ 14.65 ( to 2 dec. places )

Choose the number line that correctly compares 24−−√ and 4.256.
The number line that correctly compares √24 and 4.256 is number line C.
What is a number line?A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
This ultimately implies that, a number line can be used for the comparison of two or more numbers such as √24 and 4.256. Also, a number line typically decreases in numerical value towards the left and increases in numerical value towards the right.
Taking the square root of √24, we have:
√24 = 4.899
In this context, we can reasonably and logically deduce that 4.899 is greater than 4.256 (4.899 > 4.256) and would be placed at the right hand side of the number line and further from 4.899 as shown in number line C in the image attached below.

Kevin is making potato casserole for a dinner party. He needs 2½ pounds of potatoes per guest. How many pounds of potatoes will he need for 6 guests?
15 pounds
6.5 pounds
25 pounds
12.5 pounds
2.5lb × 6 guest = 15 pounds
Answer: 15 pounds of potatoes.
Step-by-step explanation:
Kevin will perform basic multiplication to find how many potatoes he needs for all of the guests. Since each person requires 2 1/2 pound of potatoes and there are a total of 6 guests, multiplying these two values will find the pounds of potatoes that are needed for all of the guests.
2 1/2 * 6 = 15 pounds of potatoes
Therefore, Kevin needs 15 pounds of potatoes to make potato casserole for everyone at the dinner party.
Marisol's annual salary as an engineer is $75,000. After receiving a
promotion, her new annual salary is $80,000. What percent increase in her
salary resulted from her promotion?
The percent increase in her salary resulted from her promotion is 6.67%.
The annual salary of Marisol as an engineer = $75000.
After, the promotion salary of Marisol as an engineer = $80000.
We have to find the increment in her salary after promotion in percentage.
Before finding the increment in percentage we find the total increment in dollar in her salary after promotion.
Total increment in dollar = Salary after Promotion − Salary before Promotion
Total increment in dollar = $80,000 − $75,000
Total increment in dollar = $5000
As we know that we can find the percentage by multiplying the required number by 100 because percentage is the ratio with 100.
So, the increment in salary after promotion in percentage.
% increment = (Total increment/Salary before) * 100
% increment [tex]= (\frac{5000}{75000})*100[/tex]
% increment = 0.0667 * 100
% increment = 6.67%
Now we see that percent increase in her salary resulted from her promotion is 6.67%.

Is this a function?
Answer: No, this is not a function.
Functions exist when there are a unique set of x-values and each can match with a y-value. There cannot be a repeating x-value because this creates a discontinuity in the graph. You can have as many repeating y-values as you’d like as long as they each have a unique x-value and are not duplicate plot points.
Since x = 7 repeats in the domain of x-values, this cannot be a function.
