which of the following best describes the quadratic function below ?
A. a parent function
B. an inverse function
C. opens right
D. opens down
Option A is correct, a parent function best describes the quadratic function.
The quadratic function with a vertex at the origin and opening upward is best described as a parent function.
A parent function is the most basic form of a particular type of function.
In the case of quadratic functions, the parent function is f(x) = x².
It has a vertex at the origin (0, 0) and opens upward.
Therefore, a parent function best describes the quadratic function.

Step-by-step explanation:
1e. Combine like terms.
(3t² +3t -6) +(-t² +5t) = t²(3 -1) +t(3 +5) -6
= 2t² +8t -6

2h. (2a² +3ab -4b²) -(a² +ab -b²)
Use the distributive property to eliminate parentheses. Note that all signs change in the second set of parentheses.
= 2a² +3ab -4b² -a² -ab +b² = a²(2 -1) +ab(3 -1) +b²(-4+1)

Answer:
11. 35 ft²
12. 24 cm²
13. 18 ft²
14. 28 in²
15. 9 in²
Step-by-step explanation:
11. A= (b×h)÷2
= (10×7)÷2
= 70 ÷ 2
= 35 ft²
12. A= (b×h)÷2
= (8×6)÷2
= 48 ÷ 2
= 24 cm²
13. A=(b×h)÷2
=(9×4)÷2
= 36 ÷ 2
= 18 ft²
14. A=(b×h)÷2
=(7×8)÷2
= 56 ÷ 2
= 28 in²
15. A=(b×h)÷2
=(3×6)÷2
= 18 ÷ 2
= 9 in²

Tyler needs to complete this table for his consumer science class. He knows that 1 tablespoon contains 3 teaspoons and that 1 cup contains 16 tablespoons.
What are the values of t, x, y, and c ?
Answer:
Step-by-step explanation:
This table reflects the proportional relationship amongst number of teaspoons, number of tablespoon, number of cups.
In other words these three measures are proportional.
By taking proportionality ratio of 'number of tablespoons' and 'number of cups' first.
[tex]\frac{12}{48}=\frac{C}{3}[/tex]
C = [tex]\frac{12\times 3}{48}[/tex]
C = 0.75
Similarly, [tex]\frac{y}{2}=\frac{12}{C}[/tex]
[tex]\frac{y}{12}=\frac{2}{0.75}[/tex]
y = [tex]\frac{24}{0.75}[/tex]
y = 32
Now, [tex]\frac{t}{36}=\frac{y}{12}[/tex]
[tex]\frac{t}{36}=\frac{32}{12}[/tex]
t = 96
By the same rule,
[tex]\frac{36}{x}= \frac{12}{48}[/tex]
x = [tex]\frac{48\times 36}{12}[/tex]
x = 144
Therefore, complete table will be,
Number of teaspoons Number of tablespoons Number of cups
96 32 2
36 12 0.75
144 48 3

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
The four options
Now,
This is because the electric field at a point in space is in the direction of the force that the electric field would exert on a positive test charge if there were a positive test charge at that point in space1. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.
Therefore, by unitary method the answer will be Lines with arrows that point outward radiate from the charge in all directions.

Solve for x. 6/x+ 2/5 = 8
Answer:
15/19
Step-by-step explanation:
6/x +2/5 = 8
(multiply through by x)
6 + 2x/5 = 8x
(minus 8x from both sides)
-38x/5 + 6 = 0
(subtract 6 from both sides)
-38x/5 = -6
(times by -1)
38x/5 = 6
Times 6 by 5 and then divide by 38.

Mona needs to photocopy a 14.5 centimeters wide by 15 centimeters long picture. She wants to enlarge the picture so that its length will be
37.5 centimeters. How wide will the enlarged picture be?
O a
38.8 cm
Ob
37 cm
ос
93.75 cm
Od
36.25 cm
Answer:
The enlarged picture will have a width of 35.8 cm
Step-by-step explanation:
We can solve this question by proportions, using rule of three.
When the length is of 15 centimeters, the width will be of 14.5 centimeters. What is the width when the length is 37 centimeters?
15 cm - 14.5 cm
37 cm - x
Applying cross multiplication
[tex]15x = 14.5*37[/tex]
[tex]x = \frac{14.5*37}{15}[/tex]
[tex]x = 35.8[/tex]
The enlarged picture will have a width of 35.8 cm
Answer:
36.25 cm
Step-by-step explanation:
37.5 divided by 15 is 2.5 then multiply 14.5 by 2.5 and your answer will be 36.25 cm.

Given a point translated from A(1,2) to B(4,4). If a point C at (0,0) is translated in the same way, what will be its new endpoints?
A.(−3,−2)
B.(3,2)
C.(2,2)
D.(3,3)
please help
Answer:
B. (3,2)
Step-by-step explanation:
Step 1) When shifting from A(1,2) to B(4,4), the point shifted 3 units to the right (which means x=3) and 2 units upwards (which means y=2).
Step 2) So when you apply the same movements to point C(0,0), the new point will be (3,2).
See the diagram below. Step 1 is the graph on the left. Step 2 is the graph on the right. The movement is colored in green. Hope this helps!
