Answer: D) All real numbers greater than or equal to -4.
Explanation:
The lowest point occurs when y = -4, which is where the vertex is located.
The range consists of y values such that y = -4 or y > -4. We can shorten that last sentence to say [tex]y \ge -4[/tex]. So y is greater than or equal to -4.
As you can probably tell, the range is the set of all possible outputs of a function.

Simplifying
3n + 7 + -2 = 0
Reorder the terms:
7 + -2 + 3n = 0
Combine like terms: 7 + -2 = 5
5 + 3n = 0
Solving
5 + 3n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + 3n = 0 + -5
Combine like terms: 5 + -5 = 0
0 + 3n = 0 + -5
3n = 0 + -5
Combine like terms: 0 + -5 = -5
3n = -5
Divide each side by '3'.
n = -1.666666667
Simplifying
n = -1.666666667

Answer:
Hi!
Step-by-step explanation:
I think you will be okay! I calculated your average by adding all of them and dividing by the number of classes you are taking and it is still around a 96.5!! That is really good! If you are an overachiever like me, I understand that maybe you think it isn't your full potential, but trust me, it is a really good grade!! Whatever high school you are applying to (I'm not too sure how it works because I just went to my public highschool lol) will see you are taking a lot of classes and are doing phenomenal in all of them! I would try asking for extra credit or finding out if there is any way you can raise your grade, I do that when I am not happy with my grades. If you wanted to figure our your GPA out of 4.0 I think there are gpa calculators if you look them up. I hope this was helpful!
An ant crawls 14 cm down into an ant hole. It then crawls 6 cm up to the queens nest. What is the current location of the ant?
Answers
Answer:
8cm
Step-by-step explanation:
We subtract 14 from the location of the ant as it traverses down the hole
0 - 14
= -14
As the ant crawls up we at 6
-14 + 6
= -8
The answer would be 8 cm under elevation
If the base of a triangle is 20mm and the area of the triangle is 40m2. then what will be the height and how can we find it
Answers
Use the formula for area of a triangle:
Area = 1/2 x base x height.
Fill in what you know:
40 = 1/2 x 20 x height
Multiply both sides by 2:
80 = 20 x height
Divide both sides by 20
Height = 4 m
Answer: 4 mm
Step-by-step explanation: this is because if you double the area then you will get the Area of 80 and if you divide it by 20 you will get 4 mm

A driver is driving at a constant speed and drives 9 miles. It takes her 10 minutes to drive this far. What is her speed in miles per hour? Help me please, thank you.
Answers
Answer:
1. This means that the actual park size is 50 times larger than the size of the park on the map.
2. If a pathway is 7 inches long on the map, it will be 50 times larger in real life;
= 7 * 50
= 350 inches
3. 1 foot is 12 inches so 350 inches will be;
= 350/12
= 29.2 feet
4. The real life length of the car is;
= 5 * 67
= 335 inches
5. The real life length in feet is;
= 335/12
= 27.9 feet
6. Speed = Distance / time
The time should be converted to hours;
= 10/60 minutes
= 1/6
Speed = 9 / (1/6)
= 54 miles per hour
= 54 mph

If a figure has been dilated by a scale factor of one third, which transformation could be used to prove the figures are similar using the AA similarity postulate? A translation because it can map one angle onto another since dilations preserve angle measures of triangles. A rotation because it can change the orientation of a figure since dilations do not preserve orientation. A dilation because it can map one side onto another since dilations preserve side length of triangles. A reflection because it can change the orientation of a figure since dilations do not preserve orientation.
Answers
Answer:
A translation can map one angle onto another since dilations preserve angle measures of triangles.
Step-by-step explanation:
A translation transformation could be used to prove the figures are similar using the AA similarity postulate because it can map one angle onto another since dilations preserve angle measures of triangles.
What is translation?In a translation transformation, every point of the figure is moved by the same quantity. This means that the angles and lengths of the figure remain the same. The only thing that changes are the points on which it lies.
The transformation that could be used to prove the figures are similar using the AA similarity postulate is given below:Translation transformation is the correct answer. This is because, in translation transformation, only the cartesian coordinates of the figure change. Nothing happens to the angles and lengths of the figure.
In the other given transformations, the orientations of the figures are not preserved and this makes it harder to prove using the AA similarity postulate.
Therefore, we have found that a translation transformation could be used to prove the figures are similar using the AA similarity postulate because it can map one angle onto another since dilations preserve angle measures of triangles.

A circular coin has circumference 32 pi millimeters. Will the coin fit through a slot that is 35 millimeters long? Explain.
Answers
Answer:
Yes it will
Step-by-step explanation:
A circular coin has circumference 32 pi millimeters. Will the coin fit through a slot that is 35 millimeters long? Explain.
The formula for the circumference of a circle = πD
Where D = Diameter which can also be referred to as the length of the circle
Circumference =32π mm
Hence:
32π = πD
Cancel out the π
D = 32 mm
The diameter of the coin = 32 mm
The length of the slot = 35 mm hence, the coin with a diameter of 32 mm can fit into the slot
