Please help me:( I’m not very good with parabolas

Mathematics
1 answer:
steposvetlana [31]3 years ago
3 0

Answer:

Direction of the parabola: Down

Step-by-step explanation:

The value of the coefficient of x² (represented by <em>a </em>) determines whether the graph opens up or down.

* If <u><em>a</em></u> is positive, the graph opens <u>up</u>.

* If <u><em>a</em></u> is negative, the graph opens <u>down</u>.

Since the coefficient of  x² is -1, then it means that the graph of the parabola opens <u>downward</u>.

We use the distance formula for this problem.

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

The distance between point (-2,-2) and point (-2,4).
d = √[(⁻2 - ⁻2)² + (4 - ⁻2)²] = 6 units

Then, compute for 20% of 6 units:
Distance traveled = 6(0.2) = 1.2 units

Use 1.2 units as distance and the starting point (-2,-2). The x-coordinate should still be at -2 because the distance is a straight line as shown in the picture.
1.2 = √[(-2 - ⁻2)² + (y - ⁻2)²]
Solving for y,
y = -0.8

The point is found at (-2,-0.8). This is located at quadrant 3. As to the distance traveled, that would be: 1.2*6 = 6 miles. Thus, the answer is C.

There are 32 students in a class. Nine of those students are women. What percent are men?
QveST [7]

Answer:

72%

Step-by-step explanation:

you can divide part of a whole by the whole to get a decimal

this decimal is the percentage when you move the decimal 2 places to the right

32 - 9 = 23 men

23/32 = .72 (rounded)

.72 = 72%

A betta fish tank is in the shape of a cube. The volume of the fish tank is 216
GarryVolchara [31]

To find this answer, we need to understand how to get the Volume.

We get the volume by the formula: L x W x H

L = Length

W = Width

H = Height

So, we can see that there are 3 units required to know for getting the volume, if that's true, then, to do the inverse operation of finding the volume. That can be done by using thie formula:

V=a^3

a= edge

Solving for a

a=V⅓=216⅓=6

<h2>So hence, each of the Cube shaped Fish Tank is 6in³</h2>

now, let's look at how to find whether our answer is right or wrong

6x6=36

36x6=216

So hence, our answer is right!
