marin [14]3 years ago
4 0

Answer:

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Down

Vertex:  

( 2 , 4 )

Focus:  

( 2 , 15 /4 )

Axis of Symmetry:  

x = 2

Directrix:  

y = 17 /4

x              y

0             0

1              3

2             4

3             3

4             0

To find the x-intercept, substitute in  

0  for  y  and solve for  x . To find the y-intercept, substitute in  0  for  x  and solve for  y .

x-intercept(s):  ( 0 , 0 ) , ( − 4 , 0 )

y-intercept(s):  ( 0 , 0 )

Select the statement that correctly compares two numbers.
sattari [20]

The correct answer is option A

• In mathematics, comparison of numbers if the process that defines similar properties between two numbers and identifies that the number if smaller or greater than or equal to the other number.

• In maths there are three special symbols used in comparison of numbers. The basic symbols are

1. Greater than (>)

2. Less than (<)

3. Equals to (=)

According to the question

Option A :

4.13 = 4.130

As we know the value of 0 after all the numbers and after the decimal is insignificant,

So , 4.13 = 4.130

This is correct comparison.

Option B :

5.16<5.06

Bigger number can’t be less than the smaller number, comparison is wrong.

Option C :

6.28<6.08

Bigger number can’t be less than the smaller number, comparison is wrong.

Option D:

7.09>7.19

Smaller number can’t be greater than the bigger number, comparison is wrong.

Option A is correct

What is the equation of the following line? Be sure to scroll down first to see all answer options.
Naddik [55]

Answer:

C

Step-by-step explanation:

Since the graph hits 0 at x = 0, your y intercept is 0.

The graph is decreasing which means you have a negative slope.

They gave you a coordinate so use it to find the slope.

\frac{1-0}{-3-0} = \frac{-1}{3}

That's your slope.

C is the correct answer.
