Y = -x^2 + 4x<br><br> quadratic formula
marin [14]

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 )

Find the angle of XZY
qaws [65]

Answer:

<h2>23.6°</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • trigonometry i.g sin(x)=opp/hypo
  • PEMDAS
<h3>given:</h3>
  1. opp:6
  2. hypo:15
<h3>to find:</h3>
  • xyz angle

<h3>let's solve:</h3>

let \: xyz \: angle \: be \:  \alpha

according \: to \: the \: question

\sin( \alpha )  =  \frac{xy}{zy}

\sin( \alpha )  =  \frac{6}{15}

\alpha  = asin( \frac{6}{15} )

\alpha  =  {23.6}^{o}

therefore

<h3>xyz angle=23.6°</h3>

The mode interval in a histogram is the interval that has the highest frequency.
raketka [301]
This is true. 

When we're talking about the mode, we're usually talking about the number which has the highest frequency in a given set of numbers. For example, out of the numbers:

1 2 3 4 5 6 5 4 5 5 5 

5 will be the mode.
