Answer:

  106 m

Step-by-step explanation:

The law of sines is useful.

The angle opposite the given side of 50 m is ...

  180° -83° -69° = 28°

Then the distance (d) opposite the 83° angle is ...

  d/sin(83°) = (50 m)/sin(28°)

  d = (sin(83°)/sin(28°))×(50 m) = 105.709 m

The ball is about 106 meters from the pin.

Hello,

y=k(x+3/2)²-25/2
and -8=k*9/4-25/2==>9/4k=9/2==>k=9/2*4/9=2

y=2(x+3/2)²-25/2

x- intercepts:
y=0=2(x+3*2)²-25/2
==>(x+3/2)²=25/4
==>x=-3/2-5/2 or x=-3/2+5/2

==>x=-4 or x=1

(-4,0) and (1,0) are x intercepts

Identify the factors of x2 − 4x − 12.
Alborosie
(x-6)(x+2)

When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.

Which choice below is a boxplot for the following distribution? 67, 66, 64, 62, 60, 56, 54, 50, 46, 42, 41, 40, 40, 38, 35, 21,
luda_lava [24]

Answer:

Option E - Box plot E

Step-by-step explanation:

Given : Data,

67, 66, 64, 62, 60, 56, 54, 50, 46, 42, 41, 40, 40, 38, 35, 21, 19

To find : Which choice below is a boxplot for the following distribution?

Solution :

Step 1- Arranging the data from lowest to highest,

{19,21,35,38,40,40,41,42,46,50,54,56,60,62,64,66,67}  

Step 2 - Find the median of the data  

As the data is odd numbers so the median is \frac{n+1}{2} th term.

\frac{n+1}{2}=\frac{17+1}{2}=9th term.

9th term is 46

∴ Q_2=46  

Step 3 - To find Upper quartile and lower quartile  

Lower quartile data set is the median of the upper terms from median

{19,21,35,38,40,40,41,42}

Median of the set is M=\frac{38+40}{2}=39

∴ Q_1=39  

Upper quartile data set is the median of the lower terms from median

{ 50,54,56,60,62,64,66,67}

Median of the set is M=\frac{60+62}{2}=61

∴ Q_3=61  

We have plot the box plot attached below.

Our box plot is matched with Box plot E.

Therefore, Option E is correct.
