A) okay so let x represent how old the friend is now. And 4 represent the years added on. If you have to be LESS then 18 years old to be in boy scouts, and the friend is still able to be in boy scouts after four years, then It can be modeled by x + 4 < 18
B) wrote down number values with 18 being in the middle. Plot a dot on the number 18 (with an open circle. Not filled in circle. A filled in circle means equal to and it is not equal to.) and since you have to be LESS then 18, you should draw a line going left to the smaller numbers of 18.

I hope this helps??

Isosceles triangle ABC has a perimeter of 96 centimertes the base of triangle AC and the mesurments at 24 centimeters. what is t

Novosadov [1.4K]

Answer:

AB= 36 degrees

Step-by-step explanation: AB + BC + AC = 96

but AB = AC [isosceles triangle]

2AB + 24 = 96

2AB = 96 - 24 = 72

AB = 72/2 = 36

AB = 36 degrees.

True or false: the range of y=arcsinx is [-pi/2, pi/2]

balandron [24]

True.

The range for arctan is all the valid Y-Values, and if you take a look at the graph you can see it caps out at pi/2 and -pi/2 for y values.

P.S. pi/2 = 1.57......

Answer:

<em>Probability ≈ 0.1071</em>

Step-by-step explanation:

Consider steps below;

$Total Possible Outcomes - 8C5,\\\\8! / 5! ( 8 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 / ( 1 * 2 * 3 * 4 * 5 )( 1 * 2 * 3 ),\\\\6 * 7 * 8 / 6 = Combinations - 56,\\\\$

$Number Of Outcomes - 6C5,\\\\6! / 5! ( 6 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 / ( 1 * 2 * 3 * 4 * 5 ) ( 1 ),\\720 / 120 * 1,\\\\Outcomes - 6$

$Conclusion ; Solution - 6 / 56 = ( About ) 0.1071\\Hope That Helps!$

<em>Solution; Probability ≈ 0.1071</em>

A line passes through the point (–6, –2), and its y-intercept is (0, 1). What is the equation of the line that is perpendicular

Mama L [17]

The slope of first line is m 1= ( 1 - 0 ) / ( - 2 - ( - 6 ) );
m = 1 / 4 ;
Because the second line is perpendicular to the first line, m2 * m1 = - 1 ;
m2 * ( 1 / 4 ) = -1;
m2 = - 4 ;
The equation of the second line is : y - 3 = ( - 4 )( x - 2 );
y - 3 = -4x + 8 ;
y = -4x + 11.
