Answer:
Obtuse and Isosceles
Step-by-step explanation:
Since there is an angle greater than 90 degrees (104 degrees) the triangle is obtuse. Since there are two congruent sides, the triangle is also Isosceles.
The height of the ball at ground level would be 0 feet.
Set h to 0 and solve for t:
Rewrite the equation as
-5t^2 -2t +49 = 0
Factor -1 out of the equation to get:
5t^2 + 2t -49 = 0
Use the quadratic formula:
-b +/- sqrt(b^2 -4(ac) / 2a
Where a = 5, b = 2 and c = -49
The quadratic formula becomes:
-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)
Simplify to get :
T = -2 +/-sqrt246 / 10
T = 2.936 and – 3.336
Since the time has to be a positive value t = 2.936 seconds.
Rounded to the nearest hundredth = 2.94 seconds.

Answer:
(-infinity, 7]
Step-by-step explanation:
even though it looks like it's split the bottom line includes -1 so it's one domain.
Answer:
m = 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x + 7 is in this form with slope m = - 4
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
=
Hence the value of m =
