Step-by-step explanation:
I'm assuming you didn't mean to repeat each number 3 times.
If she did 184 jumping jacks in 4 minutes that means she did 46 jumping jacks per minute.
Given:
Dimensions of Kendra's yard are 24.6 feet by 14.8 feet.
To find:
The area of her yard.
Solution:
Let as consider,
Length of yard = 24.6 ft
Width of yard = 14.8 ft
We know that,
Area of a rectangle = Length × Width
Using the above formula, we get the area of her yard.


Area of her yard is 364.08 ft² and without including the units ft², we get 364.08.
Therefore, the area of her yard is 364.08.
The direct variation equation is y =kx
Lets see:-
4y/4 = x/4
y = 1/4x
<span>Answer: Yes, this is a direct variation </span>
So discriminant gives us 3 possibilites connected with result of the equation b^2-4ac. If it is bigger than zero, there are 2 solutions, if answer is exactly 0, then there is one answer and if the number is lower than 0, there are no solutions.
Discriminant of your quadratic equation is (-4)^2-4*1*5=16-20=-4, so there are no solutions.
