Answer:x = 75
Step-by-step explanation:y=105 - 5 = 100 ft
z=125 ft
dz/dt=2 ft/sec
by using Pythagorean Theorem, we find x
x^2 + 100^2 = 125^2
x = 75
There are 125 refrigerators in total.
Explanation:
Set up an equation:
x(.40)= 50
, where x is the number of refrigerators
Solve for x
A parabola's axis of symmetry always goes through the vertex of the parabola. In other words, it is a vertical line that goes through the x-coordinate of the vertex. Therefore, the equation of the axis of symmetry for this parabola is x = 0.
Step-by-step explanation:
Since this is a right triangle and we are given an angle measure that measure 45, the other angle measure also measure 45.
So this means we are dealing with a 45-45-90 triangle.
A 45-45-90 triangle legs are equal to each other and the hypotenuse measures sqr root of 2 times more than the legs.
The hypotenuse measure 2 times sqr root of 14 so divide by sqr root of 2 to find x and y.

Since x and y are equal, they both measure
