What is the value of x in the diagram?
dalvyx [7]

Answer:

x = 30

Step-by-step explanation:

here 50 is hypotenuse as it is opposite of 90 degree.

x and x + 10 are the two other smaller sides of a right angled triangle respectively.

using pythagoras theorem,

a^2 + b^2 = c^2

x^2 + (x + 10)^2 = 50^2

x^2 + x^2 + 20x + 100 = 2500

2x^2 + 20x + 100 = 2500

2x^2 + 20x + 100 - 2500 = 0

2x^2 + 20x - 2400 = 0

2(x^2 + 10x - 1200) = 0

x^2 + 10x - 1200 = 0

x^2 + (40 - 30) - 1200 = 0

x^2 + 40x - 30x - 1200 = 0

x(x + 40) - 30(x + 40x) = 0

(x + 40)(x - 30) = 0

either x + 40 = 0          OR x - 30 = 0

x = 0 - 40

x = -40

x - 30 = 0

x = 30

x = -40,30

since the length and distance is not measured in negative ur answer will be 30

Rus_ich [418]
First, let's divide 810 by 3.

810/3= 270

Then we divide 270 by the number of shelves 5. 

270/5= 54

The answer is 54.

How does the graph of g(x) = −(x + 3)^4 compare to the parent function of f(x) = x^4
kotykmax [81]

Answer: Option D

g(x) is shifted 3 units to the left and reflected over the x-axis.

Step-by-step explanation:

If we have a main function f (x) = x ^ 4

And we perform the transformation:

g (x) = f (x + h) = (x + h) ^ 4

Then it is fulfilled that:

If h> 0 the graph of f(x) moves horizontally h units to the left

If h the graph of f(x) moves horizontally h units to the right

If we have a main function f (x) = x ^ 4

And we perform the transformation:

g (x) = -f(x) = -x ^ 4

Then it is fulfilled that:

The graph of g(x) is equal to the graph of f(x) reflected on the x axis

In this case we have to:

g(x) = -(x + 3)^4 and f(x) = x^4

Therefore h=3>0 and g(x) = -f(x)

This mean that: g(x) is shifted 3 units to the left and reflected over the x-axis.
