Answer:
x = 14.02 units
Step-by-step explanation:
Finding unknown value using Pythagorean theorem:
This is an isosceles trapezium. The two perpendiculars divide the trapezium into two congruent triangles and a rectangle. Let the base of the triangle by 'y'. We can find the value of 'y' using Pythagorean theorem.
In ΔABC,
AC² = AB² + BC²
19² = 17 ² + y ²
361 = 289 + y ²
361 - 289 = y ²
y ² = 72
y =√72
y = 8.49
x = 31 - 8.49 - 8.49
x = 14.02
Answer:
Option C. y= ( -x)^2 -4
Step-by-step explanation:
If we have a function and we want to transform it into a function g(x) that is equal to f(x) displaced c units down on the y-axis, then we must do:
In this case we want to move the function 4 units down, then:
Finally, to reflect the function on the y-axis. must do
Then we have the following function:
The answer is option C
