Answer: C (x, y) ➔ (0.375x, 0.375y)
Answer:
x=2 and -2
Step-by-step explanation:
f(x)=2x^2-8
set the function equal to zero to solve for x
2x^2-8=0
add 8 to both sides and divide by 2
x^2=4
take the square root of both sides to get x isolated
√(x^2)=√4
x= ±2
We have a triangle:
the side opposite the angle Ф is 4/5,
The side adjacent the angle Ф is 3/5
1) we calculate the hypotenuse, by the Pythagoras Theorem:
h=√[(4/5)²+(3/5)²]=1
2) we calculate the csc of Ф
csc Ф= hypotenuse / opposite side
csc Ф=1/ (4/5)=5/4
Answer: e. 5/4
