Answer: x=2
Step-by-step explanation: The axis of symmetry is the x-axis of the vertex which in this case is (2, -1)
Answer:
6=2 , 12=4, 15=5, 24=8
Step-by-step explanation:
Given that the last term is -3x^4, the polynomila is ordered in descending order of the exponent of x. Then, the first term is that where y is with the highest exponent, that is y^4
Simplify the terms with y^4: -2y^4 + 6y^4 = 4y^4
Then the first term is 4y^4
Answer:
y = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = 
sin45° = 
= 
Multiply both sides by y
y × sin45° = 9, that is
y × = 9
Multiply both sides by
y = 9
