Answer:
see explanation
Step-by-step explanation:
f(x) is valid for all real values of x , so
domain is x ∈ R
Since the coefficient of the x² term < 0 , then
f(x) has a maximum vertex at (0, 5 )
range is ( - ∞ , 5 ]
Answer:
2 is the asnwer hard to explain have a good TEST!!
Step-by-step explanation:
Answer:
relationship between hypotenuse and perpendicular is given by sin angle
sin60=p/h
√3/2=a/16
√3/2×16=a
8√3=a
option C is your answer
Answer:
a = 4
Step-by-step explanation:
Assuming you require to find the value of a
In a rhombus all the sides are congruent, thus
9a - 13 = 3a + 11 ( subtract 3a from both sides )
6a - 13 = 11 ( add 13 to both sides )
6a = 24 ( divide both sides by 6 )
a = 4
Then
XW = 9a - 13 = 9(4) - 13 = 36 - 13 = 23
Thus the sides of the rhombus are 23 units
