Answer:
26
Step-by-step explanation:
First substitute x for 9
Then your problem is m(9)=2(9)+8
Now it is m(9)=18+8
Then add 18 and 8 for 26
Answer:
26
Answer:
y = 2 (x + seven-halves) squared minus one-fourth [y = ]
Step-by-step explanation:
We know that,
vertex form is y = a(x-h)² + k
vertex is (h, k)
Now,
Given that the equation is -
y = (x+3)² + (x+4)²
= x² + 3² + 2×3×x + x² + 4² + 2×4×x
= x² + 9 + 6x + x² + 16 + 8x
= 2x² + 14x + 25
=
=
=
=
∴ we get
The vertex form is -
y =
So,
The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y = )
Call the hypotenuse of the 60° triangle "y". Then the definition of the sine function tells you
... sin(60°) = (8√2)/y
or (multiplying by y/sin(60°))
... y = (8√2)/sin(60°) = (8√2)/(√3/2) = (16/3)√6
Similarly, the definition of the sine function applied to the larger triangle tells you
... sin(45°) = y/x
or
... x = y/sin(45°) = ((16/3)√6)/(1/√2) = (32/3)√3 . . . . matches selection C.
