Answer:
4.3
Step-by-step explanation:
Apply trigonometric ratios to find the answer.
Firstly, we need to find the measure of angle theta. In order to do this, we will use triangle BAD.
From angle theta, the trigonometric ratio sine can be used:
sinθ = 
After we find the value, we take the inverse sine of it and the result is approximately 50.7 degrees.
Now, knowing that angles BAD and CAD are the same, we can solve for CD using trigonometric ratio sine.
sin50.7 = opposite/hypotenuse
sin50.7 = CD/5.5
sin50.7 * 5.5 = CD
4.3 ≈ CD
Answer:
r = - 7
Step-by-step explanation:
The common ratio r is the ratio of a term to the preceding term, that is
r = 126 ÷ - 18 = - 882 ÷ 126 = - 7
The number 0 is basically nothing, so 7 divided by nothing is not defined. That's why calculators or even the most powerful computer can't divide anything by 0
Answer:
No
Step-by-step explanation:
No
Because a linear function is the form as

the highest exponent is one
and the graph is a line in the case of

is a parabola, not a line
