Answer:
Step-by-step explanation:
For a parabolic equation to NOT contain the point (0,0) it must have a numeric constant independent from both x and y variables, so the general form would be as follows:
Solving the equation for the point (1,1) would give the necessary value for the constant "c" to make the equation valid:
Therefore, the equation that meets both of the required conditions is:
Answer:
I agree that this question can be confusing:
Apparently point A and point B must be on the same straight line (measured from the light house or the question would be nonsensical)
tan 13 = H / DA where H is height of lighthouse
tan 8 = H / DB tangent measured from point B
tan 13 / tan 8 = DB / DA
DB = .2309 / .1405 * 1279 = 2101 ft
DB - DA = 2101 - 1279 = 822.0 ft

Answer:
7.5
Step-by-step explanation:
QP is 2UT so 10÷2= 5
MQ is 2RU so 15÷2=7.5
