Answer:

Step-by-step explanation:

3 hrs to travel 45 miles downstream

4 hrs to travel 28 miles upstream

speed of boat in still water= s

speed of the current= c

s+c= 45/3= 15
s-c= 28/4=7

added up the 2 equations, we get:

2s= 22
s= 11 mph
c= 4 mph

Suppose that YM has a length of 12in and its distance from point L is 5in find the radius of circle L to the nearest tenth

sashaice [31]

We know that
applying the Pythagoras theorem
LM²=LV²+VM²
LM is the radius of the circle
LV=5 in
VM=12/2----> 6 in
so
LM²=5²+6²-----> LM²=61------> LM=7.81 in------> LM=7.8 in

the answer is
7.8 in

The midpoint of AB is M(7,-2). If the coordinates of A are (8,3), what are the<br> coordinates of B?

strojnjashka [21]

Answer:

Step-by-step explanation:

We can find it like:

$x_{B}= 2x_{M}- x_{A} = 2*7 - 8 = 14 - 8= 6\\ \\y_{B}= 2y_{M}- y_{A} = 2*(-2) - 3 = - 4 - 3= - 7$

The answer is B(6,-7).

Hope you understand.
