Answer:
Step-by-step explanation:
we want to figure out a value of a for the following condition
to do so factor out v;
divide both sides by v which yields:
therefore,
now,add h to both sides:
further simplification if necessary:
Current area is 5ft * 10ft = 50ft^2.
Increasing by x, you have:
Since length must be positive,
ANSWER:
Let hypotenuse be h.
On using trigonometric function, we get.
sin52° = 12/h
0.788 = 12/h
h = 12/0.788
h = 15.2 rounded.
Step-by-step explanation:
Since the first coordinates are both (0,0) it implies that the line passes through the origin.
The slope of the line is therefore 5/8
The equation:
y-0=5/8(x-0)
y=5/8x
At 2:30, they are 70 miles away, at 2:45, they are 55 miles away.
That means, in 15 minutes, they traveled 15 miles....thats 1 mile per minute.
so 2:45....55 miles away...at 1 mile per minute = 2:45 + 55 minutes =
3:40. <== when they arrive at Grandma's house.
3:40 - 1:00 = 2:40.....it took 2 hrs and 40 minutes for the trip....thats 120 + 40 = 160 minutes <== =so the family lives 160 miles from Grandma's house
