The answer would be three inches per year or B. Hope this helped :)
The eqution of height y in terms of the time x is
We are asked when the rocket will strike the ground, so that is the same that sayin when will the rocket's height will be zero again, that is, y=0. so we have to solve
the solutions of this equations are
So, the rocket will strike the ground after 7.3 seconds
36-8 is 28 which is Haruki's distance and his distance minus 3 is delilahs distance which is 25 meters
The angle between the legs of length 16 and 18 has measure 90 + 55 = 145 degrees.
Now use the law of cosines: it says satisfies
and solving for gives
so the answer is C.
We can write 630 in expanded form as:
630 = 600 + 30 + 0
and in words:
630 = 6 hundreds, 3 tens and zero ones
the value 6 is 600
and the place value of 3 is 30 and the face value is 3 in the number 630.
