Answer:
d(t) = 1 +1.5*a(t)
Step-by-step explanation:
Since point D is launched from a platform that places it 1 meters from the wall, we have
d(0) = 1
Since point A is launched directly from the wall,
a(0) = 0
but besides, point D travels 1.5 times as fast as point A, so
d(t) = 1 +1.5*a(t)
and this the function required.
Answer:
Step-by-step explanation:
Isaiah Let's solve this by rewriting the actual measurements the two boys have with their uncertainties. Krisann has a measuring tape to the nearest quarter inch. So his measurement may be off by half that, or and eighth of an inch. So his measurement is 27.75 ± 0.125. Isaiah has a measuring tape to the nearest eighth inch. So his measurement may be off by up to a sixteenth of an inch. So his measurement is 27.75 ± 0.0625 Now which is more precise, 27.75 ± 0.125, or 27.75 ± 0.0625? The answer is pretty obvious with 27.75 ± 0.0625 being the more precise measurement. And that value is from Isaiah.

Answer: Rewrite equations:
5x+y=−13;6x+6y=−6
Step: Solve5x+y=−13for y:
5x+y=−13
5x+y+−5x=−13+−5x(Add -5x to both sides)
y=−5x−13
Step: Substitute−5x−13foryin6x+6y=−6:
6x+6y=−6
6x+6(−5x−13)=−6
−24x−78=−6(Simplify both sides of the equation)
−24x−78+78=−6+78(Add 78 to both sides)
−24x=72
−24x
−24
=
72
−24
(Divide both sides by -24)
x=−3
Step: Substitute−3forxiny=−5x−13:
y=−5x−13
y=(−5)(−3)−13
y=2(Simplify both sides of the equation)
Answer:
x=−3 and y=2
