Public debt in example 5 of section 2.3, the federal debt held by the public as a percent of the gross domestic product (gdp) was modeled by the function
y=0.00630t^3-0.289t^2+4.00t+25.3
where t was the time (in years) since 1980. source: budget of the u. s. government.
(a) find the average public debt, as a percent of gdp, from 1990 to 2000.
(b) find the average public debt, as a percent of gdp, from 2000 to 2015.

answer:

bbj

step-by-step explanation:

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
