irina [24]3 years ago
4 0

Answer:

Jill gets €18 Gary gets €45.

Step-by-step explanation:

First you add the two numbers of the ratio together. 2+5=7. Then you divide the constant, 63, by the total of the ratio, 7. 63/7=9. Then you multiply each number of the ratio by the quotient. 2 x 9= 18. 5 x 9= 45.

Eginning at 15,000 feet, a commercial jetliner begins climbing at a rate (in feet per minute) given by f(t)=e0.4t+8 f ( t ) = e
nydimaria [60]

Answer:

16,126 ft

Step-by-step explanation:

Using the net change theorem and letting s(t) represent the aircraft's position, and s(0) be the aircraft's position at time t = 0, s(0) = 15000 ft  and s(15 be the aircraft's position at time, t = 15 minutes respectively, then,

s(15) - s(0) = ∫₀¹⁵f(t)dt

s(15) - s(0) = ∫₀¹⁵[e^{0.4t}  + 8]dt

s(15) - 15000 = [\frac{e^{0.4t}}{0.4}   + 8t]₀¹⁵

s(15)  - 15,000 ft = \frac{e^{0.4X15}}{0.4}   + 8X15 - \frac{e^{0.4 X 0}}{0.4}   + 8(0)\\\frac{e^{6}}{0.4}   + 120 - \frac{e^{0}}{0.4}   + 0\\\frac{403.43}{0.4}   + 120 - \frac{1}{0.4}   + 0\\1008.57 + 120 - 2.5\\1126.07

s(15) = 15,000 ft + 1126.07 ft

s(15) = 16,126.07 ft

s(15) ≅ 16,126 ft to the nearest foot
