A 300 kg dragster accelerates from the rest to the final speed of 120 m/s in 400 m (about a quarter of a mile) and encounters an

average frictional force of 1200 N. What is the average output in watts AND horsepower if this takes 7.30 seconds?

I don't know about horsepower but I know power.
Power output=(force*distance)/time
=(1200N*400m)/7.3s
=65 753.42466W (watts)

Evaluate the limit, if it exists. (if an answer does not exist, enter dne.) lim h → 0 (−6 + h)2 − 36 h
Lyrx [107]
The limit can be found by simplifying the expression.
\lim\limits_{h\rightarrow 0}\left(\dfrac{(-6+h)^{2}-36}{h}\right)=\lim\limits_{h\rightarrow 0}\left(\dfrac{-12h+h^{2}}{h}\right)\\\\=\lim\limits_{h\rightarrow 0}(-12+h)\\\\=-12

The limit is -12.

\250 doctors from three countries in Europe meeting in a conference to decide whether to approve a new vaccine for the flu. Amon
Bezzdna [24]

Answer:

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Step-by-step explanation:

(a) What is the probability that a randomly chosen doctor is in favor of the vaccine

75% of 115/250 = 0.46(German).

60% of 65/250 = 0.26(French).

65% of 70/250 = 0.28(Englishmen). So

p = 0.75*0.46 + 0.6*0.26 + 0.65*0.28 = 0.683

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Dots sells a total of 277 T-shirts ($2) and shorts ($3). In April, total sales were $656.
icang [17]

Answer:

Shorts = 112 and t shirts = 165

Step-by-step explanation:

Let S = shorts

Let T = t shirts

T + S = 277

$2T + $3S = $656

-2(T + S) = 277          so    -2T -2S = -544

2T + 3S = 656          so      2T + 3S = 656

                                         ------------------------

SO:  (subtract T's cancel out)   1S = 112

                                           divide by 1  so S = 112

Plug S into the top equation: T + s = 277   T + 112 = 277  so T = 165
