IMPOSSIBLE MATH QUESTION(1+tan (1))(1+tan (2))(1+tan (3))(1+tan (4))...(1+tan (45))=?
find the value

Answers

well u can also do this without a calculator
take $tan 1=tan(45-44)=(1-tan44)/(1+tan 44)$
then
$(1+tan1)=(1+ (1-tan44)/(1+tan 44))=(2)/(1+tan 44)$
therefore similarly
$(1+tan 1)(1+tan 2)...(1+tan 22)= (2)/(1+tan 44) (2)/(1+tan 43)(2)/(1+tan 42)..(2)/(1+tan 23)$
$= (2^(22))/((1+tan 44)(1+tan 43)(1+tan 42)...(1+tan 23))$
then $(1+tan 1)...(1+tan 45)= (2^(22))/((1+tan 44)(1+tan 43)(1+tan 42)...(1+tan 23))(1+tan 23)(1+tan 24)...(1+tan 45)$
$=2^(22)(1+tan45)=2^(23)=8388608$

(1+tan 1)(1+ tan 2)...(1+tan 45)=(1+0.017455)(1+0.03492)...(1+1)=8388608.11

How can i show my work for 2x-4= -10+x

Answers

Let me help you with that :)

2x - 4 = - 10 + x (we transfer the x from the right side, and transfer the - 4 from the left side)

2x - x = - 10 + 4 (we calculate this)

x = -6

And that is the answer; x = - 6 :)

Tania bought 4 more pounds of pears than Wilma. Together, Tania and Wilma bought 18 pounds of pears. How many pounds of pears did Wilma buy? need help

Answers

The equation would be (x+4)+x=18. X stands for the amount of pears Wilma bought, and (x+4) is the amount of pears Tania bought (because she bought four more pounds than Wilma).(X+4)+x=182x+4=18 (now you subtract four from both sides)2x=14 (to get x by itself, divide both sides by 2)X=7Wilma bought 7 pounds of pears :3

Number of pears Tania bought - t
Number of pears Wilma bought - w

t = w + 4
t + w = 18

(w + 4) + w = 18
2w + 4 = 18
2w = 14
w = 7

Wilma bought 7 pounds of pears.

t = (7) + 4
t = 11

Tania bought 11 pounds of pears.

20 points!!! plz help asapSuppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30%
arrive late. Valerie used the random-number table to find the experimental probability that of 5
flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,
4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving
late. Find the experimental probability that of 5 flights at least 2 will arrive late.
A: 3/10
B:2/5
C: 9/20
D: 11/20

Answers

Answer:

D. 11/20

Step-by-step explanation:

7, 8, and 9 represent late flights. We want to count how many of the 20 trials have at least two of these digits. Counting, we find that 11 of the 20 have at least two of these digits.

Tell whether the 2 rates form a proportion:a) 28 points in 3 games, 112 points in 12 games
b) 32 notes in 4 measures, 12 notes in 2 measures
Show work if you can please :)

Answers

Final answer:

The rates 28 points in 3 games and 112 points in 12 games form a proportion, while the rates 32 notes in 4 measures and 12 notes in 2 measures do not form a proportion.

Explanation:

To determine whether the given rates form a proportion, we need to check if the ratios are equivalent. a) We'll start with 28 points in 3 games vs 112 points in 12 games. The ratio 28/3 equals approximately 9.33, and the ratio 112/12 also equals approximately 9.33. Since these ratios are equal, these rates do form a proportion. b) Moving to 32 notes in 4 measures vs 12 notes in 2 measures. The ratio 32/4 equals 8, and the ratio 12/2 equals 6. Since these ratios are not equal, these rates do not form a proportion.
