Mathematics
1 answer:
marta [7]3 years ago
6 0

Answer:

first three terms are

-1, -1/2 & 0

Step-by-step explanation:

here,

a=-1

and d=1/2

so

t1 = -1

t2 = a+(n-1)d= -1 +(2-1)*(1/2)=-1/2

t3= a+(n-1)d= -1 +(3-1)*(1/2) =0

This exercise uses, the population growth model
timofeeve [1]

P is equal to 8700% for population x time in hours.

<h3>What is population growth model?</h3>

P is equal to 8700% for population x time in hours. 2Ae%5E%28kx%29

K's model must be solved. ln%28p%29=ln%288700%29%

2Bkx%2Aln%28e%

29\skx%

2A1=ln%28p%29-ln%288700%

29\sk=%281%

2Fx%29%

28ln%28p%29-ln%288700%29%29

Replace the point (1,10000).

k=%281%

2F1%29%

28ln%2810000%

29-ln%288700%

29%

29\sk=ln%2810000%

29-ln%288700%

29 k=0.13926, which you might only desire to three or maybe even two significant figures.

You may just enter 10000% if you want p after two hours.

And it SHOULD be the same as 8700% (2810000%2F8700%).

Just give it a shot and see, 2Ae%5E%280.139%2A2%29. More particular, the model is highlighted by p=8700%. 2Ae%5E%280.139% 2Ax%29% 29.

Determine how long to double x.

Take the logs on both sides, then find x.

To put it more simply, start with this form: 2=1%2Ae%5E%280.13926%2Ax%29

Without looking, Santiago took a handful of multi-colored candies from a bag and found that 20% of the candies were yellow and 1
ehidna [41]
There are 24 more yellow candies than green. 480 x .20 = 96, while 480 x .15 = 72. 96-72 = 24

I really need help with this trigonometry problem, can someone please help me
mr_godi [17]
Not sure if you wanted the exact value or the degrees. Here’s both:


1: sin pi/3 = 60° or sqrt of 3 over 2

2: cos 2pi/3 = 120° or -1/2

3: tan 7pi/4 = 315° or -1

4: tan 5pi/6 = 150° or -sqrt of 3 over 3

5: sin 7pi/6 = 210° or -1/2

6: cos 11pi/6 = 330° or square rt of 3 over 2

Formula I used:
Problem (example: 11pi/6) times 180° over pi.
