First we need to add the time she takes warming and the time she takes going to the the gym:
15minutes+40minutes=45minutes

Next, we area going to subtract those 45 minutes from the time the game begins: 
6:45pm-45minutes=6:00pm

We can conclude that she should leaver her house at 6:00 pm if she wants to get in time for her 6:45 pm game.

Simplify <br> cosx ( tanx+cotx)
Soloha48 [4]
The first step to solving this is to use tan(t) = \frac{sin(t)}{cos(t)} to transform this expression.
cos(x) × ( \frac{sin(x)}{cos(x)} + cot(x) )
Using cot(t) = \frac{cos(x)}{sin(x)},, transform the expression again.
cos(x) × ( \frac{sin(x)}{cos(x)} +  \frac{cos(x)}{sin(x)} )
Next you need to write all numerators above the least common denominator (cos(x)sin(x)).
cos(x) × \frac{sin(x)^{2} + cos(x)^{2}  }{cos(x)sin(x)}
Using sin(t)² + cos(t)² = 1,, simplify the expression. 
cos(x) × \frac{1}{cos(x)sin(x)}
Reduce the expression with cos(x).
\frac{1}{sin(x)}
Lastly,, use \frac{1}{sin(t)} = csc(t) to transform the expression and find your final answer.
csc(x)
This means that the final answer to this expression is csc(x).
Let me know if you have any further questions.

1.)Given the recursive definition LaTeX: a_{n+1}=2\cdot a_n+1a n + 1 = 2 ⋅ a n + 1, and that LaTeX: a_1=1a 1 = 1, find LaTeX: a_
aksik [14]

Answer:

1) 1023

2) 8

Step-by-step explanation:

1)

Given:

a_{n+1}=2\cdot a_n + 1 and a_1 = 1

Then,  the next table can be computed (only the first terms are explicitely shown)

n      a_n

1       1

2      a_{2}=2\cdot 1 + 1 = 3

3      a_{3}=2\cdot 3 + 1 =7

4      15

5      31

6      63

7      127

8      255

9      511

10     1023

2)

Given

t_n=n^2-2n

Then,  the next table can be computed

n      t_n

1       t_1=1^2-2(1) =-1

2      t_2=2^2-2(2) =0

3      t_3=3^2-2(3) =3

4      t_4=4^2-2(4) =8

Aleonysh [2.5K]

Answer:

Answer: 4(p - 7) = 44

First distribute the 4 over the parentheses

4p - 28 = 44

Add 28 to both sides:-

4p = 44 + 28

4p = 72

Divide both sides by 4:-

p = 72/4

p = 18
