Answer:

1 − 2 cos x

Step-by-step explanation:

y' = 2 sin x

y = C − 2 cos x

HELP PLEASE ITS THE ONLY QUESTION I NEED!!
insens350 [35]

Because the order doesn't matter on where each person sits use the combinations formula:

C = n! / (r!(n-r)!)

Where n is the total number of people and r is the number of chairs.


C = 6! / (4!(6-4)!)

C = (6*5*4*3*2*1) / ((4*3*2*1(2*1))

C = 720 / (24*2)

C = 720 / 48

C = 15


There are 15 different arrangements.

8x(5+10)= (8x5) + (5x10)
Slav-nsk [51]

Answer:

i think its x= 0.75

Step-by-step explanation:

substitute:

8x × 5 = 40x

8x × 10 = 80x

8 × 5 = 40

5 × 10 =50

40x + 80x = 40 + 50

add like terms

so it'd be:

120x = 90

now divide 90 by 120 and that would give you the value of x alone which is 0.75

miv72 [106K]

Answer:

x=2y\,,\,3x+4y=70  where x denotes number of small rooms and y denotes number of large rooms

Step-by-step explanation:

Given: Small rooms can hold 3 people, and large rooms can hold 4 people.

Number of small rooms is twice the number of large rooms.

Small rooms and large rooms altogether can accommodate 70 guests.

To find: system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved

Solution:

Let x denotes number of small rooms and y denotes number of large rooms.

As number of small rooms is twice the number of large rooms,

x=2y

As small rooms and large rooms altogether can accommodate 70 guests such that small rooms can hold 3 people, and large rooms can hold 4 people,

3x+4y=70
