Evaluate the expression when the value of the variable is given. 40 - 8x when x = 2
Ede4ka [16]

Answer:

24

Step-by-step explanation:

To evaluate this, we just need to substitute 2 for whenever we see x.

40 - 8 (2)

From here, we can just use order of operations to simplify it down to a single number.

40 - 16

24

So, when x = 2, we get 24.

The time of a pendulum varies as the square root of its length. If the length if a pendulum which beats 15seconds is 9cm, find t
8090 [49]

Answer:

length= 3.7 ft.

Step-by-step explanation:

T= (square root of length) * k

1.8 seconds = (square root of 3) * k

k= 1.8 seconds / (square root of 3)

a.) T= (square root of 11) k

substituting k:

T=(square root of 11) * 1.8 seconds / (square of 3)

T= 3.4 seconds

b.) 2 seconds = (square root of length) k

substituting k:

2 seconds =(square root of length) 1.8 seconds / (square root of 3)

Divide the equation by 1.8 seconds / (square root of 3):

2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)

10(square root of 3) / 9 = (square root of length)

square both sides:

100/7 ft= length

length= 3.7 ft.

Hope this helps.
