Answer:

3cm/s

Step-by-step explanation:

Area of a square is expressed as:

A = L²

Rate of change of area is expressed as:

dA/dt = dA/dL•dL/dt

Given that

dA/dt = 24cm²/s

L = 4cm

Required

dL/dt

Since dA/dl = 2L

dA/dl = 2(4)

dA/dl = 8cm

Subatitute the given values into the formula

24 = 8 dL/dt

dL/dt = 24/8

dL/dt = 3cm/s

How many different four-digit numbers can be made using the digits 1,2,3,4,5,6 if no digit can be used more than once?
igomit [66]

Answer:

360

Step-by-step explanation:

The given digits are 1,2,3,4,5,6.

So, total number of digits = 6.

We need to find the number of different ways to form four-digit numbers using the digits, without repetition.

Total ways for first place = 6

After selecting 1 digit the number of remaining digits is 5. So,

Total ways for second place = 5

Similarly,

Total ways for third place = 4

Total ways for forth place = 3

Total number of ways = 6\times 5\times 4\times 3=360

Therefore, 360 four digit numbers are possible.

Help I will be marking brainliest!!!
Margarita [4]
You use the tan/cos/sin rules

So we know that the hypotenuse=46.8, opposite=44

We can use sin (negative) to find it

sin^-1=opp/hyp
sin^-1=44/66.8
=70 degrees

Hope this helps!! :)
