Answer:

Step-by-step explanation:
We need to find the distance between the points (5, 2) and (1, 9). In order to do this, we will use something called the distance formula. The distance formula is written as follows:

Now we need to plug in our points which we have given in the form (x, y):

Next, perform the operation of subtraction inside the parentheses to simplify:

The exponent is the next step in the order of operations, so square 4 and -7:

Finally, add 16 to 49:

The square root of 65 cannot be simplified further, but an approximation can be made.

Answer:
8x-24
Step-by-step explanation:
8(x-3)
8 times x= 8x
8 times-3= -24
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x and cos²x = 1 - sin²x
Consider the left side
← expand numerator/denominator using FOIL
=
= 
= 
= 
= cot²A = right side , thus proven

for every 3 ounces of flour, you need 2 ounces of sugar
42 km/h is equal to 0.00724933 m/s
You get this by dividing the km/h speed value by 1.609 to get it to m/h, then divide that by 60, then by 60 again to get it to m/s.
