1  True   because 19^3  = 6859
2. False
3. True because 8000 ^1/3  can be written as 100^1/3 * 8^1/3
4 False 
5 True because they are both = 15

Use the point-slope form from the previous question and fill-in the following table of values.
matrenka [14]

Answer:

Step-by-step explanation:

Slope of line through (0,-1) and (1,2) = (-1 - 2)/(0 - 1) = 3

Point-slope equation for line of slope 3 that passes through (0,-1):

y+1 = 3(x-0)

When x = 2:

y+1 = 3(2-0)

y = 3·2 - 1 = 5

When x = 3:

y+1 = 3(3-0)

y = 3·3-1 = 8

Find the point on the curve y = √ x where the tangent line is parallel to the line y = x 8 .
vichka [17]
If tangent to the curve y = √x  is parallel to the line  y = 8x,  then this implies that the tangent to  y = <span>√x  has the same slope as the line  y = 8x. In other words, the derivative (slope) function of  y = √x  is equal to the slope of the line  y = 8x, which is m = 8.  Hence y' = 8  once we find  y'

y =  </span><span>√x = x^(1/2)

Applying the power rule and simplifying, we find that the derivative is

y' = 1/(2</span>√x)

Now remember that  y'  must equal 8

1/(2<span>√x) = 8

Multiplying both sides by  2</span><span>√x,  we obtain

1 = 16</span><span>√x

Dividing both sides by  16,  yields

</span><span>√x = 1/16

But wait a minute, √x = y.  Thus  1/16  must be the y-coordinate of the point at which the tangent to  y = √x  is drawn.

Squaring both sides, yields

x = 1/256 

This is the x-coordinate of the point on the curve where the tangent is drawn.

</span><span>∴ the required point must be  (1/256, 1/16)

GOOD LUCK!!!</span>

PLEASE HELP!!

Hey!
Yes it is because there is a common difference the whole way. A specific number is added to each term.
8-3 is 5 so the answer is A!

Answer:

These are actually pretty easy. So the dots represent 1, hours. The correct answer would be the one under the first box, the one with the first blue box right below the 8 but above the 6. Mark as brainliest, this is correct!
