Given:
First, just leave the negative sign at the side. You will deal with that later. For now, you focus on solving on the square root of 25. The square root of 25 is a number that when multiplied with itself, equals to 25.
For example, 4x4=16. So, the square root of 16 is 4.
Now, for 25, the answer would be 5. Since 5x5 = 25.
Then, you take the negative sign with the 5. The answer would be
-5.
A reasonable estimate could be any number that makes sense. Say the average elementary student is 4' 10" then a reasonable estimate could be 3' to 3' 6" because the desk would be about a 1' 6" shorter than the person.
Distance = sqrt((6-2)^2 +(8-1)^2)
sqrt(16 +49)
sqrt(65)
8.06
round to 8.1 units
Differentiate using the chain rule:
d/du [ln(u)] d/dx[2x^3+3x]
derivative of ln(u) = 1/u
1/u d/dx[2x^3+3x]
1/2x^3+3x d/dx[2x^3+3x]
Differentiate
(6x^2+3) 1/2x^3+3x
Simplify
Dy/dx = 3(2x^2+1) / x(2x^2 +3)
Answer:
19 cents
Step-by-step explanation:
Natalie buys 4 buttons at 3 cents each. She also buys 1 zipper at 7 cents
We are to find the total amount that she spends for each costume
I converted cents to dollars.
4 buttons at 3 cents = 4x0.03 (3 cents is 0.03 dollars)
= 0.12
The zipper = 7 cents = 0.07 dollars
The total amount she spent = 0.12+ 0.07
= 0.19 dollars = 19 cents
Therefore she 19 cents in total for each costume
4 buttons at
