Answer:
Step-by-step explanation:
Given that,
The area of a square is given by :
A = s² ....(1)
Where
s is the side of the square.
Differentiating (1) wrt s.
Put s = 10 in the above equation.
So, the rate of change of the area of a square is 20 units
Answer:
- <u>200,000</u><em> 6-digit numbers can be constructed.</em>
Explanation:
Since the number is greater than 600,000, the first digit must be 6, 7, 8, or 9, so 4 different options: 4
The second, third, fourth, and fith digits can be either number 0 through 9, so 10 options for each one: 10 × 10 × 10 × 10.
Since the number must be odd and greater than 600,00, the last digit is odd, so it can be 1, 3, 5, 7, or 9, so 5 different options: 5.
Using the multiplication counting principle, you muliply the independent options to obtain the number of different combinations:
- 4 × 10 × 10 × 10 × 10 × 5 = 200,000.
Answer:
sinB = 21/75
tanB = 21/22
Step-by-step explanation:
sinΦ = Height / Hypotenuse
tanΦ = Height / Base
