Answer:
9x - 9
Step-by-step explanation:
6x + 3x = 9x. 1- 10 = -9
Combine the like terms
F(t) = 200(0.95)^t = 200(1 - 0.05)^t
<span>rate is 5% decay per unit of time.
Hopefully that is correct & I hope I helped :)</span>
Answer: 60000
Step-by-step explanation:
The ten thousands place is the 5th digit from the right. Because the digit in the thousands place is less than 5, round down to 60000.
Answer:
Step-by-step explanation:
The total surface area of a cone is given by:
Surface area = 
where r is the radius of the cone, h is the height of the cone, l is the length of the cone = 
Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:
C
the square of the sum of 7 times x and 3 is expressed as
7x + 3 ← the sum of 7 times x and 3
(7x + 3)² ← the square of the sum of 7 times x and 3
4 times the difference of x and 1 is expressed as
x- 1 ← the difference of x and 1
4(x - 1) ← 4 times the difference of x and 1
putting it all together gives
(7x + 3 )² / 4(x - 1 ) → C
