There are numerous important information's already given in the question. Based on these information's, the answer can be deduced.
Let us assume the age of Daniel = x years
Let us assume the age of Kevin = y years
Then
y = 4x
and
y = x + 6
So
4x = x + 6
4x - x = 6
3x = 6
x = 6/3
= 2 years
So
Age of Kevin = 4 * 2 years
= 8 years
Step-by-step explanation:
1-2cos²c.
> (cos²c+sin²c)-2cos²c. (cos²c+sin²c=1)
> cos²c+sin²c-2cos²c
> sin²c-cos²c.
is your correct answer.
hope this helps you.
Answer: H = 3t + 8
Step-by-step explanation:
Given the following :
Initial height of plant = 8 inches
Rate of growth = 3 inches per month
Let H = height of plant ; t = time in months
Expression to represent the height, H, t months after purchase ;
Height of plant after t months will be ;
Initial height which is a constant is added to the rate of growth multiplied by the number of months after purchase.
Mathematically,
H = 8 + (3 × t)
H = 3t + 8
Answer:
