Let x is the days and the y is the height of the plant.
Let the change between x and y is linear.
So, the relation between x and y will take the form ⇒ y = ax + b
where a and b are constants.
At x = 30 ⇒ y = 18 ⇒⇒⇒ ∴ 18 = 30 a + b → (1)
At x = 90 ⇒ y = 29 ⇒⇒⇒ ∴ 29 = 90 a + b → (2)
solve (1) and (2) to find a and b
subtract (1) from (2)
∴ 11 = 60 a ⇒⇒⇒ ∴ a = 11/60
substitute at (1) ⇒⇒⇒ ∴ b = 25/2 = 12.5
<u>So, the equation which represents the plants growth is</u>
<u>∴ y = (11/60) x + 12.5</u>
Answer:
56 quizzes
Step-by-step explanation:
40 quizzes = 5 weeks
To find the unit rate of quizzes / week, we can divide both sides by 5
40/5 quizzes = 5/5 weeks
8 quizzes = 1 week
Multiply both sides by 7 to find the amount of quizzes in 7 weeks
8 * 7 quizzes = 1 * 7 weeks
56 quizzes = 7 weeks
Answer: The length of third side is 15.
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The perimeter of given triangle is 44.
One side, suppose a is 18.
Second side, suppose b is 11.
Suppose, third side is c.
So the perimeter will be :
Subtracting 29 in both sides
Hence the length of third side is 15. Answer
Hope it will help :)
