Answer:
The greatest possible error for the measurement 3.2 cm is 0.05 cm.
Step-by-step explanation:
We have given that,
Bruce measured a buckle as 3.2 cm using the ruler
We have to find,
What is the greatest possible error?
Solution is given by,
The greatest possible error is defined as the error is half of the measuring unit.
Bruce measured a buckle as 3.2 cm using the ruler.
The measuring unit is nearest tenth of a cm or 0.1 cm.
The greatest possible error is half of 0.1.
i.e.
Therefore, The greatest possible error for the measurement 3.2 cm is 0.05 cm.
Step-by-step explanation:
The height attained by the toy as a function of time t is given by :
h is in feet and t is in seconds
Height of the toy at t = 0
Height of the toy at t = 4 seconds is :
So, between 0 to 4 seconds, height of the toy is 4 feets.
The toy's height after 0-4 seconds can be found by substituting different values of t into the given equation.
The equation given to model the toy's height is h = -2t^2 + 7t + 4, where h is the height in feet and t is the time in seconds. To find the height of the toy after 0-4 seconds, we substitute different values of t into the equation.
For t = 0, h = -2(0)^2 + 7(0) + 4 = 4 feet.
For t = 1, h = -2(1)^2 + 7(1) + 4 = 9 feet.
For t = 2, h = -2(2)^2 + 7(2) + 4 = 12 feet.
For t = 3, h = -2(3)^2 + 7(3) + 4 = 11 feet.
For t = 4, h = -2(4)^2 + 7(4) + 4 = 4 feet.

Answer:
4 hours
Step-by-step explanation:
In order to solve this problem, you need to write down the equation. The equation is 3 +8x=35. In this equation, x represents the number of hours. The coefficient is 8, and that represents the number of kilograms per hour. You subtract 3 from both sides to get 32. Next, we solve for x. Divide both sides by 8 to get x=4 hours.
Simplify the product using FOIL. (2x – 7)(5x + 5)
Answer: 10x - 25x - 35
Step-by-step explanation:
F 2x times 5x = 10x
O 2x times 5 = 10x
I -7 times 5x = -35x
L -7 times 5 = -35
Hope This Helps :)
Answer:
10x^2-25x-35
Explained:
(2x)(5x)=10x^2
(-7)(5)=-35
(-7)(5x)=-35x
(2x)(5)=10x
10x-35x=-25x
