Your class is learning to tie knots. Each student needs a piece of rope that is 3/8 yard long. How many yards of rope are needed for the 16 students in your class?
Answers
Answer:
6 yards
Step-by-step explanation:
Given that one class is learning to tie knots
There are 16 students in the class.
Each student has to have a separate piece of rope to learn to tie knots.
Length of the piece of rope needed for each child = 3/8 yars
Hence total length required for all the 16 students would be
a direction variation question
So we multiply 16 by 3/8 to get
answer.
Answer = 16(3/8) = 6 yards

-The axis of symmetry is x = -1/2
-The domain is all real numbers.
-The range is all real numbers.
-The x-intercepts are at (−2, 0) and (1,0).
-The function is decreasing from (−∞, 6.75)

f(-1) = -3(-1)^2 - 3(-1) + 6 = -3(1) - (-3) + 6 = -3 + 3 + 6 = 6
f(-0.5) = -3(-0.5)^2 - 3(-0.5) + 6 = -3(0.25) - (-1.5) + 6 = -0.75 + 1.5 + 6 = 6.75
f(0) = -3(0)^2 - 3(0) + 6 = 0 + 0 + 6 = 6
From the above, the graph stopped increasing at x = -0.5 and started decreasing. Hence, the axis of symmetry is x = -1/2
The domain of all quadatic expression is all real numbers because there is no value of x for which f(x) does not exist.
The range is NOT all real numbers because for instance, there is no value of x for which f(x) = 7.
f(-2) = -3(-2)^2 - 3(-2) + 6 = -3(4) - (-6) + 6 = -12 + 6 + 6 = 0
f(1) = -3(1)^2 - 3(1) + 6 = -3(1) - 3 + 6 = -3 + 3 = 0
Hence, the x-intecepts are at (-2, 0) and (1, 0)
The function is INCREASING from (−∞, 6.75)

Answer:
degrees Celsius.
Step-by-step explanation:
Let x represent number of kilometers.
We have been given that the temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. So temperature decreased in x hours would be .
The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature at an altitude of x kilometers would be .
To find temperature outside a plane flying at an altitude of 5 kilometers, we will substitute in our expression as:
Therefore, the temperature outside a plane flying at an altitude of 5 kilometers would be degrees Celsius.
6.8 times 5 is 34
since 34 is bigger than 12, you take 12 from 34 and add a negative sign, and that would be -22.
You can use a calculator if u want and is allowed too. :)
