Answer:
-9 ≤y≤8
Step-by-step explanation:
The range is the output values or the y values for this graph
The minimum y value is -9 and the maximum is 8
-9 ≤y≤8
Y=x^2-4x+8 and 4x+y=12 so y=12-4x, insert y in the quadratic to get
12-4x=x^2-4x+8
12=x^2+8
0=x^2-4=(x-2)(x+2)
So the solutions are x=2 and x=-2.
It depends. If its the ratio of Masha to Liz, it is 10:9. If it is Liz to Masha, its 9:10. If it is Masha to the total, it is 10:19. If it is Liz to the total, it is 9:19. Hope this helps!
Answer:
The volume of the cone is 100.48 units³ approximately
Step-by-step explanation:
To find the volume of a cone with a diameter of 8 unit and height of 6 units, we will follow the steps below;
first, write down the formula for calculating the volume of a cone
v= πr²
where v is the volume of the cone
r is the radius and h is the height of the cone
from the question given, diameter d = 8 units but d=2r which implies r=d/2
r=8/2 = 4 units
Hence r= 4 units
height = 6 units
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the formula
v= πr²
v ≈ 3.14 × 4² × 6/3
v ≈ 3.14 × 16 × 2
v ≈ 100 .48 units³
Therefore the volume of the cone is 100 .48 units³ approximately
Answer:
a(n) = -3(-1/5)^(n - 1)
Step-by-step explanation:
From the first term, -3, we get the second term, 3/5, by multiplying -3 by -1/5.
Thus, the common ratio is -1/5.
The general formula in this case is a(n)=(first term)(common ratio)^(n - 1), or
a(n) = -3(-1/5)^(n - 1)
