Answer:
2TTr3/ 3.14 if you remember the is half a diameter in side of the hemisphere coming from a 7th grader
Step-by-step explanation:
Answer:
0.3
Step-by-step explanation:
Answer:
b. 256
Step-by-step explanation:
Data:
W= 8
L= 8
H= 8
soln:
firstly the formula of lateral area is
LSA = (2W+2L) H
therefore:
LSA = (2×8+2×8) 8
LSA = (16+16) 8
LSA = (32) 8
LSA = 256
Fist u have to calculate how much it takes to reach the certain number for instance it takes 30 per gallon because 30 times 1 is 30. 30 times 2 is 60 and so on
Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.
<h3>
What can we say about the discriminant?</h3>
For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
- If D = 0, there is only one real zero.
- If D > 0, there are two real zeros.
- If D < 0, there are two complex zeros.
In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.
