Cross section is the area you make when you make a cut across a shape. In this case, the cut must be parallel to the base. Hence, the cut shape would be same to that of the base. The base's dimensions are 7 cm long x 5 cm wide. Thus, the cross section area is 35 square centimeters.
Let the three integers be x - 2, x and x + 2, then
x - 2 + x = 4(x + 2) - 24
2x - 2 = 4x + 8 - 24
4x - 2x = -2 + 16
2x = 14
x = 7
Therefore, the integers are 5, 7 and 9
y= x^2 - 6x-7
Vertex = -b /2a
b= -6
a= 1
-(-6)/2(1)= 3
x= 3
Use the substitution method to find y
y= (3)^2-6(3)-7
(3)(3)-18-7
9-25
y= -16
Vertex is (3, 16)
Find x- intercept (y= 0)
y= x^2 - 6x-7
(x-7)(x+1)
x-7= 0
Move -7 to the other side. Sign changes from -7 to 7
x-7+7= 0+7
x= 7
x+1= 0
Move +1 to the other side. Sign changes from +1 to -1
x+1-1= 0-1
x= -1
Answer :B. Vertex: (3, -16); Intercepts: x=-1,7
Answer:
Hi there here is the answer!
Step-by-step explanation:
Out of the 3 main chioces there is a total of 15!
so, it would be a probability of <em>5/15. or 1/3 / 1:3</em>
