Answer:
See below.
Step-by-step explanation:
These are the x intercepts so the value of the function at these 2 points is 0.
The equation is a(x -1)(x + 7) = 0. If we solve this for x we get x = 1 and x = -7.
The constant a can be any value except 0. There are many equations because of this. If a = 1 the equation is (x - 1)(x + 7) = 0.
Its an ellipse.
3 (x+7)^2+2 (y-2)^2-6 = 0
So right now it is telling you that out of 60 books, 24 are nonfiction. Therefore that is 24/60. 40% of 60 is 24 so that means the other 60% is nonfiction. Hope this isn't confusing and it helps.
Answer: No
Step-by-step explanation:
To find out if it is a right triangle then use the formula a^2 + b^2 = c^2 where a and b are the legs which are the two small sides and c is the hypotenuse the longest side. Input the values for a, b, and c and solve.
a = 12
b = 16
c= 25
12^2 + 16^2 = 25^2
144 + 256 = 625
400 = 625
This means that it is not a right angle because 400 does not equal to 625.
