Answer:
7
Step-by-step explanation:
Going from -5 to 2 we get
1) -4
2) -3
3) -2
4) -1
5) 0
6) 1
7) 2
So, in total, there are 7 numbers between -5 and 2
Standard form of the parabola function: (y-k) = a(x-h)²
vertex (h,k)==> vertex (2,-5) [given]. Now plug==> y+5 =a(x-2)²
To calculate a, plug in the equation the coordinates of A(3,4)
4+5 = a(3-2)² ==> 9=a
Finally the equation is f(x) = y+5 = 9(x-2) or y = 9(x-2)² -5
Or f(x) =y = 9x² - 36x + 3
Answer:
D. 203
Step-by-step explanation:
volume= width X height X length
volume= 8 X 7 1/4 X 3 1/2
volume= 203
Answer:
45, 48, and 51.
Step-by-step explanation:
The numbers are 3x, 3x+3, and 3x+6. Write the equation: 9x+9=6x+54. Solve: x=15. So the numbers are 45, 48, and 51.
Check: 45+48+51 is 144. 45*2+54=144. 144=144 Correct!
