Answer:
3b-10=20
Step-by-step explanation:
3b-10=20
3b-10+10=20+10
3b=30
3b/3=30/3
b=10
Answer:
the volume is 50x1.8x2
v=180cm³
therefore, density is mass/volume
Step-by-step explanation:
mass =density x volume
mass= 7.8 x 180cm³
mass= 1,404grams
This is a parabola which looks like an inverted U. Its will have a maximum value when t = 7 as we see from the vertex form below:-
- t^2 + 14t - 40
= - ( t - 7)^2 + 49 - 40
= -(t - 7)^2 + 9
There is an axis of symmetry at x = 7.
so a is true since 7 is the maximum value of the function and its less at t = 6.
c is also true because of the symmetry about t = 7
Answer:
The minus 3 in the square will shift the graph to the right 3 x-coordinates and the minus 8 in the outside will move the graph downwards by 8 y-coordinates.
Step-by-step explanation:
The minus 3 in the square will shift the graph to the right 3 x-coordinates and the minus 8 in the outside will move the graph downwards by 8 y-coordinates.
