Answer:
260 nesting turtles were at this sanctuary last year
Step-by-step explanation:
Given:
The number of nesting turtles decreased = 10%
Number of turtles present in sanctuary this year = 234
To Find:
Number of nesting turtles present at this sanctuary last year= ?
Solution:
Let the number of nesting turtles present at this sanctuary last year be x
Then,
x- 10% of x = Number of turtles present in sanctuary this year
x- 10% of x = 234
x= 260
9514 1404 393
Answer:
3
Step-by-step explanation:
The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-2))/(3 -1) = 6/2
m = 3
The average rate of change on the interval is 3.
Answer:
If A is wrong then B I think
Step-by-step explanation:
I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.
My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
bearing in mind that "a" is the length of the traverse axis, and "c" is the distance from the center to either foci.
we know the center is at (0,0), we know there's a vertex at (-48,0), from the origin to -48, that's 48 units flat, meaning, the hyperbola is a horizontal one running over the x-axis whose a = 48.
we also know there's a focus point at (50,0), that's 50 units from the center, namely c = 50.
