Answer:
| 157 +/- 145 |
Step-by-step explanation:
302-12 = 290 total range
290/2 = 145 absolute value range
| 157 +/- 145 |
The two answers to that are 12 and 301
Answer:B
Step-by-step explanation:
3x200= 600
1000-600=400
400 divided by 5 = 80
answer is 80 adults

Answer:
The vertex is (2,1)
Step-by-step explanation:
ƒ(x) = –x^2 + 4x – 3
Factor out the negative
= -(x^2 -4x+3)
Factor
What 2 numbers multiply to +3 and add to -4
-3*-1 = 3
-3+-1 = -4
f(x) = -( x-3)(x-1)
Find the zeros
0 = -( x-3)(x-1)
0 = x-3 0 = x-1
x=3 x=1
The x value of the vertex is 1/2 way between the two zeros
(3+1)/2 = 4/2 =2
To find the y value, substitute x=2 in
f(2) = -( 2-3)(2-1)
=-(-1)(1) = 1
The vertex is (2,1)
3.2 is the Length of y 7.5 is the length of z and the length of x is 12.5
