Answer:
100 feet below sea level
Step-by-step explanation:
Our function is
This is written in vertex form,
f(x) = a(x-h)²+k,
where (h, k) is the vertex of the function.
The vertex of a function is either the maximum or the minimum value of a quadratic function.
For our function, the value in place of h is 60 and the value in place of k is -100; this makes the vertex
(60, -100).
This means at 60 seconds, the diver will reach a minimum of -100 feet, or 100 feet below sea level.
Answer: 61 is NOT a solution. The first thing I did was replace the variable (x) with 61, afterwards I rewrote the equation as 61+ 23= 82, if you add 61 by 23 you'll get 84! 84>82, which proves 61 is not a solution!
Step-by-step explanation:
Answer:
The shape is the same
Step-by-step explanation:
we know that
A dilation is a non rigid transformation, that change the size but not the shape of the original figure
so
If the dilation scale factor is 4, the figure size increases by 4, but the shape remains the same
