Answer:
The sum is 
.
Step-by-step explanation:
Consider the provided information.
The given expression are - 10t and t - 10t
We need to find the sum of the opposite of -10 t and t - 10t.
The opposite of -10 t is 10 t.
Remove the parenthesis.
Simplify the number
Use Additive inverse.
Hence, the sum is .
Answer:
4 root 5
Step-by-step explanation:
assume / to be root sign
/10 x /8
simply both roots so that one of numbers is a square number
/10= /2 x /5
/8= /2 x /4
so
/4=2 and /2 x /2= 2
2×2=4 and you have /5 left over so
4/5
hope this helps!
To determine the maximum value of a quadratic function opening downwards, we are going to find the vertex; then the y-value of the vertex will be our maximum.
To find the vertex (h,k) (where h=x-coordinate and k=y-coordinate) of a quadratic function of the form
we'll use the vertex formula:
, and then we are going to replace that value in our original function to find k.
So, in our function
,
and
.
Lets replace those values in our vertex formula:
Now that we know the x-coordinate of our vertex, lets replace it in the original function, to get the y-coordinate:
We just prove that the vertex of
is (2,1), and for the graph we can tell that the vertex of
is (-2,4). The only thing left is compare their y-coordinates to determine w<span>hich one has the greater maximum value. Since 4>1, we can conclude that </span>
has the greater maximum.
