Answer:
<h2>5</h2>
Step-by-step explanation:
Given the expression f(z) = 9-z
To get the value of the resulting value of the function when z = 4, all we need to do is substitute the value of z given into the function to have;
f(4) = 9-4
f(4) = 5
The right answer is 5
Answer:

Step-by-step explanation:
Let us consider the equation 
For a quadratic equation in a standard form,
, the axis of symmetry is the vertical line
.
Here in this case we have, 
Putting the values we get,

We can see that the axis of symmetry is x=3 and the graph is giving minimum at x=3.
Therefore, the required equation is
. Refer the image attached.
Step-by-step explanation:
0.000672, 6.72×10⁵, 67.2×10‐⁴, 672×10⁴
Answer:
Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.
Step-by-step explanation:
There are 6 plates which consist of 25 lb plates and 5 lb plates.
We need to figure out how many of each one compose 110 lb.
Thus, 25 x 4 = 100... 4 plates of 25 pounds.
5 x 2 = 10 ... 2 plates of 5 lbs.
100+10= 110, which is our goal! And a total of 6 plates were used!
All things put into great consideration, Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.
I hope this helped!
