If you are just supposed to evaluate the a) f(0) and b) f(4) then you would just plug it in the equation.
f(0)=0^2 - 8*0 + 16
f(0)=0 - 0 + 16
f(0)=16
f(4)=4^2 - 8*4 +16
f(4)=16 - 32 + 16
f(4)=0

The answer is R=0.053707443....
Round to the nearest decimal place as it asks for
i hope this helps :)
Answer:
C.

.
Step-by-step explanation:
Let r represent the cost of one packet of radish seeds and let t represent the cost of one packet of tomato seeds.
Roman spent $62.75
This implies that,

Roman bought 32 packets of seeds and one packet of radish seeds costs
$ 1.75.
One packet of tomato seeds costs $ 2.50.
This implies that,

Using guess and check means we substitute into the given equation.
A) We substitute

into both equations.



Both equations are not satisfied.
B)
We substitute

into both equations.



Both equations are not satisfied.
C)
We substitute

into both equations.



Both equations are satisfied.
Hence the solution is,

D) We substitute

into both equations.



Both equations are not satisfied.
For the cut glass pieces to be rectangular in shape, the glass cutter should ensure:
- All four interior angles = 90° each.
- Opposite sides are parallel and equal to each other.
- Diagonals should be of the same length and should bisect each other.
<h3>Properties of a Rectangle</h3>
- All four angles of a rectangle are 90° each.
- There are two pairs of parallel sides that are equal in length.
- The diagonals bisect each other and are of equal length.
Thus, to ensure the cut glass pieces are rectangular in shape, he should ensure the following:
- Make the four interior angles 90° each.
- The opposite sides should be parallel and equal to each other.
- The diagonals should be of the same length and should bisect each other.

Answer:
1. 16π
2. 112π
3. 351.68
Step-by-step explanation:
Area of a circle = πr^2
Substitute...
=4^2π
=16π
To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...
16π*7=122π
You then just subsitute π by 3.14 so...
122(3.14)=351.68
