Answer
25 square
centimeters
Step-by-step explanation:
We want to find the area of the image of a rectangle with an area of 25 square
centimeters that has been rotated and reflected in
the coordinate plane.
Recall that, rotation and reflection are rigid transformations.
This means that, the preimage and the image rectangle are congruent.
Therefore the area of the image rectangle is still 25 square centimeters
All square sides are equal so 20 x 20 is 400 and to get the area of a circle is pi x radius squared so the answer is C
Answer:
Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:
We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:
Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side
and we simplify:
now it's easy to solve for t:
And thus we arrive to the solution.
