Gina says that she can find the length of the diagonal, c, of the rectangular prism by using the Pythagorean theorem twice.
1 answer:
Answer:
However, that's the length of "c" and you're looking to drag it in. So,o you drag in 10^2+7^2=a^2.
Then, as shown by the first picture attatched, you can drag in the one with "c" and "a" with the five shown.
Step-by-step explanation:
To find "c" the diagonal, as explained, you need to use the theorem twice. You can first use it by finding "a", as you already have "b". To find a, you do 10^2+7^2=a^2, the hypotenuse.
100+49=149.
So, a is root 149.
a^2+b^2=c^2 so
149+25=174

Answer:
The equation the circle is given by
Step-by-step explanation:
The general form of the circle is
Given points are (5,0) , (0,4) and (2,4)
Let the points (5,0) , (0,4) and (2,4) be (x_1,y_1) , (x_2,y_2) and (x_3,y_3) respectively
The equation of the circle passes through given points (5,0) , (0,4) and (2,4)
Substituting the point (5,0) in (1)
Substituting the point (0,4) in
Substituting the point (2,4) in
By solving the equations (2) ,(3) and(4) we get the values of D,E and F as below
,
and
substituting the values of D,E and F in (1) we get
Now multiplying the above equation into 4 we get
