Answer:
Step-by-step explanation:
The answer would be .17 because you move the decimal to the left two times.
For this case, we can use the Intersecting Chord Theorem.
The theorem states that QA * AS is always equal to TA * AR.
Therefore we can write it as:
9 * 4x = 12 * (x + 2)
Performing the operations:
36x = 12x + 24
24x = 24
x=1
Calculating the length of chords QS and TR:
QS = 9 + 4x = 9 + 4 = 13
TR = 12 + (x+2) = 12 + 3 = 15
Therefore the length of the shorter chord is 13.
Answer:
6 in
Step-by-step explanation:
To find the height, just divide the volume by the base area
First find the slope of the line connecting these two points:
6-5
m = ------------ = -1/2
-4+2
Substitute this slope into y = mx + b: y = (-1/2)x + b.
Next, subst. 5 for y and -2 for x, and find b:
5 = (-1/2)(-2) + b, or 5-1=b. Then b = 4, and
the equation of the line is y = (-1/2)x + 4.
