Answer:
The 8 should have remained positive.
Step-by-step explanation:
8-(-2)=8+2=10
Two negatives make a positive so 8-(-2) will turn into 8+2.
Laura was wrong because she thought the 8 turned to a negative but that makes no sense.
The tangents are equal length, so
.. 8x = x^2
We presume their length is not zero, so we can divide by x to get
.. 8 = 2x
.. 4 = x
Then the length of each tangent is 8*4 = 32 units.
Answer:
21
Step-by-step explanation:
Remember that the centroid splits the 3 medians of a triangle into a ratio of 1:2
Since TS < TN, TS = 42/2 = 21
Answer:
the formula represent the correct way is π(4)^2 (5)
Step-by-step explanation:
The formula that represent the correct way to calculate is given below:
As we know that
Volume = πr^2 h
where
r denotes the radius i.e. 4 inches
And, h denotes the height i.e. 5 inches
Now placed these values to the above formula
So,
= π(4)^2 × 5
= 80π in^3
Hence, the formula represent the correct way is π(4)^2 (5)
