Answer:
We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.
In scientific notation, just move the decimal point over however many numbers are in the power.
In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030
The altitude will be the geometric mean of the lengths, so
. The smaller leg is the hypotenuse of a right triangle sides 4 and
so the usual trig cliche, hypotenuse 8.
Answer: 8
Answer:
70
Step-by-step explanation:
Using the similarity theorem;
AB/BC = AD/AB
x/7+3 = 7/x
x/10 = 7/x
x^2 = 70
x = √70
Hence the required value inside square root is 70
