Answer:
a. 10
Step-by-step explanation:
x is the radius and any line drawn from centre of the circle to the ends of circle is radius.
using pythagoras theorem:
base^2+height^2= Hypotenuse^2 (over here hypotenuse is radius)
6^2+8^2=x^2
36+64=x^2
100=x^2
x= root of(100)
x=10
Answer:
5x² - 35x + 50
Step-by-step explanation:
distribute 5 to (x-2) to get:
5x-10
now multiply (5x-10) and (x-5) to get:
5x² - 25x - 10x + 50
combine like terms to get:
5x² - 35x + 50
Answer:
To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents. In either case, the answer must be converted to scientific notation.
