Use the formula.

For more accurate results, repeat this process with several different circles, and then average the results.

- Three people examine the system of linear equations shown.

Makovka662 [10]

Answer:

there are no solutions as the two straight lines represented by the two equations are parallel, so they have no point in common

Step-by-step explanation:

general equation of a straight line: ax + by + c = 0

the slope (or raise) of a straight line m is equal to -a/b (b=1 a=-2 in this exercise as the equation is 1y=-2x - 4)

so m1 = -2/1 = -1/2

and m2 = -2/1 = -1/2

there is also a geometrical explanation, but I am not sure if it could be too complex

Using technology, we determined that Mary’s investment account can be modeled by the function, M(x) = 4.96(2.18)x in thousands o

leonid [27]

Well, her initial investment happened at day 0, namely x = 0, let's check,

$\bf M(x)= 4.96(2.18)^x\qquad \boxed{x=0}\qquad M(0)= 4.96(2.18)^0
\\\\\\
M(0)= 4.96(1)\implies M(0)=4.96$

ikadub [295]

Answer:

the answer is D

Step-by-step explanation:

Think of the Pythagorean Theorem which states that a^2 + b^2 = c^2. The Pythagorean Identities used in trigonometry are the angle version which can be used to simplify expressions.
