Mathematics

Vikentia [17]3 years ago

Answer:

B

Step-by-step explanation:

ABD (half of the rectangle) is a right-angled triangle.

so, Pythagoras applies.

c² = a² + b²

c is the Hypotenuse (the baseline opposite of the 90 degree angle) and in our case the line BD.

a and b are the 2 sides enclosing the 90 degree angle. in our case here the lines AD and AB.

so,

BD² = AD² + AB² = (6-1)² + (5-2)² = 5² + 3² = 25 + 9 = 34

BD = sqrt(34)

Which expression is equivalent to 1/3(12x+6x-21)
marin [14]

Answer:

6x-7

Step-by-step explanation:

\frac{1}{3} (12x + 6x -21)

break it into pieces

\frac{1}{3}*12x = 4x

\frac{1}{3}*6x=2x

\frac{1}{3} *-21=-7

put it all together

*since there's no negative in front  of the other numbers except 7 they're positive so you add them*

4x + 2x - 7

simplify

6x - 7

Can you help me with this please?

The half-life of the given exponential function is of 346.57 years.

<h3>What is the half-life of an exponential function?</h3>

It is the value of t when A(t) = 0.5A(0).

In this problem, the equation is:

A(t) = A(0)e^{-0.002t}.

In which t is measured in years.

Hence the half-life is found as follows:

0.5A(0) = A(0)e^{-0.002t}

e^{-0.002t} = 0.5

\ln{e^{-0.002t}} = \ln{0.5}

0.002t = -\ln{0.5}

t = -\frac{\ln{0.5}}{0.002}

t = 346.57 years.
