Answer:

s = - 18

Step-by-step explanation:

15 + 26s - 6 = - 9 + 25s

9 + 26s = - 9 + 25s

18 = - s

s = - 18

kakasveta [241]

Answer:

Step-by-step explanation:

length times width = area

so you have 8.5w=93.5

divide 8.5 on both sides to get your answer

w= 11

so your width must be 11 inches

What are the coordinates of the point on the directed line segment from (-6,9) to

brilliants [131]

Answer:

Step-by-step explanation:

difference of x-coordinates = 4-(-6) = 10

difference of y-coordinates = -1-9 = -10

partition the differences into a ratio of 1:4

10 × 1/(1+4) = 2

-10 × 1/(1+4) = -2

(-6+2,9-2) = (-4,7)

12/16 - 7/18 in simplest form

Ivan

Answer:

The answer is $\frac{13}{36}$

Step-by-step explanation:

The formula is:

$\frac{a}{b} - \frac{c}{d} = \frac{ad - bc}{bd}$

In this case :

$\frac{12}{16} - \frac{7}{18} = \frac{12 x 18 - 16x17}{16x18} = \frac{216 -112 }{288} = \frac{104}{288}$

To get the simples form notice both 104 and 288 are divisible by 8 and 104/8 = 13 and 288/8 = 36.

Thus $\frac{104}{288} = \frac{13}{36}$

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.
