Answer:

B. -\frac{7}{10} = -.7

Step-by-step explanation:

Replace all occurrences of  −  −  with a single  +. Two consecutive minus signs have the same mathematical meaning

-.75+\frac{2}{5}+.4-\frac{3}{4}

Find the common denominator.

\frac{-.75*20}{20} +\frac{2*4}{20} +\frac{.4*20}{20}-\frac{3*5}{20}

Simplify terms.

\frac{-15+8+8-15}{20}

Simplify the numerator.

\frac{-14}{20}

Reduce the expression by cancelling the common factors.

-\frac{7}{10}

<em>hope this helps, good luck :)</em>

The formula A=200e^.033t models the population of a particular city, in thousands, t years after 1998. When will the population
svetoff [14.1K]

Answer:

In the year 2010

Step-by-step explanation:

we have

A=200e^{0.033t}

where

A is the population in thousands

t is the number of years since 1998

so

For A=297 thousands

substitute and solve for t

297=200e^{0.033t}

simplify

1.485=e^{0.033t}

Apply ln both sides

ln(1.485)=ln[e^{0.033t}]

ln(1.485)=(0.033t)ln(e)

Remember that

ln(e)=1

ln(1.485)=(0.033t)

t=\frac{ln(1.485)}{0.033}

t=12\ years

1998+12=2010

In-s [12.5K]

The first rule you need to know is

(a^b)^c=a^{bc}

So, you have

\dfrac{(x^{25})^{-6}}{(x^{-3})^{48}}=\dfrac{x^{25\cdot(-6)}}{x^{-3\cdot 48}}=\dfrac{x^{-150}}{x^{-144}}

The second rule you need to know is

\dfrac{a^b}{a^c}=a^{b-c}

So, you have

\dfrac{x^{-150}}{x^{-144}}=x^{-150-(-144)}=x^{-150+144}=x^{-6}
