Answer:

\boxed{\bold{\frac{n^3}{m^2}}}

Step By Step Explanation:

  • Apply Exponent Rule \bold{\:a^{-b}=\frac{1}{a^b}}

\bold{m^{-2}=\frac{1}{m^2}}

\bold{n^3\frac{1}{m^2}}

  • Multiply Fractions \bold{\:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}}

\bold{\frac{1\cdot \:n^3}{m^2}}

  • Multiply: \bold{1\cdot \:n^3=n^3}

\bold{\frac{n^3}{m^2}}

\boxed{\bold{Mordancy}}

Ms. Hawkinson is planning to take more pictures of her students. She bought 8 rolls of film and 2 camera batteries for $23.00. T
charle [14.2K]

Answer:

1 Roll = $2.50

1 Battery = $1.50

Step-by-step explanation:

From the question we know that,

8 Rolls + 2 Batteries = $23, and

6 Rolls + 2 Batteries = $18

We can subtract the two equations to obtain a third equation,

(8 Rolls + 2 Batteries) - (6 Rolls + 2 Batteries) = $23 - $18

(8 - 6) Rolls + (2 - 2) Batteries = $23 - $18

2 Rolls = $5

Divide RHS and LHS by 2, to obtain the cost of a roll,

2 Rolls / 2 = $5 / 2

1 Roll = $2.50

If one roll costs $2.50 then 6 rolls cost $15,

6 x $2.50 = $15

We plug in this value into the second equation,

$15 + 2 Batteries = $18

Subtract both sides by $15,

$15 + 2 Batteries - $15 = $18 - $15

2 Batteries = $3

Divide RHS and LHS by 2 to obtain the final answer,

2 Batteries / 2 = $3 / 2

1 Battery = $1.50

Suppose h(t) = -4t^2+ 11t + 3 is the height of a diver above the water (in
Bingel [31]
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
