The answer is 10 because m^-2 equals -2*-2.Which equals 4 and then 7*-2 equals-14.So 4- -14 equals 18.Then 18-8 equals 10.

$(-2)^{2}$ is 4.

Then, 7(-2) is -14.

Then, 4 - (-14) is (-18).

Finnaly, (-18) - 8 is [-26]

The total cost of a new automobile, including a 5% sales tax on the price of the automobile, is $ 26,708. How much of the tot

RideAnS [48]

Let's say the price without tax of the car is "x", then you add 5% of "x" and it becomes $26,708.

now, if we take "x" to be the 100% of the price, and then adding a 5% of "x" will simply give us a 100 + 5 = 105%, and that's what 26,708 is, thus, 26,708 is the 105%, and if "x" is the 100%, what is "x" anyway?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
26708&105
\end{array}\implies \cfrac{x}{26708}=\cfrac{100}{105}\implies x=\cfrac{26708\cdot 100}{105}$

A population of beetles is modeled by the equation b(t) = 3,000 (2)t where t represents the number of weeks since the population

Liula [17]

Answer:

See Explanation

Step-by-step explanation:

Given

$b(t) = 3000 * 2^t$

The question is incomplete;

A possible question could be to calculate the initial amount of beetle

An exponential function is represented as:

$f(x) = ab^x$

Where

$a \to Initial\ amount$

By comparison:

$a = 3000$ --- The initial number of beetles

Another question could be to solve for f(t), after a certain number of weeks (say 3)

Substitute 3 for t in: $b(t) = 3000 * 2^t$

$b(3) = 3000 * 2^3$

$b(3) = 3000 * 8$

$b(3) = 24000$

On the map of an amusement park on a coordinate grid, the skating rink is at (−1.5, −1).

inessss [21]

The first option is correct.

Moving 1.5 units to the left (or -1.5 units to the right).
Moving 1 unit down (or -1 unit up).

Therefore you get the result of (-1.5, 1) as is the location of the rink.
