The correct answer is Choice A.

The amount of money is decreasing at a rate of 13% per year. The rate that is shown in the equation is 0.87 or 87%. 87% is 13% lower than 100%. That is the amount of the decrease each time.

Rewrite the following without an exponent. 6^-2<br> Please answer ASAP!
julia-pushkina [17]

Answer:

Rewriting 6^{-2} without an exponent we get \mathbf{\frac{1}{36}}

Step-by-step explanation:

We need to rewrite the following without an exponent. 6^{-2}

We need to solve the exponent to find the result.

We know the exponent rule: a^{-b}=\frac{1}{a^b}

Now using this rule to solve the equation:

6^{-2}\\=\frac{1}{6^2}\\We \:know \:that\:6^2 = 6\times 6=36\\=\frac{1}{36}

So, Rewriting 6^{-2} without an exponent we get \mathbf{\frac{1}{36}}

What is this can anyone help me
Solnce55 [7]

g(x) = (x - 3)² - 4

given f(x) is shifted a units horizontally to the right → f(x) → f(x - a)

If f(x) is shifted by a units horizontally left → f(x) → f(x + a)

If f(x) is shifted by b units vertically up → f(x) → f(x) + b

If f(x) is shifted by b units vertically down → f(x) → f(x) - b

The vertex (0, 0) of f(x) has shifted to (3, -4)

that is 3 units horizontally to the right and 4 units vertically down

hence g(x) = (x - 3)² - 4
