Answer:

a = 5120

b = 1.25

Step-by-step explanation:

Let the exponential function representing the given table is,

f(x) = a(b)^x

Here, f(x) = Number of views

x = Number of weeks

We choose two points from the given table and satisfy the equation of the function.

Let the points are (0, 5120) and (1, 6400)

For a point (0, 5120),

f(0) = a(b)⁰ = 5120

a = 5120

Now for the second point (1, 6400),

6400 = 5120(b)¹

b = \frac{6400}{5120}

b = 1.25

Therefore, a = 5120 and b = 1.25 are the values.

How can you check to see if two ratios form a proportion? Explain the method you used to find the answer to the previous problem
antiseptic1488 [7]

Answer:

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Which expression is equivalent to StartFraction b Superscript negative 2 Baseline Over a b Superscript negative 3 Baseline EndFr
nignag [31]

Answer:

  • \frac{b^{-2}}{ab^{-3}}=\frac{b}{a}

Step-by-step explanation:

Writing the description in algebraic translation

\frac{b^{-2}}{ab^{-3}}

so we have to find the expression which will be equal to \frac{b^{-2}}{ab^{-3}}.

Considering the expression

\frac{b^{-2}}{ab^{-3}}

\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

\frac{b^{-2}}{b^{-3}}=b^{-2-\left(-3\right)}

so the expression becomes

=\frac{b^{-2-\left(-3\right)}}{a}            ∵ \frac{b^{-2}}{b^{-3}}=b^{-2-\left(-3\right)}

\mathrm{Subtract\:the\:numbers:}\:-2-\left(-3\right)=1

=\frac{b}{a}

Therefore,

                    \frac{b^{-2}}{ab^{-3}}=\frac{b}{a}
