determine the base, b, of the exponential model. Is the base a growth or decay factor? a. b is 0.6394; It is a growth factor. b.

Kazeer [188]

An exponential model can be described by the function
$f(x) = a(b)^x$
where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.

When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.

Given the exponential model
$n=20.5(0.6394)^t$
n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.

Here, the base is 0.6394 which is less than 1, hence a decay factor.

Therefore, the base, b, of the exponential model is 0.6394; It is a decay factor.

Answer:

A: $6x^2(x^8-16)$

B: $6x^2(x^4+4)(x^2+2)(x^2-2)$

Step-by-step explanation:

A:

Our expression is $6x^{10}-96x^2$ . We need to find some common factors. Clearly, we can see that both terms share the x² part, so we can definitely take that out:

$6x^{10}-96x^2$

$x^2(6x^8-96)$

Let's see if 96 is divisible by 6:

96 ÷ 6 = 16; since there's no remainder / the remainder is 0, we know 96 is divisible by 6, so we can also factor out 6:

$x^2(6x^8-96)$

$6x^2(x^8-16)$

Thus, the answer to part A is $6x^2(x^8-16)$ .

B:

Look at the $x^8-16$ part of the above factored expression. Notice that it is a difference of squares (because $x^8=(x^4)^2$ and 16 = 4²), so we can write this as:

$x^8-16$

$(x^4+4)(x^4-4)$

Now take a look at the $(x^4-4)$ part. Again, it's a difference of squares because $x^4=(x^2)^2$ and 4 = 2², so rewrite that as:

$x^4-4$

$(x^2+2)(x^2-2)$

Put it all together:

$6x^2(x^4+4)(x^2+2)(x^2-2)$

Thus, the answer to part B is $6x^2(x^4+4)(x^2+2)(x^2-2)$ .

Answer:

sin(x) = $\frac{7}{25}$

x = 16.26°

Step-by-step explanation:

First use Pythagorean theorem to find the length of the hypotenuse. Use $a^2 + b^2 = c^2$ . Since we know a and b we can plug in to find c. When we plug in we get: $(7)^2 + (24)^2 = c^2$ . When we solve this out we get 25 = c.
