Marcel made an error when he used the distributive property to write an equivalent

natima [27]

Answer: Upper left corner

Explanation:

The error happens in step 2. Notice that x is <u>not</u> part of the second term 16, so there's no way to factor x from it unless you want a fraction to result.

The second step should be 8(4x-2)

Another way to factor is to say 16(2x-1)

Use the function below to find F(2).<br> F(t) = 2•1/2^3t

navik [9.2K]

Answer:

$F(2)= \frac{1}{32}$

Step-by-step explanation:

The given function is

$F(t) = 2 \cdot \: \frac{1}{{2}^{3t} }$

To find F(2), we substitute t=2 into the function.

This means that wherever we see t, we put 2

$F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} }$

We multiply the exponent in the denominator to get:

$F(2) = 2 \cdot \: \frac{1}{{2}^{6} }$

We evaluate to get:

$F(2) = 2 \cdot \: \frac{1}{64}$

We now cancel the common factors to get:

$F(2) = \frac{1}{32}$

What is the standard form of the equation of the circle?

lisabon 2012 [21]

The standard form of the equation of a circle is:
$(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}$
Where the point (a,b) represents the centre and r is the radius. So, given your information, the equation will be:
${(x + 4)}^{2} + {(y + 3)}^{2} = 25$
