Answer:

11 \frac{3}{4} min

Step-by-step explanation:

In order to solve this problem, we must subtract the times he has already used from the time he has available, so we get:

30-11 \frac{3}{4} - 6 \frac{1}{2}

we can start solving this subtraction by turning all of the numbers into improper fractions so we get:

\frac{30}{1}-\frac{11*4+3}{4}- \frac{6*2+1}{2}

\frac{30}{1}-\frac{47}{4}- \frac{13}{2}

next, we can find a least common denominator. In this case it will be 4, so we need to turn all denominators into a 4, so we get:

\frac{30*4}{1*4}-\frac{47}{4}- \frac{13*2}{2*2}

\frac{120}{4}-\frac{47}{4}- \frac{26}{4}

and now we can subtract the numerators and copy the denominators so we get:

\frac{120-47-26}{4}

\frac{47}{4}

which can now be turned into a mixed number by dividing 47/4 which yields 11 with a remainder of 3, so the mixed number is:

11 \frac{3}{4} min

and this is the amount of time he has available to solve the las problem.

How does the graph of g(x) = (x − 2)3 + 6 compare to the parent function of f(x) = x3?
Svet_ta [14]

The graph of g(x) is the graph of f(x) translated 2 units to the right and 6 units up.

<h3>How does the graph of g(x) compare to the one of f(x)?</h3>

Here we have:

f(x) = x^3\\\\g(x) = (x - 2)^3 + 6

You can notice that if we take f(x), and we shift it 2 units to the right, we have:

g(x) = f(x - 2)

Then if we apply a shift upwards of 6 units, then we have:

g(x) = f(x - 2) + 3

Replacing f(x) by the cubic parent function, we have:

g(x) = (x - 2)^3 + 6

So we conclude that the graph of g(x) is the graph of f(x) translated 2 units to the right and 6 units up.

pav-90 [236]

Answer:

5 units above the dotted line

Step-by-step explanation:

The reason for this is that there is a distance of 5 units between point B and the line so we know that when it is reflected there will be a distance of 5 as well.
