Where is the vertex of y=3(x-26)^2+14?

Morgarella [4.7K]

The vertex is (26,14)

Because it’s written in vertex form which y=a(x-h)^2 + k. H is the x for the vertex And h is changed to it’s opposite. So since 26 is negative it would actually be positive 26. While k ls the y of the vertex which is 14 in our case

The distance d (in inches) that a ladybug travels over time t(in seconds) is given by the function d (1) = t^3 - 2t + 2. Findthe

mrs_skeptik [129]

The Solution:

Given that the distance is defined by the function below:

$d(t)=t^3-2t+2$

We are required to find the average speed of the ladybug from t=1 second to t=3 seconds in inches/second.

Step 1:

For t=1 second, the distance in inches is

$d(1)=1^3-2(1)+2=1-2+2=1\text{ inch}$

For t=3 seconds, the distance in inches is

$d(3)=3^3-2(3)+2=27-6+2=21+2=23\text{ inches}$

By formula,

$\text{ Average Speed=}\frac{\text{ distance covered}}{\text{ time taken}}$

In this case,

Distance covered = change in distance, which is

$\text{ change in distance=d(3)-d(1)=23-1=22 inches}$

Time taken = change in time, which is:

$\text{ Change in time=t}_2-t_1=3-1=2\text{ seconds}$

Substituting these values in the formula, we get

$\text{ Average Speed=}\frac{22}{2}=11\text{ inches/second}$

Therefore, the correct answer is 11 inches/second.
