Enrollment in a dance studio has grown exponentially since the studio opened. A graph depicting this growth is shown. Determine
denis23 [38]

Answer:

Option (4). 25%

Step-by-step explanation:

The graph attached shows the exponential growth.

Let the graphed function is y = (1+\frac{r}{100})^{t}

Here 'r' = Rate of growth

t = Duration of time in years

y = enrollments after time 't' years

Graph shows at time 't' = 0 or initially number of enrollments = 20

After 8 years number of enrollments will be

120 = 20(1+\frac{r}{100})^{8}

\frac{120}{20}=(1+\frac{r}{100})^{8}

6 = (1+\frac{r}{100})^{8}

log 6 = 8\text{log}(1+\frac{r}{100})

0.77815 = 8\text{log}(1+\frac{r}{100})

\text{log}(1+\frac{r}{100}) = 0.0972689

(1+\frac{r}{100})=1.251

\frac{r}{100}=0.251

r = 25.1%

r ≈ 25%

Therefore, Option (4) will be the answer.

Lostsunrise [7]

Answer:

y= -1

Step-by-step explanation:

(2) (0) − y = 1

0 + − y = 1

(−y) + (0) = 1

−y = 1

Step 2: Divide both sides by -1

Y = −1
