Hello from MrBillDoesMath!

Answer:

Parabola

Discussion:

The equation is x = (1/16) y^2. Multiply both sides by 16 to get

y^2 = 16x is a parabola that "opens to the right". (Looks like y = x^2 rotated clockwise 90 degrees)

Thank you,

MrB

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.

Please me answer this question

Alex73 [517]

Answer:

x=11, y=13

Step-by-step explanation:

3x-2y=7

3x-2(x+2)=7 . - x + = - -2*+2=-4

3x-2x-4=7

1x-4=7

x=7+4

x=11

y=x+2

y=11+2

y=13
