Nathaniel purchases a one-year membership pass to an art museum. As a member, he receives a discounted entrance fee. The total c

wolverine [178]

It's a linear function with y-intercept = 12.

The slope-intercept form:

$f(x)=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

Let's read the coordinates of two points on the graph:

(2, 15) and (4, 18)

Substitute to the formula of a slope:

$m=\dfrac{18-15}{4-2}=\dfrac{3}{2}=1.5$

We have the equation of a line:

$\boxed{f(x)=1.5x+12}$

We need calculate the value of function for x = 1 and x = 20.

Substitute:

$f(1)=1.5(1)+12=13.5$

$f(20)=1.5(20)+12=30+12=42$

$12 is the "Fixed Fee", therefore the discounted entrance fee to the art museum is

$\$13.50-\$12.00=\$1.50$

The total cost is $42.00 after 20 visits.

The function y=60+25sin(pi/6)t, where t is in months and t=0 corresponds to April 15, models the average high temperature in deg

BartSMP [9]

Answer:

The maximum temperature will be of 85 degrees, on July 15.

Step-by-step explanation:

Sine function:

The sine function oscilates between -1 and 1, and it's maximum value is:

$\sin{(\frac{\pi}{2})} = 1$

y=60+25sin(pi/6)t

The maximum value will occur when $\sin{(\frac{\pi t}{6}}) = 1$ , and it will be of 60 + 25 = 85 degrees.

When will it occur?

First we find the value of t for which the value inside the function sine is $\frac{\pi}{2}$ . So

$\frac{\pi t}{6} = \frac{\pi}{2}$

$\frac{t}{6} = \frac{1}{2}$

$2t = 6$

$t = \frac{6}{2} = 3$

That is the number of months after April 15, which is 3 months. So July 15.
