Answer:

4.69 inches

Step-by-step explanation:

sin = opposite/hypotenuse

sin 23 = a/12

To solve for a, multiply both side by 12, so a is by itself.

12 · sin23 = a/12 · 12

12 · sin23 = a

use your calculator to find the sin of 23, which is approximately 0.390731128

Multiply by 12

0.390731128 * 12 = 4.688

Answer:

Step-by-step explanation:

x^2 -8x +3 = 0

(x^2 - 8x + 16) = -3 + 16

(x-4)^2 = 13

x - 4 = (+/-)sqrt(13)

x = 4 +/- sqrt(13)

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.

From the second:

x=(4+y)/2 and applying this to first:

4+y+3y=12

4y+4=12

4y=8

y=2 and since x=(4+y)/2, x=3 so

x+y=2+3=5
