Answer: domain = 12 students
Range = $60
Step-by-step explanation:
Given that the total dollar amount earned, E. Is a function of the number of members who perform communityservice, n
That is
E(n) = 5n
Since the club earn $5 on each student who does community service,
Domain is independent variable n
While range is dependent variable E
Domain is therefore = 12 students
Range = 12 × 5 = $60
Please see the attached figure. This is how you draw a hyperbola. Its general formula is:
(x-h)²/a² - (y-k)²/b² = 1, where
(h,k) is the center
a is the semi-major axis
b is the semi-minor axis
The given equation is
(x+4)²/16 - (y+3)²/25 = 1
So, from the general form we can deduce that,
Center(-4,-3)
a = 4
b = 5
So, the first point we can plot is the centerpoint. Next, you draw the two intersecting lines. Their slopes are +/- b/a. Thus, it corresponds to +/- 5/4. Using this slope, we can find the equation of the two lines by using the slope and the center.
-3 = +5/4 (-4) + b ---> b= 2
-3 = -5/4 (-4) + b ---> b= -8
So, you plot the equations y=5/4x + 2 and y = -5/4 x -8 by assigning values of x and plotting them against y. Then, the vertex of the hyperbolas are 4 units from the center, denoted by the green dots. The hyperbola is shown in the next picture.
The answer is (2)....................................
Two equations
W*L=1260
3W+48=L
Solve
L=1260/W
3W+48=1260/W
3W^2+48W=1260
3W^2+48W-1260=0
Divide by 3
W^2+16W-420=0
Factor
(W-14) (W+30)
W=14
L=90
Answer:
