Answer:
TU = 2.5
Step-by-step explanation:
sin 34 = 1.4/TU
0.5592 = 1.4/TU
TU = 2.5
Answer:
6 2 points, 2 3 points
Step-by-step explanation:
x = 2point shots, y=3 point shots
total points: 2x +3y=18
total made: x+y=8
x= 8-y, derived from isolating x in total made equation
plug into equation 1
2(8-y) + 3y =18
-2y+16+3y= 18
y +16 = 18
y = 2
x = 8-2 = 6
6 2 points, 2 3 points
Answer:
m-1-n
Step-by-step explanation:
Answer:
a) independent = hours
dependent = wages
b ) W = 10 + 5h
c)27.50
Step-by-step explanation:
The independent variable is the one that you change which is the number of hours that it takes
The dependent variable is the variable that changes based on the independent variable. The wages depends on the hour worked so the wages are the independent variable
The wages equal the fixed cost plus the hourly rate times the number of hours where W is the wages and h is the number of hours
W = 10 + 5h
W = 10 + 5( 3.5)
= 10 + 17.5
= 27.5
Answer:
y = (-7/3)(x - 9)
Step-by-step explanation:
<em><u>(12, - 7)</u></em>
y = a(x - h)^2
-7 = a(12 - h)^2
- 7 = a(144 - 24x + h^2)
<em><u>(9,0)</u></em>
0 = a(x - h)^2
0 = a(9 - h)^2
0 = a(81 - 18h + h^2)
From (9,0) we can conclude that
a = 0
or
(9 - h)^2 = 0
Let's try the second possibility.
Take the square root of both sides.
9 - h = sqrt(0)
Add h to both sides
9 - h = 0
h = 9
So now what we have is
y = a(x - 9)
Use the first equation to get a
-7 = a(12 - 9)
-7 = a(3)
-7/3 = a
Answer
y = (-7/3)(x - 9)
