which equation describes the motion of the train?
d=50t
d=25t
d= t- 175
d= t + 25
Answers
Answer:
d = 25t
Step-by-step explanation:
pick tow points on the line, the easier for me is (0,0) and (2,50). The equation options are given in slope intercept form such as y = mx + b; where m is the slope and be is where the line intercepts the y-axis. We can see that "b" is zero because the line intercepts the y-axis at 0 (b = 0).
to find the slope you use the two points for the m
m = [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex] = [tex]\frac{(50 - 0)}{(2 - 0)}[/tex] = 25 is the slope
Therefore the equation should d = 25t

Answers
Answer:
b = 7
Step-by-step explanation:
- 4(2 - 5b) = 132
- 4 × 2 - 4 × (- 5b) = 132
-8 + 20b = 132
20b = 132 + 8
20b = 140
b = 140/20
b = 7
Thus, The value of b is 7

Samuel bought 4 rolls of tape to seal boxes. Each roll contains 32.9 meters of tape. He uses 1 1/5 meters of this tape to seal each box. What is the total number of boxes Samuel can seal with these 4 rolls of tape?
Answers
Answer:
109.33 boxes
Step-by-step explanation:
The first step is to calculate the total number of tape
= 32.9 × 4
= 131.6 m
Therefore the total number of boxes that Samuel will use to seal the boxes can be calculated as follows
= 131.6/ 1 1/5
= 131.6 ÷ 6/5
= 131.6 × 5/6
= 658/6
= 109.33 boxes

1. m<1 = 139°
2. m<2 = 41°
3. x = 29
Step-by-step explanation:
1. m<1 = 86° + 53° (exterior angle theorem of a triangle)
m<1 = 139°
2. 133° = m<2 + 92° (exterior angle theorem of a triangle)
133° - 92° = m<2 (Subtraction property of equality)
41° = m<2
m<2 = 41°
3. 4x + 15 = 93° + (x + 9)° (exterior angle theorem of a triangle)
Add like terms
4x + 15 = 102 + x
4x - x + 15 = 102 (substraction property of equality)
3x + 15 = 102
3x = 102 - 15
3x = 87
x = 87/3 (division property of equality)
x = 29

Amplitude of 16 units, a period of 5 units, a vertical displacement of 3 units up and a phase shift of 2.5 units left.
Answers
The question is incomplete. The complete question is :
A sine function that has an amplitude of 16 units, a period of 5 units,a vertical displacement of 3 units up and a phase shift of 2.5 units left. Graph this function and show each step.
Solution :
The standard form of the sine function is
y = a sin (bx - c) + d
Here given :
Amplitude, a = 16
Period : [tex]$\frac{2 \pi}{|b|} = 5$[/tex]
⇒ [tex]$b = \frac{2\pi}{5}$[/tex]
Phase shift : [tex]$\frac{c}{b} = 2.5$[/tex]
[tex]$\Rightarrow \frac{c}{2 \pi/5}=\frac{5}{2}$[/tex]
∴ [tex]$c = - \pi$[/tex]
The vertical displacement : d = 3 units up
Now substituting a, b, c and d values in the standard form gives :
[tex]$y = 16 \sin \left( \frac{2 \pi}{5}x -(- \pi)\right) + 3$[/tex]
[tex]$y = 16 \sin \left( \frac{2 \pi}{5}x + \pi\right) + 3$[/tex]

What is the equation of the line that passes through the point (4,−7) and has a slope of -1/2?
Answers
Step-by-step explanation:
y = -0.5x + c
When x = 4, y = -7.
=> (-7) = -0.5(4) + c, c = -5.
Therefore the equation is y = -0.5x - 5.
Answer:
y = -1/2 x - 5
Step-by-step explanation:
y = mx + b
m = slope = -1/2
y = -1/2 x + b
-7 = -1/2 * 4 + b
-7 = -2 + b
b = -5
y = -1/2 x - 5

A family restaurant chain wants to test the market for a new menu item: a grilled chicken sandwich with chipotle salsa. They are interested in both how to market the item and the right price to charge for it. They decide to offer the sandwich at 60 different restaurants in the chain, using two different descriptions on the menu. Half the restaurants' menus will emphasize "healthy eating" and half will emphasize "value." These two groups of restaurants will be further divided in three groups, each charging either a High, Medium, or Low price for the sandwich. After a month, they will measure what proportion of customers order the new sandwich.
