Train A leaves the station traveling east at 50 mph while train B leaves the station 30 minutes later traveling west at 65 mph. Choose the equation below that represents the distance in miles between the two trains, D, as a function of T, the time in hours after train B has departed.
Answer:
Change 45 min to .75 hrs
Distance = speed * time
Train A's distance = 55(t+.75)
Train B's distance = 70t
The equation
D(t) = 70t + 55(t+.75)

Naomi used a rectangle, a square, and a right triangle to form the following figure.
What is the area of the shaded region of the figure in
eters?
A-120 cm2
B-102 cm2
C-18 cm2
D-9 cm2
Answer:
102 cm2
Step-by-step explanation:
First you want to find the area of the entire rectangle by multiplying the 2 sides.
20cm x 6cm = 120
Then you want to find the area of the other two shapes (in this case the square and triangle). Also use the other sides to find the lengths of the triangle.
Square = 3 x 3 = 9
triangle = 6 x 3 = 18 / 2 = 9
So then all you have to do is subtract the squares and triangles area from the total rectangle.
120 - (9 + 9)
120 - 18
102 cm2

A cosine function has a period of 4, a maximum value of 20, and a minimum value of 0. The function is not a reflection of its parent function over the x-axis.
Which function could be the function described?
Answer:
○ [tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]
Step-by-step explanation:
[tex]\displaystyle \boxed{f(x) = 10sin\:(\frac{\pi}{2}x + \frac{\pi}{2}) + 10} \\ \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-1} \hookrightarrow \frac{-\frac{\pi}{2}}{\frac{\pi}{2}} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]
OR
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]
The cosine graph in the photograph on the right is the OPPOCITE of the cosine graph in the photograph on the left, and the reason for this is because of the negative inserted in front of the amplitude value. Whenever you insert a negative in front of the amplitude value of any trigonometric equation, the whole graph reflects over the midline. Keep this in mind moving forward. Now, with all that being said, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
**Moreover, both graphs have the same maximum and minimum value, but we are looking for the equation that will not reflect over the midline of [tex]\displaystyle y = 10,[/tex]which means we do NOT want a negative in front of the amplitude value, therefore we have this equation:
[tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]
If you are having trouble figuring out which graph is which, just remember that the parent function of [tex]\displaystyle y = cos\:x[/tex]never touches the origin unless it shifts one unit south or gets reflected from somewhere. In this case, the photograph on the left touches the origin because of a reflection [negative symbol], therefore the photograph on the right matches the equation selected.
I am delighted to assist you at any time.
The correct function is,
⇒ y = 10 cos (π/2x) + 10
What is Function?A relation between a set of inputs having one output each is called a function.
Given that;
A cosine function has a period of 4.
Since, The period is 4.
Hence, The relationship between period and b (the coefficient of the independent variable of the cosine function) is, (period) =(2π/b).
Hence, We get;
⇒ 4b = 2π
⇒ b = 2π/4
⇒ b = π/2
So, Now our equation y = a cos (bx) + c becomes as;
⇒ y = 10 cos (π/2x) + 10
Thus, The horizontal center line of this cosine curve is y = 10. The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.

find the value of x.
Answer:
x=110°
Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
360° - 128° - 40° - 82° = 110°
Answer:
x = 110
Step-by-step explanation
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
82 + 40 + 128 + x = 360
250 + x = 360 ( subtract 250 from both sides )
x = 110
The Shirts For All shop keeps track of the total number of white and tie-dye t-shirts it sells. In one week, 500 shirts were sold. White shirts cost $15 each, while tie-dye shirts cost $20 each. If the shop earned $9000 in revenue, how many of each type of t-shirt were sold that week?
The number of white and tie-dye t-shirt sold that week is 200 and 300 respectively
let
number of be white shirt = xnumber of tie-dye shirt = yThe equation:x + y = 500 (1)
15x + 20y = 9000 (2)
from (1)
x = 500 - y
substitute x = 500 - y into (2)
15x + 20y = 9000
15(500 - y) + 20y = 9000
7500 - 15y + 20y = 9000
- 15y + 20y = 9000 - 7,500
5y = 1500
y = 1500/5
y = 300
Substitute y = 300 into (1)
x + y = 500
x + 300 = 500
x = 500 - 300
x = 200
Therefore, the number of white and tie-dye t-shirt sold that week is 200 and 300 respectively

Answer:
The amount of money they will spend at the restaurant is $35.16
Step-by-step explanation:
From the information given in the question, we have;
The amount Jessica, Genesis, and Violet received as bill at the restaurant, X = $29.30
The amount they wished to leave as tip, T = 20% (of the bill)
Therefore, the amount of money they will spend at the restaurant, 'A', is given as follows;
A = X + T
T = 20% of X = 20/100 × X = 0.2·X
∴ A = X + 0.2·X = 1.2·X
X = $29.30
A = 1.2·X = 1.2 × $29.30 = $35.16
The amount of money they will spend at the restaurant, A = $35.16

If tan A = (7/2), then which of the following is closest to the measure of
Answer:
The option which is the closest to the measure of ∠A is 74°
Step-by-step explanation:
The question is answered using the options provided by a similar question from an online source
When tan A = (7/2), we have;
The trigonometric ratio for the tangent of an angle is given as follows;
[tex]tan\angle A = \dfrac{Opposite \ leg \ length}{Adjacent \ Leg \ length} = \dfrac{sin \angle X}{cos\angle X}[/tex]
tan A = (7/2) = 3.5
sin(30°) = 1/2, cos(30°) = (√3/2)
sin(60°) = (√3/2), cos(60°) = (1/2)
sin(45°) = cos(45°) = (√2/2)
tan(30°) = (1/2)/(√3/2) = (√3)/3
tan(45°) = 1
tan(60°) = (√3/2)/(1/2) = √3
The tangent of an angle is increasing as we move from 0° to 90°
Therefore, given that tan A = 7/2 > tan 60° = √3, we have;
∠A > 60°
The option (the options obtained from an online source are; 15°, 39°, 58°, and 74°) which is the closest to the measure of ∠A is 74°.
