In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?
Answers
Answer:
B. B = 70.5° or B' = 109.5°
Step-by-step explanation:
(sin 45°)/13.5 = (sin B)/18
sin B = (18 * sin 45°)/13.5
sin B = 0.9428
B = sin^-1 0.9428
B = 70.5°
B' = 180° - 70.5°
B' = 109.5°

A system of equations is created by using the line represented by2x+4y=0And the line represented by the data in the table below
What is the X value of the solution to the system if x -1 and y is 8
Answers
Answer:
x = 2
Step-by-step explanation:
From the data, we obtain the slope :
-1, 8 ; 3, - 4
Slope = Rise / run
Rise = y2 - y1 = (-4 - 8) = - 12
Run = x2 - x1 = (3 - (-1)) = 4
Slope, m = - 12 / 4 = - 3
Recall:
Equation of line :
y - y1 = m(x - x1)
y - 8 = - 3(x + 1)
y - 8 = - 3x - 3
y = - 3x - 3 + 8
y = - 3x + 5
Substituting y = - 3x + 5 into the equation 2x+4y= 0
2x + 4(-3x + 5) = 0
2x - 12x + 20 = 0
-10x = - 20
x = 2

doesn’t equal to x2+9x-22. Let’s check choice c you get x2-2x-11x+22 that doesn’t give us x2+9x-22 . You can also directly cross out choice d . Only b is the correct answer.

A bridge is built in the shape of a parabolic arch. The bridge has a span of feet and a maximum height of feet. Choose a suitable rectangular coordinate system and find the height of the arch at distances of 10, 30, and 50 feet from the center.
Answers
Answer:
Height of the arch at distances of 10, 30, and 50 feet from the center is as follow:
Put x = 10 we get
the value of y = 0.695
Put x = 30
the vale of y = 6.26
Put x = 50
the value of y = 17.37
Step-by-step explanation:
The prabolic arch for bridge has span of 120 feet and height f 25 feet. The rectangular corordinate system is
such as
height = h = 25
Distance = x
(x-h) = -4a(y-k)
x² = -4ay
60 = -4a(-25) and
where the value of a =36
therefor the parabolic arch is
x = -144y
For distance of 10 , 20 and 30 let take the feet from center then we have
put x = 10 we get
10² = -144 y
100 / 144 = y
the value of y = 0.695
Put x = 30
30² = -144y
30/144 = y
the vale of y = 6.26
Put x = 50
50² = -144 y
50/144 = y
the value of y = 17.37

Which inequality can be used to represent this scenario?

$10 and he can not spend more on the scooter
O 10 < 0.502 +1.85
O 10 < 1.85.1 +0.50
O 10 > 1.852 +0.50
O 10 > 0.503 +1.85
Answers
Answer:
[tex]10 > 1.85 + 0.5m[/tex]
Step-by-step explanation:
Price of the scooter:
Fixed price of $1.85 to activate plus $0.50 for each mile. This situation can be represented by a linear function, and it is given by:
[tex]P(m) = 1.85 + 0.5m[/tex]
Mikael has a gift card for $10 and he can not spend more on the scooter.
The spendings have to be less than 10. So
[tex]10 > P(m)[/tex]
