Answer:
x = 8
y = 4sqrt(3)
Step-by-step explanation:
Your knowledge of special triangles tells you the side ratios of a 30°-60°-90° right triangle are ...
1 : √3 : 2 = 4 : y : x
Multiplying the reduced ratios by 4 gives ...
4 : y : x = 4 : 4√3 : 8
That is, ...
x = 8
y = 4√3

Answer:
x = 150
Step-by-step explanation:
The sum of the exterior angles of a convex polygon is 360°.
65° +80° +72° +(x -7)° = 360°
x = 150 . . . . . . divide by °, subtract 210
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.
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 of the following represents the factorization of the trinomial below?

O D. (x-20)(x-2)
Factoize those 2 questions using "ac"method must include all steps
Answer:
(2x + 5)(3x - 7), (x + 4)(x - 2)
Step-by-step explanation:
a = 6, b = 1, c = -35
? × ? = ac = 6 × -35 = - (2 × 3 × 7 × 5)
? + ? = b = 1
3 × 5 -(negative sign from above) 2 × 7 = 15 - 14 = 1 = b
[tex]\frac{1}{6}(6x + 15)(6x + (-14))[/tex]
= [tex]\frac{1}{6}(3)(2x + 5)(2)(3x - 7)[/tex]
= [tex](2x + 5)(3x - 7)[/tex]
a = 1, b = 2, c = -8
? × ? = ac = 1 × -8 = -(2 × 2 × 2) = 4 × -2
? + ? = b = 2
4 + (-2) = 2 = b
[tex]\frac{1}{1}(1x + 4)(1x + (-2))[/tex]
= [tex](x + 4)(x - 2)[/tex]

Step-by-step explanation:
find the appropriate function
Answer:
y = 0.5sin(4x)
Step-by-step explanation:
y = A sin(B(x + C)) + D
amplitude is A = 0.5
B = 2π/period = 2π / (1/2 π) = 4
phase shift is C (positive is to the left) = 0
vertical shift is D = 0

Which inequality can be used to represent this scenario?
Mikael needs to rent a scooter to get to work. The scooter charges $1.85 to activate it and $0.50 per mile Mikael has a gift card for
$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
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]
[tex]10 > 1.85 + 0.5m[/tex]
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
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
