Answer:
Horizontal distance = 0 m and 6 m
Step-by-step explanation:
Height of a rider in a roller coaster has been defined by the equation,
y = [tex]\frac{1}{3}x^{2}-2x+8[/tex]
Here x = rider's horizontal distance from the start of the ride
i). [tex]y=\frac{1}{3}x^{2}-2x+8[/tex]
[tex]=\frac{1}{3}(x^{2}-6x+24)[/tex]
[tex]=\frac{1}{3}[x^{2}-2(3x)+9-9+24][/tex]
[tex]=\frac{1}{3}[(x^{2}-2(3x)+9)+15][/tex]
[tex]=\frac{1}{3}[(x-3)^2+15][/tex]
[tex]=\frac{1}{3}(x-3)^2+5[/tex]
ii). Since, the parabolic graph for the given equation opens upwards,
Vertex of the parabola will be the lowest point of the rider on the roller coaster.
From the equation,
Vertex → (3, 5)
Therefore, minimum height of the rider will be the y-coordinate of the vertex.
Minimum height of the rider = 5 m
iii). If h = 8 m,
[tex]8=\frac{1}{3}(x-3)^2+5[/tex]
[tex]3=\frac{1}{3}(x-3)^2[/tex]
(x - 3)² = 9
x = 3 ± 3
x = 0, 6 m
Therefore, at 8 m height of the roller coaster, horizontal distance of the rider will be x = 0 and 6 m
What is the equation of the line that passes through the point (-1,-5) and has a
slope of -1
Answer:
y=-x-6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-5)=-1(x-(-1))
y+5=-(x+1)
y=-x-1-5
y=-x-6

The endpoints of line segment. CD are C(-4,7) and D(0,-3). Find the midpoint of
line segment CD.
Given:
The endpoints of line segment CD are C(-4,7) and D(0,-3).
To find:
The midpoint of CD.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the midpoint formula, the midpoint of CD is
[tex]Midpoint=\left(\dfrac{-4+0}{2},\dfrac{7-3}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{4}{2}\right)[/tex]
[tex]Midpoint=\left(-2,2\right)[/tex]
Therefore, the midpoint of the line segment CD is (-2,2).
the lenght of a rectangular field is twice its breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. what is the length of the field
Step-by-step explanation:
4.5÷4= 1.125
so each time she goes around the rectangle she's covering 1.125 km and we seed the length is twice the breadth x+2x=1.125
so 1.125 / 3 to give x which is the breadth=0.375 x 2 is equal to 0.75 km or 750 m this is the length of the field
Step-by-step explanation:
The length of a rectangular field is twice it's breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. What is the length of the field?
The distance cover in 4 laps is 4.5 km, So one lap is 4.5/4 = 1.125 km.
Let the breadth of the field be B so the length will be L or 2B.
The perimeter of the field is 2L+2B or 4B+2B = 6B = 1.125, so B = 1.125/6 = 0.1875 km and the length is 2*0.1875 = 0.375 km.
Check: perimeter = 2*0.375 + 2*0.1875 = 1.125 km and 4 laps covers 4*1.125 = 4.5 km. correct.
The field is 375 m long.
Find the distance between (2.3) and (0,6).

The measure of ∠Y is (8x + 12)°. If x = 4, find the measure of ∠Y, then classify the angle.
plz plz plz help
Answer:
44° , acute angle
Step-by-step explanation:
Given
y = 8x + 12 ← substitute x = 4
y = 8(4) + 12 = 32 + 12 = 44°
Since 44° < 90° then angle y is acute

Mia and Mario specialize in producing the item in which she or he has a comparative advantage. Then they trade one pasta dish for one pizza.. Before specialization and trade, Mia and Mario produce 6 dishes of pasta and 6 pizzas an hour each. The total gains from specialization and trade are ___________
Answer:
6 pizza, 6 pasta
Step-by-step explanation:
Now from the question we can see that Mia has comparative advantage in Pasta production and Mario in Pizza production.
Now before they both specialized, Mia's production was 6 pizza, 6 pasta. Mario also was making 6 pasta, 6 pizza.
So in total both were making 12 pizza and 12 pasta.
After they had specialized, Mario's pizza production is 18 pizza and Mia's pasta production is 18 pasta.
So we have that mia is producing 6 more pizza, 18-12 = 6
and Mario is also producing 6 more pasta.
So there is net gain of 6 pizza and 6 pasta.

A new car is purchased for 17600 dollars. The value of the car depreciates at 11.75%
per year. What will the value of the car be, to the nearest cent, after 11 years?
Answer:
The value of the car will be
4450.15
Step-by-step explanation:
we know that
11.75%=11.75/100=0.1175
so Let
x-----> the value of the car after 11 years
X=17600(1-0.1175)11=4450.15

Answer:
2×4=8
3×4=12
12÷2=6
8+6=14
Step-by-step explanation:
Answer:
17m
Step-by-step explanation: Cut the triangle in half and place it over the other triangle creating a square. We know that one side is 3m so since all the sides of a square are equal 3 times 3 equals to 9. For the rectangle 2 times 4 is 8. So finally 8 plus 9 equals to 17. The area of the composite figure is 17m.

Triangle SRQ undergoes a rigid transformation that results
in triangle VUT.
Which statements are true regarding the transformation?
Select two options.
SRE
OSQ corresponds to VU.
V
O ZR corresponds to ZU.
UV corresponds to RS.
OZS corresponds to ZT.
OQS corresponds to RS.
Sign out
Answer:
UV corresponds to RS.
[tex]\angle R[/tex] corresponds to [tex]\angle U[/tex]
Step-by-step explanation:
Given
[tex]\triangle SRQ[/tex] and [tex]\triangle VUT[/tex]
Transformation: Rigid
Required
Determine the true options
When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:
SR to VU, SQ to VT, RQ to UT
And the corresponding angles are:
<S to <V, <R to <U and <Q to <T
From the corresponding sides above, we have:
SR to VU
Rewrite:
RS to UV
Hence: (c) is correct
From the corresponding angles above, we have:
[tex]\angle R[/tex] to [tex]\angle U[/tex]
Hence:
(b) is correct
