Answer:

60degrees

Step-by-step explanation:

Using the theorem that states that angle at the vertex is half the difference of the angles at the intercepted arcs

Angle at vertex can be gotten by taking the difference of 119 and 65

Angle at the vertex = 119 - 65

Angle at the vertex = 54

Hence;

54 = 1/2(168-VF)

Cross multiply

54  * 2 = 168-VF

108 = 168 - VF

VF = 168 - 108

VF = 60degrees

Hence the measure of arc VF is 60degrees

Answer:

no y = 3x +15 is greater

Step-by-step explanation:

The coordinate of the vertex of the parabola is option (C) (1,-2) is the correct answer.

The set of all points in a plane that are equidistant from a fixed line and a fixed point (not on the fixed line) in the plane is a parabola. The fixed line is the ‘directrix’ and the fixed point is the ‘focus’. The point of intersection of the parabola with the axis is the vertex.

For the given situation,

The equation of parabola is [tex](x-1)^2=12(y+2)[/tex] ------ (1)

The diagram below shows the parabola and the vertex of the equation of parabola.

The general form of the equation of parabola is

[tex](x-h)^{2} =4a(y-k)[/tex]

Here the vertex is (h,k)

Now compare the equation 1 with this general form, we get

⇒ [tex]h=1[/tex] and [tex]k=-2[/tex]

Hence we can conclude that the coordinate of the vertex of the parabola is option (C) (1,-2) is the correct answer.

You can find slop by doing rise/run Or the increase in y over increase in x

You read the graph left to right just like a  sentence so if the line is going down from left to right the slope is negative :)

Answer: 1.12 Ghana Cedis

Step-by-step explanation:

First find the cost per kg:

= Amount spent / kg

= 224/250

= 0.90 Cedis per kg

In order to make a profit of 25%, the amount to charge per kg is:

= Cost per kg * ( 1 + makeup)

= 0.90 * (1 + 25%)

= 1.12 Ghana Cedis

Answer:

12.56m^2

Step-by-step explanation:

a = piR^2

The area of a sector of a given circle is 37.7 m².

Given that, the radius of a circle=4 m and the central angle of a circle=270°.

The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.

The formula to find the area of a sector is θ/360°(πr²).

Where r is the radius of the circle and θ is the angle of the sector.

Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².

Therefore, the area of a sector of a given circle is 37.7 m².

Answer:

8 m/s.

Step-by-step explanation:

18 miles = 18*8/5 = 28.8km

28.8 km = 28.8 * 1000

= 28,800 m.

There are 3600 seconds in an hour.

Therefore:

28800 meters per hour = 28800/3600

= 8 m/s.

Answer:

D. (-2, 1).

Step-by-step explanation:

y = 3x + 7

y = -2x - 3

AS the expressions on the right are both equal to y:

3x + 7 = -2x - 3

3x + 2x = -3 - 7

5x = -10

x = -2

Plug this into the first equation:

y = 3(-2) + 7

Answer:

Cost of Kid's tickets =16.66

Cost of Adult's ticket =33.34

Step-by-step explanation:

Adult Tickets=7

Kids Tickets=7

Both total = 50$

So 14 tickets =50$

Now: Lets the cost of kid's ticket=x

The Cost of Adult's tickets be 2x

=so (x+2x)=50$

=3x=50$

=x=16.67 for 7tickets

Cost of Kid's tickets =16.66

Cost of Adult's ticket =33.34
