15/y=15/20=3/4

Answer:

The 100-meter dash is over in a flash, but so much goes on in those 10 ... it and how the top sprinters approach the Olympics' marquee track and field event. ... time of 9.63 seconds, nearly 2.5 seconds faster than Burke ran in 1896. ... The total strides in the 100 range from 40-41 for Bolt to around 50 for the top women.

Step-by-step explanation:

The standard form of an equation with p = 3/2 and phi=300 degrees is; x(√3) + y - 3 = 0

The standard form of this type pf equation has the general format as;

x(cos Ф) + y(sin Ф) = p

where;

p is perpendicular distance from origin

Ф is the angle between perpendicular and the positive x-axis.

Now, we are given;

p = 3/2

Ф = 30°

Thus, the equation of these given values will be expressed as;

x(cos 30) + y(sin 30) = 3/2

We know, that;

cos 30 = (√3)/2

sin 30 = 1/2

Thus, we have;

x((√3)/2) + y(1/2) = 3/2

Multiply through by 2 to get;

x(√3) + y = 3

⇒ x(√3) + y - 3 = 0

Answer:

46

Step-by-step explanation:

Sum of all the Arcs of a circle = 360.

So, the angle of the 3 arcs is

153 + 115 + x =360

=>268+x=360

=> x = 92

*** x = Arc FG

We know that the inscribed angle is 1/2 times the amount that of the intercepted arc.

=> Inscribed Angle = 1/2 * Intercepted Arc

=>  ? = 1/2* Arc FG

=> ? = 1/2 * 92

=> Angle E = 46

Answer:

13) 27 units³

14) 160 units³

15) 189 units³

Step-by-step explanation:

To find the volume of a rectangular prism, we need to multiply the length, width, and height of the figure together.

The dimensions of figure 13 are 9, 3, and 1

9 · 3 · 1 = 27

The volume of the figure is 27 units³.

-------------------------------------------------------------

The dimensions of figure 14 are 5, 8, and 4

5 · 8 · 4 = 160

The volume of the figure is 160 units³.

-------------------------------------------------------------

The dimensions of figure 15 are 3, 9, and 7

3 · 9 · 7 = 189

The volume of the figure is 189 units³.

Answer:

(1, -5)

Step-by-step explanation:

Solve the system by setting the equations equal to each other, and solving for x:

-7x + 2 = 9x - 14

2 = 16x - 14

16 = 16x

1 = x

So, the x coordinate of the solution will be 1.

Plug in 1 as x into one of the equations, and solve for y

y = -7x + 2

y = -7(1) + 2

y = -7 + 2

y = -5

So, the y coordinate is -5.

The ordered pair solution is (1, -5)

Answer:

[tex] x = 5 \pm \sqrt{7} [/tex]

Step-by-step explanation:

x^2 - 10x + 14 = -4

Subtract 14 from both sides.

x^2 - 10x = -18

To complete the square, add the square of half of the x-term's coefficient.

x-term coefficient: -10

half of it: -5

squared: (-5)^2 = 25

Add 25 to both sides.

x^2 - 10x + 25 = -18 + 25

(x - 5)^2 = 7

Take square root of both sides. Be careful to include ± on the right side.

[tex] x - 5 = \pm \sqrt{7} [/tex]

Add 5 to both sides.

[tex] x = 5 \pm \sqrt{7} [/tex]

Step-by-step explanation:

four Point perspective

Answer:

one point perspective

Step-by-step explanation:

It is one point perspective because if you are thinking about birds eye view, you have to consider that they height a bird can fly is very very high. So you have to be thinking critically, it cannot be 4 point perspective nor 3 point perspective due to the fact, that that is worm eye view. Thus, the answer it leaves you with is 1 point view and 2 point perspective. Two point perspective is us, it would be like us watching a building (which isn't that high). Hence, the last answer you are left with is one point perspective.
