Find the length of the diameter of circle O. Round to the nearest tenth.

Mathematics

timama [110]3 years ago

Answer:

Diameter = 19.33

Step-by-step explanation:

Imaging a radius line from O to the endpoints of the 7. call this line R.

Label the part of the vertical line from O to the 90 degree intersection y.

Now you have a right triangle.

Using the Pythagorean theorem:

R² = 7² + y²

also

y = R - 3

substitute for y:

R² = 49 + (R-3)²

R² = 49 + R² - 6R + 9

simplify:

0 = 58 - 6R

6R = 58

R = 9.6667

Diameter = 2(9.6667) = 19.33

a profectile is shot upward, and it's distance above the ground, in feet after s t seconds is represented by the function below.
Shalnov [3]

Answer:

Step-by-step explanation:

the curve is representing the projectile. at t=0, the projectile is on the ground.  at t=6, the projectile has finished its journey and is back on the ground.  In between t=0 and t=6 will be the projectile's peak altitude.  the point between t=0 and t=6 is t=3.  So plug in t=3 and solve for s(t), and you get 36ft.  gg

The center is (2,5) and the radius is 9
kiruha [24]

Answer:

 (x-2)2+(y-5)2=92

or

(x-2)2+(y-5)2=81

Step-by-step explanation: Center:(2,5)

The center of a circle is a point from which all points on a circle are the same distance.

Radius:9

The radius of a circle is the length of a line segment from its center to its perimeter.

The radius is typically denoted as "r" or "R".

Diameter:18

The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.

Circumference or (or Permieter) = 2*π*R = 2*3.14*9 = 56.5486677646163

The circumference of a circle is the distance around it.

Area:254.469004940773

Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.

The standard form for the equation oif a circle is

(x-a)2+(y-b)2=r2

And in our particular case:

(x-2)2+(y-5)2=92

(x-2)2+(y-5)2=81

The general form for the equation of a circle is

x2 + y2 + Ax + By + c = 0

We can get the general form by expanding the equation of the standard form

(x-a)2+(y-b)2=r2

(x-2)2+(y-5)2=92

(x-2)2+(y-5)2=81

x2-4x+4+y2-10y+25=81

x2+y2-4x-10y-52=0

I don't know which one is the correct answer? PLEASE HELP!!​
alukav5142 [94]
The answer is 1/q^30 because after simplifying, you can cancel out the p and then you get q^q-20 times q^-10 to get q^-30 which then equals 1/q^30
