The points (a,5) and (9,b) are on the circle x^2+ y^2= 125.
Aneli [31]

Answer:

a = 10

b = 6.633

Step-by-step explanation:

x²+ y²= 125.

In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.

<u>(a,5)</u>

x²+ y²= 125

a² + 5² = 125

a² + 25 = 125

a² = 125-25

a² =  100

a = √100 = 10

(9,b)

x²+ y²= 125

9² + b² = 125

b² 125 - 81

b² = 44

b = √44 = 6.633

A kite was broken into two triangles.
Mekhanik [1.2K]
<h2>Answer:</h2><h2>Area of the kite = 80 cm^{2} , Area of traingle = 40 cm^{2} and height of the triangle, h = 5 cm</h2>

Step-by-step explanation:

A kite is broken into two triangles

Given the base of the traingle, b = 16 cm

Height of the triangle, h = 5 cm

Area of traingle = \frac{1}{2} (b.h)

= \frac{1}{2} (16) (5)

= 40 cm^{2}

Area of the kite = area of triangle 1 + area of triangle 2

  = 40 + 40

 = 80 cm^{2}

KatRina [158]

Answer:

4 2/7

Step-by-step explanation:

It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)

_____

The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...

... 8, 5, 2, 1, 3, 5, 6

and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...

... 30/7 = 4 2/7

_____

<em>More about Absolute Deviation from Average</em>

"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...

... |0 - 8| = |-8| = 8

For 3, it is ...

... |3 - 8| = |-5| = 5
